I can only echo the other reviews here in saying that adding this SSD to my desktop PC has provided the best performance boost I've seen in all my years of PC 'fiddling'. My PC now boots in less than half the time and applications spring to life instantly. I highly recommend reading Khushiman's review of 13th December for some excellent advice on using an SSD (no point in me repeating it). I too have a separate mechanical hard drive for all my applications & data and use my SSD purely for the operating system. Samsung's 'SSD magician' software tool does a good job in helping you configure Windows for SSD use but I also suggest searching for and reading the 'SSD optimisation' guides available on the internet for some additional tips and tweaks to get the best out of the SSD. An excellent buy.

Unlike other people I decided to do a clean install of Windows7 on this and after setting things away I popped out to the kitchen to make a cup of tea... when I came back the first stage of the installation was done and the pc was about to reboot. Incredible.
At the moment I'm only using it for my OS with all of my data being stored on 2 x 500 Gig disks... but I'm mightily impressed with the speed of the disk and will certainly be looking to move over to SSDs when the price drops a bit more into my price range.
For me the main attraction of the Samsung SSD is the fact that everything is made in house so there are less likely to be any compatibility issues...
Don't forget if, like me, you are putting this in a tower system you will need to take into accounting the smaller profile of the 2.5" SSD if you are putting it into a 3.5" HD bay or a 5" DVD bay.
I found both of these usefull:

Akasa 2.5/3.5 inch to 5.25 inch Mounting Adapter

Icy Dock MB990SP-B Dual 2.5 inch to 3.5 inch SATA and IDE SSD/HDD Bracket

Ive not done speed tests, but so far it's been very nice.

It's small and lightweight but the metal case feels like cheap tin that would break really easily, although I'm not sure if that's the case.
I guess it doesn't matter much since it's for use internally.

Vine Customer Review of Free Product ( What's this? )
Had a 4 year old Sony Vaio AR51 laptop that sometimes felt lethargic in use. Already upgraded the memory to the max supported a while back, and it certainly improved things, but moving to this SDD totally transformed it, bootup time is literally cut in half, and applications now open up really quickly (often you never actually see the splash screen). I took the clean install route for Windows 7, as the laptop had fulled up with some stuff I didn't want anymore, but you could equally use the included Data Migration tool to move your current Windows installation to this new SSD, I ran it up and it seems simple enough to use, and nice that Samsung included it, as it's a fine alternative to having to pay for Norton Ghost or Acronis TrueImage and it's nice that Samsung included it.

The drive package itself is basic, just the drive, no 3.5 adapter plate, no screws, but then the price reflects this, so I have no problems with this, and the packaging is minimal but adequate.

Performance wise, the read speeds and seek times are unsurprisingly very fast (as are all SSD drives) the real difference between SSD drives is all down to the write speed performance, and this one seems pretty good, from CrystalMark I got the following results (an older system, newer systems may benchmark better still):

Sequential Read 470 MB/Sec
Sequential Write 247 MB/Sec

All in all, a great buy. The Data Migration software is something many other drives omit to include.

SSD's continue their march towards higher capacities at lower price points and so have started to move from an enthusiast option to more of an everyday option.

The Samsung 840, although not as fast as their Pro version is one of the best drives out there available to the consumer. It replaces the equally fantastic 830 but now ships in two flavours; standard and pro. The main difference being that the pro offers faster write speeds than the non-pro version and it has tweaked many things under the hood compared to the older 830 models, including a new controller and better wear levelling that should make the drive last longer and stay at top performance.

The drive itself is in a nice matt black with orange fonts and is 7mm thick which makes it suitable the newer laptops that require thinner drives.

I use an ssd for my main os and apps and a mechanical drive for storage of music/docs etc .

Samsung's software suite handles drive cloning; drive wiping; firmware updates the lot. And is very user friendly and easy to use. It even includes benchmarking tools and will optimise your system for ssd use if you didn't previously have one. I.e. turn of defrag etc. Though just re-running the windows experience index will take care of that too. I used the built in clone feature to clone my system from my crucial M4 to the 840 pro and then to this drive. My system is running spot on. For those that don't want to use Samsung's software I highly recommend the free programme 'Macrium Reflect' for cloning.

I have deliberately omitted bench mark results as in reality they can vary between systems (not to mention benchmark software used) and I don't much care of benching, unless you want bragging rights....
