Intel collaborates with Hitachi on Ultrastar SSD400S solid-state disk
Intel and Hitachi have collaborated on a new line of enterprise-class solid-state disks. Today marks the introduction of the Ultrastar SSD400S family, which will be available in 6Gbps Serial Attached SCSI (SAS) and Fibre Channel flavors. The latter will live inside a 3.5" form factor, while the former can squeeze into a smaller 2.5" casing.
With only 4GBps of interface bandwidth at its disposal, the Fibre Channel model's performance is capped at 390MB/s for sequential reads and only 340MB/s for writes. Using the term "only" to describe those speeds might seem a little odd, but the SAS version is said to be capable of hitting a whopping 535MB/s with sequential reads and 500MB/s with writes. Impressive. Things don't look quite as rosy for random reads and writes, which top out at 46,000 and 13,000 IOps, respectively. Those figures are a little low considering that Crucial's RealSSD C300 is rated for 60,000 random-write IOps and 45,000 random writes. SandForce's SF-1500 controller can purportedly push 30,000 IOps with random reads or writes.
