Regrettably, there's nothing breezy about the performance of the drive. For testing we ran two sets of read and write tests to see how the drive performed with different kinds of files. The first was a simple Large File Test, a single 700MB video file and the other a more demanding Small Files Test, which consisted of just over 1GB of various files including documents, music files, images and plenty besides. Each test was performed three times, with an average time taken from the three and a speed rating (MB/s) derived from it.
In the write tests the Lexar was particularly disappointing, managing just 3.8MB/s in the Large File Test and 1.8MB/s in the Small Files Test. This trailed the Corsair Voyager GT by a massive margin, while also failing to match up to a generic memory key as well.
Things did improve a little in the read tests however, with 18.3MB/s in the Large File Test, while it was the quickest in the Small Files Test with 10.1MB/s. Still, this was the only area where the Lexar won out and even then it wasn't by any great margin. At the very least it means that it's relatively pain free to get lots of documents off the device, though it'll obviously take a good deal more time to get them onto the device in the first place.
Ultimately this lack of overall performance puts into the question the value of this drive. One can certainly get faster drives for less money, which will give more bang for your buck. Moreover, aside from the capacity meter the design is uninspired and not especially sturdy. Its file encryption may be impressive, but that data security isn’t worth much if the drive is damaged somehow.
Though the capacity meter is a nice idea, it's not quite as intuitive as it could be and the overall performance of the Lexar JumpDrive Secure II Plus is hardly breathtaking. Good file encryption software does add something extra, but otherwise this is a fairly ordinary device with a gimmick thrown in for good measure.
