Cons: Larger capacities command a big premium over HDDs.

Pros: Remarkably fast, cool, and quiet.
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.

Cons: None

Pros: 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.

Cons: Doesn't come with mounting hardware

Pros: Amazing cheap and fast SSDStarts up Windows in ~10 seconds
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.

Review Date: 07/04/13
Cons: Not as fast as the pro series

Pros: Fast (for the price), reasonably inexpensive, slim, good looking
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.

Cons: Nothing yet but I'll edit this if it breaks or something

Pros: Wow my PC is awesome now
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!!!

Cons: Sequential Write isnt as fast as i wish but You can barely go with it and play games, no worries with that !

Pros: 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 itQuiet
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 ;)

Cons: None

Pros: Very Fast SSD. Reasonably priced
With this drive i can boot 6-8 seconds, with windows 8. Awesome drive and the excellent software from Samsung is useable.

Bought this as a christmas gift for a friend's new build. It's got very fast boot times. It looks very nice as well.

Cons: 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:http://www.anandtech.com/show/6459/samsung-ssd-840-testing-the-endurance-of-tlc-nandAccording to Anand, you can write about 10GB to a 250GB 840 series every day and the NAND will last 23 years!

Pros: 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!
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!

Cons: write speed a bit slow

Pros: Speed, price, Samsung controller
This is my first SSD and I find this drive to be very fast. Even the advertised write speed is 250mb/s I find the drive to load windows and run programs very fast. Saving out large PSD files takes only a fraction of the time. Only time will tell if the new drive will be reliable.

Review Date: 12/30/12
Cons: No mount or cables included

Pros: Fast driveLooks nice (even if no one else will ever see it)
It is a fast drive, but it would have been nice to have a mount or at least a SATA cable with the drive. I'm a little concerned by reports of slowdowns, although I haven't experienced any problems myself. Slick design with brushed metal casing.

Review Date: 12/21/12
Cons: not much

Pros: Faster of the fast
I got this SSD as a boot drive for my gaming rig, and it boots FAST with Win8. Boots into win8 in less than 5 seconds is what I am getting everyday since the upgrade.This is a great deal, its not only cheap compared to the last years prices, but this is also one of the fastest SSD out there

Review Date: 12/16/12
Cons: -heard it only has 1000 write cycles vs 3000 or 5000. oh well.

Pros: -free because i got it as a gift-very fast compared to my old velociraptor
Id definitely get this drive. but if you are planning to do a lot of work, id suggest getting something else like the pro series

Review Date: 11/29/12
Cons: -TLC nand is not as good as async nand in budget SSDs and is not cheaper than async SSDs-no accessories but i had everything already

Pros: -looks great-is thin-very good upgrade from a hard drive
having a great time with this drive. Popped it into my laptop and makes thing boot a lot faster

Review Date: 11/27/12
Cons: Comes without anything. Need SATA cable to format it first, otherwise PC can not see it. And, it slow, way slow than declared.

Pros: Nice, slim, light and... Samsung quality (I expect!)
I will test it and probably return it.

Review Date: 11/12/12
Cons: TLC Write Speeds

Pros: Energy:Price ratio to comparable drives (M4, V+200, Agility 3/4, etc)Maintained high read speeds for TLC
Although these are poorly labelled (840 vs 840 Pro, TLC vs MLC flash), Anandtech had a write up about these drives specifically and ultimately I made the choice to grab one for a laptop because of the low energy:price ratio to comparable drives (Agility 3/4, M4, V+200, Hyper 3K, etc). LSI in the 840 120GB forum mentioned a review where write speeds had a significant decrease after relatively few after heavy load write testing. I haven't thoroughly tested it yet, but it's primarily for a linux/win dual boot with a shared virtual machine space for various testing/development. I'm restricted by my controller speed (SATA II), have yet to optimize my scheduler, and I've only been using the drive for a week, so I can't speak to write degradation.For now it'll be a 3/5 for Samsung's choice in marketing/labelling of the product and the lack of education they provide for consumers. I'm not so concerned about the ~3.5 year lifetime as a system would have to write ~10GB each and every day to reach this theoretical limit.
