Experience a brand new, faster performance

Using the identical EVO technology as in the 840 EVO 2.5-inch SSD, 840 EVO mSATA has the same fast sequential and random read and write speed for every task. Samsung’s new 3-bit MLC NAND flash memory stores data more efficiently, increasing both speed and reliability. Whether it’s a heavy workload like video file editing or a simple task like a virus scan, 840 EVO mSATA runs every job smoothly and quickly. Multitasking is a simple job for this SSD, which can operate several tasks simultaneously. Also, with Samsung’s innovative TurboWrite technology, 840 EVO mSATA dramatically boosts the sequential write rate. The drive’s random read rate for light workloads (QD1) is 10,000 Input / Output Operations Per Second (IOPS), the best in the industry. To improve system-level performance, turn on the RAPID mode on Samsung Magician software to use the PC’s free DRAM as a cache. Working more efficiently with the high-performing Samsung SSD 840 EVO mSATA will change your everyday computer usage. Now, your computer will wait for you—not the other way around.

Unmatched reliability for consistently high performance

Toughen up your PC with 840 EVO mSATA. Shocks, vibrations, high temperatures—bring it on! With its robust strength, 840 EVO mSATA boasts an incredibly long life expectancy and a very low failure rate thanks to Samsung's unique technologies, such as TurboWrite. What’s more, Samsung offers a 3-year warranty to back it up. The reliability of 840 EVO mSATA does not apply only to its physique. you can track your SSD’s health status through Samsung Magician software, management utility designed to work with all Samsung SSD products. Samsung Self-Monitoring Analysis & Reporting Technology (SMART) enables Samsung Magician to warn you of any unforeseen errors before they occur, and you’ll be prepared. In addition, Samsung’s Dynamic Thermal Guard Algorithm in 840 EVO mSATA’s firmware monitors the temperature of the SSD, preventing it from overheating. When the SSD is exposed to hot weather or extreme temperatures, the algorithm controls the SSD’s power supply to keep it cool. Plus, with 840 EVO mSATA, your laptop PC becomes lighter and more energy-efficient, which means you can carry it with you more.

Protect your data with a secure encryption engine

When you take your laptop on the road, you expose your personal information to new vulnerabilities. But don’t worry, 840 EVO mSATA’s Self-Encrypting Drive (SED) security technology will help keep your data safe at all times. The drive includes an AES 256-bit hardware-based encryption engine to ensure that your personal files remain secure, even if you lose your laptop. Being hardware-based, the encryption engine secures your data without the performance degradation that you may experience with a software-based encryption. Also, 840 EVO mSATA is compliant with advanced security management solutions (TCG Opal and IEEE 1667).

Stay connected longer with extended battery life

When you're on the move with your PC, the last thing you want to have happen is to run out of power. With Samsung 840 EVO mSATA installed, you can stay connected longer and power up faster thanks to Device Sleep (DEVSLP). Your PC no longer needs to go into standby mode to conserve battery life, nor do you have to wait for it to power back on. Take full advantage of your AOAC (always on always connected) professional life, while enjoying a longer battery life.

Keep your PC performance safe from heat

When you’re immersed in your work, you might not notice that your PC is burning hot and struggling to keep up. With 840 EVO mSATA, your PC stays cool, even when you sometimes overwork it. 840 EVO mSATA includes Dynamic Thermal Guard protection, which monitors and maintains optimal operating temperatures for the drive. The throttling feature can drop the SSD’s temperature when necessary to protect your data and ensure the responsiveness you expect.
