IBM tested 4 terabyte (flash memory) solid-state drives
It's feasible that we could get it commercialized within 12 months," said Charlie Andrews, director of product marketing for IBM systems storage. "Right now we have a screaming (fast) system, but there's more work to be done in terms of long-term reliability and integration with systems applications. We don't want to get distracted with 'push the hardware.' We want to focus on the solution piece first," he said.
IBM coupled solid-state drives with its storage virtualization technology to achieve a sustained data transfer rate of more than 1 million input/output per second (IOPS), with a response time of less than one millisecond in a 4.1-terabyte rack of SSD storage. SSDs are being supplied by Fusion-io.
By comparison, Intel is commercially shipping SSDs (X25-E Extreme) that individually achieve random data reads of 35,000 IOPS and random writes of 3,300 IOPS. In a 3.8-terabyte storage array using 120 SSDs, Intel claims 4.2 million IOPS.
