We use 250GB Hard drives for this.
Lets put it to the test and see what the results are.
Average results over 4 runs with pveperf:
Number of HDD's CPU BOGOMIPS / REGEX/SECONDS / Buffered Reads / Average Seek Time / FSYNC/SECOND
4x WD2503ABYX 250GB 100546.56 / 881431.50 / 264.73 MB/sec / 6.41 ms / 3080.16
8x WD2503ABYX 250GB 100549.56 / 820746.50 / 746.70 MB/sec / 6.04 ms / 2829.63
Conclusion:
As you can see the buffered reads are almost 3x times higher with 8 disks then compared with 4 disks. Although FSYNC/SECOND went a bit down.
I would say put in more smaller harddrives then just a couple of big ones.
Bigger is not always better ;)
