Performance of 'Fusion' Drive (OWC Accelsior 480GB PCIe SSD + 2TB HDD)

After setting up the Fusion drive (480GB OWC Accelsior PCIe SSD + 2TB hard drive), I tested it by writing 256GB of files to it.

The OWC Accelsior PCIe SSD looks like an IDEAL choice for making a Fusion drive. It can be used in a Mac Pro PCIe slot, or with any Mac having Thunderbolt by installing it into a OWC Helios external case.

UPDATE: careful testing shows ZERO benefit either with the Accelsior PCIe SSD or with a SATA SSD (these are both non-Apple configs, no comment here on Apple’s official setup). All that is seen with non-Apple SSD+HDD fused drives so far is simple, dumb JBOD behavior: SSD fills up, overflows to hard drive, thereafter speeds are hard drive speeds, no migration of files occurs.

Testing was on a Mac Pro. Could it be that the feature has certain requirements?

  • Perhaps it has to be the latest chipset from Intel?
  • Perhaps the SSD has to be on a SATA III port (Mac Pro is only SATA II).
  • Is the version of 'diskutil' used different than that shipped with Fusion-enabled Macs? (the version from 10.8.2 was used for testing).

Researching— a 2012 MacMini will arrive tomorrow.
