Geleneksel Sabit Disk S\u00fcr\u00fcc\u00fcleri (HDD), mekanik par\u00e7alara sahip olduklar\u0131 i\u00e7in daha yava\u015ft\u0131r. Kat\u0131 Hal S\u00fcr\u00fcc\u00fcleri (SSD) ise verileri flash bellek yongalar\u0131nda saklayarak \u00e7ok daha y\u00fcksek okuma\/yazma h\u0131zlar\u0131 sunar. NVMe (Non-Volatile Memory Express) SSD’ler ise en yeni teknoloji olup, do\u011frudan PCIe veri yolu \u00fczerinden ileti\u015fim kurarak standart SSD’lerden bile kat kat daha y\u00fcksek performans sa\u011flar.
