Here is my experience, and hope you have collaboration or comments. When I started to use the 300gig drive, it was empty, and things worked at usb2 speed. As the drive reached the 250gig level, activity to the drive started to slow to a snail's pace. Now at the 275 gig level, writing to the drive stalls for minutes on end. I tried different things such as issuing a sync command to empty the cache. I can tell that the drive light came on for a few megabytes of transfer, and then a long long wait to complete the write. I was sending a 350meg file to the drive.
I read elsewhere about the journal file created to support ext4 being the cause of the slowdown. Anyone else experience this problem. The same drive on a CENTOS system which knows ext3 as the latest file structure shows no abnormal slowdown. Is it possible that it is the schedular that tries to be fair? I tried to renice the writing, and that changed the priority of the task, but did not remedy the problem. Frustrating to not be able to figure out where the jamming is occurring. ------------------ Regards Leslie Mr. Leslie Satenstein
