Performance
Performance has been measured on a couple of plaforms including ASRock, ASUS and MSI motherboards based on X99, Z170 and HM170 chipsets with Intel and ASMedia USB 3.0/3.1 controllers. Presented results are repetable and screenshots were made on ASUS GL552VW laptop which is using Intel USB 3.0 controller.
Let’s start from probably the most popular benchmark which is ATTO Disk Benchmark.
Even though maximum bandwidth for XQD supposed to be 440MB/s, I couldn’t make it work above about 255MB/s. I’m not sure if it’s the USB 3.0 reader or something else. Used USB 3.0 controller supposed to have bandwidth up to 450MB/s what was previously tested on other Lexar storage devices like mobile SSD.
It’s still great result for a flash card but not as high as I was expecting.
In CrystalDiskMark results are a bit lower and we could see 220MB/s. About the same performance was on all presets but higher test file size was giving better results. It’s visible when we compare 500MiB and 16GiB tests.
General performance is good but writes could be higher.
Anvil’s Storage Utilities is showing us about the same sequential bandwidth as we could see in ATTO. Up to 255MB/s read and 115MB/s write are respectable numbers but as in previous tests we were expecting some more.
I’m not sure what is bottlenecking performance of Lexar XQD 2.0 card but I will for sure find out and let you know. Because of limited access to XQD readers, I have no chance to test it on other sample. I simply don’t believe that real performance would be so far from declared, expecially that most Lexar products are rather showing higher performance than expected. There is also a chance that maximum bandwidth can be achieved on designed for that cameras.
For now we can see that this new standard has potential and is for sure one of the best options for new cameras.
