Seagate Technology has introduced two, 2.5-inch solid-state drives for the corporate data center.
The Pulsar XT.2, which supports a 6 Gb/s SAS bus and has a maximum capacity of 400 GB, is the fastest drive in the Seagate portfolio, with sustainable random reads at 48,000 and writes at 22,000 input/output operations per second (IOPS). Sequential reads are 360 MB per second and writes are at 300 MB/s.
The Pulsar.2 has a maximum capacity of 800 GB, supports both 6 Gb per second SAS and SATA interfaces, and comprises multi-level cell NAND flash, which gives it twice the capacity of the single-level cell XT.2. MLC SSDs are just starting to be deployed within data centers for running applications that need faster performance than what's available from traditional hard-disk drives.
