TODDLT Posted June 22, 2011 Share Posted June 22, 2011 Is there really a SATA 1 and SATA II rated cable? I am seeing a lot of advertisements for cables that just say SATA, and then some that specifically say SATA II. I've seen a few that say SATA III. Quote Link to comment
speeding_ant Posted June 22, 2011 Share Posted June 22, 2011 As far as I know, they're all compatible. SATA III might have a length limit though? Quote Link to comment
thisisepic0727 Posted June 23, 2011 Share Posted June 23, 2011 If you do some searching, you'll find that some people say that SATA I, II or III are marketing ploys. Maybe there is some truth to this, I don't know, but supposedly, they are really all the same. We discussed this a little bit in this thread. I use SATA I cables in my unRAID built that I bought from MonoPrice and they work fine. From what I understand, most hard drives do not write at speeds that a SATA III cable is rated at anyways, so at this point it doesn't make much of a difference what cable you were to use.

I'm not sure that is true. Even though the data transfer to magnetic disk cannot achieve a sustainable 6Gb/s, I would hope that two SATA3 devices would be able to reach 6Gb/s on the cable between them. Quote Link to comment

I'll give you that, I should have worded my sentence better. I was alluding to the point you made about the data transfer rates, but I didn't really do a good job at making that part clear.

TODDLT Posted June 29, 2011 Author Share Posted June 29, 2011 OK, I ordered 4 - 7" "SATA II" cables. pretty cheap on ebay but seller had a 99.6% rating and it's not like I was going to be out lots of money so I'd give it a shot.'' They came in today and other than just short, they are really narrow. The width of the cable is probably 2/3 or less of the cables I have. I was a little worried, but put them on the HD's that are going in the UnRAID server. They seem to be fine. I could copy from drive to drive at 100 MB/sec internally and 70's - 80's externally. I haven't got those speeds in a while. Quote Link to comment
MrD1234 Posted June 30, 2011 Share Posted June 30, 2011 Curious how much you paid for those. I have dozens of sata cables in a box, that I've collected over time. Every motherboard I get comes with 6 or 8 cables and I never use them. Quote Link to comment
Superorb Posted July 4, 2011 Share Posted July 4, 2011 There is no difference between the cables, but often times people will call the latching cables Sata II cables. Quote Link to comment
