Welcome!

SSDMeter is a website collecting information of SSD products. User can select and compare different SSD products in the sidebar. The model name and version of products are listed in the top of the page. We will upgrade SSD products information and test results regularly.

We focus on NVMe SSD products in different form factors, like M.2, AIC, Thunderbolt, and even NVMe over fabrics. We do not gather SATA SSD products.

Software

In order to get the best control and information on NVMe SSD, we use the driver pynvme. It is based on SPDK, so we can get the raw performance of SSD devices, without overhead or cache/buffer in any OS storage stacks. It is a python extension of SPDK, so we can develop test scripts in Python and make use of existed test frameworks and utilities. With Pynvme, we can send and verify different NVMe commands, even those illegel commands. Furthermore, Pynvme verifies data with CRC32, because data integrity is the most important thing for any storage device.

All tests are conducted on the same computer.

Tests

We develop test scripts to collect basic information, NVMe conformance, performance with different workloads, and SSD device reliability. Tests have been developing and conduecting reguarly, and the websites are updated accordingly.
