The Toshiba Exceria Pro is the flagship UHS-I U3 SD memory card by Toshiba.
Toshiba cards are not that popular in western markets but they are pretty standard in Japanese markets. This card is difficult to find but it’s a very good card although a bit older now, at least the one I still have. I can’t find new ones to test.
Toshiba Exceria Pro U3 Review
When benchmarking the Toshiba scored a read speed of 97.8 MB/s and a write speed of 74.7MB/s. This is a little bit below average for flagship UHS-I cards based on today’s tests and I would say this card sits somewhere in between a super-fast card, like a Sandisk Extreme Pro, and a mid-range card like the Sandisk Extreme.
The card is only rated for a 75MB/s write speed and 95MB/s read speeds so these scores we are seeing are very close to spec, which is what we like to see.
Memory card speeds were tested in a Sandisk UHS-II USB-C memory card reader using Crystal Disk in Windows 10.
| Card Name | USB-C Read | USB-C Write |
| Toshiba Exceria Pro U3 | 97.8MB/s | 74.7MB/s |
Will It Work For 4k Video?
The Toshiba is rated at a U3 rating, which means it has a guaranteed minimum write speed of 30MB/s. When you convert that to Mbps we see that the card is able to maintain a guaranteed data stream of 240mbps. Which is fine for a lot of today’s cameras 4k outputs.
Some cameras like Fujifilm are offering 4k at 400Mbps, but usually, they have a lower bitrate option as well, and this goes for mosts camera brands.
