Haha. Soon it'll be back to 52.99

Update:
Using a SM SYS-1028U-TNRT+, the drives show up. This is a SAS3 backplane w expander

 

[itronin]

Its possible. I think its more likely old new stock or field service spares that have been auctioned off. In my 21 drive order, the loose drive was manufactured March 2017, the other 20 drives came in a manufacturer sealed box and included silica gel packs in each drive's sealed anti-static bag. To me that says new, old new stock, manufacturer refurb. I could find no physical signs of wear or installation of the drives, no scratches, no thread use etc. etc.

I too think the drives are awesome. Whether 53, 55, or even 60 dollars. very pleased with this deal. I'm hopeful these drives are like timex watches.

Are you able to share any disk benchmarks using 12 gbps SAS? I would love to see CrystalDiskMark results for a single drive if possible.

I ran a quick and dirty test with 4 in RAID 10 on my new Quanta D51B-1u (from another hot deal here). It has a 12Gbps backplane hooked up to a 12G lsi card. running

dd if=/dev/zero of=/test.data bs=1M count =80000

to generate a file larger than memory, I got ~1.4GBps. Reading back off was a little worse,

dd if=/test.dat of=/dev/null bs=1M

yielded ~680MBps.

Not super scientific, and the machine WAS under very light usage, but that might give you a data point. Again, 4 drives in RAID10 WRITE THROUGH /NO READ AHEAD caching.

Any reason for RAID10 on SSDs? Isn't RAID5 the preferred mode?

 

[josh]

Having worked for a storage company for a few years, it depends. If you care about size, raid 5 is better. With SSD URE rate (10 in 10^17, or something like that), your chance of an error during rebuild is lower. However, you still have to pound all remaining SSDs to rebuild the missing drive, and both at my previous company (cloud storage) and my current company (network/cloud security), I have seen more than my fair share of SSD based RAID5 arrays suffer dual or even triple drive failures. Now, I'll admit the current company was doing 24 drive raid 5 with no hotspares, so that's even worse, but I wouldn't risk it. Raid 10 is faster (again negligible with these ssds) bit only rebuilds from one drive not all. And it rebuilds faster due to no parity calculations.

*Forgive grammar and spelling, writing on cell phone

But were they using these HGST models which have supposedly much higher endurance ratings? I'd love to hear about how those companies recovered from 24 drive RAID5 failures. RAID10 seems like a bigger risk if you're storing data across multiple RAID10 sets no? I guess your drive count is too small for RAID6.

64.99 BTW now.. was just about to buy a few more.

smart for the seller. Nothing wrong with making a few more dollars. Qty is down to 10 unless the seller is holding some back. I'll update the title and OP.

 

[josh]

Hey guys, I acquired more of these drives from another seller but the writes seem a little high, between 80-300TB and power on hours around 1.4k. Should I get more or wait for fresher drives?

 

[T_Minus]

80-300TB isn't much, and 1400HRS is also not much.
Be glad it's not 20,000 Hours and 500TB I still run those though, they last for petabytes

 

[josh]

Is there some software to do an extensive test? Does surface tests mean anything for SSDs?

 

[Samir]

Does surface tests mean anything for SSDs?

It still kinda does as it's going to stress the sectors in the same manner as it did for hard drives, but dedicated ssd tools are much better for testing ssds.

How does the latency on these 12 GB SAS drives compare to Intel S3700?

Stumbled across a listing for Sun branded drives that might be the same for $47.95 OBO, 30 available.
I submitted an offer for 8 @ $37.5 each and it was accepted, which I think is a steal if they are indeed HUSMM 400 GB drives and aren't locked down somehow.

Really excellent find. If I find I need to sell some of mine looks like there is a new price to beat

Thread title updated. OP updated with link to this deal and notes by @int0x2e.

 

[itronin]

I'm curious about this. Drive Tray picture number 2 on the seller's listing says "SATA 400GB". I'm not aware of any HGST HUSMM1600 variant that is SATA. MFG sticker on the drive has the SAS LOGO on it though. IDK.

I tried 37.50 for 10 and seller declined

Based on the part # it's SAS3 and they state SAS3, so I'd believe that vs. what a tray states.

I've never run this branded one only HPE.

 

[frogtech]

Tried to get 25...too many offers ahead of mine though I guess. STH effect.

 

[josh]

Tbh this is a pretty bad deal even at 35. I've gotten these for under 30 a piece on /r/homelabsales. Luckily the seller declined.
