Commentary from my husband, who is a storage geek:
Mine is relatively small... only a 4-port setup, 2 internal/2 external.
For native linux support, the LSI MegaRAID controllers are open source
and part of the kernel, there's no 3rd party driver to install.
Something like this has 8 internal SAS/SATA ports and is about $300.
It appears to be out of stock, not sure if it's been replaced by
something else or is just a big seller:
You'll want at least one PCIe lane for every two drives as a minimum
for decent performance. A 4-port PCI-e x1 controller card is cheap,
but can't get anywhere close to saturating 4 disks.
