Storage is one of the most overlooked components in PC builds — until you're waiting 45 seconds for an application to load. Here's what you need to know.
The Three Tiers
NVMe PCIe SSD: The fastest consumer storage available. PCIe 4.0 NVMe drives hit 5,000–7,400 MB/s sequential read speeds. PCIe 5.0 doubles that. This is what your operating system and primary applications should run from.
SATA SSD: Still much faster than a hard drive (around 550 MB/s), but NVMe is now similarly priced so SATA SSDs are becoming less relevant for new builds. If you have an older system with no M.2 slot, SATA SSD is a worthwhile upgrade.
Hard Drive (HDD): The slowest option at around 150 MB/s, but the cheapest per gigabyte by far. HDDs are still relevant for bulk storage — archives, video libraries, backups — where speed doesn't matter much.
The Right Setup for Most Builds
The standard recommendation in 2026:
- Primary: 1TB or 2TB NVMe PCIe 4.0 — for OS, applications, and active projects
- Secondary: 4TB or 8TB HDD — for archives, media libraries, backups
This setup keeps your workflow fast where it counts (loading times, save speeds) while keeping bulk storage affordable.
Do You Need PCIe 5.0 NVMe?
Honestly, for most users: no. The real-world difference between a PCIe 4.0 and PCIe 5.0 NVMe in everyday tasks is nearly undetectable. PCIe 5.0 drives shine in large sequential transfers — moving huge video files or working with datasets. For gaming and general workstation use, save the money and get a larger PCIe 4.0 drive instead.
Storage in Nigeria: What to Expect
1TB NVMe PCIe 4.0 drives are widely available and well-stocked. Pricing is around ₦145,000 at Sephora Systems. HDDs from 2TB–8TB are reliable and affordable, making them the preferred archive solution. SATA SSDs are gradually being phased out in new builds.
