Slow hdd speed !

[sarabjeet24]

I have a samsung 320gb 7200rpm hdd but when I ran speed test with crystaldisk 6.0 it's speed are as follows 

 

Read speed- 45-50mb/s and in other read speed columns it was even low as 0.9 mb/s

 

Write speed- 100-110mb/s and in other write speed columns it was about 0.9-1mb/s

Is it plugged into a SATA 3 port?

No bro it's plugged in SATA 1 port!

[XAIXER]

That would explain the speed then. SATA 1 is 4x slower than SATA 3.

You could always get a SATA 3 controller card.

But it's checking the C drive?

It maybe fragmented, you can try defrag.

Check the disk and try to repair any errors.

Depending on the age, it might just failing.

You should prepare a replacement drive, ssd recommended.

Click on the drive drop down and choose the 320 gb hard drive.

Sorry it was just that you wrote that it was a 320Gb and the partition didn't show anything more than 78Gb.

What does CrystalDiskInfo say about the drive?
