I bought a couple of these approximately 8 months ago. I needed a way to securely store important network information etc. on a jump drive and have it available on location.My main conern was the longevity of these units. I was worried about the two piece construction with the cable between them. My concerns have been justified. We are having problem with the cable connection on the units and must jiggle the pieces around because the connection is intermittent. The two piece contsruction with the cable between is clumsy design and I expected more from SanDisk.
