IMHO, the easiest thing to do is to rule out the NTFS filesystem by trying to copy more than 500MB to the encrypted partition (assuming it is not using NTFS). Then, to rule out the encrypted but non-mounted partition by replacing it with a non-NTFS partition or by using another disk with the same layout but a non-encrypted partition.
What can slow down the write access (my impression is that reading is still OK, though I only transferred small files, so I can't say for sure)?
There are some bug reports: * writing to usb flashdisk uses too much cpu and makes system unresponsive[0] * excessive swap out due to compaction/LRU aging[1] And at least two forum threads: *OpenSuse 12.1 freezes while copying data[2] * USB drives bad performance, low speed[3] BTW, only [3] seems to be specific to NTFS whil the other links describe system freezes resulting in slow write performance.
