[mythtv-users] LVM RAID 5 partition schemes

[Schlomo Schapiro]

Hi,

careful about temperature i regard to HDs ! I found out that e.g. Samsung 
200G PATA disks consume only about 9w power whereas other (faster, bigger, 
better) drives consume 15-20w, which results in a huge difference in 
temperature output. I would recommend to use more low-power drives than 
fewer high-power ones.

Just my 2c ...
