What customers say about "Size & Weight"
Lexar JumpDrive S45 USB 3.0 Flash Drive
  • The small size is extremely convenient.
  • Other than that, for the size, price, and memory capacity, it's not a bad buy.
  • I like the compact size; I could travel with it installed and it operated as expected.
  • Exactly what I was looking for - perfect design to keep a high capacity flash drive on my key chain.
  • Granted, the size is why I bought them...but it would be nice to have a small wrist strap at the end to pull them out of the computer and keep track of easier.
  • The size is convenient but until they figure out how to keep it from over heating I do not recommend it.
  • Considering the size, it can be easily lost, but the advantage is it can be left in a laptop with little risk of it being bent or otherwise damaged.

What customers say about "Features"
Lexar JumpDrive S45 USB 3.0 Flash Drive
  • This usb is has been great. I use it as a external hardrive to expand my laptops memory capacity.
  • I love the size and the fact that it has such a high capacity.
  • Fast USB 3.0. Inexpensive for what you get.
  • Very fast read/write speeds. Good price. Use it to backup data with encryption.
  • It's probably secure enough for general consumer use, and is certainly a convenience making it easy to protect your data.
  • The only thing I don't like is that the hole to add the keychain is on the little plastic top not on the actual Flash Drive. Other than that it's perfect.
Lexar JumpDrive S75 32GB USB 3.0 Flash Drive
  • The advertised write and read speeds are "up to" 60 MB/s and 150 MBps, respectively, and it is pretty close to this.
  • I don't use the encryption software but I guess it's good to have if I need to protect sensitive data.
  • I performed Crystaldiskmark tests for one of these flash drives and the results are good, almost as advertised.
  • Copies decently fast and 32Gb capacity is well enough.
  • The Lexar S75 writes very slowly at only 1/2 of USB 2.0 speeds (13.5Mb/s).
