From the Manufacturer

Improve the performance and extend the life of your computer or gaming console.
Fast Performance for Gaming, Multimedia, and More

Upgrade your computer or gaming console and enjoy fast, reliable performance with the SanDisk Extreme II Solid State Drive. This SSD features a storage capacity of 120 GB (1) and delivers sequential read speeds of up to 550 megabytes per second (MB/s) and sequential write speeds of up to 340 MB/s (2). This allows you to multitask, run graphics-intensive applications, and transfer large files with ease, as well boot up and shut down your machine without having to wait. SanDisk's tiered caching across storage layers optimizes the write speed and disk endurance and ensures your data is stored in the safest place.

Designed to Keep Your Data Safe

Housed in a durable aluminum case, the SanDisk Extreme II has been engineered to resist shocks and vibrations, preserve the integrity of your data, and prevent data loss. Dynamic and static wear leveling help extend the life of the drive, while over-provisioning and over-clocking ensure consistent performance even under the heaviest workloads. Other features include bad block management, which prevents uncorrectable memory errors, and thermal throttling, which protects critical drive components against extreme temperatures.

Quiet, Stable Operation and Low Power Consumption

Unlike traditional hard disk drives, solid disk drives contain no moving parts, making them cooler and quieter and less likely to break. SSDs are also more energy-efficient than standard HDDs for longer laptop battery life. According to a SanDisk research paper, an SSD can extend the life of a laptop by up to 33 percent (3).

SanDisk SSDs are engineered to deliver sustained high performance over time.
Sustained High Performance for Gamers and Professionals

Rather than focusing on peak speeds, which may be achieved only for a few seconds at a time, SanDisk maximizes real operating speeds and performance consistency over a long period of time. Thanks to a Mean Time Between Failures (MTBF) of 2 million hours (5), the SanDisk Extreme II can deliver years of fast, reliable performance.

Tiered caching across storage layers increases write speed and disk endurance.
Faster Write Speeds and Safer Data with nCache

To optimize the user experience, the SanDisk Extreme II contains nCache technology, a large, non-volatile write cache that consolidates small writes to boost random write performance and the long-term data endurance of the drive. This proprietary technology from SanDisk is designed to mediate how modern-day operating systems and flash memory interoperate. The result is faster response times and better multitasking without stuttering.

An ideal upgrade for a laptop or desktop computer or a gaming console.
Reliable Performance with an Extended MTBF

Like other SanDisk solid state drives, the SanDisk Extreme II offers a Mean Time Between Failures (MTBF) of 2 million hours based on a parts stress analysis. MTBF is the predicted amount of time the drive will operate without failure and is a measure of reliability. Consequently, you can get more out of your computer or gaming system with less downtime.

This SSD monitors and provides updates on its health status.
Monitor the Health of Your SSD in Real Time

Thanks to S. M.A. R.T. (Self-Monitoring, Analysis, and Reporting Technology) capabilities, this solid state drive can detect and report on various indicators of reliability and alert you of an impending drive failure while there is still time to take action.

SSDs deliver cool, quiet operation and consume less power than typical HDDs.
The Advantage of SSDs

Why replace your computer's hard disk drive with a solid state drive? SSDs offer a number of advantages over traditional hard drives. Because they contain no moving parts, SanDisk SSDs are less likely to break and they deliver cooler and quieter operation and consume less power than standard 7,200 RPM hard drives (4). In addition, SanDisk SSDs are cased in aluminum and are rigorously tested to withstand shocks and vibrations. This, along with fast read and write speeds for games and more, makes an SSD a compelling option, and it's easy to remove an HDD and install an SSD without losing any data.

(2) Up to stated speeds; performance may vary depending upon drive capacity, host device, OS and application. 1 megabyte (MB) = 1 million bytes. (3) SanDisk SSD Deployment Whitepaper, 2013.

I have used many SSD's over the years and I can easily say I am the most pleased with this one. It is fast, lightweight and extremely reliable. In order to fully utilize the benefits of this SSD in either Windows or Linux, I would recommend the following:


- TRIM is enabled by default, so you don't have to turn it on.
- Disable System Restore. This wastes writes on the device and shortens its lifespan.
- Disable your pagefile. When using an SSD this quick it is not needed and it also wastes writes. Just make sure you have at least 4GB of RAM in your system if you do this.
- Turn off timestamps on NTFS. This is unnecessary and can reduce the life of your SSD.


- Turn on TRIM. You can do this by adding discards to your /etc/fstab. You may also want to add noatime as well.
- Add a persistent RAM Disk assuming you have adequate amounts of RAM.
- Use a low latency I/O scheduler (e.g. deadline).

With these options enabled, you will get the most out of your SSD and wonder why you waited so long to get rid of you old spinning hard drive.

Note: If you want to make an exact copy of your existing hard drive to your new SSD:

- Grab and external USB drive carrier that will accept your old hard drive.
- Download a Gparted Live boot disk.
- Take your old hard drive and place it into the external USB drive carrier.
- Install your new SanDisk SSD.
- Boot your system into the Gparted Live Boot Disk.
- Run Gparted and note the drive ID for both your new drive and old.
- Open a terminal and run: dd if=/dev/sdX of=/dev/sdZ (where sdX is your OLD drive and sdZ is your new hard drive. The actual ID's will most likely be /dev/sda and /dev/sdb).

I edit HD video, Terabytes of it. Upwards of 1000 clips per project. I've been relying on a great but slower raid box which i have some green drives in. It's reliable as heck, but i've been desiring a smaller, faster drive, which i could keep my current projects on as a scratch,

Importance for editing video
-Editing is tons of IOPS/read/write operations. Comparing my old drive vs this one you can instantly see the differences: When opening the project with 1000 files, how fast does it open? in adobe premiere it shows you the countdown of all the files it's re-connecting to when you open. Old drive: over a minute. Sandisk: a few seconds.
-Playback and clicking between different points in time. Old drive: some lag, some hiccups. New drive: instantaneous, almost all the time.

Other SSDs?
-I was dead set on the 960gb M500 for awhile, it's a great bang for the buck, but my friend turned me on to the deal this one had for $369, and noted in reviews, the M500 was a chunk slower in certain operations than this sandisk.
-The samsung evo pro is probably the equal competitor, similar performance, similar price, but this drive on sale edged it out for me.

What's to like
-Got it for under 78 cents per gb. not as great as the 50 cent per gigabyte deals, but this is much better than average SSD
-Capacity is good if you're editing compressed footage, can fit a feature film plus a lot more from C100 24mbit files. If you're editing RAW files, probably should RAID multiple of these
-High IOPS. This is just as important as read/write, espectially for video editing, which is tons of referencing.

I recently got a brand new laptop (Lenovo ThinkPad T431s) that comes with a Toshiba 7200rpm HDD so I decided to get an SSD to speed things up because I got tired of waiting for applications to load. So I decided to go with a SanDisk Extreme II 240 GB and man, SSD's will make any computer feel like it's from the future. The ThinkPad T431s is already fast because it comes with 4GB of ram and a core i5-3337U but swapping the HDD with an SSD made it 100x faster. I feel like HDDs really hold back a computer's performance. The SanDisk Extreme II 240GB literally blew me away by the performance that it has. My Windows 7 disk experience score went from 5.4 to 7.9 which is the highest it can go on Windows 7.

I do a lot of backups and transfer large files with my laptop and it used to take forever when I had my HDD but now everything is blazing fast. I know that this product literally came onto the market just a few days ago but it seems it's receiving very good reviews and so far I'm very impressed! When I was on the HDD, I would get around ~5hrs of battery life but now I'm getting around 6-7hrs. I travel a lot so battery life is very important to me and being able to have an extra 1-2hrs is awesome. This SSD is quite an improvement from my Toshiba HDD that I had before in my laptop but I'm really impressed by how lightweight this new drive is and how fast it.

It also generates almost no heat and is obviously silent to the ear. I couldn't stand the weird noises that my Toshiba HDD would make during the night. The access and read speed are as advertised and I did a benchmark with CrystialDiskMark, the results are below. I use my laptop for video editing/web development so I use programs like Adobe After Effects, Dreamweaver and Photoshop quite a lot.
