First of all, the Samsung 840 uses triple-level cell (TLC) memory vs. the multi-level cell (MLC) memory used for almost all other SSDs. So what is the difference between TLC and MLC? With TLC memory, 3 bits of information (8 possible values) are stored per cell instead of the 2 bits (4 possible values) in MLC memory. This might sound better but it also means that the cells are used more and there is less voltage fault tolerance. In the most simple terms, you can think of cells being "filled" or "emptied" by applying voltage. When 3 bits (8 possible values) of information are stored per cell, the SSD may have to apply voltage to the entire cell multiple times even though just one bit of information is encoded (depending on the bit being changed). The multiple voltage applications to each cell also slows down the write speeds and causes more wear in general.

Performance-wise, the Samsung 840 is actually worse than the previous generation Samsung 830. On the Passmark benchmarks, it is slightly lower than the OCZ Agility 4 which uses asynchronous MLC NAND flash.

Right now, the top three SSDs (best selling and best reviews) on Amazon are the OCZ Vertex 4, Samsung 830, and the Crucial M4. However, all three of these SSDs are cheaper and they perform better than the Samsung 840. Eventually, the TLC NAND should mean that the Samsung 840 will sell for less because less NAND is used. However, it is not worth it right now. To be safe, I would say that you should wait until the drive is at least 10-20% cheaper than the three drives above due to the uncertainty of how it will perform in the long run.

One puzzling thing is that I couldn't find any mean time before failure (MTBF) estimates for the 840, while the MTBF for the 20nm MLC based 840 Pro is 1.

First off, forget Norton Ghost. Even though the Samsung SSD Magician software provides a link to Symantec for a 30 day trial version of Norton Ghost, the trial version won't clone your old HD to the new HD. Save yourself some frustration and download time by going to the Samsung Support website and downloading the Samsung Data Migration tool. Once I downloaded and installed this excellent software tool, the cloning went quickly (2-3 hrs.) and easily. I was upgrading from a 128GB Kingston SSD with about 110GB of data on it, so your mileage my vary on the cloning times. The Samsung SSD Magician software is also powerful and easy to use. I was able to optimize my Windows settings and the SSD settings in no time to get optimal performance from the SSD. The Over Provisioning, while a little scary, went well and took up about 10% of the overall HD space, but if this extends the life and reliability of the drive it will be worth it. Overall I'm glad I bought this SSD, however I wouldn't recommend it to a non-techie friend or relative. The sparse (virtually nonexistent) documentation made the cloning process more frustrating than it had to be and I consider myself an advanced user. Minus one star for the poor documentation.

The drive improves the computer's performance noticeably. I agree with other reviewers that the documentation is lacking, which costs it a star in the rating. However, the Samsung Data Migration program worked flawlessly. Don't bother using the Data Migration and Magician programs on the disk -- they are out-of-date. Although the programs will ask you if you want to update them after you install them, just get the latest versions from Samsung's site before you start.

My 2010 Dell XPS 8100 desktop did not come with a Windows 7 disk. I had hoped to use Windows Image Backup from an system image I had created a couple of years ago and stored on a second HD, to have a cleaner installation with the SSD. I had created a Windows 7 Repair Disk at that time for the purpose of restoration in case of a problem like HD crash. However, this method fails with an error "No disk that can be used for recovering the system disk can be found" . From what I can determine, Windows will not restore to a partition smaller than the one the image was made from. And my old HD was much larger than the SSD. There may be a work-around for this, but maybe it is not worth the bother as everything worked fine after the migration.

UPDATE: Since I usually wipe my computer clean and start over with a new factory image every few years, and I had not done so with my 4+ year old computer, I decided to do the factory restore on the old HD, and then cloned it to the SSD. Also, after your SSD is cloned from your HD, you cannot create a new Windows Image Backup file from the SSD. You get an error of "Not enough disk space . . " even thought he target drive is plenty big enough. I had to make the Windows Image backup file from the old HD.

Samsung is known for good hardware. I can't comment on this hardware, because I don't have it installed yet. But, the setup and install process is terrible. First, the product was supposed to include SATA data and power cables. The power cable was missing from the package. I intend to use the SSD drive as a replacement for my existing Win8 boot drive. So, the OS needs to be cloned to the SSD. The clone software that was supposed to be provided, was not present on the CD. You have to register the product and download the software. The user manual consists of a few pictures. The SSD Magician; software won't install on a Win 8 system. The cloning software (once downloaded and installed - which took four tries) fails with a numeric error message (Samsung says it works for Win 8.) There doesn't appear to be any way to contact Samsung technical support other than email and they haven't responded to my question about the missing cable. The help document tells you to call a 8xx number which is closed on weekends. I did find another clone software (Drive Clone 9) which seems to be working - but that is another $30 cost. This is not an install for the faint hearted - especially if you want to use the drive as your boot drive - which almost everyone will want to do. If you have the install media, and want to start from scratch, that might work better.

Follow-up Note: I was able to get the drive installed and working. The Samsung Drive Clone software does not work - it consistently fails when trying to clone my C: drive. I purchased a copy of DriveClone 9 from FarStone, and that works perfectly. It took about four hours to clone the drive, but it was done perfectly with no errors. A free 14-day trial of the software is available so you can try it to make sure it works.
