Re: RAID & Hard disk performance

My experience with the new Maxtor drives is very positive. They perform
well and seem very reliable. Seagate drives however seem to be very
sensitive to knocks and bumps.

However, I must agree with you on the raid5 solution... for large raid
setups, the only practical solution is SCSI. As for cooling... those
>10000rpm drives sure do run hot, so cooling is of utmost importance.
