Crucial MX300 1050GB and 2050GB SATA III SSD Review

Iometer – Maximum IOPS

 

Version and / or Patch Used: Iometer 2014

 

We use Iometer to measure high queue depth performance. (No Partition)

 

Max IOPS Read

Max IOPS Write

Both capacity points meet or exceed factory specs. The MX300 is able to sustain high write IOPS for the entire 30 seconds of our test, which is something planar-based TLC SSDs like the WD Blue cannot do.

 

 

Iometer – Disk Response

 

Version and / or Patch Used: Iometer 2014

 

We use Iometer to measure disk response times. Disk response times are measured at an industry accepted standard of 4K QD1 for both write and read. Each test runs twice for 30 seconds consecutively, with a 5-second ramp-up before each test. We partition the drive/array as a secondary device for this testing.

Being write-centric, this plays out as we would expect to see. Excellent write response, below average read response.

 

 

DiskBench - Directory Copy

 

Version and / or Patch Used: 2.6.2.0

 

We use DiskBench to time a 28.6GB block (9,882 files in 1,247 folders) composed primarily of incompressible sequential and random data as it's transferred from our DC P3700 PCIe NVME SSD to our test drive. We then read from a 6GB zip file that's part of our 28.6GB data block to determine the test drive's read transfer rate. Our system is restarted before the read test to clear any cached data, ensuring an accurate test result.

After we upgraded to Windows 10 Anniversary edition, sustained write performance took a massive leap for the better. We cannot compare our results as measured on the previous version of Windows 10. Because of this, we only have two SSDs for direct comparison that were also tested with Windows 10 Anniversary edition.

 

If we compare the write transfer speed of the planar TLC-based WB Blue to the MX300, we can clearly see one of the advantages that 3D TLC has over planar TLC – sustained write performance. The WD Blue is the perfect comparison because it uses the same Marvell 88SS1074 controller as the MX300.
