So I have a Seagate 3TB Drive (ST3000DM001) for less than 2 years that I pulled from an Expansion external USB drive because the USB adaptor went bad (windows wouldn't detect the drive).
I recently upgraded to a 6tb WD blue drive as my main storage / backup drive however (got it for $110 brand new )
I formatted / cleared the 3TB Seagate to keep as a second backup drive. I noticed when I try to copying large data files to it (ex. Backing up the Battlefield 1 installation cache), the write speed will start out around 100-110MB/s for about 30seconds then it'll drop to like 50MB/s and then like 20-30MB. WTF?
Any idea what would be causing the 3TB drive to write so slow?
Is the drive failing?
Is there a special way I should try formatting or do a CHKDSK to fix this issue?
Thanks for your help.

- I tried swapping SATA cables with no luck.
- I checked Crystal Disk and it says the health is good.
- I tried copying the same exact data to another Seagate 2TB drive I have (ST2000DM001) and it copied much faster at like 120MB - 140MB/s so it seems something is up with this 3TB Seagate drive.
