A new Seagate 4Tra drive works really, really slowly


Recommended Posts




I purchased a drive New 4Tra, an internal drive that should be used as storage for all the sailing I have on my computer.

Seagate Barracuda HDD 4TB Sata III ST4000DM004

I started backing up all the stuff and noticed that the writing / reading speed is so shocking and slow that the speed goes down to 0 and then goes up to 2 MB and then goes down back to 0.


A test of the Mark disk gives 75 megabytes in reading and 8 megabytes in writing. 


The drive is connected in SATA3 and all tests of Also showed that everything is fine, the drive is formatted in NTFS.


Beyond that I have no idea what can be screwed up and why there is such a shocking speed, maybe the drive is screwed up?
