Hello list, I am having some pauses on MythTV, I read lots of post but
I don't know why is happening. I read this morning that it will be
about the disk transfer rate. So I check my drive.
I have a Western Digital Green 2TB drive:
Model Number: WDC WD20EARS-00MVWB0
Serial Number: WD-XXXXXXXXXXXX
Firmware Revision: 51.0AB51
Transport: Serial, SATA 1.0a, SATA II Extensions, SATA Rev
2.5, SATA Rev 2.6
I format with XFS this way:
mkfs.xfs -l size=64m -d agcount=4 -i attr=2,maxpct=5 -L mythfs /dev/sdb1
I mount it thi way:
# cat /etc/fstab
/dev/sdb1 /mnt/myth xfs noatime,nodiratime,allocsize=512m 0 0
I execute the test and this is the result:
# hdparm -tT /dev/sdb
/dev/sdb:
Timing cached reads: 1326 MB in 2.00 seconds = 662.71 MB/sec
Timing buffered disk reads: 368 MB in 3.00 seconds = 122.66 MB/sec
Are thoose numbers correct? I need to configure it other way?
I have no other machine to compare the result. I save the recordings
and livetv on same drive.
Thanks for your help and best regards.
