External SSD vs External Hard Drive: Which to Get?

External SSD vs HDD compared on speed, price per TB and durability, and which suits backups, carrying files every day or video work.

In the external SSD vs HDD choice, an SSD is three to ten times faster and survives drops, while a hard drive (HDD) gives you far more space for the money. Pick an HDD for big, occasional backups and an SSD for files you carry and open every day.

The inside technology is the same as in laptops; SSD vs HDD explains how each works. Here’s what changes when the drive lives in your bag.

Speed difference you’ll notice

Drive	Typical real speed
Portable HDD	about 100–150 MB/s
Basic portable SSD	about 400–550 MB/s
Fast (NVMe) portable SSD	about 1,000 MB/s or more

Copying a 50 GB folder takes roughly 6–8 minutes on an HDD and 1–2 minutes on a basic SSD. Video editors can work straight off an SSD; off an HDD, footage stutters.

Fast SSDs need a fast port. On an old USB 3.0 port, even a 1,000 MB/s SSD tops out at about 400 MB/s; USB 2.0 slows any drive to a crawl. See HDD vs SATA SSD vs NVMe for more on speed classes.

Cost per terabyte

Hard drives are much cheaper per TB, and the gap grows with size. In Kenyan shops, a 1 TB portable HDD typically sells for around KES 6,000–9,500, while a 1 TB portable SSD usually costs about KES 13,000–20,000, with premium models higher. At 2 TB and above, HDDs are often half the price of an SSD or less.

Durability and size

HDDs have spinning disks. A drop while it’s running can kill the drive and your files.
SSDs have no moving parts, so they handle knocks, matatu rides and bag drops far better. They’re also smaller, lighter and silent.
Both should be kept away from heat and water, and both can fail without warning, so never keep your only copy on one drive.

Which for backups vs daily carry

Backups of a whole laptop, photos and films → HDD. Speed matters less when you back up once a week; follow how to back up to an external hard drive.
Carrying work between home, office and campus → SSD.
Video editing, game libraries for PS5 or PC → SSD.
Best of both → a small SSD for daily files plus an HDD at home for backups.

Test the capacity when you buy

Fake drives are common in town stalls and online marketplaces: they claim 1–2 TB but hold far less and quietly corrupt files once full. Unrealistically cheap “2 TB” pocket SSDs are a red flag. Buy from a shop that gives a receipt and warranty, check the brand and model on the maker’s site, and run a free capacity tester such as H2testw (Windows) before trusting the drive with anything important.
