Specifications, Pricing and Availability
Today we're looking at two of the three Neutron drives offered by Corsair. The company also has a 64GB model in the base Neutron, a capacity size not offered in the flagship Neutron GTX. Here we see spec sheet for the two Neutron products we're testing today. The 128GB is on the left and the 256GB on the right.
Let's roll through the 128GB model first. The 128GB capacity size reads sequential data at 540MB/s and writes sequential data at 211MB/s. We didn't test the original Neutron 120GB drive so this is our first look at the 128GB class product. 4K random write I/OPS comes in at 51K I/OPS, Corsair doesn't list read I/OPS, but Newegg lists 51K I/OPS.
The 256GB class Neutron will be the main focus of today's article, but we're rolling the 128GB performance numbers in as well. We reviewed the 240GB model with IMFT less than a year ago. The specs have changed and for the better with this capacity size.
Starting with the big change, sequential write performance is now at 450MB/s, up from 370MB/s on the 240GB original drive. This falls in line with the write performance increase we observed on the SK Hynix branded, SandForce controlled product we tested several months ago. Hynix flash, we don't see it often, but so far the results have been positive.
In the time between our purchase and writing this article, the Neutron prices have increased at Newegg. We paid right around $170 for the Neutron 256GB and the price was $199 at the time of writing. Newegg does have Neutron 240GB drives in stock at $169 and I'd suspect the new model price was increased to clear out the older 240GB drives.
The Neutron 128GB is also at Newegg for $119 at the time of writing. This is only five dollars less than the Neutron GTX 120GB. We'll put these two drives head to head soon in the new Neutron GTX 120GB, 240GB and 480GB article.
Corsair ships Neutron with a desktop adapter bracket, screws and a paper manual. Neutron is the only mainstream SSD in a two tier system that ships with a five year warranty.
