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 innovativeTurboWrite 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

Protect your PC strongly

Protect your PC strongly

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).

Turbo write

Always be in high acceleration

If you are a speed demon, you will certainly enjoy the new level of excitement 840 EVO mSATA offers you. Thanks to Samsung’s TurboWrite technology, 840 EVO mSATA can deliver much faster sequential write speeds compared to the previous 840 model, tripling the speed from 130 to 410MB/s in 120GB drives, and doubling it from 250 to 520MB/s in 250GB drives. Utilizing an innovative write acceleration algorithm and high performance write buffer, you can expect accelerated speeds and higher satisfaction from your PC.

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.

Rapid mode

speed up

Enjoy rapid performance by switching to a higher gear

Like changing gears in a car, with Magician software you have the option of RAPID mode, enhancing performance by processing data on a system level through the use of free PC memory (DRAM) as a cache. Depending on your PC memory, you can expect higher performance and more efficient command processing, which improves with repeated tasking. Boost into a higher gear to vastly improve QD1 random write performance to almost the same level as QD32.

Dynamic Thermal Guard protection

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.

A Variety of Capacities

No need to limit capacity

There’s no need to be concerned with sacrificing capacity for a conveniently thin form factor. Though small in size, the 840 EVO mSATA is big on capacity. Boasting the same capacity options as the larger 2.5-inch 840 EVO but much thinner (2.75 mm / 0.11 in.) and lighter (8.5 g / 0.3 oz.), it's the smart choice for your ultra-thin laptop PC. With a wide range of capacities, from a basic 120 GB to the spacious 1 TB – the only true 1 TB capacity SSD around, 840 EVO mSATA helps you find the perfect SSD for your laptop PC upgrade. If you were previously reluctant to upgrade to an SSD because the capacities were lacking, now is the time to reconsider your SSD options. With ample sizes up to 1 TB, 840 EVO mSATA satisfies your extensive storage needs. Plus, 840 EVO mSATA gives you a real 1 TB drive running inside your computer rather than the 960 GB SSDs previously labeled as “1 TB drives.” Choose the right-sized SSD for your laptop PC, all with the superb quality that a Samsung-made SSD can offer.
