Corsair Neutron & Neutron GTX: All Capacities Tested
by Kristian Vättö on December 19, 2012 1:10 PM ESTPower Consumption
With more NAND, you get higher performance but there are also more dies that require power. The difference isn't substantial when compared to the performance increase, though, because for example the 480GB Neutron GTX draws only ~10% more power under load than the 120GB model. At idle there is essentially no difference between smaller and larger Neutron capacities. For some reason the 240GB Neutron stands out with its surprisingly high power constumption; it's noticeably higher even compared to the 480GB Neutron GTX. Power consumption in general is something I hope LAMD and Corsair can address thorugh a firmware update. Load power consumption is bearable but at idle I don't think any SATA SSD should draw more than 1W, preferably no more than 0.5W.

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.

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.
