State Drives for Your G4!
Cheryn tells me
we are having trouble finding 80 or 120GB refurbished
hard drives for our older Mac customers. There haven't
been new ones available for years. We know you depend on
us to help keep your old gear running efficiently. These
brand new digital solid state drives have no moving parts
making them not only faster but more reliable. We still
think you should keep your system backed up but running
from these super fast brand new drives only make sense.
We haven't carried SSD drives much before but we think
now that the prices are more affordable now is the time.
We found the right kind of adapter that allows you to
configure it for Master, Slave or Cable Select depending
on your needs. That makes these more compatible and
easily configurable with an included jumper. We can set
these up for your system or you can use copy software to
move your old data. Let us know how we can help speed up
your G4 system. I tested these on our servers so you know
they are fast and dependable.
