Performance
Performance has been tested on the USB 3.0 controller built-in ASUS Rampage V Extreme motherboard. It’s new and fast but also quite popular platform so all our readers can compare results without bigger problems. Similar performance should provide other new laptops and desktops based on Intel chipsets.
ATTO Disk Benchmark
Lexar declared maximum bandwidth is up to 300MB/s and actually we have similar numbers. Looking at the results in ATTO I’m more than satisfied. Nearly 300MB/s read and over 250MB/s write is a great bandwidth, higher even than earlier generations of SSD.
CrystalDiskMark 3.0.3 x64
Random transfers are not so important for SD cards but I wanted to see how fast can run Lexar SDXC card in CrystalDiskMark which is one of the most popular storage benchmarks.
Sequential transfers are similar to what we could see in ATTO while random are simply amazing for a SD card. Over 14MB/s in 4K random read is really high for so small device. It really starts to look good when you compare it to popular drives which you can find your computers. 14MB/s is about 50% of new SATA SSD speed and about 5-7 times more than a regular HDD can reach.
Anvil’s Storage Utilities
Next benchmark on our list is Anvil’s Storage Utilities. It’s showing us about the same as CrystalDiskMark but it using different test file sizes. Also here results are great, especially in read bandwidth.
There were no issues during longer tests too so we can be sure that Lexar 2000x is stable and offers consistant performance regardless how long are you using it.
PCMark8
PCMark8 is not a benchmark which we are usually using to test flash cards performance. However in this case I was really curious how Lexar Professional 2000x will perform in this high demanding test.
As we see results are not really high but considering it was made on a SDXC card it’s pretty amazing. Results are much better than for popular HDD. We could probably keep good performance even if we tried to run operating system from this card but I’m not sure how long it would work as it’s not designed for these purposes.
