.I think I can live with that as long as it's cheap & reliable
.My very limited understanding is that 1 bad sector isn't a big deal. The price is concerning though. Makes me think the seller knows something they aren't letting on, either that or it's a great deal right?
Usually once the first bad sector appears more are on the way. These enterprise drives should have enough buffer cells to reallocate so that means it's burned through all of it? (Don't quote me on this)
Oh I see, so having a bad sector means it's already had enough reallocated sectors to burn through the extras. Hard pass then.
Not necessarily, if the sector fails to read the drive has to report it so that raid controllers or software can do the right thing, but then a future write would go to a fresh page of NAND from the reserve and work fine. It's sort of impossible to tell exactly what the seller means without the full stats from a drive.
As far as I know SSD controllers don't parse the partition table at all, so unless you're using NVMe namespaces to over-provision you just want some region that won't ever take writes from the host. I don't think that really gains you much on an enterprise drive unless you're trying to get better sustained random write performance out of a 'read intensive' type drive.
I have a pair of boxes doing SAN duty...just two boxes with no clustering. They have been running 5 years straight with only planned downtime.
I couldn't do it without the whole-house generator that kicks in after 30 seconds, but even a hard crash of the SAN isn't that big of a deal...I had a few before I had continous power. Sure, the VMs lose what they were doing, but it's no different from just pulling the plug on a physical box. Once the SAN comes back up, the VMs can be started and fsck/chkdsk run if necessary.
That probably rules out most NVMe Drives, surely U.2 and PCIe, leaving possible M.2 up to the Game (assuming they will do ASPM).Thanks. That answers the question nicely! My dream of low power AND (relatively) low price in a 3+ TB drive remains unfulfilled.
Personally I don't mind a bit of power draw, but achieving domestic bliss and WAF require me to my "computer junk" (wife and kid's term) in my home office. So, I'm trying to avoid stuff that requires too much active heat dissipation.
So you are left with SATA and SAS, out of which SATA is much better in Terms of Power Consumption, but also quite a bit more expensive in the 2nd Hand Market (around twice the Price as SAS/NVMe ?).
I don't necessarily think it is the case. I have an Intel P5510 3.84TB that I bought on ebay with 14,389 uncorrectable error count (I presume that's what they mean by bad blocks, unless they mean reallocated sector count). But smartctl shows 100% available spare. And that error count has been steady, even though I have been punishing it.
I have a few more used SSDs with either reallocated sector count or uncorrectable error count, but all have been stable. I am not sure that it is comparable to a HDD where often bad blocks means that there is something has gone physically wrong and you are likely to see more popping up.
But in the end, if you go bargain hunting on ebay for SSDs, I don't think you should assume you are buying drives "as good as new". My approach is that it is a way to buy many for dirt cheap, to build large arrays, and to have redundancy to deal with problems. If you critically rely on a single SSD to never fail, then I don't think that sourcing them that way is very wise. That's the pet vs cattle analogy.
Hi, everyone I cam here to find some deals on ssd's, but most good deals get sold out quickly (naturally). I can find a lot of extremley good prices which are too good to be true, like this 6.4 tb SSD for $20;
Does it mean there are a lot of scammers on ebay, and how do you distinguish them from the sellers whose items are posted here?

That's actually quite a good Deal on 6.4TB.
I paid approx. 100 USD / Piece for 3.2 - 4.0 TB NVMe Drives lately (if you exclude the P4608 6.4TB that I got for around 142 EUR / Piece including VAT & Shipping), so it seems to scale up quite nicely
.That’s an auction. The price will go up as people bid. Auctions are rarely good deals. But lots of counterfeit/fake retail SSD on ebay, not so much in the enterprise space.
Please be careful though, some of the Links I posted previously are for SX300, one (at least) was for SX350. We shouldn't throw them all in the same Class, as the SX350 seems to have much better Performance.
EDIT 1: It seems the 6.4TB SX350 is ONLY available in Low Profile Version
That's kind of a Bummer for those looking to install these in a 2U Chassis .
Perfectly fine in a Desktop Chassis though with some Fan cooling it from the Side I would say though, as @nexox said.

Hi Gramosa,
That is an auction so it might end up being $400 (as example), there is 7days to go, so who knows what it will actually be. If you bid and win for $100 then it could be a good deal…
wish I could get some of these deals too, hard being in Aus and the timezone difference means most are gone by the time I wake up.

Sorry, I might have taken a bad example I saw many buy-it now items like this:
Its a 4tb m2 for $39
Or this 2TB SSD 2.5" for €89 (which might not be such a good deal btw):

First one is almost certainly fake (fake capacity). Lots on ebay, imitating the look of samsung and WD drives, but without the brand. And you get maybe 100GB of slow storage inside if you are lucky (but will look to the system like if it was multi-TB), and the device bricks itself if you write a byte more.
It does almost come back full circle tho.
If its a legitimate drive with that size its likely to be made by Samsung originally.
Sorry, I meant that it's only available in HIGH Profile Version (the 6.4 TB Variant).
You CANNOT buy it in Low Profile Version, you'd have to chop half the Card up if you wanted to install it in a 2U Chassis (Low Profile only) and at that Point it wouldn't work anymore.

IIRC, Oracle and Cisco lock down hard for what you can put in their boxes, but the actual components work fine anywhere else. As for firmware updates, etc., those are likely hard to find.
