Best Internal SSDs (NVMe / SATA)

Internal SSDs span a huge range — from cheap SATA upgrades for aging laptops to bleeding-edge PCIe 5.0 drives built for AI workloads. This roundup synthesizes what reviewers across RTINGS, Tom's Hardware, AnandTech, TechPowerUp, Wirecutter, and long-running r/buildapc and r/NewMaxx threads have said about the most-discussed drives currently shipping, weighted toward high-trust expert and specialist-community sources. Amazon rating volume is treated as a corroborating signal, not a verdict.

Across the reviewers we read, the WD_Black SN850X is treated as the default high-end PCIe Gen4 recommendation. Tom's Hardware and TechPowerUp benchmarks place it at or near the top of Gen4 random-read performance, and RTINGS-style endurance commentary in community threads notes its 1,200 TBW rating on the 2TB model is class-competitive.

Frequently asked

5 questions
Do I need a PCIe Gen5 SSD for gaming?
No. Across the reviewers we read, the consensus is that real-world gaming load times are virtually identical between a good Gen4 drive (like the SN850X or 990 Pro) and a Gen5 drive. Gen5 makes sense mainly for heavy content creation, large file transfers, or AI/ML workloads. DirectStorage benefits in games remain modest as of writing.
Which SSD is officially supported for PlayStation 5 expansion?
Sony's requirement is a PCIe Gen4 NVMe M.2 2280 drive hitting at least 5,500 MB/s sequential read, with a heatsink. The WD_Black SN850P is officially licensed by Sony, while the SN850X (with heatsink) and Samsung 990 Pro are the most commonly recommended unlicensed alternatives in r/PS5 threads.
Is a SATA SSD still worth buying in 2024?
Yes, but only for systems that lack an M.2 NVMe slot — primarily older laptops, older desktops, or as a secondary data drive. Reviewers consistently note that SATA tops out around 550 MB/s, so it's dramatically slower than NVMe, but it's still a massive upgrade over any spinning hard drive.
DRAM vs DRAM-less SSDs — does it matter?
For light gaming and general productivity, modern DRAM-less drives with HMB (Host Memory Buffer) like the WD SN7100 and Crucial P310 perform very close to DRAM drives in benchmarks reviewers have run. For sustained heavy writes or professional workloads, DRAM-equipped drives like the 990 Pro and SN850X pull ahead and run cooler under load.
How much SSD capacity do I actually need?
Community consensus on r/buildapc is 1TB as the practical minimum for a modern gaming PC, with 2TB now the sweet spot given that AAA games regularly exceed 100GB. Creators working with 4K video or large datasets typically want 2TB+ with high TBW endurance ratings.
