We are currently in the midst of Amazon’s Big Spring Sale. It’s a major sales event for the retailer, where it rolls out huge discounts on a variety of products, from smartphones to laptops and TVs. Now is one of the best times to upgrade your storage setup, as you’ll find great deals on external storage drives. As it so happens, I have a great one for you.

Right now, the Western Digital 2TB WD Red SA500 NAS SSD is on sale for $450, a 35% discount off its original $670 price tag. Multiple models of this Western Digital SSD have seen a similar price drop, though the best option still goes to the 2TB model.
This is a niche product. The Western Digital WD Red SA500 NAS 3D NAND Internal SSD is meant specifically for homes or businesses with an NAS system.
You may be wondering, “What is an NAS?” NAS stands for Network-Attached Storage, and it’s essentially a mini network server. It can store gigabytes of documents, photographs, videos, programming projects, and more. These can be handy devices if you frequently work with a lot of files and you need an external repository.

This Western Digital NAS SSD that I’m recommending is like a mini-server. It boasts lightning-fast read and write speeds, allowing users to save and access files in almost no time. The drive actively reduces latency and boosts responsiveness for OLTP (online transaction processing) databases. It supports heavy multi-user environments. User reviews in the Amazon listing praise the SSD for its high-speed performance. People also enjoy how easy it is to install. If you have a slot open in your NAS server, you just slide it into the space.
How I rated this deal
As per ZDNET’s rating system, I give this deal a 4/5. That rating is only for the 2TB model. The deal on the 500GB SSD gets a 3/5 rating, while the 1TB option gets a 2/5 rating. Not bad all around. I would definitely recommend this particular drive to anyone who owns an NAS in their household or business. It’s a great way to store large files away from your devices. The internal drives on your PC, tablet, or phone will remain clutter-free.
