Last night my friend told me to download HD tunes to check the transfer rate of my HD's.
I'm editing a movie has over 2,000 media clips in it so its the bottle neck on my pc.
I have 2x hds stripped and 1x 2tb HD but the 2tb seems to run faster on the test.
A: I have raid stripped 2x Samsung HD103SJ Spinpoint F3 1TB Hard Drive SATAII 7200rpm 32MB Cache - OEM, says the transfer rate high end is 100mb.
Automatically I though it should be 300mb was its a sata 2 cable and 600mb for sata 3.
But not looking at HD charts I see 200mb is on the high end unless its SSD.
My other HD is Samsung HD204UI Spinpoint F4 2TB Hard Drive SATA2 5400RPM 32tbs runs at 160mb thsi is where im puzzled it lower rpm but faster transfer rate.
1: How come the 2x HDs are running at 100mbs? i'd have thought if they where stripped they'd run at a hd speed plus a half.
2: So does this mean my samsung F4 running at 160mb would be better then the raid?
3: Can I copy the stripped raid 2x HD onto one HD.

RAID 0 with 2x 1TB SATAII and get 100MB/s, I would blame it on the enclosure...
a_ the raid engine is a lousy
b_ SATA to eSATA chip set induce latency to the bus and slow down data.
c_ Too noisy (electrical) so the data get so much invalid data and have to retried.
All and all it's the enclosure.
To test it, you can to this:
Back-up your data
Connect 2x Samsung drive to MB's SATA port
Use Disk Management configure RAID0 (software RAID0)
I'm pretty sure you can get 200MB/sec or more with HD tunes
