I lost 400 photos from a two-day shoot in 2019 because my single memory card glitched. Since then, I back up in the field. Every single time. No exceptions.

Here’s what I use and recommend.

SSDs vs Hard Drives

Portable SSDs have no moving parts. They’re fast, shock-resistant, and small. They also cost more per gigabyte. For field backup, the durability alone makes them worth the premium.

Portable HDDs spin metal platters. They’re cheap, high-capacity, and fragile. One good drop can kill them. Fine for your desk. Risky in a camera bag.

For field backup, buy an SSD. For archive storage at home, HDDs are fine.

Best Portable SSDs for Photographers

Samsung T9 (2TB) — ~$170

USB 3.2 Gen 2x2 with sequential read speeds up to 2,000 MB/s. Copying 64GB of RAW files takes under a minute. The rubber bumper provides decent drop protection, and it’s small enough to fit in a jacket pocket.

This is what I carry daily. Two years of heavy use with zero issues.

SanDisk Extreme Pro Portable SSD (2TB) — ~$160

Slightly slower at 2,000 MB/s read, but IP65 rated for water and dust resistance. The carabiner loop is genuinely useful — I clip mine to my bag. SanDisk’s reliability track record with photographers is excellent.

Samsung T7 Shield (2TB) — ~$140

IP65 rated, 3-meter drop resistant, and cheaper than the T9. Slower at 1,050 MB/s, which is still more than fast enough for backing up a day’s shoot. If you’re rough on gear, this one takes abuse.

Budget Pick: Crucial X9 Pro (2TB) — ~$120

No frills, solid performance at 1,050 MB/s. IP55 rating handles splashes and dust. This is the entry point for a quality portable SSD, and there’s nothing wrong with it.

Field Backup Workflow

Here’s how I handle backup during multi-day shoots:

  1. Shoot on two cards (if your camera supports dual slots) in backup or overflow mode
  2. At the end of each day, copy all cards to the portable SSD using a laptop or tablet
  3. Verify the copy — don’t just drag and drop and hope. Use software that verifies checksums (like FreeFileSync or TeraCopy)
  4. Keep the SSD and cards in different bags. If one bag gets lost or stolen, you still have a copy

For the truly paranoid (and I respect the paranoia): carry two SSDs and keep one in your hotel safe.

Card Readers Matter

Your backup is only as fast as your slowest component. A USB 2.0 card reader bottlenecks everything. Get a UHS-II capable SD reader with USB 3.0 or higher.

The ProGrade Digital SD/CFexpress reader (~$80) is the fastest I’ve tested. The Anker 2-in-1 USB-C reader (~$15) is a solid budget option for SD cards.

How Much Storage Do You Need?

Quick math: A 45-megapixel camera shooting uncompressed RAW produces files around 90MB each. A heavy day of shooting — 1,000 frames — creates roughly 90GB.

For a weekend trip: 500GB is tight, 1TB is comfortable. For a week-long project: 2TB gives you breathing room. For extended travel: Consider multiple 2TB drives.

The Rule of Three

Professional data preservation follows the 3-2-1 rule: three copies, two different media types, one off-site. For photographers, that looks like:

  1. Original memory cards (don’t format until you’re home)
  2. Portable SSD (field backup)
  3. Desktop drive or cloud (when you get home)

Your photos are your product. Protect them like they’re worth money — because they are.
