Add this caddy to your notebook to give you another hard drive. Simply remove your CD/DVD-ROM drive and put the Caddy (with the added hard drive) in it's place... This is a good working adapter and is Guaranteed. This is not original product, but it has 100% original/genuine quality.
Great for backups or if you just need more space! Another thing you could use is to have a complete image of your main hdd (which has operating system), you always have a peace of mind knowing that you have a complete good working HDD backed up, whenever the main drive is infected with virus or spyware, you could take the back up and swap with main drive, do a complete image of it, then swap again, no need to re-install the OS and all applications. NOTE always keep the original image, only use it to image the main drive (do NOT use it as main drive).
1. Fast & Reliable connection, just as the primary HDD
2. Fully integrated into laptop, no cables/PSU/software driver needed
3. Dual boot, Support installation of 2nd operating system on the 2nd HDD and boot selection.
