anyone had success putting an SSD in a G5 and getting the maximum speed out
of it? issues i'm aware of include the native SATA-1 interface, which will
limit speed to a theoretical max of 187.5 MB/s, regardless of how fast the
SSD itself is. the way around that is to use an expansion slot and a
SATA-2 or SATA-3 controller. problem is, i'm having a hard time finding a
PCI-e SATA-3 controller that's compatible and bootable. i tried one of the
Apricorn Velocity Solo cards (PCI-e/sata-3 controller and carrier for 2.5"
SSD), and it is indeed bootable in a 2009 MacPro, but it is invisible in my
G5 quad. system profiler and disk utility don't even know it's there.
it's "supposed" to work in ANY computer with a PCI-e slot. waiting to hear
back from customer support.
one bit of good news i can share is that at $43 (sans drive) it was an
appealing alternative to the much more costly Sonnet cards, and
outrageously expensive Accelsior cards, and it works flawlessly in a
MacPro, delivering a read/write speed of 480 MB/s (if your SSD is up to
it), just not the G5 i intended it for.
anyone have any other suggestions, or success stories with other hdwe? TIA
for all replies.

Trim is outside the realm of possibility. Not sure If doing an erase free space procedure monthly or so would help a bit. Modern drive "garbage collection" is pretty good. Anybody got any benchmarks? I picked up a velociraptor to use in an old G4 rather than try to work through SSD issues.

Hello,
While trim is not going to be supported (unless
there is some third party utility) The SSDs firmware
will perform the garbage collection without the OSes help.
I was thinking about a velociraptor myself for a
fast boot drive but what about a segate momentus
hybrid SSHD?
It caches reads and learns the most used programs like those used at boot.
Writes are just the same as a spinner though.
Not sure about the noise of the raptor as well as
the SSHD will be faster assuming the firmware
GC is up to the job.
