SMI Samples First SD Express Memory Card with SMI SM2708 Controller – Benched at 900MB/s

CRYSTAL DISK INFO VER. 8.11.2 X64

Crystal Disk Info is a great tool for displaying the characteristics and health of storage devices. It displays everything from temperatures, the number of hours the device has been powered, and even to the extent of informing you of the firmware of the device.

Checking Crystal Disk Info, we can see our sample SD Express card containing the SMI SM 2708 controller is utilizing the NVMe 1.3 protocol and has features to include SMART, TRIM and VWC.

ATTO DISK BENCHMARK VER. 4.01

ATTO Disk Benchmark is perhaps one of the oldest benchmarks going and is definitely the main staple for manufacturer performance specifications. ATTO uses RAW or compressible data and, for our benchmarks, we use a set length of 256mb and test both the read and write performance of various transfer sizes ranging from 0.5 to 8192kb. Manufacturers prefer this method of testing as it deals with raw (compressible) data rather than random (includes incompressible data) which, although more realistic, results in lower performance results.

Initial performance highs in ATTO are 857MB/s read and 394MB/s write data transfer speeds.  We spoke with Silicon Motion with respect to the write performance being less than half of that expected and were informed that it was because of the 2-plane flash and our results were within their expectations.  With adaption and availability of 4-plane NAND flash memory, performance should just below 1GB/s.

CRYSTAL DISK BENCHMARK VER. 8.0.1 x64

Crystal Disk Benchmark is used to measure read and write performance through sampling of random data which is, for the most part, incompressible. Performance is virtually identical, regardless of data sample so we have included only that using random data samples.

THROUGHPUT

IOPS

ANVIL STORAGE UTILITIES PROFESSIONAL

Anvil’s Storage Utilities (ASU) are the most complete test bed available for the solid state drive today. The benchmark displays test results for, not only throughput but also, IOPS and Disk Access Times. Not only does it have a preset SSD benchmark, but also, it has included such things as endurance testing and threaded I/O read, write and mixed tests, all of which are very simple to understand and use in our benchmark testing.

TxBENCH

TxBench is one of our newly discovered benchmarks that we works much the same as Crystal Diskmark, but with several other features. Advanced load benchmarking can be configured, as well as full drive information and data erasing via secure erase, enhanced secure erase, TRIM and overwriting.
