I'm having a RAID5 array of about 40TB in size. A separate RAID
controller card handles the disks. I'm planning to use the normal ext4
file system. It's standard and well known, most probably not the fastest
though. That will not have any great impact, as there is a 4TB NVMe SSD
drive, which takes the odd of the slow physical disk performance.
Yeah, we gave up on hardware RAID controllers long ago, but YMMV.
As for SSDs, if you spool the jobs you can run them in parallel to
spool->volume stream. You'd have to look at the numbers for your setup
but generally despooling off the SSD over the bus runs just fine while
clients are spooling to it over the network.
