SSD and HDD Buying Guide
Looking to upgrade your storage? Here are some things to keep in mind:
Internal SSDs and HDDs come in several form factors, with the most popular now being the M.2 "gumstick" variety, although 2.5-inch drives still have plenty of use cases. Typically, solid-state drives have more variance because they don't require a mechanical spool. Make sure that the model you're purchasing will fit in your machine — consult the manual or the manufacturer's website for specifications.
Storage drives also use a number of different interfaces, and compatibility is important there as well. The two primary options are SATA and PCIe, each with advantages and disadvantages. In addition, the data transfer protocol is also different between units. Make sure they match.
Performance-wise, two factors matter: size and speed. Both increase cost, so balancing your budget with how much space you want is key. Thankfully, drive prices are lower than ever when you consider how capacious they are, so you can get massive multi-terabyte drives for pretty cheap.
Frequently Asked SSD and HDD Questions
How Do I Know What SSD I Should Get?
The sheer variety of solid-state drives on the market can be overwhelming. Purchasing with purpose is the way to get the best value moving forward. If you're moving files between locations, you obviously need an external SSD. If you plan to build a desktop that keeps system files on an SSD and program files on an HDD, a smaller solid-state drive will be more cost-effective. If you need to store massive amounts of data on a budget, an HDD will be the best option.
Which SSD Is Better, SATA or NVMe?
The major difference in solid-state drives is their interface method. Serial ATA technology is older and works like traditional mechanical drives, while Non-Volatile Memory Express was designed to work exclusively with SSDs. NVMe uses the PCIe bus, which is being regularly updated and expanded to exploit additional lanes of data transfer, increasing speed and capacity with each generation. NVMe will generally provide better results, but SATA may be compatible with more systems.
How Big of an SSD Do I Really Need?
As the great computer scientist Tupac Shakur famously said, "Only God can judge you." We're proponents of investing a little extra than you think you need to for a more spacious drive. Given the skyrocketing sizes of file installs, with some AAA games coming in at over 100GB, you'll find whatever drive you buy filling up fast. It's smart to future-proof your setup now instead of buying a patchwork of external storage later.
