I would like some advice on why this is happening to my USB devices...
I have tried a few USB 2.0 pendrives, FAT32, EXT4, NTFS. All no more than 16 GB big.
Read speeds are fine (25-27MB/s)
Write speeds however...
Start really fast i.e. 50 to 60 MB/s then drops significantly down to 10MB/s before gradually slowing down to 2MB/s and less.
Overall the copy process is extremely slow. 30min for 3 files totalling 4.5GB and even slower for 8,422 php/css/html files totalling 352MB.
Where do I begin? Google and forums yielded no help.
I have run benchmarks since acquiring Windows 7 and various other flash pendrives and HDDs.
There is a significant difference. Windows shows transfer speeds averaging around 80MB/s where as Ubuntu never averages above 11MB/s. Same hardware, same USB ports.
This, along with poor battery life is quite disheartening.
