Depends on the NAS.
These are SMR drives, which are unsuitable for RAID applications due to their huge resilver time.TL;DR: they will work fine until you get a drive failure, where you could be waiting weeks for a parity rebuild which means you are at high risk of another failure and losing the data entirely.
does that mean it will be fine for unraid applications that runs 24/7?
Personally, I think yes.
I use a bunch of these in my Unraid server. They still aren't very good with managing large chunks of deleted data if you write more than the drive capacity over time due to a missing TRIM command, but at the cost per TB it's worth it as long as you are aware of it.
They are low power usage and run quite cool. If one fails just replace it with a CMR drive for the rebuild.@thedean: As I've posted before, I've been running 8 of these 24/7 for 6 years, with one failure/replacement required. And also 8 of the 4TB versions in another NAS for longer than this.
@gadgetguy: I know you love to share your anecdotes, however many tech journalists have tested resilver times of SMR drives and found them woefully inadequate in RAID applications.
As I mentioned, the reason they are not recomended is due to the resilver time:
"in the event of a drive failure, during RAID rebuilding, an SMR Drive will likely take considerably longer to repair on particularly full arrays and often the required idle time for data arrangement is not possible, likely leading to RAID rebuild and RAID resync issues and potentially lost data. This is the main crux of the argument of most people against the use of SMR drives in a NAS server.".Source: https://nascompares.com/2021/04/22/smr-cmr-and-pmr-nas-hard-…
@thedean: I replaced one drive running in SHR2 and it took about a day to rebuild. Perfectly acceptable.
A backup strategy and appropriate RAID levels should be part of any NAS usage.
It's not an anecdote, it's personal experience. I think these SMR RAID scare stories are just that.
@gadgetguy: SMR large file copy test:
https://www.servethehome.com/wp-content/uploads/2020/05/SMR-…The resilver test:
https://www.servethehome.com/wp-content/uploads/2020/05/SMR-…Sure, if you don't care about write performance, then you might prefer to go for SMR. However, for NAS, there is more to it then just CMR vs SMR. There are other features in proper NAS HDDs. It's all relative, if cost is more important than reliability and speed, then sure, SMR HDDs are more cost effective.
@netsurfer: I agree with all your comments.
The issue with the large resilver time is on the likely hood of drives failures during a resilver.
Most people buy all their NAS HDD's together, and if one fails on the right end of the bathtub curve, then there is a much higher chance for failure on the other drives which are likely from the same batch soon after.A resilver puts these drives under significant pressure, and increases the chance of a failure before the resilver will complete. While anecdotal, there is loads of reports of this on reddit during WD SMR gate.
If you are buying drives for a NAS in RAID, given this possibility, it may be more cost effective per usable TB to just buy NAS purpose drives given you are losing capacity but potentially not gaining redundancy.SMR drives are great for bursty writes, but for sustained or NAS applications, just not recommended.
@thedean: gadgetguy mentioned he uses SHR2 so that makes it difficult for us to argue against that. With SHR, when a drive failed, the NAS can still access the full volume data - albeit at a slower speed. So it's difficult to argue super slow resilver time is a big issue.
It's good to know that there are people using SHR/SHR2 based setup mostly for its flexibility, rather than speed / performance.
these are not meant for nas use
don't use this for a NAS they won't last long there not designed to be put in NAS's you need to look for HDD's like the NAS branded ones that are designed to go for 24/7. These hard drives are desktop PC drives not designed to be used 24/7
Nope, these drives have shingles - they use crappy SMR recording, and probably have other corners cut.
You can use them, but when things go wrong, rebuilding things will be a slow nightmare.
With all streaming services like Netflix, Disney+, Paramount, Prime all dirt cheap per month, why do you need this?
Not everyone uses hard drives to store visual media.
you mean p0rn?
All the streaming services is why you need this
you mean piratebay ?
Bumped into a mate recently… Even that mate has moved away from piratebay. Apparently, there are streaming services for pirated movies and TV series etc…
I just use proper streaming services. Much easier.
@netsurfer: I've recently discovered what your mate has found. It's a very grey area, but it's better than having 5 different streaming services and scrolling endlessly through each one before deciding to just watch The Office for the 4th time.
Even better - private trackers
Because I don't like the idea that any of the aforementioned can take away content I might want to watch without notice. Because these streaming services will restrict or revoke content on the basis of current events (take Netflix and Chris Lilley for example - not a fan of his content but the principle applies). Because you need to know which streaming service has what content? And then, of course, because you only have access to content for the life of the subscription.
Just a couple of 'hypothetical' reasons why. :|
Disclaimer: I don't do illegal stuffs. I promise, Mr. Copyrighter.
The reason for moving to streaming service is now "cost" related. Is it worthwhile running your NAS 24x7 for videos? Ripping UHD blu rays you own currently is a huge pain. If you want it to be cost effective, you need to get certain BD-RW drives and do a firmware patch. Then, rip the data from your original UHD blu rays.
Also, there is the hidden cost of time. Sure, I own Avengers Infinity Wars and Endgame UHD blu-ray discs, but it is much easier to watch from Disney+ (like I mentioned, a pain to rip UHD blu rays). Disney+ free trial from GamePass Ultimate means I get to watch all Marvel movies and TV series legally for free. Good luck getting the originals at that kind of price. Pirating route… I've heard there are now dodgy streaming services for those as well.
Watching UHD blu ray discs on a PC is a huge pain, there are so many requirements. Honestly, it causes more pain for the owners than addressing copyright issue. A lot of us have AMD Ryzen based systems… and that means no UHD blu-ray playback on those PCs.
Good on ya mate! You do you! :)
Though I'm struggling to find the relevance in your comment. The question was "why do people need this", which I've justified in my own use case and can see a couple of answers below that support this.
Can't see a "why do streaming services exist" question above. ;)
Perfect example for me, Star Trek Discovery.
Right in the middle of re-watching Season 3 for upcoming season 4, 2 episodes left and days away.What happens? Removed from Netflix.
Netflix knew I was watching, their analytics would have known who was waiting for Season 4. Did they notify or warn us? Nope.
Assholes.On one hand, I totally agree that the streaming sites are no longer the attractive service they (Netflix) debuted as.
On the other hand - They've probably done you a huge favour by taking away that garbage series.
Yeah, it's more the content license lapsing and Netflix not renewing it because not enough people were watching it. It doesn't make it any less frustrating when it does disappear, and it proves my use case to a tee. Netflix could have at least given you a month's notice or something to say they weren't renewing their content license for STD… like, it's the courteous thing to do! haha
Games for me. I have a 500gig SDD as a main drive so I need a big HDD to play games that are also large but don't need the speed of an SSD or to even store/swap out from one drive to the other to take capability of loading speed.
Big games now barely run on HDD like Forza 5 which has massive loading issues during play not to mention the long load times.
I purchased a 1TB SSD solely for games I play regularly.
Very much worth it! I can start driving in FH5 in around 60 second assuming I hit "Start Game" and then "Continue" as soon as they come up… one day open world games will just load straight in.
In some cases, this is already the case.
PS5 games often don't even need loading screens, and fast travel can be instantaneous.
Example is GoT Directors Cut, which removed the loading screen when fast travelling, and instead does a 1 second fade to and from black.Xbox series X and Forza 5 literally playable in 10 seconds. Crazy fast drive in it.
Obscure films, foreign films, etc?
Good price - resilvering times are irrelevant - rebuilding a big disk like these when one fail will always take time. If you are worried that at resilvering another drive may fail and you lose data, then your setup (and backup ) strategy is bad (missing).
Large file copy time is inferior:
https://www.servethehome.com/wp-content/uploads/2020/05/SMR-…15 times inferior resilvering time might not be an issue for some people and having NAS offline for a day or two isn't going to be a big deal for most people.
https://www.servethehome.com/wp-content/uploads/2020/05/SMR-…To be honest, it depends on what NAS you have. If you have a $100-$200 el cheapo NAS, then getting proper NAS HDDs might be an overkill.
It may be relevant if you got say jbod in 2 disks or are using crap/hardware raid andl Iike to dump 4k videos o it, but I bet most people will have a SSD for that…
At or above 2 drives, you got at least half a GB of cache (e.g. raid-z), which is more than enough for archiving/ network retrievals (media consumption).
If you are very relaxed on the specs, even if these reach only 100mib/sec sustained ( maybe you are using NTFS…eek) you will not be able to max them out by serving over the wire…
It's a good price, but with shipping, it comes to $5 less than what the total is at Amazon.
Yes but Amazon are a terrible company. One of their warehouses was destroyed during a cyclone and 6 people (profanity) died because they didn't want to send people home. And jeff bozo decided it was a great day to dribble some shit about space instead of even acknowledging what happened.
True. But u buying or not buying these disks from them isn't gonna change anything with Amazon… Just be a realist…
Is this good as a back up drive if I get an enclosure for it?
For those of us who are into specifications, these drives are rated for 2400 power-on hours per year (6.57 hrs per day) so running 24/7 is not ideal. Also, workload rate is 55Tb a year. Great drives for archival storage and light use.
personal anecdotal evidence has left me with an approximate 4 year full-time on lifespan for the seagate barracuda drives across 2 NAS systems (4y 2m on the 2TB drives & 3 y 10 m on the 4TB) . Your mileage may vary though, at that point one failed drive tends to lead to a cascade failure of bad drives on rebuild.
Could anyone please advise whether this is good for NAS?
