Did you purchase a Sandisk Ultra II? If so, How do you like it and any problems so far?
I just purchased the Ultra II 240g model which uses the same memory and marvel controller. the larger models use a different marvel controller.
I imagine my drive would be very similar to yours and I am very impressed with boot time and performance. I am very happy with this and am using it as my boot\OS drive with Win 7 pro x64.
The one thing that bothers me are the buyer reviews with this Sandisk line.
a lot of the reviews go something like this --"Was amazing until it died"
Reviews of suddenly died after 2 weeks, Suddenly died after 7 months.
I hate having this stuck it the back of my head.
The only advice i can give is keep frequent backups, as you should anyway.
I use Acronis 2014(which I used to clone my platter without any issues. Booted right up). Macrium Reflect should be just as useful. Minitool partion wizard is also a great free boot utility to resize, ect partition. It has more features than Acronis Disk Director and is free which is a plus
