Is the M1015 still the best bang for buck for NAS builds?

In 2014 I purchased and still use an M1015, now that I am building a second NAS while keeping the original still online I am wondering if I should buy yet another M1015 or if there may be something better/newer?

My use case: Linux Debian/Proxmox based NAS with 8 disk drives.

The IBM M1015 is great, I own one myself. It's an OEM version of the classic LSI SAS-9210/9211 HBA based on the LSI 2008 chip, with reliability proven by millions of hours of use.

Nowadays for 6Gbps systems I buy HBAs based on the LSI 2308 chipset, which gives a slight improvement on the 2008, and is more than adequate for SATA disks.

Unless you're planning to use more modern SAS3/12Gbps disks, either one will serve you well. But for SAS3/12Gbps, get an LSI 9300 card based on the 3008 chip.

Just my two cent's worth.

Another PLUS for the 2308 cards is if you're tight for PCIe lanes (gen3), you can give them x4 and get 3400 MB/s total throughput (vs 4700 ~4500 if they get the full x8).

You (OP) specifically mentioned Debian/Proxmox, so M1015 should be fine compatibility wise, but in case you are to consider something else you may run into compatibility issues. Both ESXi 7.0 and RHEL 8 do not support cards based on the SAS2008 controller.

And while you did not specify what kind of disks you are planning to use, you may get bottlenecked if you are to use SSDs.
Here is a thread where the differences between 2008 and 2308 is discussed:

Personally I would buy SAS3008 or newer unless you have something lying around.
