HD Tune Pro - Sequential Performance

We shouldn't have any issues with the ADATA SP 920 128GB when reading data even with the parallelism issue. The flash is fast enough when reading sequential data to hit the upper limit of SATA 6Gb, but random performance and sequential writes are what we have to really pay attention to.

We can tackle the sequential writes right here and show how important parallelism is. The Crucial M550 128GB uses the same controller and DRAM buffer as the SP920. The difference between these two drives is the flash and possibly the firmware. The SP920 uses 128Gb dies and the M550 uses 64Gb dies, both in 20nm lithography.

 

The M550 128GB averages 317 MB/s sequential write performance, but the SP920 only musters 170 MB/s.

 

HD Tach - Sequential Write Performance after Random Writes

 

Version and / or Patch Used: 3.0.4.0

After a number of random writes, we test the drive with HD Tach to see the sequential read and write performance at 128KB. The sequential write performance drops to just 20 MB/s with dirty flash in some places, and the average drops to just 115 MB/s.
