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 ESTFinal Words
SandForce conveyed to me that although we may see hardware this year, production firmware and silicon won’t be ready until early Q1. Anything that ships before then is not what SandForce considers production worthy. This is an important distinction as SandForce’s partners often ship with pre-release hardware/firmware in order to gain traction and sales as quickly as possible. We’ll probably see less of this as SandForce matures as a company.
The specs behind the SF-2000 are downright amazing. If SandForce can deliver this sort of performance within two quarters I will be floored. If we’re talking about 500MB/s for a single drive next year, the sort of performance you’ll be able to get through a multi-drive array will be staggering. We’re easily heading towards gigabytes per second of affordable I/O bandwidth, not to mention that SandForce will have nearly maxed out 6Gbps SATA on its first attempt.
We will of course see drives from the usual suspects. OCZ, Corsair and even Seagate is now officially listed as a SandForce customer. Looks like those Pulsar rumors were true.
There’s still a long way to go before we’re at the point where we have a shipping SF-2xxx based drive with these specs however. If you remember the growing pains that Intel, Indilinx, Micron and SandForce all experienced with this current generation of controllers, I don’t expect the next round to be any easier.
SandForce is serious however. The company only has 88 employees but it just closed another round of funding ($25M Series D), bringing the total funding to $67M. The company is headed for an IPO. And if it can pull off the SF-2000 we saw on paper today, SandForce may have the sales to support it.

You know what else comes out in Early 2011?Sandy Bridge and the Intel 60 series chipsets.
Intel has already announced they will have 2 SATA 6Gbps ports on those chipsets.
Core i7 2620M with 8GB of DDR3 and a SATA6G SSD? Yes Please!
Stick a 750GB Green SATA Drive where the Optical drive usually goes and then just use a $40 USB DVD Drive when you really need it (rarely now that DVDs include the "digital copy" and software companies are embracing online delivery.
And of course throw in an nVidia Optimus 4xx as well.

So we have a battle of Specs ? Sure makes the Marketer's jobs easierjwilliams4200 - Thursday, October 7, 2010 - link
In a battle of specs, I am going to trust Intel a lot, and Sandforce not at all.The most careful SSD reviews these days are coming from bit-tech.net. They use AS-SSD to test sequential write speed for incompressible data, and also they fill the drive up with data, delete it, run TRIM, and then test the drive again.
http://www.bit-tech.net/hardware/storage/2010/09/0...
Check out the lighter-colored bars on the sequential write speeds. Those are the speeds after writing a lot to the drives and then TRIM. Note that the Intel X25-M 160GB gets 99 MB/s sequential write even after being heavily used. It is spec'ed at 100 MB/s sequential write. Just as Intel specified, so their SSD performs.
Next, look at the Sandforce drives lighter-bar sequential write, for example, the OCZ Vertex 2E 120GB. This is a drive that is spec'ed at 275 MB/s sequential write. But when someone actually measures the speed with realistic data, after the drive has been used, it only manages a pathetic 83 MB/s sequential write. That is only 30.2% of the spec'ed value, and is even lower than Intel's 99 MB/s !
Or look at the Revodrive, which is two SF drives in parallel with a RAID controller. It is spec'ed at 490 MB/s sequential write, which looks quite similar to what Sandforce is claiming for the SF2000 series. But what is the actual, real world sequential write for the Revodrive? bit-tech.net measured it, and it is a pathetic 139 MB/s. A single Crucial C300 256GB drive achieves 190 MB/s !
Bottom line is that none of Sandforce's specifications can be believed.

Just wanted to tell you, that the german site computerbase.de came to the same conclusion. They even had a talk with OCZ about it and they admitted it: the sandforce drives lose performance after being heavily used which cannot be restored with TRIM, only with a secure erase.Sequential write on random data dropped from 140MB/s (fresh) to 90MB/s (used) on a Vertex 2 120GB.
Real world usage was still pretty good though.
Zan Lynx - Friday, October 8, 2010 - link
Agreed about real world usage.You have to benchmark the drives with an application you're actually using. If you only write encrypted data that looks random, then do not buy a Sandforce.
On the other hand, if you use real programs the data will not be random and the Sandforce will perform well.

They use incompressable data for what you linked. That's not realistic. That's worst case scenario, which is unlikely to happen. I believe anand did a set of similar tests and got a low speed too. SF's speed relies heavily on compressing data.hackztor - Thursday, October 7, 2010 - link
they never mentioned price. All is cool for 1gb in 2 seconds, but if the price is 1000, I think many consumers will have a hard time justifying this.Phynaz - Thursday, October 7, 2010 - link
It's not a consumer device.Chloiber - Thursday, October 7, 2010 - link

I suspect that SandForce worker force is out of this world. I think the slides that we just witnessed today confirm that indeed Aliens have come to this planet and are working for SandDorce. How else would you explain such amazing performance on very new technology in so short time?I call all UFO hunters and Aliens investigators to go to SandForce HQ and investigate, ladies and gentlemen this way be the most historic day in the history of planet earth by uncovering aliens working for a human firm.
