I bought this for my Dell XPS 15.6" L502x.
Installation was a breeze (simple as installing a 2.5" Sata HDD). My Dell XPS L502x has 2 x sata 3 ports for maximum compatibility with this product.
Literally plug and play, no configuration required. I had to install windows on it (I dual booted ubuntu and windows, both off this drive. I partitioned the SSD into 4 drives).
Windows boot times are SERIOUSLY quick. It doesn't even finish the Windows animation boot screen!!. After the initial hardware post, boot time into windows is less then 10 seconds (includes the initialization of anti-virus and start-up apps), its literally Boom, Boom, BOOM! and you have a ready to use windows system. Ubuntu boot times are even quicker!!.
Seriously Quick Drive, Firefox and Chrome open with a second, web browsing is so much faster (faster access times to cache), and overall performance of the laptop has increased MASSIVELY. (Battery life has increased very slightly as well!)
I will almost certainly be buying another one of these for my PC in the future (or perhaps 2 and run them in Raid 0!!).
Excellent service & delivery from Amazon (as always!)
