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.

sleek, black very fast

Good Speed, Good value
The read/write speed for Samsung's 840 EVO Series is unbelievably good. The 120GB version is the perfect size to install the OS and still have plenty enough space left to store some of your favorite games/music/movies. Samsung also includes its Magician software and allows you to manage your SDD very efficiently.

Good value.
Probably not the fastest SSDs on the market, but worth the price
Bought this for my mid 2009 MacBook 13". Installed no problem and installed the newest OSX 10.9 Mavericks. The performance increase is amazing and is well worth the reduced HD size (160GB factory vs 120GB for this Samsung 840).

Anyone considering upgrading their MacBook to SSD should consider this drive.

Slimmer than some others
This was to put in an older laptop do decrease heat and noise while improving battery life. The heat/noise is gone. Battery life is marginally better. In terms of performance, I can't say much because the laptop doesn't use sata3. It's definitely faster than the 5200rpm drive that it's replacing though.

Experience: 1 Months

Samsung is a great manufacturer of the chips. Buy from the source
Good warranty
it's not the Pro
For a simple build this was great. Boots up Windows 7 in an instant. I know it is a bit slower than other SSD's i have, but for the mainly MS Office and web surfing computer i build for a friend's parents it was more than they expected. IT flies for those apps.

Experience: 10 Months
When it's functioning, works great, fast and reliable
After working fine for 5 months (light use), drive abruptly failed (Windows would not recognize drive and computer hung during startup, unplugging drive resolved issue. Data was unrecoverable).
Sent for warranty and was promptly replaced free of charge; replacement drive failed in same way 2 months later.
No complaints with the drive when it's working, or with Samsung's service (quick, professional, no issues).
Having 2 failures in 2 months is not confidence inspiring though.

Experience: 20 Days

May not be the quickest
A good inexpensive SSD that does what it's supposed to do. Good upgrade from HDD for a system drive.

Experience: 3 Weeks

Great Price
Great Speed
Only 120gb but that goes without saying.
This drive has been very good so far. It comes exactly as advertised. Anyone wanting a new ssd should give samsung a good look as they are well worth the price.

good looking
does not get hot
This ssd is a wonder. I've also tried the pro version (128gb) and the difference in speed is minimal, I guess the difference lies in the lifespan of the 2 drives. The magician software is very user friendly, and the firmware can be updated even if the os is on it. Overall this is the ssd to get.

Experience: 3 Days
Looks good !
Fast as hell !
None yet !
Bought 4 of 'em. Set up in RAID and they're simply awesome, would absolutely recommend to anyone with a low budget ! They're really fast and reliable.
