In recent months, we have completed a few articles on ProGrade Digital storage devices, as well as their card readers. Our first report was on the 1700 Gold and Cobalt CFExpressB Memory Cards along with their Thunderbolt 3 Dual CFExpress Card Reader, which is posted here, We next covered their 1700 Cobalt 650GB CFExpressB Card with their Dual Slot CFExpress/SD Card Reader, which is posted here. On the Test Bench Today, we have the ProGrade Gold 256GB V60 MicroSD Memory Card, and with that, they also sent along their Dual MicroSD Card Reader. Check out ProGrade’s website here.
We have kind of grown attached to these readers for several reasons, the first of which is each utilizes Type-C connectors to get the top possible speed from the drive being read. While we can bring in speeds of 1700MB/s with CFExpress Type B, many might be surprised that the MicroSD Gold cards we are testing today will also reach 280MB/s when being read in that top reader. Something I also like is the fact that the base of each is magnetic so they are stackable as shown in this shot.
The ProGrade Gold MicroSD V60 Card is available in 64, 128 and 256GB capacities and has a video rating of V60 which means that it will maintain a sustained video write speed of 60MB/s…which actually brings us into the 8K recording area. It is also Class 10 U3 and these can be understood through this chart from the SD Association which regulates such cards:
The ProGrade Gold 256GB V60 MicroSD card we are testing today has performance specifications of 250MB/s read and 140MB/s write, has been optimized for 4K and comes with a 3-year limited warranty.
ProGrade MicroSD cards come with an adapter that will allow full speeds to be realized, whether using the card in its larger or smaller format. This can be seen with the additional contacts on the back of both the card and adapter.
Checking Amazon, we can see the 256GB version of the proGrade Gold V60 MicroSD that we are testing today at $54.99. Also worthy of mention and looking at the back of the MicroSD card above, we see that each card includes an etched serial number for security purposes.
Let’s take a look at some benchmarks on the next page…
