Cavalry's CAXP series is a line of four portable hard drives and three portable flash drives, intended to satisfy a range of consumer mobile storage needs. Available hard drive capacities are 160, 250, 320, and 500 GB, while the SSD models hold 32, 64, or 128 GB. Each CAXP model can utilize either USB 2.0 or eSATA to transfer data and perform backups. A thin, compact form factor, aluminum case, and shock absorption aim to maximize portability. Cavalry's CAXP series has superseded CAXR, which offered a maximum capacity of 320 GB, with no SSD option.
