ROTFL. I am sorry but 'consumer' 7200 RPM PATA/SATA drives can very well
do 24/7 for years. Did you read Google's report? There is NO DIFFERENCE
in terms of endurance between SCSI/PATA/SATA drives.
I worked for an outfit that handled over 40 million mailboxes and
tackled around 200 million smtp transactions daily. My responsibilities
were the mail delivery system with over 30 boxes under my direct
adminstration. I did not get more trouble/failures from PATA or SATA
drive boxes than SCSI boxes.

Where have you been in the last few years? SATA is hot swappable from
its conception. Almost any SATA controller can do hotswap. Support for
hot swapping under Linux for SCSI had been a hack job for admins and
only recently has that changed. SATA hot plug support is in Centos 5 for
AHCI compliant chipsets, Silicon Image chipsets which covers quite a few
onboard SATA motherboards.
The problem is not my mush but yours. Yours is stuck in the last decade.
