It's about time to upgrade my storage, and I'm looking at HD prices. The consumer grade drives, like WD Caviar, have increased along with everything else in the current wave of inflation. A 4TB Caviar Black is running close to $150 now, up from about $120 a couple years ago. But the Enterprise are still pretty cheap and I'm wondering why. Does anyone have experience with the "RE" (Raid Enabled) or the "Gold" drives? What does the "Gold" rating mean?

The prices for these are fluctuating, I suppose because of different sources from one day to the next. But they are consistently much cheaper than the "consumer" drives. Could this because of sheer age? Are they likely to be old stocks made a very long time ago? Or is it normal for enterprise drives to be significantly cheaper than the regular desktop drives? Are there important reasons not to use an enterprise drive in a desktop? My understanding was that RE drives have a shorter 'fail' timeout of sector errors because they are expected to be in an array ('raid' of course). Is there any other possible disadvantage of these for normal users? Any thoughts or experience are appreciated.

I have always used WD Black. I think one was funky ootb and replaced. All the rest are still in service but most are not booted often.

I guess desktop drives are being replaced by ssds and nvmes today. The enterprise drives go into servers, NAS storage etc.
Anyhow: I never bought a hard drive where the manufacturer did not trust its product for 5 years warranty. WD Black and HGST did fulfill this requirement, I have several of them still around. And I wanted full warranty with easy check and direct manufacturer contact, no dealer inbetween. Fujitsu and Toshiba did not qualify for me because of this.

regarding storage media, this might be important to you
Hard drives were already bad at random access I/O—but SMR disks are worse.

Well, that tip alone makes it worthwhile to have asked for info here. According to this site:
https://nascompares.com/answer/list-of- … rives-hdd/
The drives I am looking at are CMR, not SMR. But many of those 'cheap' models, like the Red or Blue, do indeed use SMR.
My experience with WD drives in general has been good, but I always buy the high end, not the budget drives like Red or Blue. I had a set of four 1 TB RE4 drives, and still have 3 of them. One died very suddenly, but it was more than a decade old. Well past the warranty. When I moved up to 2 TB I bought the WD Black. Now I'm noticing the price difference again and I think the RE drives will be fine. Sure would like to know what the "Gold" designation means in the WD product line though. Never heard of it before finding that product.

When buying HDD's, it's common practice of experienced sys-admins to purchase from multiple vendors and restrict the amount of drives from a single manufacturer in their stripes/arrays. Recently I started buying refurbished drives from A-brands like Toshiba, HGST, Seagate and WD to name a few. So far no issues, but I don't have them powered on all the time anymore.

Like @rolfie said, ease of return just in case is best for me.
Like memory sticks IMHO, are far too big for general use, but fs (fat) is too small for large iso s and videos @ 4gb max... Not suited for purpose!
My new spinner is a Seagate Baracooder, 4Tb st4000DM004.
I'll never fill it the way I'm going.

Noise and power consumption... If those matter to you.

I really don't see how TLER is a disadvantage in any scenario. It's also adjustable in most enterprise drive firmware.
Once is happenstance. Twice is coincidence. Three times is enemy action. Four times is Official GNOME Policy.

When I had the 1TB RE4 drives, I did notice there was a bit more clatter when the drive was doing something. Not catastrophic, just noticeable while the 'consumer drives' were hard to hear even when seeking and reading/writing. This was not disturbing. What would be a problem is a constant whine when they are in operation. I wouldn't expect that from any sort of modern HD, though, since noise is wasted energy. A drive that can be heard spinning is not likely to last long.

You haven't scrolled through Amazon a bit
https://www.amazon.com/stores/page/5189 … f_=ast_bln
And the reliability of a hard drive directly depends on its cooling. I still have an ancient Samsung from that unsuccessful series that burned like candles. I just put a fan under it right away.
P.S. If you need details, you need to look at the specs on the WD website.
For example

In particular, for example, operating noise.

The data sheets I have found show the enterprise drives as only marginally louder than the consumer drives of the same size. The larger any of them get, the louder. I guess that's a predictable consequence of more platters spinning at high speed.
It looks to me that the only issue I need to think about now is whether those 'cheap' enterprise drives on Amazon are very old OEM stock, manufactured further back than their warranty technically extends. Though I've seen the warranty on the consumer drives updated when you enter the purchase date on the registration site. Maybe WD is very confident of the shelf-life of their drives? If I get a five year warranty, how much does it matter when the drive was manufactured, I wonder?

The WD Caviar Black drives larger than 1TB dropped error correction capabilities. The WD Gold drives have that and are therefore more suitable for RAID. The Gold drives a couple years ago only had a 3yr. warranty. I'm not sure about the newer ones.
The 1T Caviar Black drives I had all lasted longer than five years. (always on)
