WD/ZDNETFollow ZDNET: Add us as a preferred source on Google.Amazon officially kicks off its Prime Day sale tomorrow, but if you're a bit disappointed in the early SSD deal offerings, Best Buy has you covered. Right now, you can save 56% on the WD Blue SN5100 SSD, bringing the price down to $300 (and much closer to pre-AI costs). And while it's designed with office work in mind, this SSD is just as useful for casual and semi-serious gamers.Also: The best Amazon Prime Day SSDs deals live nowAlong with 2TB of space, you'll get read and write speeds up to 7100 and 6700 MB/s, respectively.

And while the SN5100 is primarily intended for office work, gamers can also get a fair bit of mileage from it with faster read and write speeds than its predecessors and plug-and-play compatibility across desktops, laptops, and the PlayStation 5. That's why I gave this deal a 5/5 Editor's rating.
