rychlost hdd
Napsal: 28 dub 2016 20:51
Dobrý den, na záložním PC mám starší hdd připojený přes Pata 133. Dnes jsem připojil ješte jeden jako datový, tento už má rozhraní Sata2. Změřil jsem rychlost obou disků přes Crystal disk mark a pata hdd je znatelně rychlejší ve čtení, čím to může být? Připojuji výpis z programu:
