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/ > ## Conclusion > Our results confirm that despite the faster hardware available today, there > is still no performance difference between SATA 3Gb/s and SATA 6Gb/s cables. > The SATA 3Gb/s revision only supports transfer speeds around 300MB/s, yet we > saw transfer speeds up to 500 MB/s with each cable that we tested. Avsak je to test z February 11, 2013, tak mozno s modernymi SSD by sa sem-tam mozno niekde nejaky problem nasiel. > Vyssi prenosova rychlost znamena vyssi utlum (pri stejnych parametrech > kabelu) a vyssi citlivost na jitter. 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).
