IBM Flash Memory Breaks 1 Million IOPS Barrier

Posted by ScuttleMonkey on from the flash-in-a-flash dept.

alphadogg writes to tell us that IBM is claiming a victory on the flash storage front. Their new research project "Quicksilver" is claiming data transfer speeds of more than 1 million input/output operations per second (IOPS). "IBM said Quicksilver is two and a half times faster than its own SAN Volume Controller coupled with IBM's DS4700 storage. It would also be two and a half times faster than technology from Texas Memory Systems, which says it has the world's fastest storage with an IOPS rate of 400,000. "

  1. Bit error rate? by Toffins · · Score: 4, Interesting

    That's very fast. I wonder how low the bit error rate is.

      More importantly, how durable is the memory?

      Doesn't flash memory have a limit on the # of accesses before it starts to fail?

      If that is true, I would hope this can help issues with SSD implementation. Sadly, I don't know as much as I should but it seems like it would help.
      Numbers aside, wouldn't speed increases like this help to establish the possibility of SSD raid configurations?

      My ignorant two cents.

  2. I'm waiting for price/performance and benchmarks by afidel · · Score: 4, Interesting

    While managing to achieve 1M IOPS is somewhat impressive, it's not hard to do for an optimal theoretical situation. Xiotech was showing 500,000+ IOPS from three of their new Emprise 5000 storage shelfs at Storage Networking World this spring, but it was all video and synthetic sequential reads. That same system would only pull about 20K IOPS on the SPC-1 real world benchmark.
