Corsair Neutron & Neutron GTX: All Capacities Tested
by Kristian Vättö on December 19, 2012 1:10 PM ESTPerformance vs. Transfer Size
ATTO is handy tool for measuring sequential IO performance at varying transfer sizes. To keep the graphs somewhat readable, I didn't include all possible drives but for specific comparison you can always use our Bench tool. Sequential read performance at small transfer sizes is an area that many of the newer SSDs have been neglecting, the Neutron being one of them. Especially IO sizes of 4KB and 8KB are common in client workloads, so I'm hoping LAMD and Corsair can improve the performance at those transfer sizes in a future firmware update as the gap between the Neutron and other higher-end SSDs is fairly significant.

Write performance isn't as bad, although there is definitely room for improvement at the smallest transfer sizes. Client workloads rarely see IO sizes below 4KB, meaning that there is little to no impact on real world performance unless we talk about some very specific workload. At the most important IO sizes, Neutron's write speed is on par with other drives.

Always glad to see someone step in with a different controller than the majority have, and see it perform very well. Good job Corsair!I have to say, the price/performance is excellent and I'm very tempted to replace the 840 Pro as the choice for my next build. That being said, what I really hope it does at this point is cause Samsung to drop the price of the 840 Pro lineup.

I wouldn't expect much of any change-up in the market as these drives have already been out for a few months. They are not brand new at this point.Sabresiberian - Thursday, December 20, 2012 - link
Heh well I wasn't implying there would or even should be any kind of change-up, I'm just saying I want competition to stay alive as long as possible, and if everyone jumps onto one controller from one source the only competition point will more rapidly come down to just price.The differences are basically controller, NAND, and price, in today's consumer market, and frankly I'd like to see controllers in particular get a lot better. They are good at pumping out high peak numbers, but consistency and even reliability just aren't there yet, in my opinion. (I mean reliability in terms of getting a bug-free controller, not in terms of life of the SSD.)

Hmmm...The Samsung 840 Pro 512GB has dropped by at least $100 in the past month. Not making any claims about the reason for that.Drazick - Wednesday, December 19, 2012 - link
Hi,Why don't you update your Google+ Page?
Thank You.

What's Google+?Snotling - Thursday, December 20, 2012 - link
google it, you'll know.Sabresiberian - Thursday, December 20, 2012 - link
Google+ is an even less secure version of Facebook.If you like Google laying claim to every word you say, then by all means sign up for it.

When are you going to review lower capacity models of 840 Pro and 840?Nice review though.

I have a 128GB and 512GB 840 Pros but we are still waiting for additional 840 capacities.
