I have a gigabyte x58ud5 and a Samsung evo 500gb ssd. Are speeds below what I should be getting and do my bios settings look ok? Should bottom "onboard sata/ide" be set to disabled?
I switched to AHCI without reinstalling windows a while back. I'll do a fresh installed if that's what I need to do.
I am plugged into the intel controller.

Is it older SATA? You won’t get the full bandwidth throughout of the SSD with older SATA.

Super weird that the board has no SATA3 ports. Depending on use, it may be worth investing in a PCI-e ssd adapter card. I used an Apricorn solo card that gave me full ssd speeds.

If OP is going to get a PCIe 6Gbps SATA card, he might as well just get a PCIe to M.2 adapter card and use an NVMe SSD.

Not at all. SATA3 was introduced about halfway through the X58 lifecycle so first gen boards like the EX58's didn't have it, while the refreshes did via add-on controller chips, but even those had their teething issues.

A lot of bioses aren't NVMe aware. I had a Samsung 950 Pro installed via M.2 adapter, but you're limited to PCIe 2.0 bandwidth. The 950 Pro works because it has a legacy ROM on the drive so it shows up in non-UEFI bioses.

As others have mentioned, it's the SATA2 limit. Specifically SATA2 is 3 Gbps with 8b/10b encoding, so 2.4 Gbps after encoding. Then there's ~10% of overhead which takes it to 2.16 Gbps or ~276 MB/s.
