Best portable SSDs for iPhone

Top pick: Lexar Professional Go 1TB — USB 3.2 Gen 2 with reads up to 1050MB/s, and the "Go w/ Hub" kit adds the small hub that makes it genuinely useful on an iPhone: you can plug the drive into the phone and still charge or connect other gear. Fast enough for ProRes video straight to the drive, and small enough to live in a pocket.

Who the others suit:

• DigiEra 1TB Magnetic — sticks to the back of a MagSafe iPhone and is the quickest of the bunch (2000MB/s read), so it suits handheld shooting where you don't want a cable flopping around.
• Nusyn NSP33 1TB Magnetic — same magnetic idea, a calmer, simpler choice if you just want it to cling to the phone and disappear.
• Lexar SL500 1TB with Magnetic Set — a slim, well-known drive plus a magnetic mount; good if you'd rather have a mainstream brand and a mount you can move between devices.
• SanDisk Extreme 1TB — the rugged option: drop protection and a tougher shell for travel, card-holder use and outdoor shoots.
• Glyph Atom EX80 USB4 1TB — for people who also edit on a Mac or iPad and want the fastest desktop-class transfer, not just phone backup.

Two notes: the NEWQ fingerprint drive is USB-A only, so it needs an adapter on an iPhone, and the Samsung T7 listing is a refurbished unit — fine as a budget backup, less ideal as your main card.
