We use AS SSD to assess the drive’s performance at dealing with incompressible data. Since the 850 EVO does not invoke any data compression like the SandForce drives, we should expect the result to be similar to what we have observed.
Good start with the sequential read.
No surprise here with the random write where the drive performs well at low queue but high queue is suffered by the lack of parallelism.
Looks like AS SSD’s test does not give the drive long enough time to enter the non-TurboWrite mode which results in a very competitive sequential write performance.
The 120GB 850 EVO scored 5553 point in the PCMark 7 storage test. It has out-performs many of the 256GB drives. With RAPID, we get 6060 points, or 9% improvement in the performance.
Individual tests show that the 850 EVO is taking the top spot in almost every single test. With RAPID enabled, we get about 1-10% depending on the type of workloads. Tests where involved disk writes such as Video Editing and Importing Pictures often shows higher improvement. Application Load test in particular shows 46% improvement.
