The above is new to me. Could someone enlighten me as to the differences on SATA 1, SATA 2 and SATA 3? Thanks,

As I understand it, hdds do not even use the full capabilities of SATA 2, so SATA 3 versus SATA 2 regarding an hdd does not really make a difference. Feel free to correct me if I am wrong. I am writing this from memory based on something one of the Gurus said on these forums.

See post #8 and post #9.

You are absolutely correct. No mechanical hard drive can break the sata 2 barrier much less sata 3. It was only fairly recently that SSDs could break the barrier. In my opinion, there is no sense in paying more for a sata 3 mechanical hard drive. Sata 2 hard drives will be just as fast.

My last "cheap" Seagate Barracuda was a sata 3. I just noticed by chance then realized it meant nothing really.

If I am buying a HD, do I have to make sure it is a SATA 2 and not a SATA 1 or is there no SATA 1 on the market now?

I believe that finding a new SATA 1 drive at this time is highly unlikely.

I believe that the Sata 1, 2, and 3 designations are unofficial. They're SATA 1.5, 3, and 6 Gbps. 1.5Gbps is over 187 MBps, which is fast enough for many mechanical drives. That was good enough for the original Raptor (10,000 RPM) drives from Western Digital.

I think SATA 2 (3Gb/s) is the de facto baseline now so I'd go with that but in this old test it appears the difference between SATA 1 (1.5Gb/s) and SATA 2 is marginal at best.
SATA vs SATA II
This gives a better description of SATA 1,2,3
Serial ATA - Wikipedia, the free encyclopedia

My conclusion: Pick a Sata 2 for a spinner (if it's sata 3 compatible fine but won't make a difference)

If your question was would it work, any sata drive will work they are all backward compatible.
