buying a recert means the smart data is wiped probably from seagate and sometimes the checks are even better than new drives coming off the assembly line. Which seagate claims.

What did you say???

Paid $250 for an 18TB WD Gold. This doesn't seem like as good of a deal as some of their other deals have been. Frown

Well, if you buy 2 (or even just one) you can easily have a NAS. All you need is a spare PC and to load up OMV/TrueNAS/unraid/whatever.
Boom, Done.

Which one of those would be easiest to setup for an old man like me?

Edit: I thought I was basing my comments regarding Exos drives on good information but it's time to be humble and admit my information was out of date (from years-old BackBlaze and other data).

You should really buy 5 for that nas you don't have yet.

I bought a couple Exos drives from this seller. One is fine but something definitely seems wrong with the other. When powering up, I can sometimes hear it taking multiple (sometimes a dozen+) tries to calibrate. It will eventually succeed but I really don't think this is normal. I regret not sending it back during the return window. It passes all the tests and SMART shows nothing out of the ordinary but I don't trust it at all.

Seagate Exos are among the most reliable drives currently available. If you had a Seagate fail ten years ago, I'm sorry, but shit happens. If you really care about your data, you buy these and you back your data up properly. Personally, I only buy these new so this deal isn't for me, but I'm still here saying these are excellent data storage for the dollars. The MTBF and manufacturer warranty speak for themselves. For a third-party seller to offer a two-year warranty on recertified drives, they gotta have a lot of confidence in the underlying tech.

If your data is valuable, you buy Seagate Exos. Maybe next year WD will be the best, but not right now. Right now these are the best drives money can buy.

Upon what are you basing that assertion? The Backblaze statistics I've seen would seem to disagree (not that they shouldn't be taken with a grain of salt). Personally, I don't have enough drives for MTBF to be of significant meaning to me and I suspect that's also true of most others here. I also don't take warranty (manufacturer or seller) to be all that indicative of drive quality or lifespan. Plenty of crappy companies will offer impressive warranties because they know they help sell drives and often won't really stand behind them. Just look at all the cheap, bottom-barrel SSDs that cover more TBW than quality brands like Samsung and Crucial. I'm not saying the same is true of Seagate or this drive, just that people are often too quick to think that the warranty is indicative of drive quality or lifespan.

When I popped a 16tb drive into my old USB drive reader it couldn't recognize it. What external enclosures are you all using to test the drives before putting them into service in a nas?

I have one with the JMicron JMS578 controller and it was able to recognize the drive. My older one, with a VIA controller would spin it up but not recognize it.

I disagree. I run multiple windows servers (business and personal), some with parity, some without. Easier to use, more versatile for me.

It's a matter of personal preference.

Windows storage spaces does most of not all of the useful things in the filesystem that the free NAD software can do.

backups are far more important and useful than parity on a dollar per dollar basis ESPECIALLY for home users.

I prefer an extra drive with a 12hr sync over an extra parity driver personally.

You should check out snapraid. Prior to moving to unraid I ran tiered SS on windows and used snapraid to "backup" my volumes and it also has checksumming. Free, go check it out. I also used drivepool which does cost $$$ but what it does is way more flexible than SS. The nice thing about snapraid is the "parity" drive doesn't need to be the size of the entire drive, just the max size of pools you want to protect, and it can restore at the file level. My only "backup" at that point was to idrive.

Guess what the failure rate of all mechanical hard drives is: 100%. It's when. A drive w/ 2.5m MTBF is sure to handle home user duty without a sweat. Most people don't understand hard drive AFR and they also don't typically keep the drives in datacenter temps/vibration/humidity so anything you hear on the forums or anecdotally is from the 99.9% who have never touched a multi-million dollar array or even understand environmentals. Their data is bogus to all but them, enterprise hard drives are far superior to any consumer drives by far and for the home user who may have 1% duty cycle they fail prematurely (in order) heat, vibration, upstream corruption, firmware (system, drive), mechanical. That is not 100% absolute, there are always sampling errors. Granted Seagate did have a bad run on firmware but I think that is almost 6-8 years ago now not on current DC drives but that DID leave a bad taste that still iingers to today like ye ole IBM deathstars. There are three primary OEM left: Seagate, WD, and Toshiba. All the drives are made in the same plants (within an OEM), the same region, and with somewhat different components and different stickers or gimped firmware. Its the same scam they play on us for tools. Oh Milwaukee is so much better than Ryobi, LOL.

BTW for those interested these are recertified by Seagate not a third party, so go ahead and save some serious $$$. They have Ultrastars too, if you want "the best" for maybe $10 more dep upon capacity.

Got one in the last round at this price. Well packaged and a solid deal. I wouldn't use it in a non-redundant system but in a raid, it's a no brainer.

Well said. As a home user it's not like I lose business or money if I fall below 99.99% uptime. Even spending a day or two recovering really isn't a big deal under normal circumstances. If I permanently lose my data I'm in a whole lot of trouble though.

Another reason I do it with an extra sync drive instead of a RAID is that RAID doesn't save you from user error. User error is FAR more common that HD crashes or malware. Nothing like accidentally deleting a folder or trashing some file names and being able to get them back from the 12hr sync drive.

Try making decisions based upon data instead of anecdotes. It will serve you better!

Well. Who would fund a double-blind, statistically significant controlled study for hard drives?

https://arstechnica.com/gadgets/2023/02/new-data-illustrates-times-effect-on-hard-drive-failure-rate... [arstechnica.com]

So most of my computer-using life used roughly equal number of Seagate (and the brands it bought like Maxtor and Connor) and HGST drives and they are the two extremes of the reliability spectrum.

My own anecdotal experience matches the stats in this one more: I had at least 10 times more dead Seagate than a HGST. Actually only one HGST (after Deskstars) I had failed because I dropped a screwdriver on the drive while it's running when I was in a hurry and not thinking straight.

You both don't need parity because you don't mange any significant space that requires it. Windows storage spaces is trash. Anyone that knows anything about computers knows thats true nas or unraid is a superior solution to managing data.
Even a basic NAS from synology would be preferred . Anyone buying multiple hdds should be using parity
