Generally, the endurance rating increases with capacities, which is exactly the case of the Transcend.

You don't really need this bracket to make the drive work - in most cases you can just leave the drive hanging loose since it doesn't have any moving parts - but it's always good to have your drive mounted tightly inside the computer. The Transcend SSD includes a 3.5-inch bracket which will enable it to fit easily inside most desktop computers. The two versions are essentially the same, including the pricing. Note that Transcend also offers another version, model SSD370, that has plastic casing. The new SSD370S is housed in an aluminum casing that's both light - at just 1.86 ounces (58 grams) - and sturdy. It features the latest SATA 3 6Gbps standard, but will work with previous revision of the SATA standard. The SSD370S is compatible with virtually all consumer applications where a standard SATA hard drive is used. The slimmer profile means it can work in more situations, from desktops to standard laptops, and even some ultrabooks. Like most drives of its type, it comes in a 7mm thickness, slightly thinner than the 9.5mm of a true standard laptop hard drive. The Transcend SSD370S is a standard 2.5-inch internal drive.
