RAID1 RAID5 RAID10 speed comparisons using SATA drives

Using a Gigabyte onboard RAID controller I compared RAID1, RAID5 and RAID10 arrays using 500Gb Seagate SATA drives

Standalone the drives provide about 100Mb/s read and write speed.

RAID1: 2 x mirrored drives

  • Read = 100Mb/s
  • Write = 100Mb/s

RAID5: 4 x striped drives

  • Read = 300Mb/s
  • Write = 80Mb/s

RAID10: 4 x striped & mirrored drives

  • Read = 220Mb/s
  • Write = 220Mb/s
