I'm not sure about that. I've got another ACARD unit (the faster SCA
model) that I use in my Tezro. I also have a second disk (the Tezro can
hold a couple) that's a spinning rust 15k Barracuda. I don't have numbers
right now (next time I fire up my Tezro I'll get some). However,
anecdotally, the ACARD disk (also predicated on a Samsung 850 Pro SATA
SSD) will absolutely stomp the Barracuda's guts out in every stat and
especially on latency.
The main time I can "feel" it is when I run Photoshop or a browser. The
SSD-based ACARD makes the system feel a lot faster. Pages finish loading
faster, 'rqsall' takes about half as long, packages install much more
quickly, and the silly delays you get when 'inst' is reading package
metadata takes a lot less time. I curse at it only about half as much (I
love IRIX but 'inst' and I aren't pals - I haze it often).
I know that's all anecdotal, but I'm pretty sure I tested the disk when I
first got it and it blew the rust-based drive away. I've just got my bench
all covered with Quadra 700 parts and various jury-rigged SCSI cables so I
can install from CDROM on a machine that doesn't have space for a CDROM
etc.. When I finish refurbing this thing with a MacOS + A/UX 3 dual boot
rig, I'll grab the SGIs. I'll try out the ACARD vs SCSI2SD on my R5k/180
