Sandisk launches CFexpress 4.0 Type B cards up to 4 TB and they're as expensive as predicted

Sandisk's new CFexpress 4.0 Type B tops out at 4 TB and $1,799: an eye-watering amount though it looks rather different once you do the per-TB maths.

Sandisk has announced three new professional memory card lines: the Extreme PRO CFexpress 4.0 Type B, and updated Extreme PRO SDXC UHS-II V90 and V60 cards with new 2 TB capacities and faster speeds across the board. In the context of what's been happening to memory card prices over the past six months, they're worth a closer look.

CFexpress 4.0 Type B

The headline product is the Extreme PRO CFexpress 4.0 Type B, which reaches up to 3700 MB/s read and 3500 MB/s write via a PCIe Gen 4 interface. This is roughly double the throughput of the previous CFexpress 2.0 generation. Capacities run from 128 GB up to 4 TB, though performance varies significantly depending on which you buy.

The 2 TB and 4 TB cards deliver the headline speeds with a minimum sustained write of 3100 MB/s and VPG1600 certification. The 1 TB model sustains 1950 MB/s writes with VPG1600 also confirmed. Drop to 128 GB or 400 GB (a capacity step appearing across multiple manufacturers' CFexpress 4.0 ranges) and sustained write falls to 900 MB/s. For anyone choosing a card to meet specific cinema camera VPG requirements, that split matters.

Sandisk has also added a SmartIdle feature to reduce thermal load during idle periods, and the cards are rated for drops of up to 5 m (16.4 ft) and bend forces up to 70 N. Pricing runs from $249 for the 128 GB to $1799 for the 4 TB. Yes, $1799.

$1799 for a memory card seems extortionate, but is positively bargain basement when measuring $/TB. The 4 TB card works out to $450/TB, while the 128 GB entry card is a steep $2000/TB, so there's a strong incentive to go large if your camera and your budget supports it.

The cards are due to be available in May.

V90 and V60 SD cards

The updated V90 brings 2 TB capacity to the SD format for the first time in this range, with read speeds of 310 MB/s and write speeds of 305 MB/s on 512 GB to 2 TB cards. Sandisk quotes over 1118 minutes of 8K/30fps footage on a single 2 TB card. The V90 is available now.

The V60 also tops out at 2 TB, with 300 MB/s read and 250 MB/s write on 256 GB to 2 TB capacities. It's aimed at prosumer and professional shooters capturing 6K video and high-resolution stills, and will be available in May.

V60 pricing ranges from $119 for 64 GB up to $1799 for 2 TB. V90 prices start at $239 for 128 GB and top out at $1999 for 2 TB.

The V60 and V90 entry prices are almost identical per TB (~$1,860 vs ~$1,867), which is a little surprising given the V90 is the higher-spec card. The premium for V90 over V60 essentially only shows at the top end: $1999 vs $1799 for 2 TB, a $200 difference for the step up to 8K-certified sustained performance. That's a pretty good deal.

The pricing context

These cards are arriving at an awkward moment for the professional memory market. Wholesale NAND and DRAM prices have more than tripled since September 2025, driven largely by AI infrastructure build-out consuming supply at a scale the memory industry wasn't designed for.

Late-2025 forecasts warned that a 512 GB CFexpress Type B card from the previous generation could hit $400–500 by mid-2026. The price is already at $380, and it's only April

Against that backdrop, Sandisk's new-generation pricing is not dramatically worse than those forecasts. Whether they hold through the year or start edging up themselves in turn is another question.
