Two of the same model HDD, very different speeds

[roughavoc]

Me and my brother both have a Seagate ST400DM004 (4TB) drive in our systems, both have roughly the same amount of data written, same hours powered, same basically everything

The issue is when I run any hard drive benchmark software, lets go with CrystalDiskMark for now

His Drive -- My Drive

 

What could be the reasons for the difference in speeds? I know it isn't the platform as his system is my old system and my speeds haven't changed since going from Intel to AMD.

What SATA cables are you guys rocking?

As Jasun already said it could be your SATA cables, and if not it could just be a scenario where his drive has held up way better than the average one and yours has slowed down way more than the average.

Standard ones that come with the motherboard, both new cables (Z87 / B350) so it shouldn't be those

Also, have you cheked to make sure the hard drives were defragmented? Windows usually does this on it's own, but could be worth checking.

The drives are 2 months old, both 1% fragmented

I guess I have just lost the luck game

You could check yours with our free diagnostic software SeaTools just to see if the health of the drive could be a factor.
