The M500 package follows the other Crucial SSD product packages. We received the drive only kit, but Crucial will have other kits available for specific applications.
Inside the box we found the M500 drive and a new accessory from Crucial, a 7mm to 9.5mm adapter. The adapter has two double-sided tape sections so you can quickly attach the bracket if you need it.
There aren't very many systems that would need the adapter put on, but if you need it, you'll be happy Crucial included one.
