Ovo vrijedi i za prijenosna ra\u010dunala i za servere. Na serverima, mo\u017eda je samo razlika u tome \u0161to se SSD mo\u017ee lako kombinirati u RAID.<\/p>\n<p>Istina je da postoje sitni detalji povezani s tim da stari server mo\u017eda nema SATA III portova i tada \u0107e biti potrebno zamijeniti ili dodati odgovaraju\u0107i kontroler.<\/p>\n<p>Naravno, postoje i me\u0111ufazi<\/p>\n<h2>Ke\u0161iranje na SSD-u.<\/h2>\n<p>\nOp\u0107enito, ovaj na\u010din dobro odgovara za baze podataka, 1C, bilo koji slu\u010dajni pristup.

Klju\u010devi i SSD-ovi za CacheCade morat \u0107e se kupovati od IBM-a po nevjerojatnim cijenama, stoga je lak\u0161e zamijeniti kontroler s LSI i kupiti jeftiniji hardverski klju\u010d.

Zanimaju nas verzije kontrolera koje zavr\u0161avaju slovom Q.<\/p>\n<p>Q-kontroleri mogu koristiti gotovo svaki SSD, a ne samo SSD-ove koje isporu\u010duje Adaptec.<\/p>\n<ul>\n<li>Od verzije 5xxx svi kontroleri imaju podr\u0161ku za Hybrid raid.
