Chcel som napisat, ze podla testov, co som pozeral, tak medzi SATA 2 a SATA 3 *kablami* nie je rozdiel v rychlosti.

Konkretne som narazal na tento test:

SATA 3Gb/s vs. 6Gb/s Cable Performance (Revisited)
https://www.pugetsystems.com/labs/articles/SATA-3Gb-s-vs-6Gb-s-Cable-Performance-Revisited-183/

Avsak je to test z February 11, 2013, tak mozno s modernymi SSD by sa sem-tam mozno niekde nejaky problem nasiel.

To dava zmysel. Len ma to nikdy nenapadlo, ze SATA kabel treba riesit. Ten SATA 3 kabel vyzera rovnako. U PATA kablov vyzerali rychlejsie kable inac (mali 2x viacej zil).
