Lexar Professional 1800x microSDXC UHS-II (64GB) Review

THE SSD REVIEW TESTING PROTOCOL

At The SSD Review, we test our storage devices slightly different depending upon the device’s marketed purpose.  Our goal is to test in a system that has been optimized with our SSD Optimization Guide, however CPU C State alteration may or may not have occurred depending on the motherboard and BIOS configurations. Benchmarks for our tests are that of fresh devices, so that we can verify that the manufacturer’s specifications match the device. Additionally, we also try to include links to the benchmarks used in our report so that you as the reader can replicate our tests to confirm that your device is top-notch.

BENCHMARK SOFTWARE

The software in use for today’s analysis is typical of many of our reviews and consists of Piriform Speccy, ATTO Disk Benchmark, Crystal Disk Mark, AS SSD and Anvil’s Storage Utilities. We prefer to test with easily accessible software that the consumer can obtain, and in many cases, we even provide links. Our selection of software allows each to build on the last and to provide validation to results already obtained.

PIRIFORM SPECCY

Piriform Speccy is a great tool for checking the status and health of your computer system. It provides you with brief summary, or a detailed look, at your operating system, CPU, RAM, motherboard, graphics, storage, optical drives, audio, peripherals and network.

Lexar 1800x micro SDXC testing 1

As we can see the Lexar microSDXC card is formatted in exFAT, has a real size of 64GB, but a total usable capacity of 59GB, and it does not support SMART attributes, which is common for SD cards and USB devices.

ATTO DISK BENCHMARK VER. 3.05

ATTO Disk Benchmark is a relatively easy-to-use benchmark tool, which happens to be the benchmark of choice for many manufacturers. ATTO uses compressible data rather than random data, which results in higher performance and thus, higher benchmark scores. In our testing, we have selected the transfer size to range from 0.5KB to 64MB, and have set the total length of the test to be 256MB.

With our first test, ATTO returns some interesting results. While the read speeds come in anywhere from 30-40MB/s under the listed specifications, the write speeds come in even lower by 60-70MB/s.

most cameras and other dont have UHS-II support. it requires extra interface, so the card is limited to UHS-I in moost appication and this is limited to about 100mb/s .You should rather test this cared against other in high end camera not in windows stupid tools

Woah, those are some pretty expensive cards.

I wish manufacturers would make cards, tuned for random performance. With lots of single board computers floating around without any nand storage, cards like this would be great.

Instead of crazy 100MB/s+ sequential speed, tune the card for low QD at the expense of sequential performance. i’m sure it can be done.
