Add Storage to Ultra-Thin Laptop or Desktop PC

Offering 250 GB of storage in an ultra-thin form factor, the Samsung 840 EVO mSATA SSD is an ideal performance upgrade for the latest compact laptop and desktop PC designs. Despite its small size, the drive gives you plenty of room for all your apps and media, and it also delivers faster bootup and application launching.

TurboWrite for Significantly Faster Performance

The Samsung 840 EVO mSATA provides exceptional write speeds up to 520 MB/s thanks to an ultra-fast cache called TurboWrite. This allows your PC to handle bigger workloads so you can get work done faster.

RAPID Mode Improves Drive Performance in Real Time

RAPID (Real-time Accelerated Processing of I/O Data) Mode enhances disk performance by utilizing free DRAM memory as a cache. With RAPID Mode enabled, the 840 EVO mSATA analyzes your application and data usage and adapts -- optimizing performance and eliminating bottlenecks.

Tackle Everyday PC Tasks Without the Wait

With a faster controller and improved firmware, the 840 EVO mSATA is incredibly fast at executing common tasks. Higher random read performance translates to faster startup, shutdown, application execution, web browsing, and more.

Low Power Consumption, Longer Battery Life

The next generation of NAND combines with advances in the MEX controller to make the 840 EVO mSATA a remarkably efficient SSD. Device sleep mode ensures that when your ultra-thin laptop is idle, it consumes very little power. The drive also generates less heat than traditional SSDs and helps your battery last up to 45 minutes longer than using traditional hard drives.

256-Bit Encryption Protects Your Data

The 840 EVO mSATA features self-encrypting drive technology to safeguard your data. AES 256-bit hardware-based encryption keeps files secure without sacrificing performance. To ensure that you get the most of these features, the included Samsung Magician software guides you through the setup and maintenance of your drive.

Data Migration Software for Easy Upgrade

Samsung's Data Migration software makes it easy to upgrade your system to the speed, security, and performance of the 840 EVO mSATA SSD. A custom cloning option lets you exclude large media files from the cloning process and move them to another storage device to avoid a separate backup process.

Note that mSATA-to-SATA and SATA-to-USB connectors are sold separately.

Durable, Genuine Samsung Components

Samsung's rugged 840 EVO mSATA SSD is shockproof and vibration proof and is made from 100-percent Samsung memory components. Dynamic Thermal Guard protection ensures optimal operating temperature.

    5.0 out of 5 stars BEST UPGRADE EVER!
    Reviewed in the United States on June 29, 2014
    Verified Purchase
    I used the 840evo as a boot drive for my Lenovo T520 and it works great. I had reservations about using this mSATA drive over a SSD since my mSATA slot only support up to SATA 2 speeds. However, the upgrade is well worth it. Booting speed is now about 15-20 seconds. Internet speed feels much faster due to the browser being able to open up instantly. I have done a 4gb to 16gb ram upgrade about a year ago, but I must say this is definitely the best upgrade you can do to your system.

    One reminder: This may be obvious to some advanced users, but make sure to use the Magician software by downloading from their official site. Use the magician software to 1. optimize the drive and 2. enable RAPIDmode. The difference is significant. My speed tests done by magician gives me the following numbers:

    BEFORE optimization+RAPIDmode
    seq read: 284mb/s seq write: 266 mb/s
    read IOPS: 52435 write IOPS: 50163

    AFTER
    seq read: 353mb/s seq write: 559 mb/s
    read IOPS: 65021 write IOPS: 62962

    One little con: the product came with no detailed instructions on how to use the data migration (which I didn't need anyways) nor the magician software. For beginners like myself, it would have helped if Samsung told us the basics on the two software (where to get them, what they do, etc.). I almost missed out on a few significant ways to boost my speed (not to mention the magician takes care of firmware upgrades as well).

    Overall, solid drive!

    5.0 out of 5 stars Physical installation in laptop was easy (verify that your laptop has an mSata slot)

    installed in Dell Insperion R17 I7 5720 as the Win 7 operating system drive so I could have ssd performance and still install a 1tb hdd for storage. Physical installation in laptop was easy (verify that your laptop has an mSata slot), however, not all laptop bios's (Dell included) allow setting an mSata drive as a boot drive so you may have to Google instructions and use a free program called EasyBCD to change your boot settings. Works great, very fast (Windows Experience Index 7.8). You can download free Samsung Data Migration software which makes cloning your existing operating system drive easy. Free Samsung Magician software automatically optimizes your system for increased ssd performance. Highly recommended for an incredible performance boost.
    Drive doesn't come with mounting screws so you may need to liberate one from your laptops hard disk caddy.

    5.0 out of 5 stars Not much to say. It's that good.
    Reviewed in the United States on January 2, 2015

    I installed this in my new MSI GE70 2PE laptop, and it made a good machine even better. The MSI comes with an excellent 7200 RPM HDD, but even with fast boot enabled it took time for the system to load its startup apps, which I worsened by adding my own programs.

    I managed to get the laptop to boot from the mSATA by removing the HDD and using the restore DVDs to reinstall Windows 8.1 to the SSD, then returned the HDD to the laptop after the restore was completed. I used partition software to turn the HDD into a drive for storing less critical programs and data. Even with fast boot disabled in Windows, it takes less than 5 seconds to get to the logon screen; the rest of the startup drivers and apps takes less than 30 seconds after that.

    Some reviewers complained about the lack of a screw. I find that hardly a reason to take one star out of an otherwise excellent and basically flawless product. Although in my case, MSI was smart enough to have the needed screws already inside the laptop even if the two mSATA slots were empty!

    I have never tried Samsung SSDs for my desktop, but I'll sure will consider them for the next PC I build.

    All aspects of the upgrade from the online purchase from Amazon to the delivery on time. The installation went off with very little difficulty. The clone software from Samsung did not transfer all of the partitions from the original disk so I had to start it from scratch on a new install. Not a real major issue. The SSD made the boot up and the response time from key stroke to next function go as fast as a blink of an eye. Impressive. Very pleased with this addition. The Samsung Magician software made it easy to maximize the SSD performance. Great Job.
