Trying not to spend all my $ on those SSD now :) Pretty happy with Fusion-IO, but it's never enough :)

10DWPD. 67K IOPS on writing. Looks very tempting.

Pretty curious: is SM865 just SM863 with extended reserved area or a completely different drive?

Usually, they have PLP + more reserved area. Otherwise Dell and such will not sell them

Looks like somebody has stolen 3 SSDs for $400 each! Yesterday I saw this offer for $479\each and 3 available, today - for $400 but already sold out.

Have written to the seller and got mine 3 drives for $440 each. Seller told that drives were "tested by HP for 3 months only and have never been in use". Wasn't able to check warranty by HP online warranty checker though - it didn't recognize serial\product numbers.

In overall it smells a little (too cheap for such drives, price was dropped for 25% just in 1 day, the seller has found 3 more drives) but the seller has 100% reputation, was pretty active during last year and he is very good and prompt in communication, so hope everything will be ok.

I was the buyer on ebay at $400/ea - I pinged him with the offer and he lowered the price for me to buy earlier tonight. Seller refunded my purchase about 20 minutes ago without any explanation... now that I see this, it would appear that he decided to sell to you instead at the higher price.

Oh, really sorry to hear about that. I wrote him yesterday morning with an offer for $440 but asked about SMART data and label pics as well. He sent me pics but I had no enough time to check them. So I've seen listing changes just a couple hours ago, sent him a message with apologize because I didn't reply to the last his mail and asked to tell me if he will have another offer like this. But he offered me to finish our yesterday's agreement so I did.

The seller is the one out of line. He sent me a message subsequently saying that you had already had some back and forth, but once he accepted my offer and the sale went through, that should've been the end of it.

Has anyone looked at the Samsung PM963's listed on EBay? I've been tempted to buy these several times but have held off to date... haven't really been able to find much information about them. Seller claims to have 30+ in stock. Asking $350 each. If these are the real deal, they are a steal... U2 NVMe 960GB. Sellers history is positive but questionable.

Samsung SSD PM963 960GB, U.2 Solid State Drive ( use 500-700 hours)

Give me the warm fuzzy so I can get to buying...

Funny, seller wrote me with great apologies and told that the first customer involved eBay into this situation and seller was forced to break our yesterday's agreement. Seems that somebody really needs these drives. :))

P.S. Looks like I'm the only one who will loose from this situation: I paid with a national currency card and will loose on currency conversion when money will come back.

The seller doesn't have any sales during the last year. But it actually doesn't mean it's a scam. You can ask the seller to send you pics of the drive, if you want to be sure it isn't from Internet - offer him to write your name on a list and make pic with ssd on that list.
But with buyer protection you feel safe, I think. In the worst case you'll get a refund.

The only question: is this a deal? Didn't pay much attention to the NVMe drives, but if you really need NVMe and 1.3DWPD is enough for your workload then may be. But, for example, you can have SATA Intel S3610 800GB for $260 with BO. It ~30-40% slower in IOPSes, but has 3DWPD.

PM963:
960GB (120% of the S3600)
Sequential Read: 2000MBs (360% of the S3600)
Sequential Write: 1200MBs (230% of the S3600)
Random Read: 430,00t0 IOPS (500% of the s3610)
Random Write: 40,000 IOPs (140% of the s3600)
1248GB WPD


S3610:
800GB
Sequential Read: 550MBs
Sequential Write: 520MBs
Random Read: 84,000 IOPS
Random Write: 28,000 IOPs
2400GB WPD (192% of the PM963)

I suppose value would vary by use case, but to me it would appear to be a no brainer. With a chassis full of 963's, they'd get replaced with new technology long before I was able to wear them out.

Maybe Intel slaps on the high DWPD rating because they figure users won't have the patience to write 2400GB/day... :D

Whoops, my bad, confuse pm963 with pm953.

Hm... Or not. Tough day.

Actually, I recall that I just compared with random writes IOPS. For read-intensive workload pm963 will be much better. For write intensive better (for 45%; I believe that sequential writes isn't very common case) but endurance leaves a lot to desire for this case.

And about Intel: could you share what platform are you using for such a build? Very interesting.

What did I miss? Intel S2600WT2
