'ZDNET Recommends': What exactly does it mean?
ZDNET's recommendations are based on many hours of testing, research, and comparison shopping. We gather data from the best available sources, including vendor and retailer listings as well as other relevant and independent reviews sites.

Get a 1TB and 500GB PNY CS900 internal SSD for $80 at Amazon during the Big Spring Sale
Amazon is offering a great deal on storage right now during their Big Spring Sale: 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.
How I rated this deal:
While these aren't the highest-capacity SSDs you can find, they're a great way to add extra storage to budget-grade office and gaming laptops as your needs change. You'll also get 1.5TB of storage for the price of 1TB, making this deal a great value for any DIY PC modder who likes to run dual boot and storage drives.
When will this deal expire?
The Amazon Big Spring Sale started on March 25 and will run through March 31. While Amazon hasn't put a countdown timer or any other indication of a hard-and-fast end-date for this PNY CS900 SSD bundle deal, you won't want to wait around to take advantage of this discount. Amazon and PNY may only have a certain number of units available for this bundle or at this price. This means the sale may end when a certain number of SSDs are bought. And with 1.5TB of storage for the price of a single SSD, you might not see another bundle deal this good until Black Friday.
