Samsung SSD 850 EVO 2.5-Inch SATA III
Transform your PC with the Samsung 850 EVO 2.5-Inch SATA III SSD. Featuring Samsung V-NAND technology and Dynamic Thermal Guard protection, the 850 EVO ensures the integrity of your data even under heavy workloads. The 2.5-inch form factor is an ideal fit for most desktop PCs and laptops. With exceptional read/write speeds and TurboWrite technology, the 850 EVO can easily handle high-intensity tasks such as video editing, data analysis, and gaming.
What's in the Box:
- Samsung 850 EVO 2.5-Inch SATA III SSD, 4TB
V-NAND Technology Maximizes Endurance Under Intensive Workloads
The 850 EVO SSD features Samsung vertical NAND (V-NAND) technology that stacks cell layers on top of one another to increase density, performance, and efficiency while creating a smaller footprint. When compared with the conventional Planar NAND technology over a five-year period, V-NAND technology increases endurance, prolongs lifespan, and is more resistant to wear when under heavy client workloads.
Fast Read/Write Speeds with TurboWrite Technology and RAPID Mode
Using Samsung TurboWrite technology, the 850 EVO creates a high-performance write buffer area that accelerates performance whenever a write operation is underway. To boost performance for up to 2x faster* data processing speeds, you can activate RAPID Mode, a feature that reduces performance bottlenecks by utilizing unused PC memory as cache storage. These features make the 850 EVO ideal for demanding applications such as gaming, graphic and sound design, and data analysis.
Thermal Monitoring and Encryption for Data Security
The 850 EVO uses AES 256-bit hardware-based drive encryption** to ensure your data is kept secure from unwanted access. It also features Dynamic Thermal Guard, a technology that automatically throttles the drive's temperature when it approaches dangerous levels to reduce the risk of overheating.
The 850 EVO is also backed by a five-year warranty up to 300TBW (Terabytes Written)***.
Multiple Form Factors for Almost Any Need
The 850 EVO is available in multiple form factors to meet your specific needs. The 2.5-inch size is designed to fit most desktop PCs and laptops, while the SATA-based M.2 and mSATA are ideal for ultra-slim mobile computing.
* Compared to same drive w/out RAPID enable.
** AES 256-bit hardware-based encryption is compliant with advanced security management solutions, such as IEEE 1667 and TCG Opal.
*** 5 years or 300TBW, whichever comes first.

Don't buy an EVO. Look up benchmark reviews. Dollar to speed, I think the crucial drives are a better option, and their warranty isn't worthless.
The process of re-installing the OS X may not be straight forward for beginners, however there are plenty of youtube videos that are very helpful. Only thing I may have done differently is purchase the 500Gb version of this SSD instead. (However, if you are tight on cash, 250Gb should be more than enough for the average user).
I used the following video: https://www.youtube.com/watch?v=F82ThP-6jeA
Tip: Make sure to read the comments of this video if you encounter any problems during the process.
One thing to make sure you do before you start. Create a Windows Recovery Drive (on a USB stick) using the standard Windows "Create Recovery Drive" utility. In my case, a Windows 10 Creator Edition 64bit Recovery Drive. For whatever reason, after the cloning operation and replacing the HHD with the new SSD, my machine wouldn't boot from the SSD. Windows said there was a problem with the boot device. I inserted my Windows Recovery Drive (changed the BIOS to boot from the USB drive) and booted the Windows Recovery Drive. There is an option under advanced troubleshooting to repair the C: disk drive (our new SSD). After a couple of minutes, the repair function finished. Not sure what it repaired, but booting the SSD now worked perfectly and has been performing beautifully from then on. In my opinion about 10 times faster than the HHD.
For what it's worth, the SMART data of the SSD from my own personnal computers show over 40k hours, 5k power-ups, and over 45TB of combined read/write. One of them has been used and abused for half-a-decade, and all of them are still going strong at 100% health. They don't fail, they don't *require* firmware upgrade, they don't BSOD the system; they just works.
The warranty situation is a concern, though. This is the first and last of these SSD that I buy on Amazon, for that reason alone.
