Probably too slow for folks who want to work in uncompressed HD.
From HDForIndies.com:
"Key thing of note - 199 MB/sec read speeds under RAID 5. Magic number for uncompressed 1080i60 10 bit 4:2:2 video: 200 MB/sec is the usual recommended number. For 1080p24 10b444 RGB: about 230-240 MB/sec. Whither write speed, Apple? Write speed is almost always slower in RAID 5 than read speed, so if read is about 200, and that's the minimum for uncompressed HD, where's the write speed? It is probably lower, and that's a bummer."
Also, is the 199 MB/sec over the whole array, or only the outside portions of the disk(s)? Again, could be problematic for the beefier flavors of HD.
