- Very slow PNY Attache USB 2.0 flash drive

claiming to be USB 2.0. To copy 7 mp3 files, 25.5 MB, from my hard drive
to the PNY drive takes 67 seconds; to the RiData takes only five
seconds. For both tests, the drives were plugged into the same USB
socket on the front of my computer. Neither had any other files on them
before I timed the transfers.
Any ideas why the PNY drive is so slooow?
Re: Very slow PNY Attache USB 2.0 flash drive
Besides the generally poor performance of low priced flash drives there are
other things that affect performance. I have a 1 GB drive that has slightly
better write speed with big files when caching is turned on, but when backing up
a large number of smaller files the speed drops to about 100 KB/sec. With write
cache turned off it is a more acceptable 1.5 MB/sec; still only about 1/3 the
speed writing a large file with write cache on.
