Yes, it is OK to have the 4Gb disks in the SSA110, providing you have
an up to date power supply:

It depends on your power supply.  The 7200 RPM disk drives consume more
power than the 5400 RPM disk drives. Model 100 Series chassis with older
revisions of power supply (300-1098-03 or -02) may require an upgrade to
revision -04.  If a tray contains eight or more 7200 RPM disk drives, an
upgrade to the -04 supply (order number 540-2465) is necessary.  All
disks coming from Sun these days are 7200 RPM - since March.  You need
to know what type of power supply and disks you have in the 110.
THis is right out of Sun's Price List Manual.

I've decided to just add a Multipack to the machine instead
of messing with the SSA.
