Re: RAID 0 or LVM?



Hi,
Im using RAID 0 in a UDMA disk with 4.5GB 7200RPM and we tested reading and 
writing 1GB file so here is the results (This test giving a results of 1 disk):
For 512 byte blocks we get:
Write (bytes/s): 5,520,807 Read: 9,625,655 CPU Load in %s: 26.1
and for 8192 byte (8kB) blocks we get:
Write (bytes/s): 5,987,853 Read: 9,472,799 CPU Load in %s: 19.2

I heard about LVM but I never tried using it. You can read about it in:
