How to compare NVMe SSDs for 4K video editing without chasing hype

Quick Answer

Capacity matters, but the right tier matters more: a single 1TB Gen4 NVMe drive covers the vast majority of SA buyers needing storage for 4K video editing without chasing hype. Expect roughly R1,300 to R1,900 for a quality 1TB Gen4 stick and around R2,400 to R3,400 for 2TB. Buying beyond 2TB rarely pays off unless your library genuinely outgrows it.

How much capacity 4K video editing without chasing hype actually needs

Map storage to what you keep installed, not what could theoretically fit. A modern AAA title runs 80-150GB, Windows plus drivers eats roughly 40GB, and a working set for 4K video editing without chasing hype adds its own footprint. Most SA buyers land comfortably on a 2TB Gen4 drive; a 1TB drive only makes sense once you juggle many large installs at once. Sequential reads on a good Gen4 stick sit around 5,000-7,000 MB/s, but for this workload sustained write speed and the SLC cache size matter more than the headline read figure.

Gen4 vs Gen5, and where the rand stops paying back

A Gen4 NVMe (PCIe 4.0) is the sweet spot for 4K video editing without chasing hype. Gen5 drives push past 12,000 MB/s but cost noticeably more, run hotter, and the real-world difference for this use is small: game loads and file copies feel near-identical to Gen4 day to day. Spend the saved R800-R1,500 on more capacity or a drive with DRAM cache and a 5-year warranty instead. Confirm your motherboard has a free M.2 slot at the speed you are paying for before you commit.

FAQ

Is a 1TB or 2TB NVMe better for 4K video editing without chasing hype in South Africa?

For most SA buyers a 1TB Gen4 drive (around R1,300-R1,900) is enough, while a 2TB drive (R2,400-R3,400) suits anyone keeping many large installs at once. Pick 2TB only if you regularly run out of space, not as a default.

Do I need a Gen5 SSD or is Gen4 enough?

Gen4 is enough for 4K video editing without chasing hype; it already delivers 5,000-7,000 MB/s and load times feel near-identical to Gen5 here. Gen5 mainly helps niche pro workloads and costs more while running hotter.

Does an NVMe drive need a heatsink?

Gen4 drives usually run fine on the motherboard's M.2 heatsink. A bare Gen5 stick benefits from a dedicated heatsink to avoid thermal throttling under sustained writes, so check what your board includes.
