How to fix broken fans on EVGA XC3 Graphics Card in 10 mins
the chances are if your watching this video its because youtube is forcing you to do so
*Does this method apply to the EVGA RTX 3080 Ti FTW3?* *When the Fans are off, I would use Compressed Air to Blow Off the Heatsink*
I believe the FTW is put together a little differently, like the MSI Ventus is a little different to the Trio. But that said, most of the 30X0 cards are at least similar. Just be careful with compressed air not to hit/spin up the fans, the current generated by the fan motor when doing this can damage the board. Remove them, or ensure they are held still and don’t get spun by the air.
it is amazing how toshiba hdds are poorly covered on Internet. Everyone talks only about wd and seagate as if toshiba hasn't existed. in my place toshiba mg series is 25-30% cheaper than the other two competitors. Yes, making such video about Toshiba is an excellent idea.
I have covered them in my reliability comparisons using BackBlaze data (as BackBlaze use their drives). I am also included them in my desktop drive SMR comparison (P300), and i am currently doing a lot of performance testing on surveillance drives which includes their S300. I am sure I will look at their NaS and Enterprise drives also. They do have a small relative market share however compared to the other two, so probably why less coverage on them. I do notice they have a loyal customer base though.
I can NOT recommend buying drives off of amazon. I had ordered 2 8 TB drives. they were not properly packaged at all. Amazon just threw them in bare paper envelopes with no bubble wrap or anything. of course the drives were both dead on arrival.
I had mixed experiences here also, so I think it may be a problem with the packing processes in some places. I also had drives arrive with terrible packing and be DOA, and also had them arrive with good packing. I also had several Exos drives sent from another major UK retailer who are Seagate approved retailers, and they were basically made into bubble wrap footballs, and look like they were treated in kind, arriving with physical dents in the corner of the drive. So sadly, not just an Amazon problem. I’d a disk is badly packed, test very thoroughly, and anything questionable should be returned. You would hope enough returns would fix the problem, but I guess with a seller like Amazon it barely moves the needle.
I hope they have data center quality and not lose their data like a normal CD
Thanks!
Pleasure, and really appreciate the super thanks also. 🙏
Thank you, Was looking for drives for a 2 bay mirrored NAS setup. Thinks for the information on checking them.
Pleasure, thanks for taking the time to leave the comment.
The worst part imo is that SMR often isn't even that much cheaper and isn't really available in over 8TB. I have a lot of 16 and 18TB HDDs in my UnRaid Server and I would love to put in some SMRs instead of CMR since it's mostly just a lot of files being read. Sadly the biggest I can find is 8TB and it's not cheaper then any 16 or 18TB CMRs, generally 2 Euro or so more expensive per TB. And I would also need more which would not only increase my power consumption, but also the physical hardware I need in SAS expanders and also the mechanical waste. Also thank you very much for all your HDD videos. It's rare to see someone make informative content about storage and especially HDDs and the fact your content is well produced makes it even rarer and more appreciated!
Thank you for the kind feedback, I am always working on making the content better and appreciate the encouragement. Its definitely a journey becoming a content creator. As for SMR, it is odd to me why SMR seems to be most available in the smaller disk sizes, and not the larger. Not that I am a fan of it, but I would think the larger units is where the larger cost savings could be realised. Rather cynically, I wonder if its shipped to a market that is less likely to be informed about it. But again, the fact that the prices are often not lower, something again is odd. Maybe its platters that didn't meet QA and can't be used in the other products. I would love to get to the bottom of this.
Last few years, new Seagate Exos Enterprise drives have been cheaper than the domestic retail drives. For my production NAS I buy new drives and re-cycle my own older drives into JBODS and Freenas. I've used drives junked by work as they are fully traceable and so far have been reliable, mostly SAS but fine in NAS or Dell servers.
I have 2 10 year old reds still going in a synology
I have a pile of failed disks on my table right now. It's a foot tall. In the pile there is a single Toshiba, a single WD drive, and the rest all have the work 'Seagate' on them...
Great analysis of the data! I have used about 10 Seagate drives over the years, and I saw 3 failures. I have used over 25 WD drives over the years, and have only had 1 failure. My personal choice based on experience is clear - WD
Thankyou! 🙏 My personal experience with Seagate has been good. I had some WD reds fail but they were at around 8 years run time. So I think it’s interesting to look at a really big dataset and see what it shows.
NEVER go 2nd hand on tech it is a crap shoot
Just bought a 10tb hgst drive for 85 bucks. Hope it lasts for a while
A few years ago I built a NAS, and I splurged on Iron Wolf drives. I believed they were better than Barracuda drives, but I didn't know why. Now I know.
Good deal, SMR drives in RAID arrays can be real trouble. Especially during RAID rebuilds when you need that trouble least.
@@sometechguy If you know what you're buying then there isn't an issue depending on your use case. But these drive makers keep going out of their way to obfuscate this. The WD Red drives where there are 3 variants (regular, Plus and Pro) really seem to be made to scam consumers who, even if they know what they want, will find it difficult to spot that single C or S letter difference in the drive spec sheets.
But not all drives are designed for high performance. NAS & server are typically durable. Lower spin 5400 etc to keep wear & tear minimal. The performance drop may be intentional. To keep power consumption, noise, temperatures optimal.
This points are true, and the balance between Enterprise, NAS and desktop drives are influenced by this. Unfortunately SMR drives use more power over time, endure more component usage and are noisier. All due to the nature of the addition writes and the cache cleaning process.
summary there is no difference between them.
Thank you for this!
A pleasure, hope it was a help.
I loved Quantum drives back in the day. I've used Sandisk drives in phones and especially cameras for a long time as well.
I was also a fan of quantum, I remember the Fireball drives, I think 500Mb or so. So many brands to choose from back then.
@@sometechguy I'd forgot about the Fireball!!
I have all three drives types, and if you don’t think Exos are louder you need to have your hearing checked. If they are in a closet somewhere no big deal, but if they are on your desk you are going to hear them
I would like to see test of surveillance drives, since they are cheapest on my local market. I was tempted to get one, but then looked at recertified 12/16tb options for the price of 4tb ones. Too sweet or scam?
I did a video looking at the renewed drives, which seems to include recertified as well as just ‘used’. I think there are some good deals there, but got to be through in checking what you get. I also just picked up a manufacturer recert Ironwolf pro to test, and it looks solid. The surveillance are interesting as, like you say they can be well priced. But have to be a bit careful of SMR there also. And the testing I am doing is checking how they really perform, as the firmware is tuned a bit differently. Testing still happening as it takes some time. But should be done with that before long.
My problem here is the term "Renewed". NOTHING is new about these drives, NOTHING is refurbished. Apart from having their data scrubbed, they are just USED harddrives. If they'd had their heads replaced or their platters, THAT'S a refurbishment. In fact, it's a bit of a stretch even saying that updating firmware is a refurbishment.
Recently use a CMR Enterprise Hgst 4TB HDD... With 200MBps read/write, and significantly faster random read/write, it's a world apart from SMR drive. Migrate some games into it and the speed only take minor hit, especially games lighter than 20GB.
A very informative video, thanks. I really found it hard to hear all your dialogue however. Some words were spoken incredibly quickly, or were dropped off at the end of a sentence.
Thanks, and appreciate the feedback. I try not to speak too quickly, but I am a bit guilty of this sometimes. And realise much of my audience may not be native English speaking, or find my accent easy either. Will always try to keep improving on this, so the feedback is valuable. Thank you. 🙏
@@sometechguy, what a lovely response, thank you.
here some advice : 1.WD drives HC510 - HC520 - HC530 are used very heavily around 40000 hours so not good, but if you want to buy it at least buy the drives that end with L4 - L0 not 04 - 01, they officially recertify from the manufacturer and come with under 100 hours of use and don't need power disable, AND MAKE SURE TO TESTED the drive with at least 4 pass of full write read cycle, it will take 2 day to compete and if the drive fail you return it before the 90 days. 2. as for 8TB - 10TB drive they very old and come with 50000 to 55000 hours of use and very common to see bad sectors so DO NOT BUY USED. *may be better to buy new cheap external hard drive and shuck it...
Fantastic video, thank you!
Thank you! 🙏
I own HGST 3Tb. It sounds like a coffee maker when is accessed. I tolerated it for whole year then switched to Toshiba P300. it has 7300 power on hours now. CristalDiskInfo shows 29C/Good. No bad clusters or other errors.
Seagate IronWolf Pro was my last one with 24TB. LOVE IT!
Only buy refurbished or reconditioned stuff if you don't value your time. Personally, the price difference vs a new one (which is always minimal) never justify the risk you take and then problems you will get from them. It's a shame because renewed stuff is a good option for the environment.
'renewed'? Really? Go buy em folks. They're 'renewed'.
Smr is only good for write once read many use like how we used to use DVD-Rs
They need to be 20% cheaper the cmr in my opinion but since most of the cost of drives is the cost of materials there isn't the room to drop them by that much
But and it's a big but; Hitachi, Seagate/Maxtor and WD are all owned by WD
Maxtor are now owned by Seagate. Hitachi divested their HDD business, which then bought IBMs HDD business to form HGST. HGST was then bought by WD in 2012. However, this video talks about WD vs Seagate (as well as Toshiba) but they are certainly entirely different companies and WD do not own Seagate.
I clicked off after 3mins! The rambling made no sense...
I would still uy new since you get a long warrantee, which is the manufacturer having such good faith in the product that theyre willing to bet money on it.
I've got SMR drives and my experience has been a nightmare! I had a Seagate 5TB external drive which, in a nutshell, trashed itself and all the data on it. There's no way I'm buying any SMR drives as the risk is just too great for it to all go horribly wrong. The worst part of my experience was that the drive was a gift so I had no proof of purchase and therefore couldn't do anything about it. I was using the 5TB Seagate as an archive drive as, at the time, I was desperate for storage space. I was transferring large video files of tens of gigabytes each. Thinges seemed to be going well, until I went to delete a file and replace it with another one. The is where it all went horribly wrong. At first it just seemed to be a problem of slow data tranfer. Eventually, the transfer appeared to have completed. The drive still made noises, though, but then the devices onboard power management shut the drive down. I assumed all was well and had no clue my drive had just trashed itself. A day or so later I reconnected the drive only to discover the true horror of the situation. I'm assuming that the only data I was able to recover came from the CMR cache area on the drive, everything else was gone and it was data I was never going to get again. I tried leaving the drive connected for days on end to see if it would sort itself out, but it never did. A very painful lesson was learned. I now only ever buy drives I can confirm are CMR. There are no good reasons for using SMR drives.
I thought that smr was only used on large drives, like 16tb plus. It seems that smr drives would benifit from having some flash storage on them, even if its only 32gb or something, it would cost basically nothing to include, and it wouldn't even have to be super fast flash either.
Seagate did this with the FireCuda hybrid drives which were discontinued roughly 5 years ago. The 2 terabyte drives SMR drives used 8 gigs of NAND cache. The problem is it combined the reliability problems of SSD into a hard drive and people found that their drive would suddenly not be detected by the computer, which is the common SSD failure mode. So instead of the drive going into a failsafe mode allowing the disk to still be read when its very abused and underprovisioned NAND died, it bricked the whole thing and your data was gone. Tons of people didn't even get a year worth of use out of these things and I remember examples of people who lost them after a few short months. ..just no, it was bad. DRAM cache would make some sense, but if you shut the machine down before it's written to disk, that data doesn't get written, so it doesn't work like an SSD with built in PLC where it continues writing from the DRAM using very fast pSLC mode with capacitor power to save the data rapidly.
I've bought several of the "water Panther WP Arsenal" drives. None of them had more than 10 hours of uptime on them. For general home use I think they're a great value. I've had 4 of the 14TB models in service since June of 2023 with zero issues.
For what it's worth, I bought a 4Tb WD drive to replace an older 3Tb in my personal system, cloned three partitions to it successfully, and two days later it failed to the point where it could not be initialised by Windows or accessed in any way. I have several drive recovery apps and none of them could access the drive at all, even as a raw drive. Luckily the old 3Tb was still functional, but this should never happen.
excellent content, very informative
Appreciated 🙏
I purchased "renewed" drives from amazon. I have been using them successfully for 6 years. Like any used items one can get something with lots of life left or something near to death. It is mostly the luck of the draw rather than the process of refurbishment. Refurbishing the drive means dusting it off and erasing it.
I bought 5 x 16TB Seagate X18 Exos drives, these were 'Recertified' drives, 1 was DOA, 1 died after a month, they were refunded without issue through Amazon, and the Amazon agent confirmed they have 2 years warranty.
Did some research to figure out all these acronyms... Originally all HD used longitudinal magnetic recording (LMR) which laid the data down like a road stripe (Vertical to head travel) this was then switched to perpendicular magnetic recording (PMR) which is horizontal to head movement. Now known as CMR, which is laid within the track. SMR is "Shingled" PMR where the magnetic stripe overlaps the adjacent tracks (Narrower track width). This overlap distorts any valid data recorded on adjacent tracks and has to be "Touched up" by the drive controller which is what causes the delay. All of these stages were to increase storage capacity and since most people use platter drives for mass storage now (As I do), the reduction in performance is not a huge problem. In my case on-board backup or NAS where I occasionally write files to. If your rendering videos or some other data intensive use it would certainly pose a problem, I don't think it causes a big risk to data loss especially if you use RAID. Seagate seems to call their method "TGMR" which sounds like SMR by their description.
Even if you use raid, when a drive fails it's gonna take substantially longer to rebuild, which might nt be a big deal with 4tb, but if you're running 20tb drives, the likelyhood of another failiure happening happening while it's being rebuilt is much higher due to the slower speed.
You might like or dislike WD, but what I've observed over years of Backblaze data is that HGST drives, both before and after the WD acquisition have been more reliable than similar Seagate products. I know someone will jump in to tell me how Seagate drives have never failed on them and I can tell you the same thing - None of my 12 Seagate disks have failed in my NAS over the past 5-6 years that I've had them. BUT, that is personal experience and a fallacy. If I am going to buy new drives today, it would be from the HGST lines that have been rebranded as WD
I was and still am a big fan of btrfs, but after some really disastrous issues with it over 5 years ago, I am not willing to take that risk again. I've moved to zfs, with truenas and just zfs installed on linux and though I know btrfs merged a fix for raid5 recently, I am not even going to bother testing it. I assume a lot of hobbyists own Synology and run it with btrfs + shr and it is relatively stable, but I don't think Synology offers that combo to their business customers and I suspect stability and risk of data loss are the primary reasons
I got some Maxtor recertified disks and it was weird they were big and cheap and the labels on them were new but two of them clicked and made a weird "zzzt" type noise when read/writing. What was really odd was that the SMART data said it was 0 hours / 0 power cycles, BUT there were tons of read errors. I did manage to return them to Amazon. I didn't bother next time and just bought new from WD.

What software do you use for these animated graphs ??
I have experimented with a few options, but these use canva, and I quite like them.
Very interesting video for hobbyist home lab dude that's planning to make some smaller raid box. However there's one thing that stands out really heavily for me. IF they're "renewed" they should last possibly for very long. However I'm under heavy suspicion that there's nothing renewed on these drives, but they're infact just plainly decomissioned drives as preventive maintenance from some facility, which makes them inline for the vid. Has someone stumbled into some investigation what these drives for sure are? Meaning renewed or decommisioned? After all, there's huge difference. Even worse, note I haven't checked if this is in fact possible, but highly likely it is. I hope someone doesn't buy decommisioned drives and write falsified usage data to their memory. I wouldn't be surprised about this as many have apparently receided dead drives. Sure transit can damage drives, but getting bunch of doa drives on some shipment that's in good condition and well packaged is always bit suspicious.
Unless you're happy with potentially losing your data at any moment, I really would not recommend refurbished drives to anyone. After they've been refurbished by a 3rd party, you really cannot guarantee any data integrity that comes with buying straight from a reputable manufacturer, especially spinning disk drives. SSD's.. maybe if the refurbisher is reputable and the NAND is in-tact with it's original SMART data, but spinning disks, after you open them up, you really can't trust them to be reliable.
Sideways is not optimal for the HDD rotation Axle making friction way bigger than it could be in a horizontal position
This is an urban myth, unless you have hard info to support that. All the major manufacturers state that orientation doesn’t matter for drive operation. I wouldn’t change the orientation when the drive is running, as gyroscopic affects are quite strong. But really, it’s best not to move drives at all during operation due to this affect and the laws of preserved momentum putting strain on the drive. But orientation isn’t a concern. And if it was, I am sure that drive manufacturers and array producers would be stating that and building appropriately. 😁
@sometechguy It's called Physics, but go ahead, both products makers really like you throwing your $ away; goof luck with that
Haha, I’m now going to reply to all requests for sources with “it’s called physics”. Why didn’t I think of this before 😅
When someone invokes 'physics', it's all over. I can't argue with the basic laws of physics. 😢
@@sometechguy Well we live in such a world, so you should analyze things from that perspective always, and not from "is an urban legend"; things that make sense
