Hmm, 55MB/s is pretty fast for a single IDE drive. The only time you will approach 100+ mb/s is talking directly with the drive's cache. Not even 15K SCSI drives do much over 60MB/s as the drive physically can't read and write 100+ MB/s. with a 2.6.5 custom kernel, I was getting 80MB/s across a software raid 5. With FC2 Test 2 and one of Arjan's first 2.6.5 kernels, I was getting 74MB/s which is pretty good. I assume the difference may have been due to Arjan's Kernal not having stuff premptive enabled. Ultimately I think you will find that Linux Software RAID will be much faster and better supported the SIL3114 hardware RAID. Of course windows doesn't support Linux Software RAID so you can't use RAID in windows. However since Linux software RAID is partition dependent and not drive dependent, you can run software RAID under Linux and no raid in Windows while still using the same disks. Also software RAID allows things like using RAID 4, 5 or 6 or including PATA drives in the Array as well. Also it allows for different RAID levels for /usr and /home partitions, etc. -- Mark Lane, CET mailto:mark@xxxxxxxxxxxx Hard Data Ltd. http://www.harddata.com T: 01-780-456-9771 F: 01-780-456-9772 11060 - 166 Avenue Edmonton, AB, Canada, T5X 1Y3 --> Ask me about our Excellent 1U Systems! <--
