Comment on How bad of an idea is it to use computing HDDs in a DIY NAS?
Nollij@sopuli.xyz 3 days agoThis is highly dependent on what your needs are and how you plan to solve it. SATA-3 maxes at 6gbit, which SAS-2 had in 2009. Most cards are x8, and have at least 4 full speed SAS lanes (of whatever generation). That means 24 Gbit. PCIe x8 2.0 (from 2007) had 4 GB (32 Gbit). So if that meets your needs, you can run it on an ancient board.
However, if you need something more advanced, such as SAS-3, a SAS expander, or a card with more native lanes, then you would need to plan accordingly.
I’ve been running on an LSI 9211-4i4e, which is only a PCIe 2.0 card, for many years. I did notice my speeds dropped when I expanded the 4e to a 15-bay DAS (plus the 4 internal SATA drives), but it’s still enough to meet my needs.

I will definitely have to do my homework on all of these transfer rates lol
SAS drives are way cheaper on eBay and such but I don’t know if I feel confident enough to move from SATA to SAS for my first DIY NAS already. It sounds very easy with the PCIe SAS adapter but still daunting at the same time.
