This review is from: Samsung 840 Series Pro 512GB 2.5-inch SATA Solid State Drive (Personal Computers)
Fantastic SSD. Made all the better by the accompanying Samsung SSD Magician software, which allows configuration of SSD management and interface options such as caching (Samsung call it Rapid Mode) and over-provisioning. I bought the 512GB 840 Pro which came with migration software, this clones your existing hard drive to the SSD so that you can simply remove your old hard drive and install the SSD. Despite some character set issues leading to unintelligible messages while migrating, the whole process was done in around 1 hour 15 minutes (300GB to clone) and went flawlessly. I installed the new drive and the laptop booted first time, no issues.
The difference in boot times and general responsiveness would probably need to be measured in orders of magnitude, it really is that good compared to my old hard drive. While it's logical that any SSD with similar performance characteristics would provide similar increases in performance, the Samsung Magician software is really the icing on the cake in my view, it provides a great level of control over how the device is configured, as well as providing performance testing functionality, drive status etc.
The only drawback is the 840 Pro did not come with a SATA cable/interface to allow migration from my existing drive, so I had to purchase one separately. I bought this one "B006J2L0ZM which worked perfectly. In case that link goes missing in the future the item description is "Anker USB 3.0 to SATA 3ft Converter Adapter Cable for 2.5 inch/3.5 inch Hard Drive Disk HDD and SSD, Power Adapter included".
