Samsung 840 Pro 512GB review
Is there anything Samsung isn't good at?
Fastest 512GB drive we have tested ; Good 4K random read figure
Newer drives beat it on price
This is a very fine drive: not only is it one of the quickest around, it comes with the peace of mind that you're buying from a big outfit that is very unlikely to disappear. If you do have a problem, the odds of being able to cash in your warranty are...

Samsung 840 Pro 256GB review
Well over £200 for a 256GB SSD? Aren't SSD prices supposed to be going down, not up?
Good performance ; TLC flash memory ; New controller and firmware
Slight drop off in performance over time

Samsung 840 Pro 512 GB review
Samsung backs this MLC-based drive with a 5-year warranty, although platform support is resolutely limited to Windows. It's possible to adjust over-provisioning using the SSD Magician for Windows software, as well as run rudimentary benchmark tests.
There's little doubt that when working correctly the Samsung 840 Pro is one of the top consumer solid-state drives available today. Pricing is very competitive and the essential small-file IOPS performance is on the money too.

Samsung 840 Pro 256GB review
Samsung's model 840 Pro is the fastest 240GB SSD we've tested.
The Samsung 840 Pro is currently the fastest consumer SSD on the market. You'll pay a little more for it, but you always pay more for the best.

Samsung SSD 840 Pro (256GB) - Here Comes Big Daddy
The Samsung SSD 840 Pro arrives in our labs with big expectations. Widely acclaimed, we find out if it how it fares against some of the best SSDs we have tested.
Blistering performance on AS SSD, CrystalDiskMark and Iometer; Intuitive and useful Samsung Magician control panel; Completely in-house developed (memory, controller and firmware)
Inconsistent performance; No accessories such as installation bracket; Commands considerable premium over other high-end SSDs

Samsung 840 Pro SSD: More Speed, Less Power, And Toggle-Mode 2.0
Samsung is taking the wraps off its new flagship 840 Pro SSD. It's promising better performance, lower power consumption, a five-year warranty, ...
Our 512 GB sample includes eight ICs marked K9PHGY8U7A-CCK0. According to Samsung's decoder ring, the P indicates an MLC octal die configuration, while HG tells us that each package is 512 Gb (64 GB). So, we have eight 64 Gb die per package, yielding...

Samsung SSD 840 Pro solid state drive
This drive is one of the best upgrades available for laptops and desktops that need a speed boost
Fast reading and writing speeds ; Very light ; Can be found at a good price ; 5-year warranty
Power consumption reduction not significant against other recent SSDs we've seen
Samsung's SSD 840 Pro is one of the best options on the market if you're looking for a solid state drive with excellent writing, as well as reading performance. It's also one of the lightest units we've seen.

Samsung 840 Pro 512GB
This new drive is actually the professional version of the 840 series, so in a way it's a double upgrade since the 830 series didn't have a Pro version. The new drive differentiates itself from the rest of its SSD siblings by using Samsung's...
