The best way to improve the performance of an older PC or to expand the capacity of a newer one is a solid-state drive (SSD). SSDs are considerably faster than mechanical hard disk drives (HDD) and, as such, were traditionally more expensive. Prices have dropped over recent years, and now it's possible to buy 2.5-inch SATA and M.2 NVMe SSDs for less. During promotions such as Amazon Prime Day, which takes place July 11-12, some of the best SSDs on the market will be discounted, allowing you to buy more capacity at reasonable prices.

The retail giant won't be the only place to find deals these days, however, as other online stores have also announced similar promotions. We're continuously searching for the best SSD deals each day and will be updating this post with 2.5-inch and M.2 picks, as well as highlighting our favorite storage deals. Picking up a great discounted drive here would work well when taking advantage of the best Prime Day laptop deals.

FAQ

Q: How much should you spend?

The price of an SSD depends on its rated speeds, capacity, and form factor. 2.5-inch SATA SSDs are considerably less expensive than M.2 NVMe drives, but are often slower and require a place within the PC case for installation. The higher the speeds and capacity of a drive, the more expensive it will be. We'd recommend setting your budget accordingly.

Q: Should you buy an M.2 or 2.5-inch SSD?

The choice between an M.2 NVMe SSD and a 2.5-inch SATA SSD depends entirely on what your PC supports. Most modern motherboards will have at least one M.2 slot, which can take an M.2 SSD. Doing so saves space inside the PC case by removing both the SATA and power cables required by 2.5-inch drives. They're also considerably fast, but more expensive. Want the highest capacity for the lowest price? Go with a 2.5-inch drive. Want the best performance and save space? M.2 drives are for you.

Q: What makes a good deal?

You will only find SSD deals here that are worth considering. We've seen retailers in the past artificially inflate prices of products ahead of discounts to make it seem as though the deal is new. We make sure the discounts we cover here at XDA-Developers are deals we'd consider buying ourselves. You can check prices yourself by using tools such as CamelCamelCamel.
