Sata 6GB/s Meaning and how it works

[Ragahv]

Hey i want to know how this feature of the msi x99s gaming 7 MB works. Its called SATA 3 6GB/s and i dont really get that speed when i transfer a 10 gb file from one disk to another. Do i need a specif driver software in order to run this service or can i just work it when i have finished installing OS like windows 7.

I have relized i dont get that speed 6GB per second!!! no way only get 2KB/s not 6GB. Whats wrong please help me get the full potentail of my motherboard. I think that my MB has failled to work some features because all my transfer files and speeds are not even 1gb p /s

It's not 6GB/s, it's 6 Gb/s, 8 bits in a byte and with overhead you'd be maxing out around 550MB/s on a good ssd. On a hdd you'd probably only be getting around 150MB/s max. Btw max speeds are sequential so real world is going to be slower but test speed with something like crystaldiskmark. Make sure you're set to ahci in bios and as long as the sata drivers are installed, it'll work without issues.

Ok thanks for that information however when i transfer files from one hdd to another external hdd. I notice that the hard drive transfer is only 2Mb/s and i dont know why its happening. My disks are sata 2 but the MB features sata 3 so will it still work with that Gb/s speed?

6 gbit/s is the speed of the internal highway, but you will not attain that speed since the cars (HDD) involved can't go that fast. The effective speed of the transfer can only go as fast as the slowest component in the system, in this case am thinking limited by the external drive, perhaps on a USB1 connector.

With the hdd only being sata 2 then you are limited to that but that must mean those hdds are over 5 years old. We need specific model numbers to be sure what the issue is. What hdds? Are you transferring lots of small files?
