Intel 910 series SSD


Intel today finally announced their SSD 910 "Ramsdale" PCI-Express SSD family. This is Intel's first SSD in the form of a PCI-Express add-on card. Like its 2.5" SSD 710 series, the SSD 910 utilizes HET-MLC NAND flash chips, arranged in four SSD subuits. SSD 910 design consists of three stacked PCBs, the one with the PCI-Express 2.0 x8 bus interface holds a PCI-Express to SAS bridge (essentially a RAID controller), and four SAS/NAND ASICs (SSD controllers). Each controller is wired out to its NAND flash memory chips, which are arranged in the other PCBs. The PCIe-SAS bridge is made by LSI. The SSD 910 series comes in two variants based on capacity which are 400 GB and 800 GB. The 400 GB version has just two SSD subunits, and hence provides transfer rates (according to an older article) of 1 GB/s reads and 750 MB/s writes, with 90,000 IOPS reads, with 38,000 IOPS writes; while the 800 GB variant, with its four subunits, provides 2 GB/s reads with 1 GB/s writes, and 180,000 IOPS reads, with 75,000 IOPS writes. The launch price of the SSD 910 400 GB variant is US $1,929; while the 800 GB variant is priced at US $3859, at launch.
