NVMe storage is fast enough now that the headline numbers blur together. What separates a good buy from a wasted one is matching the drive class to how you actually load and move files.

Quick Answer

A 1TB PCIe Gen4 NVMe drive (about R1,100 to R4,500) is the practical pick for South African buyers, hitting 5,000-7,000 MB/s read - enough that Gen5 gives no real-world gain unless you move huge files daily.

Capacity, DRAM Cache And Endurance

1TB is the sane floor now that game installs routinely pass 100GB; 2TB is the comfort pick if you keep a large library installed. Favour drives with a DRAM cache and a published TBW endurance rating for sustained work. A cheap DRAM-less drive is fine as bulk storage but feels slow under heavy writes.

Check The Slot Before You Order

Confirm your motherboard has a free M.2 slot at the right PCIe generation - a Gen5 drive in a Gen4 slot simply runs at Gen4 speed. Watch that adding a second M.2 does not disable a SATA port or share lanes with the GPU on some boards. A quick look at the manual saves a surprise on build day.

Gen4 Versus Gen5 In The Real World

A good PCIe Gen4 drive reads at 5,000-7,000 MB/s, which already loads games and projects faster than most people notice. Gen5 doubles the headline number and the price, but only large daily file transfers or pro video scrubbing feel it. For most builds, Gen4 is the smarter spend.

FAQ

Will any NVMe fit my board?

Check for a free M.2 slot at the right PCIe generation, and note that a second drive can disable a SATA port on some boards. A Gen5 drive runs at Gen4 in a Gen4 slot. The manual confirms it quickly.

Is PCIe Gen5 worth it over Gen4?

For most users, no - a good Gen4 drive at 5,000-7,000 MB/s already loads games and apps fast. Gen5 mainly helps large daily transfers and pro video work. Save the premium unless you need it.

How big an SSD should I buy?

1TB is the sensible floor with game installs over 100GB; 2TB suits a large installed library. A second drive for bulk storage is cheap. Match capacity to how much you keep installed.
