How much speeds (data transmission rate) can be achieved with SATA 1, SATA 2 and SATA 3 and what feature should be enabled in a computer to utilize the high-speed SATA drives?
Hey There ,
SATA I (1.x) :
Data transmission rate : 1.5 Gb/s
Bandwidth throughput : up to 150MB/s
SATA II (2.x) :
Data transmission rate : 3 Gb/s
Bandwidth throughput : up to 300MB/s
SATA III (3.x) :
Data transmission rate : 6Gb/s
Bandwidth throughput : up to 600MB/s

For a system to utilise the high-speed SATA drives ,there are multiple SATA controller modes which is available in the BIOS.
AHCI ( Advanced Host Controller Interface) : It provides the best performance with SATA storage device. (modern standard for SATA controller operation)
IDE (Integrated Drive Electronics) :Slower performance and worst support. This is a legacy standard from 1990s.
RAID (Redundant Array of Independent Disks) : Multiple drives are merged into one for performance benefits . But it can be used only if the system supports this configuration. It varies from system to system.
Please let me know, in the comments section if u have any queries. Consider giving a thumbs up! Thanks!
