lilpyro, RAID doesn’t really work that way. The issue with writing to SSDs and Flash memory in general is that sometimes the disk has to do a bunch of housekeeping before it can reclaim an empty sector, and this housekeeping is time-consuming. When that happens, the write does not fail, it just takes a very long time to complete, and RAID won’t help with that. It’s a shame that the uTrack24 doesn’t have more internal RAM. A large RAM buffer would enable it to ride out these occasional write latencies.
This is only an issue for writing (recording). For playback I would expect that Flash memory would be fine, as FOH suggests.
