[Asterisk-Users] RAID affecting X100P performance...

[Dana Nowell]

In an article on IDE vs. SCSI I read that MTBF numbers for IDE were
frequently caculated at 8 hours on 16 hours off per day (assumes desktop
usage) but SCSI drives were calculated at 24hrs on per day.  So even though
the MTBF numbers look the same ...  The main reason is, reportedly, better
quality controller parts and motors.  Before someone asks, no I don't
remember where I read the article (probably via slashdot), you might try
google.
