The 9 Best SD Cards For 8K Video

The Kingston Canvas React Plus is a full-size V90 card, so it promises steady writing fast enough for compressed 8K. It writes a little faster than Kingston's own rating, and this size comes at a fair price for a V90 card. A lifetime limited warranty backs it, and it claims to shrug off water, heat, cold and airport X-rays. The catch is room: 128GB holds only a little over half an hour of 8K.

Built for heavy video, the SanDisk Extreme PRO V90 is the V90 version of SanDisk's best-known pro card, rated to read and write at the same high speed. Shop carefully, since an older, slower V60 version looks almost the same. SanDisk claims it survives water, dust and long drops, and it comes with two years of free software for recovering deleted files. It costs a lot per gigabyte, and supply was thin at last check.

The PNY EliteX-PRO90 posted the fastest writes in Alik Griffin's V90 tests, a touch under its own rating. This size holds a bit over an hour of 8K at a fair price per gigabyte. PNY, better known for everyday storage, says the card resists magnets, shock, heat and water, and it carries a lifetime warranty. With fewer owners, there's less long-term feedback, and in an older camera slot it slows down.

A company that builds only cards and readers for photo and video work makes the ProGrade Digital V90 Iridium. ProGrade says each card is fully tested, and its paid software can check a card's health and restore its speed. This 128GB size writes more slowly than the larger ones, though still well past what 8K needs. The warranty is listed as three years in one place and lifetime in another, so confirm the terms.

Camera bags have carried the Lexar Professional 2000x for years, and Lexar prints 8K right on the box. It's a V90 card that writes well past what compressed 8K needs and holds a steady pace on long clips. Lexar publishes a compatibility guide for the major camera brands, and a limited lifetime warranty backs it. It writes somewhat below its rated speed, and the label design is changing, so yours can look different.

From Delkin Devices, a San Diego camera memory maker, the Delkin Power SD card is a V90 card whose real writing speed lands right at its rating. A lifetime warranty and a 48-hour replacement promise for factory defects matter on a working shoot. Delkin lists it for 8K and 360-degree video, and for cameras such as the Canon EOS R5 and Nikon Z8. It's pricey per gigabyte, and only a few were in stock at last check.

Few microSD cards are rated V90, and the Delkin Power microSD is one, with an extra row of contacts for full speed in a UHS-II slot. That suits drones and small rigs that shoot heavy video, though an older slot slows it down. An adapter fits it to full-size slots, and Delkin's lifetime warranty applies. It tops out at 64GB, under 20 minutes of 8K, and no outside speed test turned up.

Many action, 360-degree and drone cameras are built around the SanDisk Extreme microSD, an everyday card rated V30. Those cameras record 8K in much smaller files than a mirrorless body, so this class of card is enough. Check your camera's manual first, since some modes need V60 or faster. This large size is cheap, and it's sold almost everywhere. It can't keep up with 8K on a mirrorless or cinema camera.

When card size matters more than brand history, the Sabrent Rocket V90 is worth a look. This 512GB card holds about two and a half hours of 8K at a low price per gigabyte. Sabrent, better known for fast computer drives, lists it for Canon, Nikon, Panasonic and Sony bodies. No independent test has checked its speed, the warranty is short at one year, two if you register, and the upfront price is high.
