OWC Mercury Accelsior PCIe SSD card

This page details the performance across the entire drive capacity (0..1000 files) using the DiskTester fill-volume test.

Three OWC Mercury Accelsior PCIe SSDs were used: one 240GB model and two 480GB models (mixing capacities is not recommended, this is simply a test “for fun” using available hardware).

RAID-0 stripe

Consistent speed is seen for both compressible and incompressible data across the entire drive, with the speed of incompressible writes dropping to “only” 1000 MB/sec! It would require 8-10 fast hard drives striped to reach that speed.

Curiously, incompressible data reads at notably faster speeds than compressible data, hitting over 1800 MB/sec!

Readers should be clear that this extreme level of performance is of no practical use for any software that we’ve ever used here at MacPerformanceGuide.com.
