The Single Best Upgrade for Your PC

With its simple 3-Step migration solution and industry-leading IOPS performance, the Samsung SSD 840 Series is the single best upgrade you can make for your PC. Samsung's new SmartMigration software takes the guesswork and headache out of moving your operating system and precious data to your new SSD. Once you're up and running, the 840 Series' amazing IOPS speeds empower you to multitask like never before.

Upgrading to an SSD is the easiest and most economical way to breathe new life into an aging PC. Today, most PC performance woes are the result of slow read and write speeds on behalf of the main storage device, not a lack of CPU performance. Upgrading to a Samsung SSD 840 Series can breathe new life into your old PC by enhancing boot-up speed, application loading, and multi-tasking performance.

Remarkably fast, cool, and quiet.
Larger capacities command a big premium over HDDs.
I installed one of these in my late 2006 15" MacBook Pro. Prior to this I had the original 120GB 5400rpm, 500GB 5400rpm, then a 500GB 7200rpm Seagate. All three of those drives made the palmrest very hot near the drive where the 840 SSD does not. I also don't miss hearing the spin and seek noises of the platter based disks. Installation was straightforward- I purchased Trim Enabler to set up TRIM and diagnostic functions in Mac OSX. It's at 506 power cycles and 600 hours of operation now with no problems. It sees a fair bit of write access and typically has about 40GB available. My laptop only provides SATA I, so I don't necessarily see the full throughput potential of this drive. Benchmarks show read speeds of 110MB/s and writes of 120MB/s. Boot time is remarkably short- faster than brand new HDD based Macs. Application startup and file operations are snappy too. Spending about $200 on this SSD led me to be satisfied with the performance of my MacBook Pro and has considerably delayed my replacement of it. I will be purchasing more of these or the new 840 Evo for other projects in the future.

Great SSD, best bang for the buck
It may not be as fast as the 840 Pro, which I purchased from NCIX as well, but I agree with other reviews saying this SSD gives the best price to performance ratio. So I've put this one into an older laptop that wouldn't take advantage of the 840 Pro anyway, and the difference between the 5400 RPM HDD that came with the laptop and this SSD is astounding. The Evo will supersede this SSD soon but if you can get it for a deal, go for it.

Amazing cheap and fast SSD
Starts up Windows in ~10 seconds
Doesn't come with mounting hardware
Amazingly fast and was pricematched to $175. Upgraded from an old Western Digital 500gb and it blew my mind when I switched to an SSD.

Fast (for the price), reasonably inexpensive, slim, good looking
Not as fast as the pro series
The Wirecutter recommends this drive as the best SSD for most, and for good reason. It's reliable, the best performer in its price class, and works perfectly.
For a fair bit more money you can shell out for a pro version which offers faster write speeds, but most people need not bother. This drive also is a slim profile which should fit in basically any laptop that can take a 2.5" drive.
This is the drive I'm using for my installs now and what I'm recommending to all my friends and customers.

Wow my PC is awesome now
Nothing yet but I'll edit this if it breaks or something
I recently picked up an old PC with a 2.66 GHz Core Duo, 2 GB DDR2 RAM, Radeon HD 4650 and 500 GB HDD. It was so slow it was painful, thought I was going to have to replace the motherboard, cpu, and everything else. Instead I bit the bullet and installed 4 GB RAM and this SSD and the difference is unbelievable. I have another PC with a Core i3 and 4 GB RAM and this PC is just as fast if not faster than that one now. Can't believe the difference this makes. Silent too, of course, huge improvement over the roaring HDD I had in there. Can't say enough about SSD drives, if you don't have one yet, do it now!!!

Low price SSD for large space (250gb)
fx8350 and m5a99x r2 and windows 7 opens very fast. You won't
recognize your computer !
Works well and it didn't crash since i bought it
Sequential Write isnt as fast as i wish but You can barely go with it and play games, no worries with that !
I have it for months and i have no problem, got it on sale for 140 but you won't regret it. Works well, nice looking and fist perfect in my SSD slots on my CM 690 ii ;)

Shockingly fast SSD. Hopefully it carries the same reliability that Samsung drives are known for.
Incredibly fast read speed (500MB/s sequential; 320MB/s 4K-64 read). Fast write speed - faster than a Crucial M4 even!
TLC drives, by definition, can handle fewer writes to each flash memory cell (about 1000 writes per cell). However, that doesn't mean that the drive won't become obsolete before you wear out the NAND cells! Because of modern techniques ("wear leveling"), they can still last for years and years if you don't write many GB to the drive every day.
See Anandtech's writeup on TLC flash memory here:
According to Anand, you can write about 10GB to a 250GB 840 series every day and the NAND will last 23 years!
This is about my fifth SSD. I've had an OCZ Vertex 1, OCZ Agility 2, Intel X25-M (G2), Crucial M4 and now this SSD.
It's shockingly fast. Being the first consumer "TLC" SSD, I assumed there would be a performance tradeoff - TLC flash memory "triple layer cell" has 3 bits of data per flash cell compared to 2 bits for MLC and 1 bit of data for SLC. However, this drive actually boots and runs even faster than my Crucial M4, which was a high-end MLC just last year! My boot time has dropped in Windows 8 from ~15 seconds down to under 11!

Comment: The 840 exceeded all our expectations. It's faster, overall, than most of the previous generation MLC NAND based SSDs we have tested, which says a lot about Samsung's skill when it comes to designing a controller and firmware.
