Hi there! i use about a year ago, only ssd drives at the cdj's and i can only recommend them. No errors at all, very fast at exporting tracks and no delay-lag at loading tracks on the (4)cdj's. I use: intel ssd 320 series with a 2.5'' external usb 3 case. You should look up for the connector of the drive you wanna buy, because the usb3 connector's are most all of them like the one you show in this link, and they are very fragile. I found a case that is usb3 but have the "old" classic usb connector (with double cable for usb3 power). Try to found something like that.
