Review: Toshiba Exceria Pro N502 SDXC UHS-II 128GB Memory Card Reviewed by: J.Reynolds Provided by: Toshiba
Welcome to Myce’s brief review of the super fast Toshiba Exceria Pro N502 SDXC UHS-II Memory Card. Does it deserve its reputation as one of the fastest SD cards around? Please read on to see what we found.
The Exceria Pro memory card implements the ‘UHS-II’ Ultra High Speed bus interface for SD memory cards.
UHS-II introduces a second row of pins on the SD and Micro SD memory cards (the first row of pins is retained to provide interoperability and backwards compatibility with existing non-UHS II devices).
Market Positioning and Specification
This is how Toshiba positions the Exceria Pro –
The test platform used was:
Workstation – Mobo: Asus Z170 Maximus VIII Extreme; CPU: Core I7-6700K (Overclocked to 4.9 GHz), Memory: 32GB Corsair Dominator Platinum 2400MHz, OS: Windows 10
The Workstation runs with an Overclock to 4.9 GHz, the C1E power state was disabled in the BIOS, and the High Performance Power Plan was engaged in Windows.
To test a UHS-II card one needs to use a UHS-II compatible card reader. We used an inexpensive ‘Integral’ USB3 device plugged into a native Intel USB3 port.
These are the results we achieved in some popular IO performance benchmarks –
You can see that in this benchmark we are hitting a top read speed of just over 250 MB/s and a top write speed of 213 MB/s, both of which are short of the specified speeds of 270MB/s and 260 MB/s.

… and a similar result when testing with Crystal Disk Mark.
… and AS SSD.
Note that Crystal Disk Mark and AS SSD both show excellent 4K Random IO results for a memory card.
For interest we also subjected the N502 to two of the ‘real world’ tests that we conduct when reviewing SSDs. In these tests we measure the time it takes to write a large amount of JPEGs to and from the card. Here are the results and comparisons with the results we have achieved with the SSDs –
Write JPEGs to the N502 –
Read JPEGs from the N502 –
You can see that the N502 is a lot faster than a typical HDD but is significantly slower than SSDs.
We have not achieved the speeds specified by Toshiba in any of our Windows based tests but it is easy for me to imagine that it could perform to that level in a UHS-II compatible professional camera.
The Exceria Pro N502 is undoubtedly a fast memory card that will meet or exceed the needs of any professional photographer. We could not find a price listed for the N502 in the UK. When it does appear we expect it will be pricey but nevertheless we also expect it will prove to be popular with photography professionals and enthusiasts.
I am pleased to award the Exceria Pro N502 memory card the Myce ‘Excellent’ rating.
