Cable limits SATA interface?

[Murilo_A]

I'm going to buy a new SSD and a SATA cable, I found one that is only capable of SATA I and II (at least in theory), but there are people on the reviews that tell it's capable of handling SATA III. As some interfaces (like HDMI) are not affected by the cable, I was wondering if SATA also works that way.

All sata cables are the same. 

 

P.s. HDMI cables can actually matter -- as they don't all have the same bandwidth (but all HDMI cables with the same bandwidth are identical).

HDMI is designed to carry more data, around 8.16 gbps for hdmi 1.3 and 1.4, about 14 gbps for 2.0. 

SATA cables carry only 6 gbps (3gbps for sata 2) and are much smaller length (must be at least 12 inches or 30 cm and maximum 1 meter but 50-70 cm cables are more common, while hdmi is up to 10 meters and Displayport is up to 3 meters), so there's less precision required in making these cables, less insulation, less everything..., which means even cheaper cables are capable of the sata 3 speeds.

Hi there

 

As @djdwosk97 pointed out, SATA cables are all capable of handling all SATAI, SATAII and SATAIII data rates. The only differences between SATA cables may be the latches at the end of the cables that contribute to a more secure connection. 

Any SATA cable should do the job. Some limitations that you may see are that SATA cables have a limit of 1m in length, SATAI ports have a limit of 1 device per channel where SATAII and above can have up to 15 with port multipliers, etc.

 

Let me know if you have any questions!
