Performance for the Seagate SandForce SF3500 Controllers Leak Out of Computex

Some new information concerning Seagate's SandForce SF3000 series of controllers for solid state drives. Seagate is showing off the controller during Computex, but won't reveal full details on its performance until later in August. However, this leak provides us the nitty gritty, and boy does it look good. The SF3700 parts will be used in enterprise SSDs and pack in some enterprise-level features, but the four-channel SF3500 parts are for consumers. The SF3514 is the mainstream SATA part, the SF3504 the entry-level PCIe, and the SF3524 the enthusiast level for boh SATA and PCIe. The SF3514 can hit read speeds up to 550MB/s and write speeds up to 450MB/s, but both the SF3504 and SF3524 can hit read speeds up 900MB/s and write speeds of 525MB/s. Random read on the SF3514 is 100,000 IOPS, with random write at 80,000 IOPS. The SF3504 and SF3524 both have a random read of 130,000 IOPS and a random write of 90,000 IOPS.

All three controllers support a maximum capacity of 1TB; support MLC, TLC, and 3D flash; and support dual AES-256 encryption. The two PCIe models are on the PCIe 2.0 x2 slot and not the x4 slot like some other recent controllers, but that usually doesn't hinder a SandForce controller much. Still, real world tests will show all of that and more, just we won't get to know for sure until later this year.
