Most memory cards are anonymous slabs of black plastic that could roll off any factory line on any continent. Delkin’s new Valor Pro CFexpress Type B takes a different tack: it wears the American flag on its label, and the manufacturer says it is designed, assembled, and tested in the United States.
Patriotic branding aside, the interesting part is the performance. The Valor Pro is offered in a single 1TB capacity and carries a VPG800 rating, which guarantees a sustained minimum of 800 MB/s — the kind of floor that matters when you’re recording high-bitrate video and can’t afford a dropped frame mid-take.
Peak numbers climb considerably higher. Delkin quotes read speeds of up to 3,700 MB/s and write speeds up to 2,800 MB/s, with a 1,840 MB/s sustained write figure. That sustained write is arguably the headline spec here: burst speeds look great in marketing tables, but it’s the number a card can hold indefinitely that decides whether your camera keeps rolling or throws a buffer warning. At 1,840 MB/s, the Valor Pro has plenty of headroom for demanding 8K and high-frame-rate workflows.
CFexpress Type B remains the format of choice for pro mirrorless bodies and cinema cameras, and cards in this class are increasingly judged less on their top-line read numbers and more on how gracefully they handle heat and sustained throughput. Delkin’s VPG800 certification is a meaningful signal on that front, since it’s a standardized guarantee rather than a best-case lab figure.
- Capacity: 1TB
- Rating: VPG800 (800 MB/s sustained minimum)
- Read speed: up to 3,700 MB/s
- Write speed: up to 2,800 MB/s
- Sustained write: 1,840 MB/s
- Assembled and tested in: USA
The domestic-manufacturing angle isn’t just flag-waving. For studios, agencies, and government or defense contractors with sourcing requirements, a card assembled and tested stateside can tick boxes that an imported alternative simply can’t. For everyone else, it’s a talking point — and, presumably, part of the reason the pricing sits where it does.
The Valor Pro CFexpress Type B is priced at US$590 for the 1TB model and went on sale on July 1, 2026. That puts it firmly in premium territory, but for shooters who need certified sustained performance and a made-in-USA pedigree, it’s a distinctive proposition in a category where most rivals look — and are — interchangeable.
