Fragmentation over time and TRIM
Fragmentation Over

Due to the SiImage chip not playing nicely with HDTach, I had to resort to HDTune to evaluate performance after the Revo was tortured by our battery of benches:

As an interesting data point, here’s the ioXtreme Pro‘s results:

TRIM:
RevoDrive does not support TRIM as the on-board SiImage RAID controller is incapable of passing those commands onto the SandForce controllers. The big advantage of SandForce controlled flash is its excellent handling of fragmentation. Without TRIM at play, these chips can still maintain full write speeds after the most challenging write patterns have taken place.
ioDrive’s do not yet appear to support TRIM, but it would be an easy addition through an update to the firmware and/or driver. After seeing that they do in fact fragment (and take a fairly large percentage hit on write speeds in the process), hopefully this addition comes sooner than later.
