On the Lexar website they claim read and write speeds of up to 450 MB/s for the 128GB version of the drive. To test this we ran a few different benchmarks including CrystalDiskMark, ATTO Disk Benchmark, and the AJA System Test.
As you can see our read speeds were right up to the specifications, but our write speed was much lower, around 350 MB/s. This is sort of expected on USB flash drives so I am unsure as to why both the advertised read and write speeds were the same.
USB flash drives are nothing new, but they definitely still serve a purpose. For most people it is taking files and data back and forth from work, but for others they might have important applications on the drive, or something else. I think the biggest changes we’ve seen in USB flash drives over the past few years is speed. In our testing the Lexar JumpDrive P30 achieves sequential read and write speeds of up to 450 MB/s and 350 MB/s respectively. That is super-fast and will definitely keep those transfer times down to a minimum.
For those looking for some security this drive does offer 256-bit AES encryption through the DataShield application that comes on the drive. So you are able to securely transfer and store files. I also really like that this drive is available in some rather large capacities. We reviewed the 128 GB unit, but you can get it in capacities all the way up to 1TB! That is definitely a lot of storage that you can just throw in your pocket. One last thing about this drive is that it does feel pretty solid in your hand thanks to its metal casing.
