Jeste bych mozna moh dodat, ze pouzivam LVM, ale zadny zrcadleny nebo prokladany oddil a zadny logicky disk nejde pres vice fyzickych.
Ale zda se, ze lvm to nezpomaluje:
# hdparm -Tt /dev/sdd
/dev/sdd:
Timing cached reads: 3888 MB in 2.00 seconds = 1945.30 MB/sec
Timing buffered disk reads: 292 MB in 3.02 seconds = 96.80 MB/sec
# hdparm -Tt /dev/data/video
/dev/data/video:
Timing cached reads: 3890 MB in 2.00 seconds = 1945.92 MB/sec
Timing buffered disk reads: 288 MB in 3.00 seconds = 95.99 MB/sec
