Extremely low write speeds?

I'm using a Western Digital Caviar Blue 1TB hard drive which runs at 7200rpm yet apparently my write speeds are only 14MB/s at their peak. I have no idea what has caused them to be so low and I am about to defrag to see if it will help but there's only 4% fragmented. Anyone got any ideas as to why the speed is so low?

Hi there judson97,

I'm sorry that you are facing some issues with your WD drive. :(
As there may be something wrong with it, it may be a good idea to back up the important data that is stored on it.

What SATA port it is connected to? Make sure it is connected to a SATA 3 one(MOBOs have different SATA ports). You can double check the connections as well: change/swap both SATA and power cable. Try another SATA port as well.
If the issue persists, you can test the drive with WD's Data Lifeguard Diagnostic tool. The results will provide its overall health status.

Also, you can consider what burdenbound mentioned. Try transferring one big file instead of many small ones.

Thanks for the fast response :)

For some reason, it skipped my mind to try a different SATA port...

I was using a SATA 3 port before but decided to move it to a different port which is also SATA 3 and it seems to work. I'm not entirely sure whether it was the fact that I moved SATA ports or plugged in my expansion drive which fixed it but I now have write speeds of 180MB/s :)

One thing which I'm not too sure about though is; I'm using the SATA 3 port but the cable says Serial ATA 6G on it so I'm not sure if they are compatible?

Anyway thanks for the help :D

I was using CrystalDiskMark to check my speeds as I noticed my fps was very low when recording games. I only have 1 HDD and unfortunately I cannot buy another at the moment as I'm a broke student :p

The problem is fixed now anyway by plugging in an expansion drive and changing the SATA port. Thanks for the help anyway :)
