Got 4 of these from him a few weeks back @ $250 each. Phenomenal devices!

If I had another spare 1K sitting arnd, I'd snag 4 more :-D

@whitey, curious what are you using them for? I'm planning on using them for VMware VM storage.

@whitey, curious what are you using them for? I'm planning on using them for VMware VM storage.

That is exactly what I use them for. 4 husmm1640's for main pool, 4 husmm1680's for replication pool (expensive rep pool I know lol).

Just curious are they in raid10 and what controler you are using ?

 

[azev]

man, I seem to always missed great deal such as these

 

[whitey]

Raid0 of course lol, I was testing pure perfbut yeah they need to go at least back to a raidz or raid10, w ssd's I've recently having internal struggles go justify raid10 on my afa pools much as forever I professed that as gold...hence the replication pool shooti g data syncs over twice daily.

Was it fully compatible with this ssd ? I see in the description it says dell emc and I was wondering about locked firmware issues which dell branded drives usualy have ?

 

[whitey]

No issues for me after sg_format, I think I even created a pool w/out doing that and no issues, sg_format by habit almost now on sas devices

I don't know much about the command, i use intel ssd so far (SATA)and for ssd i only do "secure erase" or firmware update with intel toolbox ,no reason to format flash drive.

Were you able to read smart data of the drive and flash with new hgst firmware if needed
?

 

[Evan]

Don't know those exact ssd but the enterprise ones I have looked at at 1x10 power 17 for ure and in theory very high mtbf so for anything that's not super high availability (and then you would not be buying off eBay) the the single copy and replication seems to be a perfect valid way to handle it.

Has anybody seen failures of these high end drives ?

 

[T_Minus]

These drives use Intel NAND as their build states and HD Sentinel, with that said I'd expect to see failure rates similar to other Intel enterprise SSD.

 

[SlickNetAaron]

Awesome deal! Wish I could justify these.

Interesting... Are these SSD800GB or SSD1600MM?! they say both. Picture says 1600.

 

[T_Minus]

SSD1600MM and SSD800MM and SSD400MM are the madel of the SSD.

They can have capacity 200, 400, 800, 1.6TB, etc... but the 1600, 800, 400 are the generation of the HGST SAS drive.
800 = SAS3
1600 = 2nd Gen SAS3
400 = SAS2 (maybe gen 2, i forget now)

 

[dicecca112]

@whitey What cables are you using?
@SlickNetAaron it was a great deal. He jacked the prices up unfortunately, I would have liked 4 total. I went with intel 3710s instead. I had been looking for months for deals on these.

minisas-HD 8643 (off sas3 HBA) to minisas 8087 (to backplane) in a sc216 chassis w/ A-type backplane.

I spent way too much time trying to decipher the HGST naming scheme, and never did find the answer to the generational issue. Thanks for solving one of the mysteries of the day!

The 200 ... 16000 should be the "full initial capacity" of the device. The "A" is the generation of device.

It's the same as in their model number: HUSMM1680ASS200

H ... HGST
U ... Ultrastar
S ... Standard
MM ... multi level cells
16 ... full initial capacity
80 ... capacity of this device
A ... generation of device
S ... small form factor
S2 ... SAS 12 GBit (S6 is 6 GBit)
0 ... don't know
0 ... encryption capability​

IIRC I've seen this on Ultrastar Datasheets.
