HD Tune is a Hard Disk utility which has the following functions:
Benchmark: measures the performance
Info: shows detailed information
Health: checks the health status by using SMART
Error Scan: scans the surface for errors
HD Tune Pro gives us accurate read, write and access time results and for the last couple of years has gained popularity amongst reviewers. It is now considered a must have application for storage device testing.
Sequential read performance with compressible data has always been a strong card for SandForce based drives and the ADATA SX900 doesn't break with tradition. We scored an average of 415MB/s with the maximum and minimum speeds very close to the average result.
The write performance is where we noticed issues with the OCZ Vertex 3.20, another SandForce based drive using Intel 20nm flash. At Computex last year we tested early 19nm Toggle and early 20nm IMFT flash and found that 19nm Toggle was much faster across the board. IMFT brought their flash to market several months after Toshiba, but they closed the gap and these two competing technologies are now truly competitive.
The SX900's new firmware, 5.0.7a, looks like it increases performance quite a bit over the initial firmware release for Vertex 3.20.
HD Tach - Sequential Write Performance after Random Writes
The write performance decreases quite a bit after our random tests in HD Tune Pro. Here we see HD Tach run right after several random data tests and the 128KB sequential write speed is down to 286MB/s.
