Here the same situation exists: there is no significant performance difference between the FastTrak and the MegaRAID. In fact, it's eerie to witness how similarly these two cards perform in RAID 0. The Workstation, File Server, and Database performance of both adapters increases somewhat in a 2-drive RAID 0 array relative to a single drive, but then unfortunately stays about the same when moving to 3 and 4-drive RAID 0 arrays. Random write performance scales as more drives are added to both cards, as does (for the most part) sequential write performance - both cards max out at a fairly impressive 75MB/sec.
