Buy a 1TB PNY SSD and get a 500GB backup drive free right now at Amazon

Amazon is offering a great deal on storage right now: When you buy a 1TB PNY CS900 internal SSD, you'll get a 500GB SSD for free.

The PNY CS900 is an internal SATA III SSD, which means it needs to be permanently installed in your PC or laptop. But what you sacrifice in portability, you make up for in versatility. With read and write speeds of up to 550 and 515MB/s, respectively, you can quickly copy and transfer files between your main storage drive and external storage.

This bundle deal from Amazon includes two CS900 drives: one with 1TB of space, and the other with 500GB. The smaller drive is the perfect size to designate as the dedicated boot drive, storing essentials like your PC's operating system and your most-used programs and files. The 1TB drive is perfect as a main storage drive, with plenty of space for photos and videos, games, and documents.

Since the PNY CS900 SSDs use flash memory rather than physical disks, you'll get faster booting and loading times for your laptop and most-used programs and files. Flash memory is also ideal for stable, long-term storage of important data since, unlike traditional hard-disk drives, there aren't any moving parts you need to worry about getting damaged or causing data loss and corruption. 

The CS900 is designed to be power efficient as well, giving you better data performance and storage capacity without putting extra strain on your laptop's battery. Which is good news for gamers who have to deal with already less-than-impressive laptop battery lives, depending on their configuration.
