Apple store only has the 1tb version. lacie has a 128gb ssd a 256gb ssd and the 1tb hdd . they have both cables usb3 and t-bolt. the 128gb ssd is 199 the 256gb ssd is 349 the 1tb hdd is 249 lacie has all 3 in stock http://www.lacie.com/products/product.htm?id=10599 apple had just the 1tb hdd in stock http://store.apple.com/us/product/HA384ZM/A/lacie-1tb-rugged-usb-30-thunderbolt-series-hard-drive I will tear my open and drop in a few ssds. I have a samsung a mushkin a crucial and an intel . If I remember this case is easy to open. But with free cables it is a big price drop. consider a 256gb ssd for 349.00 all included. The seagate is about 85 if you are lucky a cable is 45 that is 130 and on sale a 256gb ssd is 180 comes to 310 and no usb3. So when the 256gb comes out it may be worth getting.
