Storage is the one thing you shouldn’t cheap out on
Hard drives fail. SSDs wear out. SD cards corrupt at the worst possible time. In South Africa, add load shedding to the mix – unexpected power cuts dramatically increase the risk of data corruption and drive failure.
Here’s how to choose storage that won’t let you down.
HDD vs SSD: the short version
| Feature | HDD | SATA SSD | NVMe SSD |
|---|---|---|---|
| Speed (read) | 100-200 MB/s | 500-550 MB/s | 3,000-7,000 MB/s |
| Speed (boot time) | 30-60 seconds | 10-15 seconds | 5-8 seconds |
| Capacity | 1-20 TB | 250GB-8TB | 250GB-4TB |
| Price per TB | R300-R500 | R800-R1,500 | R1,500-R3,000 |
| Load shedding risk | High (moving parts) | Low (no moving parts) | Low (no moving parts) |
| Lifespan (typical) | 3-5 years | 5-10 years | 5-10 years |
| Best for | Archives, backups, CCTV | Laptops, desktops, general use | High-performance work, gaming |
For your boot drive: SSD or NVMe only. No exceptions. The speed difference is night and day.
For bulk storage: HDDs are still the most cost-effective per terabyte. Use them for archives, backups, and CCTV footage.
SSD types explained
SATA SSD (2.5″ form factor)
The standard SSD. Fits in any laptop or desktop. 500-550 MB/s read speed. Good enough for 95% of users. Prices start around R500 for 250GB.
NVMe SSD (M.2 form factor)
Plugs directly into the motherboard. 5-14x faster than SATA SSDs. Required if you work with large files (video editing, databases, virtual machines). Prices start around R700 for 250GB.
PCIe 5.0 NVMe (latest gen)
Absurdly fast (up to 14,000 MB/s) but overkill for most people. Only useful for extreme workloads. Expensive and runs hot.
For CCTV: what drive do you need?
CCTV recording is 24/7. A standard desktop drive will die within 1-2 years under that workload. You need a surveillance-rated drive:
| Drive | Capacity | Cameras supported | Price range |
|---|---|---|---|
| WD Purple 1TB | 1TB | 1-4 cameras | R800-R1,000 |
| WD Purple 4TB | 4TB | 4-8 cameras | R1,500-R2,000 |
| WD Purple 8TB | 8TB | 8-16 cameras | R2,500-R3,500 |
| Seagate SkyHawk 4TB | 4TB | 4-8 cameras | R1,500-R2,000 |
| Seagate SkyHawk 8TB | 8TB | 8-32 cameras | R2,800-R4,000 |
WD Purple and Seagate SkyHawk are designed for always-on recording. They handle the constant write workload and have firmware optimised for video streaming. Standard desktop drives are not built for this.
For NAS: building your own cloud
A NAS (Network Attached Storage) is a personal cloud that lives in your home or office. It backs up your devices automatically, stores your files centrally, and gives you access from anywhere.
How many drives?
- 1 drive – Basic file storage. No redundancy. If the drive fails, your data is gone.
- 2 drives (RAID 1) – Mirror. One drive fails, the other has an exact copy. Minimum for data you care about.
- 4 drives (RAID 5) – One drive can fail without losing data. Best balance of capacity and safety.
- 4+ drives (RAID 6) – Two drives can fail simultaneously. For business-critical data.
NAS drive recommendations
Use NAS-rated drives. Desktop drives in a NAS vibrate more, run hotter, and fail faster.
| Drive | Capacity | Workload rating | Price |
|---|---|---|---|
| WD Red Plus 2TB | 2TB | 180TB/year | about R900 |
| WD Red Plus 4TB | 4TB | 180TB/year | about R1,600 |
| Seagate IronWolf 4TB | 4TB | 180TB/year | about R1,500 |
| Seagate IronWolf 8TB | 8TB | 180TB/year | about R3,000 |
Load shedding and your drives
Power failures are the number one cause of premature drive failure in South Africa. Here’s how to protect your storage:
- Always use a UPS. For desktops, a basic 600VA UPS (R500-R800) gives you enough time to save your work and shut down properly. For NAS, the same UPS keeps it running through 2-hour outages.
- Enable write caching on your NAS. Most NAS systems have a setting to flush data to disk less frequently. This reduces the number of write operations during unstable power.
- Consider an SSD boot drive for your PC. SSDs don’t have moving parts. A sudden power loss is far less likely to corrupt an SSD than an HDD.
- Use RAID 1 for important data. If one drive dies from a power surge, the mirror has your data.
- Replace drives proactively. If a drive is more than 3 years old and you’re in a high-load-shedding area, replace it before it fails. The cost of a new drive is less than the cost of data recovery.
Backup: the rule of 3-2-1
If your data exists in only one place, it doesn’t exist. Follow the 3-2-1 rule:
- 3 copies of your data
- 2 different types of storage (e.g., internal drive + external drive)
- 1 off-site backup (cloud or another physical location)
For most people: your PC has the original, a NAS or external drive has the second copy, and Google Drive/OneDrive/Backblaze has the third.
