Why are you not supposed to use one NAS drive in a regular PC? Aren't they supposed to run 24/7 and never fail?

They are so much cheaper than regular drives so i'm not sure what's going on with NAS models.

Typically, drives meant for dedicated storage devices are slower than "working drives." You trade speed for reliability.

You don't have to consider this in generalities though. Go find two drives to compare and look at the raw advertised specs. Decide for yourself. You might find that there archival drives are plenty good enough for you.

But both NAS and regular drives are 7200 rpms with the same amount of cache.

Isn't that the same performance?

If you're just using them for data storage and put all your programs on an SSD, they're fine, even preferable.

I have 5 WD Reds on my desktop (and a 6tb on the way) - They're great and I've never been inconvenienced or noticed any problems.

That was supposed to be 6th, but it also happens to be another 6TB.

Not necessarily. Check sequential and random read/write speed benchmarks.

I did some Googling.

Time Limited Error Recovery applies to all NAS drives because they're meant for RAID. It reduces the time for the drive to fix errors because RAID is intolerable to it.

Won't NAS drives in a non-RAID configuration fail much faster because of this?

I have 2 WD Reds in my PC

for movies and TV it's more than good

REDs are not any better than BLUEs. Literally same shit except REDs support this one feautre i forgot about which is useful for some raid configurations in some rare cases.

this? TLER

Yeah i think so. I remember this feature is not always useful and more often unneeded and better without it. Depends on OS if i recall correctly.

Correct, I discovered the file system ZFS manages something similar to TLER, probably couple more file systems doing the same

if you're running say, a 20+ disk raid for important business shit 24/7, would you rather;
a. a disk which hangs for a minute trying to figure out a bad sector
b. a disk which just bails on it and lets the system deal with the result (which it can if you use something like ZFS)

it's useful in a redundant setup, but might cause higher data loss in other situations (single disk, no redundancy, like 99% of home users)

That's what got me worrying.

So NAS drives aren't good in a non RAID configuration for regular desktops

Everything is coming up Millhouse!

not really, but then again, if you're not using redundancy, then you clearly don't care about the data stored on it

Redundancy isn't really making your data more safe though...

Also regular drives might have power saving / sleep state caoabilities. The reading head of drive parks itself in idle. Green drives have very agressive idle state power saving. The reading head parks itself between every write/read.

it is when coupled with checksumming (which zfs also does), if a disk in a zfs raid returns a bad sector, zfs will detect it and overwrite it with good data automatically
overwriting a bad sector causes a reallocation of that sector, making it logically good again

in a no redundancy scenario, a bad sector is simply lost data, you can overwrite it, but you have no way of know it was bad (without checksums) or what the good data was (redundancy)

That's literally what it does

I wasn't aware of that. Head parking when something is being written or read is a pretty serious case.

I use this to keep my archival drives spinning, no idea if it keeps the head parking off the drive but I never have load issues when I decide to use it.

True, that makes sense

>Why are you not supposed to use one NAS drive in a regular PC?
>NAS
>one drive
Because that completely defeats the point of a NAS, you need multiple disks to not only attain lots of raw storage space but you also protect/mitigate the data from being lost by using RAID.

The 8TB WD Red is inside the WD MyBook External backup, its $180 right now.

I bought 3.
Then 1 more.
Got 32TB if big dick swinging RAID0 storage.
Yes, RAID0. I dont care about the data, and its backed up to like 4 other places.

Probably got another 12TB of externals lying around. new RAID is only 15% full

>They are so much cheaper than regular drives
Wait what? What are you comparing them against?

WD Red versus WD Gold, IronWolf vs Barracuda Pro

WD Gold is an enterprise SATA drive. Regular consumer would be Blue (generic), Green (low-power), or Black (performance).

They don't sell Black and Green anymore. Green became Blue and Black became Gold

Greens don'y exist anymore

Gold was previously "Re." It has TLER and other RAID-oriented features, it's not a replacement for Black.

>WD Gold, IronWolf vs Barracuda Pro
None of those are regular drives... Hell, WD Gold is marketed for datacenters.

Regular drives or WD Blue are a lot cheaper than WD Red.

amazon.com/dp/B01LNJBA50/

looking at the blue specs, most are 5400rpm, so i'd say it's not green that is gone, but blue
"blue" now is what green was before

this reminds me, fuck, that I'm down to 150GB free out of 9TB on my server's storage.

That's what he meant.

"NAS" drives and enterprise drives usually have error correction turned off because it's based on the assumption they're going to be placed in a RAID environment (not RAID 0, actual redundancy) and error correction will only cause the drives to be dropped from the array as unresponsive.

TLER prevents this from happening, but it could be a danger if you run the drive stand-alone as it won't run error correction that a conventional desktop drive will run.

cool blog post

I prefer hardware with a 5 year warranty. Most of the reds only come with 3 years.

You can spend extra on a RED Pro.

WD Red is literally a Green with firmware meant for NAS and less aggressive head parking

It has extra stabilising hardware, especially the PRO models.

It must suck being wrong so often.

Red Pro is kind of niche. Gold sells a lot more units and it's not unusual to find them for slightly less if you're buying bare drives.

WD Red Pro is a Red which is a Green with NAS firmware

Warranty is longer on the Red (3 years instead of 2).

>extra stabilising hardware
Lol what. Duuuude. Citation needed.
