We all use them so I was wondering if there is any preferance on what to get. For my Roland BK9 32g is the max. The ones I have are dated and when I backup to my computer or other USBs there seems to be changes in settings. I've seen that SLC drives are the best kind but expensive. Any suggestions?

I usually use Sandisk brand, can't go wrong with them. Currently I'm using a PNY 32GB on my SX-900. Works great. No problem backing up with either to a computer. Unlike a camera, or camcorder, I really don't think a keyboard needs a high end, high speed USB storage.

I use a very small San Disc 32gb Cruzer. It performs very well on keyboard and PC. It is small enough to keep it inserted while transporting the KB, thus eliminating frequent removal and insert which could damage the USB input terminal.

I use Sandisk Cruzer 16GB & 32GB they work good on SX-900

SanDisk and Kingston is among my all time favourites.
At BK9, I did use a mini version very lookalike SanDisk Ultra Fit 32GB.

Thanks guys Looks like the name brands win.
