Performance
Performance has been tested on an Intel Haswell-E platform which contains i7 5820K processor and ASUS Rampage V Extreme motherboard. For all tests were used Intel USB 3.0 ports.
As usual, we will start from ATTO Disk Benchmark as it’s one of the most popular storage benchmarks on the market.
ATTO is showing a bit low read bandwidth which in this case tops at about 125MB/s. We were expecting at least 15-20MB/s more. On the other hand write bandwidth is higher than expected and it’s about 100MB/s.
I’m not sure why but similar situation in ATTO was in last Lexar review where we were testing SDHC/XC card. The same as in last case, I will try to perform additional tests on other platforms and report back if performance will be better.
USB storage performance highly depends on used controller and drivers but in this case is the latest version of the driver and controller had no problems to pass 400MB/s on other flash drives.
CrystalDiskMark is showing better results. We could achieve up to 148MB/s so I guess it’s what we were expecting. The same as in ATTO maximum write bandwidth is near 100MB/s what is also pretty good.
At the end Anvil’s Storage Utilities where we back to read bandwidth seen in ATTO. 128MB/s is still good result but could be a bit better. Depends on used test, performance is lower or higher and that’s normal. Especialy in Anvil’s benchmarks we usually see lower bandwidth so we are used to that.
Lexar JumpDrive S57 is performing well. We were able to reach about as high bandwidth as Lexar is declaring but only in CrystalDiskMark. It’s still not bad as no one is guaranteeing constant 150MB/s. Write bandwidth on the other hand in all nearly tests was near 100MB/s what is good result for a flash drive.
I guess that all who decide on this flash drive will be satisfied.
