Quick Answer
For South African buyers, an NVMe SSD is the clear winner over SATA SSDs and hard drives for your boot and game drive: a 1TB Gen 4 NVMe (around R1,500) reads at 7,000MB/s versus SATA's 550MB/s. Keep a SATA SSD or hard drive only as cheap bulk storage for archives, where capacity per rand matters more than speed.
NVMe versus SATA versus HDD
An NVMe SSD is roughly 12 times faster than a SATA SSD for sequential reads and far quicker at small-file access, which is what speeds up Windows and game loading. A SATA SSD (around R900 for 1TB) still beats a hard drive comfortably. A hard drive only makes sense for large, rarely-accessed archives where the lower cost per terabyte wins.
Where each type fits
Use a 1TB Gen 4 NVMe for Windows and your main games, a 1TB or 2TB SATA SSD for a second library, and a hard drive only for backups and media you rarely touch. This tiered setup gives the best balance of speed and capacity per rand for a South African gaming or work build.
What to check before buying
Confirm your motherboard has a free M.2 slot for NVMe, and prefer drives with a DRAM cache for consistent performance when the drive fills up. For Gen 5 drives, a heatsink is needed since they run 70C to 90C. DirectStorage support helps load times in newer games.
FAQ
Is NVMe much faster than SATA?
Yes. A Gen 4 NVMe reads at around 7,000MB/s versus SATA's 550MB/s, roughly 12 times faster for sequential transfers and quicker at small-file access. This speeds up Windows and game loading noticeably.
Should I still use a hard drive?
Only for large, rarely-accessed archives where the lower cost per terabyte wins. For Windows, games, and apps, an NVMe or at least a SATA SSD gives a far better experience.
How much storage do I need?
Aim for at least a 1TB NVMe for Windows and main games, since modern titles need 80GB to 150GB each. Add a SATA SSD or hard drive for a second library if you keep many games installed.
For your main drive at Evetech, choose a 1TB Gen 4 NVMe with DRAM cache; add a cheaper SATA SSD or hard drive only for archives where capacity per rand matters most.
