Corsair Neutron GTX 19nm 2013 Edition SSD (120GB, 240GB and 480GB) Review - Benchmarks - Sequential Performance

Corsair Neutron GTX 19nm 2013 Edition SSD (120GB, 240GB and 480GB) Review
Not long ago, we wrote about the Corsair Neutron base model with new 22nm SK Hynix flash. Today Chris walks us through the flagship GTX model that now features new 19nm Toggle flash from Toshiba.

HD Tune is a Hard Disk utility which has the following functions:

 

Benchmark: measures the performance

Info: shows detailed information

Health: checks the health status by using SMART

Error Scan: scans the surface for errors

Temperature display

 

HD Tune Pro gives us accurate read, write and access time results and for the last couple of years has gained popularity amongst reviewers. It is now considered a must have application for storage device testing.

Given what we saw on the previous page, it shouldn't surprise anyone to see all three capacity sizes reading sequential data at the same rate in HD Tune Pro.

The two largest Neutron GTX drives peak at nearly 400MB/s sequential and the 120GB model peaks at just over 300MB/s.

 

 

HD Tach - Sequential Write Performance after Random Writes

In this screenshot, we see the 240GB GTX reading and writing sequential data after some consumer load random reads and writes. The write performance actually drops below 50MB/s at one spot in the test, and as you can see, the levels are all over the place.

 

There is a growing trend of measuring 'write consistency' that blossomed from our Toshiba MK01GRRB/R review last October. The test has been copied by several review sites for both enterprise and consumer storage. It's a valid test for enterprise, but not for consumer SSDs. The reason why is because you will never write a constant stream of data to a consumer SSD that is larger than the capacity size of the drive, not in a consumer environment anyway. On the consumer side, you have small writes followed by garbage collection, wear leveling and TRIM. The performance we show is more representative of actual consumer degradation, than just writing massive amounts of data without giving the SSD time to recover.
