I was looking to buy four of these "Seagate Barracuda 7200.11 ST3500320AS 500GB 7200 RPM 32MB Cache SATA-300" hard-drives and set them in a raid 0 using an on-board raid-0 controller. However, some new reviews were just posted and they seem to only get around a 100MB/s with four drives? Does that seem right? I thought it be a lot more then that with four drives. Also, this is for uncompressed HD video work.
[cpp]Pros: All 4 came with firmware SD15 from Thailand, no problems, average 105MB/sec as singles, about 109.8MB/sec in RAID5 using a Sil 3124 controller. They probably would run better if I had a better controller but they do work nicely as is.[/cpp]
[cpp]Pros: I benchmarked 4 of these controlled by a sil3124 controller, in various RAID structures. The RAID0 set benchmarked at around 109.8 MB/sec, RAID5 came in about 65MB/sec. I caused the RAID5 set to fail a member by shutting down improperly, and it rebuilt in 45 minutes. It is a good idea when building the original RAID set to check the sil3124 RAID Manager software has actually completed the build before using the set. Using the set before it is built is sure way to keep getting failed RAID sets. Other than user error, these drives are working very well, and there is no other product offering 32MB cache for this price PLUS! a 5 year warranty!!!!! Name one source that does better, if you can, you better buy it, or you are probably not being truthful.[/cpp]

What I need at least:
1280x720p/59.94pfps = 106.8 MB per second
1920x1080/59.94ifps = 120 MB per second
1920x1080/59.94pfps = About 180 MB per second
