SandForce Announces Next-Gen SSDs, SF-2000 Capable of 500MB/s and 60K IOPS
by Anand Lal Shimpi on October 7, 2010 9:30 AM ESTPerformance: Welcome to the 500 Club
Let’s talk peak performance specs. I must preface this with a warning, all of the numbers you’re about to see are SandForce’s estimates and projections for how the SF-2000 series will perform. Next week you’ll see some basic functionality and performance testing but as far as I know, these numbers haven’t been reached yet. SandForce is confident that it will hit them once drives start shipping, but until then take what you are about to see with a grain of salt.
Random read and write performance goes up significantly over the SF-1200/1500. We are at 40K IOPS today, and SandForce is promising 60K IOPS with the SF-2000. Note that this is not only higher than anything shipping today, it’s even higher than what we recently found out about Intel’s 3rd generation X25-M/X25-E SSDs.
Now the shocker. Thanks to 6Gbps and ONFI 2/Toggle support, the SF-2000 will support up to 500MB/s sequential read and write speeds. On an 8 channel device that’s actually only 62.5MB/s per channel but the combined bandwidth is just ridiculous for a single drive. At full speed you could copy 1GB of data from a SF-2000 drive to another SF-2000 drive in 2 seconds. If SandForce can actually deliver this sort of performance I will be blown away.
Let’s talk about reality for a second. SandForce quotes standard iometer numbers, which are usually quite optimistic for SandForce's controllers. I’d expect real world performance to be a bit below these figures but not by a lot for many workloads.
In the SF-1200/1500 series, SandForce used enterprise features to differentiate the two controllers. You got some improved reliability and a giant capacitor with the SF-1500 designs, but you didn’t really get any added performance. With the SF-2000 series, we will see more differentiation between the enterprise and consumer parts. SandForce indicated that the consumer version of the SF-2000 would have a different level of performance. I get the impression that the specifics of the consumer drive haven’t been determined yet. I’ve already started campaigning to see a full spec version in the consumer market but it’s still far too early to tell what will be shipped. If the 3rd generation X25-M is really only capable of 270MB/s reads and 170MB/s writes, I’m not sure if there will be the motivation to deliver a 500/500MBps part into the enthusiast market.

Intel will be slower, but I bet it will be more reliable.Intel will also be able to offer twice the storage for the same amount 22nm vs 32 nm.
So high stable performance and twice the area, vs fast and small. So far all of this is vaporware.

I wouldn't call the Intel product vaporware. It's almost guaranteed that they'll ship them on time.ggathagan - Friday, October 8, 2010 - link
I believe ibudic1 was referring to the Sandforce controller as vaporware, not Intel's product.sbrown23 - Thursday, October 7, 2010 - link
You mean 25nm vs 34nm? And Intel products are generally not vaporware. They have a fairly good record of delivery. This isn't Duke Nukem Forever, here.anindividual - Thursday, October 7, 2010 - link
http://www.plianttechnology.com/They have had an enterprise drive line with a proprietary controller on the market for over a year with much of this capability.

That link indicates that the company in question is using SLC flash in their drives. This is guaranteed to put them out of the same price range as the Intel and Sandforce MLC drives, the latter already being expensive enough to be seriously limited in their market uptake. Conclusion: almost nobody is buying the Pliant Technology drives because they are too expensive compared to other options.mino - Thursday, October 7, 2010 - link
Nobody is willing to go for MLC in REAL enterprise drives.X25-E and the Sandforce stuff is mostly good for HPC and lower mid-range, but mostly DAS setups.
The EMC's of this world use far more robust (and far more pricey) solutions.

"""X25-E and the Sandforce stuff is mostly good for HPC and lower mid-range, but mostly DAS setups."""X25-E is an SLC drive. The X25-M is MLC.
"""Nobody is willing to go for MLC in REAL enterprise drives."""
You'll find that vendors are not targeting MLC at enterprises, but rather eMLC, which is somewhat different.
And you'd be wrong about enterprises wanting to avoid eMLC drives. They (will) serve pretty well for many work loads, in places where SLC is cost prohibitive, and spinning disks are too slow.

"Nobody is willing to go for MLC in REAL enterprise drives" ????I work for HP in the Server division and all I can legally tell you is your WRONG.
PS: Ever heard of a slow little drive called the ioDrive Duo? The 640GB model uses MLC. I recently sold 3 of these to a Global 100 company that plans to run a SQL based Data Mining app on them.

Pliant "LB 150S" = 150GB (2.5" + SLC + SAS dual port ) for $4500 !@anindividual : please ask your boss to review the price, this is just non-sense !
