Next-gen SandForce SSDs to support 6Gbps SATA

Sandforce has fresh SSD silicon in the works. Dubbed the SF-2000, the new controller promises broader NAND compatibility and faster performance. AnandTech has all the gory details.

Although Intel has yet to commit to offering next-gen SATA support in its upcoming X25-M refresh, the SF-2000 is ready for 6GBps SATA. Indeed, the controller needs the faster interface, at least to make the most of its potential. SandForce claims the SF-2000 is capable of sustaining read and write speeds of 500MB/s, which is considerably faster than what an old-school 3Gbps SATA link can handle. Performance with random reads and writes has been improved, as well. The SF-2000 can purportedly crunch 60,000 IOps with 4KB random reads and writes—twice the throughput of the old SF-1500.

Thanks to support for all kinds of NAND, we could see SSDs based on the SF-2000 at a variety of price points and performance levels. The chip supports the faster ONFI 2.0 flash that's already seen action in Crucial's RealSSD C300, and it's equipped to make the most of "toggle mode" NAND developed by Toshiba. With the low write amplification factor inherent to SandForce's DuraWrite technology, the SF-2000 should also be a viable option for drive makers looking to put together budget SSDs based on lower-grade flash chips with less write-erase endurance.

Solid-state disks based on the SF-2000 aren't expected to hit the market until the first quarter of next year. I suspect we'll see quite a few of them on display at the Consumer Electronics Show in January.
