I've had no problems with MySQL RAID, and the performance is excellent as long as you have your indices set up properly. One caveat I might add is that MySQL RAID does not apply to index files (.MYI). If your index files are going to grow > 4 GB, you'll need to consider alternate filesystems anyway.
For your reference, I'm running v3.23.42. My database has one primary MERGE table which collates the data from 12 month-specific tables. Each of those month-specific tables uses MySQL RAID with the following options: MAX_ROWS=2000000000 PACK_KEYS=1 RAID_TYPE=striped RAID_CHUNKS=32 RAID_CHUNKSIZE=256000 There are currently over 42 million entries in the MERGE table, occupying over 54 GB of disk. There are also various smaller lookup tables, etc. -- coop > The 2gig limit is a problem that I'm going to hit fairly shortly - perhaps > someone with a little more knowledge can tell me what the performance will > be like using mysql's raid rather than OS large file support?
