What does "hdparm -tT" show you?
hdparm -tT /dev/sda
/dev/sda:
Timing cached reads: 2256 MB in 2.00 seconds = 1127.93 MB/sec
Timing buffered disk reads: 112 MB in 3.08 seconds = 36.41 MB/sec
Two SD and one HD stream is a *lot* of data, you may be hitting the real limit of the drive system.
Yes, it is a lot of data... My orig plan was to use a SATA II controller
(but didn't know at the it required pci-e at the time)
Hmmm... Anybody got numbers/experience with Hardware/Software Raid 0? Did it result in increased bandwidth?
(Less likely with software, I know)
