Testing – HDTune Pro & ATTO
Keep in mind for testing the advertised speeds for this drive are 550 MB/s read and 160 MB/s write.
HD Tune Pro is one of the most popular hard drive software suites available. It has many different benchmarks and tests built into it. The benchmark that we mainly focus on is the file benchmark. It has two separate tests. The first tests a file size (500MB for our test) and gives you sequential read and write speeds. It also gives you IOPS for 4KB random single and 4K random multi.
Here we can see some really good results, a little short of the advertised speeds though. The second test in the File Benchmark is a file transfer test with different sized files.
ATTO Disk Benchmark also measures transfer rates across specific lengths. ATTO uses RAW data, our transfer sizes ranged from 0.5 to 8192kb. ATTO is usually our definitive benchmark for solid state drives.
Here the drives performs right up to its specifications. Here is ATTO results compared to some of the more recent drives that we have tested.
While the read score sits at the top of our results with other Phison S10-based drives, the write score is the worst out of the group. This is because we are testing the 120GB version of the drive. Solid state drive controllers achieve peak performance by addressing multiple dies at the same time, but the smaller capacity drives do not have enough NAND chips for this to work correctly. The 240GB and 480GB versions of this drive have advertised write speeds of 320 MB/s and 530 MB/s respectively.
