Whether you're a videographer moving 4K footage, a student backing up a thesis, or a family safeguarding photos against load shedding power surges — you need portable storage. The three options look similar on a shelf but behave completely differently. Here's the honest comparison.
The three options, head to head
| Flash drive | External HDD | Portable SSD | |
|---|---|---|---|
| Typical read speed | 30–150 MB/s | 100–140 MB/s | 1000+ MB/s |
| Copy a 50GB video project | ~15–30 min | ~7 min | under 1 min |
| Survives a drop? | Usually | Often fatal — spinning parts | Yes — no moving parts |
| Best use | Documents, printing shops | Bulk cold backups | Daily work, video, photos, game libraries |
Why SSDs win for anything that matters
Speed you feel. At 1000MB/s+, a portable SSD is fast enough to edit video directly off the drive — no copying to your laptop first. For photographers shooting weddings or agencies juggling client files, this changes the daily workflow, not just the backup routine.
Durability you need. Hard drives die when dropped; it's a matter of physics. SSDs have no moving parts — they shrug off the bumps of a laptop bag on a Gautrain commute.
Phone compatibility. Modern portable SSDs plug into USB-C phones directly. Film on your phone, offload to the SSD on the spot, keep shooting — no laptop needed in the field.
The two SSDs we stock
MoveSpeed WD10 512GB — R1,725
Pocket-size, 1000MB/s reads, works with PC, Mac and smartphones. The sweet spot for students, office workers and anyone who wants fast, reliable everyday storage. 512GB holds roughly 100,000 photos or 25 hours of 4K footage.
MoveSpeed GD10 Touch Screen — R3,199
The step-up: 1050MB/s reads and a built-in touch screen showing capacity and transfer status at a glance. For video editors, content creators and professionals who live out of their drive.
A South African note: load shedding and your data
Sudden power cuts mid-write are how files corrupt and drives die — especially spinning hard drives. A portable SSD finishes writes in a fraction of the time (smaller window of risk) and, used with a laptop, rides on the laptop's battery through the outage. If your backup strategy still depends on a desktop external HDD, load shedding is quietly stacking the odds against you.
Frequently asked questions
Is 512GB enough?
For documents, photos and general backup — comfortably. For ongoing 4K video work, consider the larger GD10.
Do these work with iPhone?
USB-C iPhones (15 and later) connect directly. Older Lightning iPhones need an adapter.
Do they need a power supply?
No — both draw power from the device they're plugged into.
Delivery?
Tracked courier, 2–5 working days nationwide, free on R750+ orders — both SSDs qualify.
