ProGrade Gold MicroSD UHS-II V60 Memory Card and Reader Review


ATTO Disk Benchmark is perhaps one of the oldest benchmarks going and is definitely the main staple for manufacturer performance specifications. ATTO uses RAW or compressible data and, for our benchmarks, we use a set length of 256mb and test both the read and write performance of various transfer sizes ranging from 0.5 to 8192kb. Manufacturers prefer this method of testing as it deals with raw (compressible) data rather than random (includes incompressible data) which, although more realistic, results in lower performance results.


Crystal Disk Benchmark is used to measure read and write performance through sampling of random data which is, for the most part, incompressible. Performance is virtually identical, regardless of data sample so we have included only that using random data samples.




Anvil’s Storage Utilities (ASU) are the most complete test bed available for the solid state drive today. The benchmark displays test results for, not only throughput but also, IOPS and Disk Access Times. Not only does it have a preset SSD benchmark, but also, it has included such things as endurance testing and threaded I/O read, write and mixed tests, all of which are very simple to understand and use in our benchmark testing.


TxBench is one of our newly discovered benchmarks that we works much the same as Crystal Diskmark, but with several other features.  Advanced load benchmarking can be configured, as well as full drive information and data erasing via secure erase, enhanced secure erase, TRIM and overwriting.  Simply click on the title for a free copy.


ProGrade Digital has thrown alot at us in the past few months and we have to admit, their gear is just that good.  It is the gear used and trusted by media professionals. Their card readers have an amazing build quality to them and all are capable of returning top speeds regardless of the media used.

Today, we looked at their 256GB GoldMicroSD V60 memory cards and they returned speeds of 280MB/s read and 140MB/s write, well above posted specs.  In addition, their Dual MicroSD Card reader has shown itself to be yet another high quality reader to add to our ProGrade Collection.

I guess when it comes down to it, we simply have to ask ourselves what gear we find ourselves using in our digital cameras, drones, webcams, security systems, trail cams, and so on.  ProGrade Digital has our vote.

  1. Wow. I visited their website, and found this very interesting information here:

    Our microSDXC memory cards include everything you need for uninterrupted high-speed photography and video capture – including Refresh Pro. Refresh Pro performs two key functions: health monitoring and sanitizing. The health function measures the overall health of the memory card and provides feedback on the remaining life of the flash memory. The sanitize operation performs a deep clean, restoring the memory card to its original factory performance. Sanitize has been a function of CFast(TM) cards since they were introduced and ProGrade Digital now brings this functionality to SDXC(TM), microSD(TM), and CFexpress (TM) cards. ”

    I guess Refresh Pro software is provided with the purchase of their cards. It is a nice feature though:

    There are 3 testimonials near the bottom of of the page in the first link I provided. The one by Kennith W. is quite telling about how robust the construction and quality of these cards are.

    Les, you have the price of the 128 GB card listed, not the 256 GB card.

    As always, great review. I appreciate that you add the SD Association chart with your SD reviews, as their different classes are confusing.

    If you need the best, ProGrade would be about impossible to beat.

    Maybe you could add a new Review category for MicroSD, SD and CFExpress cards and card readers, as this category has become more important to everyone in the past couple of years due to all of the growth of electronic devices that depend on them.

    Thanks for the review, Les. I probably would not have heard of this company it weren’t for you.

    • We are working with Refresh Pro and Recovery Pro now and I may amend th article. As for the links, the 256GB is not avail so it is defaulting to the $128GB. Tx ahead.

  2. I’m glad you’re testing Refresh Pro and Recovery Pro. I’m interested in learning about this software. If you do amend this article, would you please note at the top of the article that it has been updated? That way I’ll know to re-read it.

    Thanks, Les

    BTW, have you heard any rumors about any new/future technology for SD/MicroSD cards that might improve their speeds, especially in RND4K Q1T1? I realize that the overall quality and reliability has steadily improved over the years, but it would be nice to see transfer speeds of small file sizes increase.
