Hello,
I am looking to add a Highpoint Rocket 1608A to my NAS, but I am not sure which M.2 SSDs I should choose.
I would like to use 8TB drives, but the ones featuring PLP (Power Loss Protection) are not compatible with this card; I have only been able to find consumer drives so far.
Any drive recommendations for an 8TB setup with this card? (PCIe version doesn’t matter)
Thank you all!
Kind regards
Why PLP?
If this feature is relevant for you, look at enterprise U.2 drives rather than consumer M.2—especially for capacity.
Thank you for your reply.
Honestly, I mentioned PLP because reliable SSDs usually have it, but I could be wrong about that.
What is most important is having decently high endurance and proof that they won’t die after 200–300 scrubs of, say, 6/7TB per SSD. What I need most is for the array on that card to stay alive for at least five years, though longer would be even better.
The intended environment for this setup is a TN server with 1 or 2 of these cars filled with identical ssds, and will support 2x 25 GbE links, about 10 VMs for services, and another 15 VMs as VDIs for workstations.
I am considering a raidz2 on each card and a pool built out of the 2 cards.
I found some WD Black SN850x 8T at a price of 500$, which is steal considering the market, but I am afarid that this SSD will not be reliable and might die after 1-2 years of use.
That’s only correct if you equate “reliable” with “data centre-grade”.
Write endurance?
Scrub is mostly read (hopefully exclusively read…), so PLP is irrelevant.
Raidz2 is inefficient with small writes. While SSDs may have enough IOPS to cope with block storage on raidz, you should rather consider mirrors.
And put this very professional server on DC U.2/U.3 drives.
The best indicator would be that the manufacturer offers a warranty that is longer than that…
But PLP? No.
Well, I think it should be as robust as possible since I am storing my data on it, though I might be wrong.
It also needs to be durable enough to stay powered on for months at a time
Will do some testing.
I have an array of U.2/U.3 drives, but I want to keep that as a ‘safe’ array for backups. I’d like to use these [M.2] drives first to save wear on the U.2/U.3 units, since the M.2s are less expensive, and then back them up to the U.2/U.3 array.
Understood, thank you!
I’ve also considered the Liqid Element LQD4500 (Honey Badger). It looks like it could fit the long NVMe drives and might be more reliable, but I’m not sure yet—I wonder if it will overheat.
Do you have any suggestions for 2280 SSDs?
Thank you very much!
Huh… what’s that got to do with PLP?
PLP is being able to handle gracefully that power is being cut off: This is a matter of milliseconds, and then it’s over.
IMHO that’s totally backwards: Put the actual load on the DC-grade U.2, and the less demanding backup on M.2 (could well be HDDs).
In this market: Whatever you can get!
