SSD benchmark

Vendor: INTEL     Model: SSDSA2M080        Rev: 2CV1
Type:   Direct-Access                      ANSI SCSI revision: 05
  • Filesystem xfs mounted –nobarrier
  • Block size 16KB
  • OS: CentOS 5.4
  • Description of setup.
    1. In first runs (software) each card connected as individual card to Adaptec, so in OS we see 8 individual cards. Card configured in software RAIDs: RAID0, RAID10, RAID5, RAID50
    2. In second round (marked as hardware) each Adaptec is configured as hardware RAID0 over 4 cards, so in OS we see 2 devices. Devices connected in software RAIDs: RAID0 and RAID10 with different OS schedules over each device.

Summary results (in MB/sec, more is better):

  • rndrd - random read, rndwr - random write, rndrw - random read/write, seqrd - seq reads, seqwr - seq writes
