USB 3.0

Lexar advertises speeds of 265 MB/s read and 245 MB/s write, which is noticeably faster than the Triton. The JumpDrive P10 manages to hit 260 MB/s read, which is excellent, in the ATTO benchmark, while its write speed does not quite live up to those Lexar promised; that said, over 200 MB/s at peak is still impressive. Looking at HDTach to see how the flash memory behaves across its entire capacity, it become apparent that Lexar marketing is based on some truth as the JumpDrive P10 nearly hits both values as advertised. However, write speed is, interestingly enough, a lot more consistent, with less fluctuation than read performance. Reading data peaks at nearly 260 MB/s, but hovers between 120-160 MB/s most of the time.

Taking average read and write from HDTach, the results are a bit backward. The more consistent write performance has the drive offer better write than read speed. The JumpDrive P10 should take the throne in comparison to other drives, but its fluctuations place it in the middle of the pack for read speed, even loosing out to the older and lesser-specced Triton. Write speed, even on average, however, is nearly 80 MB/s faster than any USB 3.0 flash drive we had the pleasure of reviewing, basically blowing the competition out of the water.

Turns out, the dips from the drive come from the way that HDTach benchmarks a flash drive. Apparently the P10 drops from user data I/O mode into NAND maintenance mode. This is a phenomenon which is different with every model, so we will be introducing the second benchmark mode of HDTach with this review which shows what the drive is capable if there is no pause in benchmark. As you can see in the image above, with this modus, the drive comes quite close to the advertised performance.

This does not change the fact that other drives perform better in our traditional benchmarks - coming close to the advertised speeds.

USB 2.0

USB 2.0 performance is where you should expect it to be—the JumDrive P10's read speeds push things to the limit, and it offers good write performance; but we would like to see 30+ MB/s write to round out its performance nicely.
