Kingston MobileLite Plus USB 3.2 microSDHC/SDXC UHS-II Card Reader (MLPM)

The media could not be loaded. In order to utilize USB 3.2 speeds, you must not only have a computer or laptop that supports that connection, but also your SDcard must be able to even read/write at that speed. My SDcard has a max write of 130mb/s and at the write speed of 90mb/s that's about 69% write speed. This is pretty good given it was on a 3.0 USB connection. You can see in the video I transferred about 1.7 Gig video and it took less that 30 seconds. I did transfer up to 30 gigs in the same folder and it came out to roughly 10 minutes. This is a great reduction from my old card reader which took about 1hr 30minutes for 64 gigs; this card reader does it job.

I have tried multiple USB 2.0 card readers, which maxed at about 40mb/s. I have also tried the ever so popular Transcend USB 3.1 Gen 1(USB 3.0) MicroSD/SD Card reader, but that maxed out at 95mb/s. At first, I thought perhaps it was my MicroSD cards....because there are TONS of fakes that float around branded with the Big brand names in the space(SanDisk, Samsung, Lexar, Delkin), on top of that companies often over exaggerate the claims of read and write speed on all types of storage, SD/MicroSD cards are no different.After attempting to benchmark multiple ways my SanDisk Extreme (UHS-I/U3/A2/C10/V30) 64GB card with the Transcend USB 3.1 Gen 1 card reader, only to get MAX results of 95mb/s sequential read I then went on to some other cards...they all had one thing in common...95mb/s was the max. Was it just the most popular max sequential read speed? While it is a popular speed reading, since most cards nowadays are advertised as having a read speed of 100mb/s, that wasnt the reason for my cards maxing out at the speed.These are the cards I tested:-SanDisk Extreme (UHS-I/A2/U3/V30/C10) 64GB- Lexar Professional (UHS-I/A2/U3/V30/C10) 128GB-Lexar Performance (UHS-I/A1/U1/V10/C10) 32GB-Samsung Evo Plus (UHS-I/U1/C10) 32GB-Samsung Evo Select (UHS-I/U1/C10) 32GB-Kingston Canvas Select Plus (UHS-I/U1/A1/V10/C10) 32GBAll these cards are rated for a maximum of at least 100mb/s sequential read speed, with varying write speeds. HOWEVER, the SanDisk extreme is rated for 160mb/s sequential read, so when my Transcend card reader returned a 95mb/s read, AND an as advertised 60+mb/s write for the SanDisk extreme, I began to wonder if the speed bottleneck was my card, computer or card reader. I tested all my other cards, to find that no card could surpass the 95mb/s speed, even though other cards were rated for 100mb/s and had reviews with 98mb/s(Lexar Pro/Lexar Performance). I then looked at the reviews of the Transcend card reader and sure enough, there was not a single review from those who posted screen shots from Crystal DiskMark, BlackMagic, h2testw or any other benchmarking software that surpassed 95mb/s!!! I knew I had identified the problem, the card reader!It was at that point that I filed for a return of the Transcend card reader, and ordered this Kingston USB 3.2 Gen 1 UHS-II card reader. The most important thing about this card reader that should be considered is NOT the USB 3.2 Gen 1, because thats the SAME specs as USB 3.0 and USB 3.1 Gen 1. The most important thing is that it is rated for UHS-II cards: that mean it can handle UHS-II speeds, which should theoretically get rid of the bottleneck problem I was previously facing.Well, I am happy to report, it absolutely did its job. This card reader blew away the speeds of the most popular card reader currently on Amazon (Transcend). I was able to clock 183mb/s on my SanDisk Extreme in Sequential read, and 68mb/s in sequential write...both of which OUT PERFORM the advertised specs of the 64GB card(160/60), a far different outcome from what I previously thought (a fake card or boastful but false specs).I HIGHLY suggest this card reader for EVERYONE who wants to test the TRUE speed of their high end UHS-I cards, I havent found anything that performs as well as this reader.

So far this adapter works. I was able to use it to get RPIos flashed using Rufus on a microSD card. I haven't tested the speeds cause lets be real, a microSD card is not a NVME drive. You're never going to get 1GB/s read/write speeds from an SD card, but this device isn't holding back the read/writes either. If you need a microSD card reader this gets the job done.

Most memory card readers that come bundled together with your MicroSD cards are slow (around 30MB/s for copying data to your computer). This Kingston MicroSD card reader greatly improves read performance when copying files from MicroSD cards (I get speeds of up to 150MB/s). Highly recommend for content creators.

I use micro sd cards as "memory cards" for my Raspberry Pi gaming builds, so I needed an adapter to be constantly plugged in and in use for gave saves. I've been through at least five brands on Amazon over the last 2 years because, without fail, they over heat and stop working quickly.This Kingston was my last hope. The good new is, this thing is really solid far for my use case of long retro gaming sessions. The bad news is, the extra reliability came at the cost of two other factors I was interested in: size and a keychain holder.While the Kingston is not the biggest adapter ever, it's certainly a jump up from the mini adapters I was attempting to use. This kind of pokes out the USB port of my Pi instead of blending in with a mini. I also wanted a keychain attachment to personalize a card for multiple users and just keep track of it easier in general. That's not possible here.To note another positive, the adapter doesn't have an annoying activity light on the front. Nearly every mini adapter I purchased looked like a light house in the dark.Overall, if things hold steady as is, the pros outweigh the cons. I would rather take an adapter the works long term than one that fits every single one of my needs. This is doing the trick!

very solid. protects card better than others. Plug and play. No effort required at all.
