SSD Write Endurance 25nm Vs 34nm

[Christopher]

think of what the 710 could really do...jesus 30X (projected) of the results we have seen with the 320 would be simply insane...not to mention that the 320 is still running.



very thought provoking that they could achieve this type of performance/endurance with no over-provisioning dedicated to spare area, only as XOR.

also no mention of 25nm SLC anywhere even this "late" in the 25nm game...

Also at the same site, in a different article, is a discussion of Larsson Creek's successor which utilizes 25nm SLC.

Ask and ye shall receive (some random PowerPoint slides from IDC).


What I found funny about the HET-MLC article was actually the fact that Intel states the write span of a 300GB 320 as only 30TB -- only 100 times it's capacity. That's like saying an X25-V can only write 4TB over it's life span. Talk about under-promising and over-delivering.

I can't wait to tear into this Mushkin. I'm not sure what SF does with 32nm toggle nand as far as sacrificing one whole die... I thought they were doing something different for the 60GB capacities. Maybe RAISE isn't enabled for the 60GBs? If it works as well as Intel's system (and is enabled on the Chronos Deluxe 60, then it could last...... a lot further than this "premium Toshiba Toggle NAND's" PE cycles would indicate. Not to mention, if your workload is at all dedupe friendly, you get sub 1 WA.

The Chronos Deluxe will be my first SandForce drive (all of my drives are Intel, Indilinx, or Micron controlled), but honestly, I'm pretty impressed with the new Vertex Turbo that came while I was away. I played with it today and it's pretty damn fast for a two year old drive with 50nm Samsung NAND, but the SF2281 controller could be a whole other level, even on the Intel 510, in terms of both performance and longevity with 32nm flash. It's assembled in the USA like OWC's Mercury Pro's. I've already set up my desktop for silent running and ran ASU on one of the Agilities for 8hs in preparation.
I can't wait.
