[測試] 買左個crucial mx 300 275g

主板sata位唔夠插,想用pci e既sata擴充卡插,速度會唔會比插pcb慢?


所以將HDD駁去pci-e sata card
SSD直插底板

    原來我張pcie sata card係行sata3.....咁應該都唔慢掛?

PCIe 2.0 x1 = 500MB/s
SATA 3 = 600MB/s per port

SSD實際係可以超過 500MB/s 的
除非你張卡有 PCIe 3.0,或者係 2.0 x2 以上,否則唔足速

what you are saying is the maximum theoretical bus speed.
  the real speed of these pcie to sata card is about in between sata2  and sata 3 which is around 350MB/s

買pci-e ssd

應該都係會慢,以前主板onboard嘅廠外加sata3都會慢過原生sata

轉接始終沒有原生好,首選直插底板

如果用黎boot機同裝windows,建議都係用返底版原生個controller

冇用, random i/o輸哂, bandwidth幾大都冇用
除非你買LSI果D
