Corsair Neutron Series SSDs employ professional-grade LAMD SSD controllers to deliver strong overall storage performance without tradeoffs. They offer impressive performance, even with compressed and non-compressible data. With a 2.5-inch standard form factor and only 7 inches tall, they can fit any systems which support a 2.5-inch drive. The 2.5- to 3.5-inch adapter offers compatibility with desktop PCs.

  • newegg Serious Real-World Performance The Link_A_Media (LAMD) controller delivers both super-high IOPs — important for data-intensive tasks like video and image editing — and superior sequential read speeds for lighting fast file access. Neutron’s real-world performance design focus means impressive file loading times, even with non-compressible data. You can count on the performance and speed no matter what type of work you do on your PC.
  • newegg Install It Almost Anywhere Neutron Series SSDs follows the universal 2.5-inch standard, and snaps into place on most notebooks. They are just 7mm high, so they can be installed even in many of the latest slim designs that have additional space restrictions. An adapter is included for wide desktop PC support.
  • newegg Built for SATA 3 6Gbps The Neutron Series is designed to support the latest high-speed standards to get the most performance out of the latest PCs. It's also fully backward compatible with SATA 2.
  • newegg Cool and Quiet, with Low Power Consumption Traditional mechanical hard drives spin at thousands of revolutions per minute. This takes power, and generates noise and heat. Since SSDs have no moving parts, there's no noise or vibration, and the lower power consumption helps keep things cool inside your PC. It can also save the battery life on notebooks.

1 out of 5 eggsComplete GARBAGE

Pros: None. I cant think of a single good thing about this drive.

Cons: We have purchased over 10 for customers builds and have had 4 start giving S.M.A.R.T errors and then fail to boot a few days afterwards. Almost 50% failure rate is no acceptable! I have several Samsung and Intel SSD's out in the field and have yet to have one fail.

Other Thoughts: Buy another brand, the Neutron series is sub par at best.

Manufacturer Response:

3 out of 5 eggsGOOD PRICE

Pros: decent price for name brand 64BG SSD.
some SSD's were cheaper but decided to go with corsair, this is my 1st corsair purchase of any hardware.
did not have to move anything in pc case to install.

Cons: only using on P45 mobo now, but this is intended for next build so can't really rate it yet so that's why 3 eggs.
was not free

Other Thoughts: i enabled AHCI in the bios, SSD shows up in the disk boot priority of the bios with linux.

4 out of 5 eggsFast, works, but has one issue...

Pros: I have my OS, most of my drivers, start-up apps, and my web browser on the SSD. With all of that, my computer boots up in under 10-15 seconds.
Bought this SSD for $85 total; tax included, and free shipping; took 4 days to get to me, so not too bad in wait time.
This is my first SSD; so it's super fast for me coming from a HDD all my life.

Cons: The only issue that I REALLY seem to have is that, 10GBs are just, missing. Before I installed everything, it only had 54GB of free space. Though, at some point during my installation of programs and the OS, I suddenly gained 10GB from out of the blue. Not sure if it was the software problem or the SSD, but ehhh~~ a bit sketchy on that.

Other Thoughts: The con, to me, is a big issue since the SSD isn't very big and im already down to 25GB of free space after installing everything that needed to be on the SSD. Although, aside from that, this is a very awesome SSD that I nabbed at a sweet price.

5 out of 5 eggsGreat Drive

Pros: Standard SSD Perks

Cons: None

Other Thoughts: Purchased 8 of these with 8 new Dell Vostros desktops for upgrades at work. Imaging and OS installation took less than 10 minutes, driver installation only took five minutes longer. Each machine took less than a total of 30 minutes to take apart, install drive, install OS, drivers, applications, and make OS registry edits to account for SSDs (Win7, not 8).

This was a month ago, so far we've had no issues. Purchased the larger drive for my personal laptop and it's never been quicker. Strongly recommend these SSDs if you don't need much local storage.

5 out of 5 eggsGreat little SSD, at the right price

Pros: Fast

Cons: none

Other Thoughts: At the right price, this is a good buy for budget builds. Picked up a few of these at close to 86 cents per gig. Hopefully they stand the test of time. I don't think they are economical at the retail price as you can get double the space for about the same price.

Cons: none

5 out of 5 eggsAdd on from below

Pros: Didn't mention the high marks were from there being NOTHING bad to report about this SSD. I did not have one problem with installing or putting the Win7 64bit OS on the SSD.

It is very small drive, one of the 7mm class of thin ones. But it worked well in a pop out drive holder for hot swapping, tho I aint gonna test that. Don't need to temp fate.

Just have to look up a few articles about them but mainly, if you are using Win7 or above, just make sure you have enabled ACHI in SATA ports. That and tell the BIOS or UEFI that it is a SSD, Win7 does the rest, enables TRIM and all.

Cons: There really were none with this install of this SSD. I was real happy with it.

Seems fasty too, though I don't think most people can tell one SSD speed from another unless they are running huge programs like video and animation rendering or transfering 200 Gigabytes at a time.

But you can tell from a regular hard drive, unless it is just surfing the web, cause there you are limited by your download speed.

It is very snappy, and I was using a Velociraptor hard drive before, so there ya go.

Other Thoughts: I have no qualms recommending this SSD with the experience I have had with it so far, and will update if I find a disadvantage.

5 out of 5 eggsPut in Win 7 64bit new build

Pros: This is the first SSD drive I have used or installed. It is great. I never used one before because of the all of the hassle of setup and config for Win XP. Now that I use Win 7, things couldn't be much easier.

All you have to do is make sure your in the right Sata 3 port for booting from, and make darn sure you engage ACHI in Bios for SATA 3 ports, and install windows. There are some optimizations you can do, such as putting slow stuff like MP3s, movies, pictures, from the My Your Name folders into a regular drive, especially if you are using this small of a SSD drive.

I had only 20GB of space left after installing Win7 and all of the chipset drivers on a brand new ASrock Z77 Extreme 4 motherboard. So it used about 40GB for the OS stuff. I would use the rest for a cache I suppose.

I had already purchased a 250GB Samsung 840 drive to use as my main C drive, but used this one instead for purposes of testing how easily they are to put in. EASY PEASY, NICE AND EASY.

No joke, there is literally not much to it. You just make sure you stick it into a SATA 3 port, set the SATA to AHCI and Win7 will install everything for you like TRIM and the other special things that were haunting me till now. OH, you have to change the drive status to SSD from rotator, easy enough for the particular Motherboard I was using.

Cons: Size and price probably would be the main ones.

Don't worry so much about speed, as long as it is in the main grouping of the reliable SSDs, it is MUCH faster and snappier than any regular hard drive.

IF you have a SATA I or II controller setups for your ports in your motherboard, IT could be advantagous to invest into a add on controller, IF it has access to ports with speeds faster than your SSD, like some use limited ports such as PCI on the motherboard to get the info into database.

If you are a regular user, I would look for reliability of the brand and whether the manufacturer makes its own memory and driver circuits.

I like Samsung, but there are a bunch out there including Intel and Crucial, tho I have a good memory of Corsair always providing me with value memory in the past. In fact, I have more Corsair memory than any other, come to think of it.

OH, and also the most CON thing, you can only write so many times to each memory cell. YEAH.

So pay attention to the articles you should read up on about reducing the accessing the memory, like eliminating defragmentation, and some other programs that are useless for SSDs and make them wear out sooner. Win7 will eliminate most of them after you tell it you are using a SSD drive.

Tom's Hard has some very good articles about alieving tension in installing SSDs and optimizinng them, even for WinXP, it is not as hard as it seems from the hype.

I have found that my SSD from Samsung has the disadvantage of using a circuit that wears out about 1/3 faster than most, but even then, it would take about 8 years of my type of use to wear it out, so for me, it is a nonstarter for prob. The price per GB and Brand made the difference for me.

Other Thoughts: My new clean puter with nothing on it but Win7 and the chipset drivers took 18 seconds to boot, from pushing the on button to the little music introducing Windows. That is without any customizing with FAST themed start up programs that there are a load of in the motherboard BIOS.

Course there were no other programs littering up the Start program, heh.

5 out of 5 eggsReliable mid-range SSD

Pros: This Corsair Neutron comes with a 5-year warranty, but I doubt you'll need it. Corsair has had an excellent track record with reliability and their customer service is both prompt and forgiving if you do happen to get a bad egg.

While it's not the fastest drive out there, the Neutron still delivers. It's a thin, mundane-looking, and nearly weightless drive, functioning well as both an external drive via USB or as an internal drive. Write speeds are identical using USB 3.0 or SATA 3.0. The packaging also includes a 3.5" to 2.5" metal drive bay adapter and mounting screws. With its storage capacity and small size, this model is probably best relegated to ultra-portables.

Access times in HD Tune are excellent for a mid-range SSD at 0.05 ms for both read and write, around the same as the OCZ Octane and the Samsung 830 series. This translates to a drive that can open large programs with scattered data (i.e. Photoshop, a game, or your O/S) very, very rapidly, especially compared to HDD's which tend to have 12ms or higher response times.

Burst rates are fairly average for a mid-range SSD, marginally faster than the Octane and the Crucial M4. However, the Samsung 830 series has burst rates 2-3 times faster according to HD Tune.

CPU usage was surprisingly low, less than any of the other drives I own, which is a definite bonus especially if you're using this with an ultra-portable.

Cons: Unfortunately, the Neutron does lag behind the competition in transfer rates, landing at the bottom of the heap with a measly 283 MB/s write and 420 MB/s read in HD Tune Pro. While those write speeds compare to older SSD's such as the Crucial M4, the Samsung 830 series and the OCZ Octane both blow the Neutron away by close to 100 MB/s write and 60 MB/s read.

This drive could also be a bit more energy efficient, but that's a minor qualm. SSD's consume very little energy as is.

Other Thoughts: All in all, the Neutron is neither a bad SSD nor a standout. I'd have no difficulty recommending this particular model if only it were at a better price point. As is, older offerings from Samsung are both cheaper and substantially faster, so I'd have to recommend drives such as the 830 series over this one. That is, if you can find them. Even Corsair's own offerings, such as the GT series, offer substantially better performance and price per GB.

4 out of 5 eggsSlim SSD drive

Pros: This nice drive for boot drive for server that doesn't need much space as primary OS. Works great on Windows's server 2008 boots up about twice as fast as my original old 7200 rpm drive. Corsair made pretty universal fit any slim portable laptops or desktops with there 3.5' hard drive adapter. Also offer 5 yr warranty. Low power consumption over conventional hard drive . Make nice drives for portable laptops as they have no moving parts in them.

Cons: Not very much space for even as a boot drive as it don't leave you with much space for applications. With only 64 gb drive fully shows on Mac OS X and Windows initialize as 59.63 that pretty small with today's OS and basic applications.

Other Thoughts: I've found that you usually can get about twice speed from a solid state drive over a conventional 5400 and 7200 rpm drive. I have found though even with no moving parts that SSD drive can still fail and when they do it make it pretty hard to recovery any data over a conventional so I'd strongly recommend to still always backup your data and not rely on it not to fail cause still possible.
