Expensive hardware RAID for a simple RAID0 array? LOL! Dont waste your money please. Even the most expensive hardware RAID are slower than software RAID when it comes to random IOps benchmarks; Areca ARC-12xx seems limited to 70.000 IOps. There can be several reasons your RAID0 is not functioning properly: - you have a 'bad' partition (misaligned) starting at 31.5KiB offset - you have multiple partitions on the RAID; and the second partition is not properly aligned - the selected stripesize is too low (< 128KiB) - you defragmented your SSD at least once during its lifetime (you need a full zero write to regain performance) - you performed inadequate benchmarking (low queue depth) If you want some serious advice and really solve this issue, you must do some work yourself: - explain your setup in more detail (enabled the 'write caching' option in Intel drivers? How did you create the partitions? Can you check for the partition offset, etc) - post proper benchmarks performed at the filesystem level, for example HDTune Pro's "File" benchmark. The normal HDTune benchmark only tests raw disk access; without using read-ahead which your filesystem does use to allow parallel I/O processing. If you can do that, i might be able to help you out with some specific advice.
