From the Manufacturer
Enhanced Speed Technology
SanDisk nCache 2.0 technology uses a powerful two-tiered architecture to cache all writes, enabling burst speeds. With nCache 2.0 everything is written into the high speed buffer and consolidated before it’s written into the NAND flash memory array.
Endurance and Reliability Where it Counts
Double your drive reliability  - the more reliable your drive is, the less likely it is to crash. Proven shock and vibration resistance mean you won’t lose your data even if you drop your computer and, with dynamic and static wear levelling, the SanDisk Ultra II SSD is significantly more likely to last.
A More Efficient Drive
Cool, quiet and more efficient than a hard disk drive , your battery lasts longer on a single charge and your laptop has a longer life.
Always Know What’s Going On
With the SanDisk SSD Dashboard, you can see at a glance how full your drive is and how well it’s performing. Third party cloning software makes upgrading to SSD easier, too.

Eventually I bought this SandDisk Ultra II 960Gb SSD and a USB 3.0 external enclosure. Firstly the size of the SSD took me by surprise, it's only a small box and when you open it theirs simply the SSD, spacer and installation guide. I fitted the SSD into the external enclosure and cloned my Macbook's HDD to the SSD, this took around five hours so I left it overnight. In the morning before work I quickly swapped the drives (following an easy Macbook specific online guide) and booted up the Macbook.
The Macbook now boots to login screen in twelve seconds (it used to take just over one minute). Overall everything is faster and snappier, files copy instantly and Photoshop opens almost instantly. i would recommend this upgrade to anybody looking to massively improve their computer's performance.
Quick tip: If installing on a MacBook make sure you've set this as your boot drive in Settings, also enable TRIM.

In case anyone else has any trouble making the change, these are the issues I faced and how I overcame them: Firstly I bought an external hard drive enclosure with a USB3 connection. I popped the new SSD in the enclosure and plugged it in the laptop's USB. I was expecting to see it come up as a drive with a letter, but it didn't. I'm not sure if the next step was even necessary in the end, but I went into Disk Management (right-click Windows icon in bottom-left of screen and select Disk Management). Anyway, sure enough it showed up there and I manually assigned it a path and drive letter, but as I say, I'm not sure I need have bothered.
The next issue was finding software that would make the clone. First I tried EZ Gig IV which you're able to use free with a Sandisk product purchase, but it kept getting stuck at 86% due to some bad sectors error or something. Next Macrium Reflect which looked simple and was recommended by a lot of people, but seemed unable to deal with the issue of the SSD capacity being slightly smaller than the HDD despite the HDD not being full. Next up was EaseUS DiskCopy. I can't remember what the issue was with it, but I couldn't get it to work anyway. Finally I used Arconis True Image which is a paid for programme (maybe you can find a demo version or something, I'm not sure) and worked perfectly and only took 45 minutes to run.
After that I just swapped the drives, turned the laptop back on and held my breath expecting problems, but to my amazement it booted up in seconds and has been absolutely fine since. Best computer upgrade I've ever made!
I have been using this for the last 2 months and couldn't be happier. The system boots in 15 seconds.
Since a recent Yosemite update Apple has enabled TRIM support for third party drives again (use the command 'trimforce', for more see http://www.imore.com/os-x-10104-and-trim-support-should-you-turn-it). That also means FileVault can be enabled and won't deteriorate the speed and lifetime of the device. Without TRIM, FileVault would mess with wear-leveling of the SSD.
This is a 7mm thick drive. It comes with an extra piece of plastic to make it 9mm, however this plastic must be glued on. The Macbook originally came with a 9mm HDD, but given you have to screw the drive in all four sides into a caddy, there was no point adding this to it.
Note that this drive comes with a 3 year warranty, only the Extreme II and Extreme Pro come with 5 and 10 years, respectively.
