Texas Memory System’s RamSan-440 reportedly sustains a record 600,000 IOPS and quadruples capacity for RAM-based solid state disks.

SanDisk, Seagate Technology, Western Digital, Samsung, Toshiba and Fujitsu have been making most of the solid-state disk headlines lately. They now have some company from an old, familiar face.

The RamSan-440 is the world's first non-volatile RAM-based SSD to sustain up to 600,000 IOPS (input/outputs per second) and deliver up to 512GB of storage capacity in a 4U rack-mount chassis, the Houston-based company claims.
