  1. I thought this was pretty clear: One drive is now almost full (345 GB free) while the other has 5.78 TB free. Write speeds on the almost full drive have remained steady at ~100 MB/s. However on the other drive they have fallen to ~17 MB/s. <- the 5.78 TB free drive Regardless, the issue has disappeared for now (see Jan 11 post).
  2. I doubt it. The drive had been hooked up for a few days and there was only a few thousand files on it. Any initial scans should have long since finished.
  3. There's no fragmentation (makes sense as it's a new drive, only written to). However I disabled access from a couple of anti-malware and performance monitoring programs that were constantly performing reads on the drive and write speeds went back up to 100 MB/s. Kind of strange the other drive was not affected.
  4. I set up two Seagate STDT8000100's last week as backup drives and proceeded to copy over files. One drive is now almost full (345 GB free) while the other has 5.78 TB free. Write speeds on the almost full drive have remained steady at ~100 MB/s. However on the other drive they have fallen to ~17 MB/s. Read speeds on both are at ~150 MB/s. I'm aware that SMR drives have poor random write speeds but I'm at a loss to explain why the first drive has suddenly dropped in write speed. I'm copying the same 250 MB and 5 GB files (stored on an internal hard drive) to both drives as a test.
