Silicon Power Bolt B75 Ultra-Thin Portable SSD Review
 

As the Armor A75, the Bolt B75 does feature a military-grade shockproof casing that is quite light and also acts as a heatsink for the internal SSD. Being based on a SATA 6Gb/s internal SSD interface, the drive is limited a bit in terms of reads/writes, even before the cache fills up, but for regular backup tasks that do not involve usage of very big files, this should be a non-issue.
