A $115 40 GB flash drive certainly gets my attention! Man, those prices are coming down faster than any of us had any right to expect.

Thanks for sharing!

David Lapadula

Great info, as always!
I'll bet non-direct costs will hasten the transition period to BEFORE the acquisition costs are equalized between the media... Things like heating/cooling savings, needing a much smaller UPS, being able to use flash RAID5 at much higher performance than disk RAID10 (and thereby needing less raw GB), applying dedupe technologies to further reduce the raw storage required for production or backup space, etc.
I'll make a guess that the transition time for when more net new SSDs are sold than FC/SAS drives is late-2012. Can't compare to all disk, if SATA is still used for high density storage.

The whole game will change for ESDs with the sub-lun FAST....



And here I was thinking when I bought my Kingston 128gb drive for ~200 about 6 months ago that was a good deal.

These ones do sound pretty sweet - Makes me want to pickup one of those mini-NAS rigs, and swap all the disks out for SSD to start to truly calculate what the max performance you can get out of those are.

This model really makes me wonder if others will adopt it in a deep IO penetration model, akin to how UCS handles the same with it's memory architecture..

I've been stopping by your blog to learn more about storage. A friend at work(Cisco) mentioned how fast his laptop runs on Windows 7 using intel x25-m gen 2 SSd. I was not a believer until I read your site and the Anandtech article.

One more thing. . . how will SSD impact storage networking? Will this drive a need for bigger fatter pipes. . FCoE over 40Gbps or 100Gbps. How does SSD change SAN architectures? Remember. . I'm new to storage. :o)

We have 11 400GB SSD drives in our CX4-960 right now testing our production CIS database, and we have seen unbelievable reduction in our batch processing time. We just ran a month-end on saturday that took 3 days on R1 15K on a DMX3 and it ran in 10 hours on R5 SSD on a CX.


What about the limited writes of such disks, ranging from 10,000 to 100,000 writes for high end SSDS?
How a V-Max deals with that limitation?
What happens when you get close the limit?


Marcos Janzen

About the 10K to 100K writes for SSDs this is an interesting article:


the "10 year limit" seems to be bulls***

Chad Sakac

PiroNet - that is absolutely NOT correct (as Marcos points out). "flash" as a product category spans a wide band.

The Enterprise SSDs we use (SLC) have individual cells that go for millions (in fact tens of millions) of read/write cycles.

In addition, the Enterprise SSDs have a larger amount of extra space - ranging from 20% to 100% more actual cells.

In the end, they have the EXACT same warranty from EMC that our FC disks do - and we don't do that lightly.

We have been selling out of them for 18 months now, and as you can see from Dave Robertson (a customer comment that I didn't solicit - but thank you Dave!) - they are being used in VERY intensive IO operations.

Long and short - "short lifespan" = FUD. Also, the degredation of performance that the early commercial SSDs (now resolved via TRIM as anandtech points out) suffered from did not affect Enterprise SSDs. This is one of those "Intel comes and visits EMC every week with the latest Flash disks and says 'we're ready now to be a second Enterprise Flashg source'" things. One day they WILL meet the spec (and we will be able to use them and STEC) and at that point, flash SSD volume will skyrocket (and prices will plummet).

Hope that helps!

hi there wow nothing touch ssd flash drives may be in say buy 2345 we would have 1300 petabyte ssd in our cellphones

Matt D Meyer

You may have seen this, but if this dude was able to get these speeds using a PC parts, imagine what EMC is going to develop in the next year or so.
