Nextorage Introduces a New Series of SD Cards
Japan-based Nextorage, a startup founded in 2019 by ex-Sony memory and storage division engineers, has introduced two new SD card models: the NX-F2PRO SD, aimed at the best performance, and the NX-F2SE cards, slower but still capable of handling 4K video capture.
The NX-F2PRO cards are Nextorage’s fastest, with maximum rates of 300 MB/s read and 299 MB/s write, which the company claims are close to the UHS-II standard’s limit. To achieve these results, the cards feature a pSLC NAND memory implementation. They are V90 compliant (a minimum guaranteed speed of 90 MB/s), allowing them to record up to 8K films with stability and keep up with high-speed continuous photo shooting.
Such speed limits the overall storage capacities available, as the NX-F2PRO line has three options for relatively modest total storage: 64 GB, 128 GB, and 256 GB.
Nextorage slows performance somewhat to increase capacity. The NX-F2SE series comes in capacities of 128 GB, 256 GB, and 512 GB but only claims V60 speeds – a minimum guaranteed speed of 60 MB/s — which, while slower, is generally fast enough to handle most 4K cameras that shoot to SD cards. However, Nextorage does not specify how quickly their NXF2SE series can write data to the card, yet it is mentioned in the specs. The 128 GB card has a maximum transfer rate of 100 MB/s, while the two larger capacities have a maximum transfer rate of 170 MB/s.
The cards have been tested to survive 10,000 insertions into a reader or camera and are dustproof (IPX5) and waterproof (IPX7). The cards also come with a five-year warranty. Nextorage, like ProGrade Digital, has the opportunity to download and use “Memory Card File Rescue” software, which can restore data that has been mistakenly destroyed.
Nextorage has not disclosed how much the cards will cost, but they will be available on Amazon beginning in April.
