Several PCI Express SSDs are on display at CES this week, including an Adata drive powered by the SandForce "Griffin" controller, otherwise known as the SF3700. The controller has a four-lane PCIe 2.0 interface and supports the NVM Express protocol. Adata's server-oriented SR1020NP SSD puts the chip on an M.2 2280 gumstick with up to 2TB of flash.
If this all sounds familiar, it's because the same drive popped up at Computex last June. Adata tells us that pricing and availability are still to be determined, though. Hopefully the drive makes it out before this year's Computex show.
Adata is also showing off a new budget SSD dubbed the SP320. This 2.5" SATA drive employs a Silicon Motion SM2256 with quad NAND channels. We don't have details on the flash provider, but the drive uses TLC NAND with three bits per cell. It will be available in the first half of the year in capacities up to 960GB.
As we saw with Adata's SP610, four-channel SSDs are capable of keeping up with more traditional eight-channel designs. I'm curious to see how the SP320 fares with TLC NAND—and how affordable it will be. The MLC-based SP610 is available for $0.41-0.51/GB right now.
