Desktop Test System no. 2




Drive Properties




The majority of our testing will be done with our test drive/array as our OS volume. Our boot volume is 75% full for all OS Disk "C" drive testing, to mimic a typical consumer OS volume implementation. We're using 64K stripes for all of our arrays. Write caching is enabled.


Our testing includes charting the performance of a single drive, as well as a RAID 0 array of our test subject/s. We are utilizing Windows 8.1 64 Bit OS for all of our testing.



ATTO Baseline Performance


Version and / or Patch Used: 2.47


ATTO is a timeless benchmark used to provide manufacturers with data used for marketing storage products.




Transfers are excellent, ramping up quickly, and staying strong throughout. All transfers are occurring within the EVO's Turbo Write emulated SLC write acceleration layer, so they look fantastic. Both read and write speeds exceed 1GB/s.


Sequential Write




Equipped with a larger ratio of DRAM buffer, the 250GB mSATA EVO manages to outperform the larger 500GB standard SATA interfaced EVO array, and takes the win in this test.


Sequential Read




Read performance is excellent, hanging right in the mix of the best performances on our chart. Single drive performance is also outstanding.
