G5 with my "NEW" Areca PCI-X RAID-Controller

I only have 1 SSD (from my 9600) to test. I wish I could make a RAID with 3 or more SSDs. 🤪

Those read speeds are too high, so I strongly suspect it's reading from the Areca's cache.

2 SSDs (1x840 Pro 120GB 1x850 Pro 240GB) connected to my Areca PCI-X RAID. In a weak, or so, i can test the with 3x SSDs and 2x more modern SSDs with the same size and specifications.

Today i have tested 3 SSDs connected to my Areca 1160 with sobering results.

It looks like the speed of the controller is limited to around 400 MB/s. You can boost the read or write speed by "write through" or "write back"

Is anyone out there wo get the full speed (~700 MB/s) out of the PCI-X 133 MHz slot?

Those are some impressive speeds; thanks for sharing your results! I wonder if there is a similar card for PCI/G4 computers.
 
Late 2013 MacPro (trashcan) connected to ARECA ARC8050T3U-8 using Apple's USB-C to TB2 adapter (MP has TB2 only), using a single PM1643 SAS-SSD (1.8TB). This is basically my FCPX working disk. On the same enclosure, a RAID-6 to store my data.

Have the ARECA since 2019, rock solid (before I had PROMISE R6, after 5 years backplane unstable).

Now the bottleneck with FCPX is the heat INTEL Xeon generates.

Edit: apologies, missed where it says "PPC"

Not really a PowerPC Mac and not really impressive (My MacPro 2010 is faster) ;)
