SATA HDD and main board compatibility.

[None of the above]

I fitted a second SATA HDD to my PC as a back up device. Given the fact that it had become noisy, and files were taking an extended time to open, I assumed that the drive was about to expire and removed it.

When looking for a replacement I found that most drives are described as SATA-III. The old drive was salvaged from an earlier machine and there is nothing to indicate what 'flavour' of SATA it is/was.
The motherboard is a Gigabyte GA-P55-US3L and the relevant part of the spec is here:

Chipset:

1. 6 x SATA 3Gb/s connectors (SATA2_0, SATA2_1, SATA2_2, SATA2_3, SATA2_4, SATA2_5) supporting up to 6 SATA 3Gb/s devices

GIGABYTE SATA2 chip:

1. 1 x IDE connector supporting ATA-133/100/66/33 and up to 2 IDE devices
2. 2 x SATA 3Gb/s connectors (GSATA2_0, GSATA2_1) supporting up to 2 SATA 3Gb/s devices
3. Support for SATA RAID 0, RAID 1, and JBOD

iTE IT8720 chip:

1. 1 x floppy disk drive connector supporting up to 1 floppy disk drive

Is it necessary to use a particular spec of SATA drive or will any variety be compatible with the main board?

Thank you in anticipation, Gentlemen.

PS It is some time since I last bought a HDD and prices seem to have soared to horrifying levels.
