All components are designed and produced by Samsung.

TurboWrite for Faster Performance

Samsung TurboWrite technology uses an innovative write acceleration algorithm and a high-performance write buffer to dramatically boost the sequential write speeds for overall improved performance.

RAPID Mode for Efficient Data Caching

The 840 EVO includes Samsung Magician software with RAPID mode--an innovative DRAM caching enhancement which boosts PC performance by using idle DRAM as an ultra-fast buffer that improves system performance over time as the drive optimizes to your tasks.

Encryption Technology to Secure Your Data

The 840 EVO features Self-Encrypting Drive (SED) technology to encrypt your data and help keep your personal files secure. Because the technology is hardware-based, it eliminates performance degradation that can occur in software-based encryption.

Sleek, Sophisticated Design

At only 7 millimeters thick and weighing just 2 ounces, the 840 EVO Series SSD features a sleek, lightweight design. The stunning brushed aluminum design emphasizes luxury and refinement, but is durable enough to protect your data from loss due to shock, dust and corrosion.

All of the components of the 840 EVO are designed and manufactured by Samsung to ensure optimal quality, performance, and lifespan.

Included Software for Smooth Installation

This 840 EVO includes Samsung Data Migration software, which makes it simple to migrate your data, applications, and operating system from your hard disk drive to the SSD. In addition, Samsung Magician gives you all the tools to monitor, manage, and maintain your new SSD.

Easier-Than-Ever Upgrade Tools

Samsung's One-stop Installation Navigator provides a comprehensive guide for software installation, data migration, and hardware setup. The simple Samsung Data Migration software supports a powerful and unique "Custom Cloning" feature that simplifies the transition to your new SSD.

I had a very sluggish ASUS laptop that was about 2.5yrs old. It had a 2nd gen Intel Core 2 Duo processor. It took forever to boot up and website browsing was very slow. I mainly use my laptop for checking e-mail, web surfing and downloading photos from my digital camera. I'm not a power user so I just couldn't rationalize spending hundreds of dollars to replace it. Plus, I'm not a fan of Windows 8 which is installed on nearly all new laptops which dissuaded me from buying a new laptop (I have Windows 7 now).

Lately I've been hearing how replacing the old mechanical hard drive with an SSD would increase performance of any PC. I wasn't sure how much of an improvement it'd be since I wouldn't be updating the processor. After I put in the SSD it was a whole new world. The laptop booted up in seconds instead of minutes. Applications opened faster and everything was more responsive. Until now I never realized how much the mechanical hard drive bottlenecked the laptop's performance (as opposed to the processor). I don't think adding more RAM can increase performance this much.

I want to let you know that replacing the hard drive was super easy. I was overwhelmed at first because I couldn't find any easy installation instructions on the web. I was afraid that if I did it wrong I would lose all my data (especially my photos) or brick my laptop because I don't have the Windows Operating System installation CD (p.s. you don't need it). I thought I'd share my installation experience for people who are novices like me.

The steps below are for upgrading the hard drive on a regular PC laptop (i.e. I'm not sure if my instructions will work for a MacBook).

I have a late 2009 MacBook (the white polycarbonate one). It was performing unbearably slowly-- app switching and launching, booting, and even shutting down frequently took minutes. Scrolling in any app that accesses a lot of data (Evernote, even 1Password) was often very laggy. This was true even when I had large amounts of free/inactive memory. It was very frustrating, and I was almost ready to buy a new computer. However, I could see very high disk activity in the Activity Monitor during the slow periods and figured the bottleneck was probably my hard drive... so I went ahead and bought the Samsung 840 Evo and upgraded my RAM to 8 GB (Crucial 8 GB Kit (4 GB x 2) DDR3 1066 MT/s (PC3-8500) CL7 SODIMM 204-Pin for Mac (CT2C4G3S1067M )). Best computer decision of my life; the performance problems evaporated when I put in the Evo and the new RAM. Apps launch in seconds, no laggy scrolling, and I haven't hit the limit in terms of the numbers of things I can have open at once. Highly recommended.

P.S. Make sure you have an appropriate screwdriver (Wiha 96100 Phillips Screwdriver with Precision Handle, 00 x 40mm) and either a USB to SATA cable or a 2.5" hard drive enclosure. The screwdriver is needed to remove the bottom of the MacBook and to release the hard drive; the cable or enclosure is needed to connect the drive to your computer so you can clone your current drive before making the switch. Other screwdrivers might also work. Some articles I read suggested that a "T6" screwdriver was needed, but it wasn't for my MacBook model; can't speak about others.

If you need some more speed from your existing PC (especially laptops) this might be what you are looking for. Let's face it, most decent computers have enough RAM (4GB or more) and a fast enough CPU for "general purpose" use. But if you find your computer is still sluggish overall performance is probably held back by the hard drive. Traditional hard drives are mechanical and are limited by the time it takes for the platters to revolve and the mechanical components to position/seek before data can be read/written. An SSD is an "electronic" hard drive with no moving parts - which means significant speedups since there is no waiting on mechanical parts. In addition SSDs are more resistant to vibration/mechanical shock than hard drives.

Replacing the stock hard drive on a laptop (Win7, 64-bit) my Primary Disk interface score went from 5.8 to 7.6 (note the highest score is 7.9) and the laptop feels much snappier - boots in half the time too. I used the included Samsung Disk Migration software to perform the disk clone (using the SSD in an external USB SATA adapter). When it was finished I simply swapped the hard drive installed in the laptop with the SSD and Windows booted as usual. Note that you need to have a functional Windows installation for the Disk Migration tool to work - you install the tool under Windows like any other app (the tool is NOT a bootable CD with its own OS).

It's too early to determine reliability, which is the one concern I have with SSDs in general. SSDs use Flash memory and some SSDs use MultiLevelCell Flash (stores more than 1 bit per cell) - this allows pricing to be lower for a given capacity.
