Lexar JumpDrive S25 128GB and S45 64GB Flash Drives Review

Performance

Performance has been tested on a Dell Latitude E5570 based on Intel i5 6440HQ processor and Intel HM170 chipset. Used USB 3.0 ports were connected to Intel controller.

Specification isn’t anything unusual and all our readers can easily compare results to what they can achieve on their home computers.

It’s time to start with the tests and as usual at the beginning will be ATTO. All results on the left side were made on JumpDrive S45 while all on the right on the S25.

As we see on above screenshot, both flash drives have much higher write bandwidth than declared while read bandwidth in ATTO benchmark is lower than expected. Bandwidth depends from additional factors and I think that 135-140MB/s read in both cases is still pretty good. Write however surprised me. I was expecting 45MB/s while results are twice as good. JumpDrive S45 went up to 118MB/s while S25 passed 82MB/s.

Let’s take a look what results are in CrystalDiskMark. The same as before left is JumpDrive S45 while right is S25.

Both flash drives are performing almost the same. There are a bit faster or slower parts but in general we can count on similar experience while work with both of them. In CrystalDiskMark we could see that test results on larger files were better. Depends from run, both flash drives ( even though you can’t see it on above screenshots ) were reaching declared speed of 150MB/s read and 45MB/s write. It’s maximum speed which depends from many factors so we can’t count we will see it all the time. Overall results are pretty good and most of the results are repetable what tells us there is no problem with stability.

Last test is Anvil’s Storage Utilities so something like tests above with couple of additional results. On the first screenshot are results made on JumpDrive S45 and on the second are these made on JumpDrive S25.

As we see, depends from benchmark and used test files results are changing but are still quite consistent. It’s also first test where we can see that S45 results are slightly below declared ( including writes ). It’s not a big issue as in this benchmark most drives are showing lower than expected results. S25 on the other hand is keeping quite good performance also in Anvil’s benchmark.

One more photo at the end as I really like these small flash drives.
