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

I've looked at a lot of MicroSD card readers in the past, but this one is by far my favorite. The design is genius - the fact that the MicroSD card fits completely inside the reader, with no part of it protruding, is a game-changer. It's so much more convenient and secure than other readers I've used, where the card would protrude from the end and be vulnerable to getting damaged or lost. I don't have to worry about the MicroSD card getting bent or broken. The reader itself is also very compact and lightweight, making it easy to take with me on the go. It is also a great value for the price. The reader works flawlessly, and transferring files to and from my MicroSD card through the USB-A port is quick and easy. I've had no issues with compatibility or performance with Windows, MacOS, or Linux. Overall, I'm extremely happy with this MicroSD card reader, and I would highly recommend it to anyone who uses MicroSD cards regularly, but most especially if you want the ability to keep a MicroSD card safe in the reader for a while (like while transporting it back and forth).

This thing is honestly one of the smallest MSD card readers I found that'll read any of my cards (tested and used with up to 512gb MSD cards) should be compatible with up to 2tb MSD cards. However it's not compatible with MSD express cards that I am aware of

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) 32GB All 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.

Sadly, one of the prior reviewers has system issues causing the speed problem they where experiencing. How do I know this you ask? Well, I have and have access to hundreds of systems, and have over a hundred MicroSD cards. Ok, the big kicker was the fact that my HP Laptop, and a Dell desktop have USB 3.0 ports that run at USB 2.0 speeds, seriously such a PITA, why color it blue and/or dont mention it in the Specs... so dumb! (No other USB 3.0 drive I plug into these ports will run over the 35MBps 2.0 spec speed, so frustrating, tried 13 different device's, and yes, there are ZERO usb 2.0 IC's on either system board and none in device manager, 3.0 only) I have read that there are auto negotiation issues with some usb 3.0 chipsets so that might be the problem, needless to say, not the sole fault of this reader/adapter. Now, onto the actual reader! I do worry about how tight of a fit the internal structure is, if its too tight, it can scratch/scrape away the MicroSD top, thankfully, that did not happen, and with the one UHS-II card, it works like a charm and hit about 220MBps. Pretty nuts, and so far, has not had ANY issues. Outside of that, its $10 for top tier reader! My only issues, are the same issue I have with almost all readers of this size, no listed orientation to insert the card, yes it should be obvious and to me it was, but its not to all and a co-worker almost inserted it upside down... AND the heat, and keep in mind, heat is a natural byproduct of something this small being powered, its a thing, get over it! BUT, I wish they would thermal pad the top/bottom of the internal card to the plastic casing to dissipate the heat, or put some venting on it, just something to help, because when I wrote a large collection of ISO's to the USH-II card, I wanted to put it under a pan and make some eggs...

Much better than SanDisk MobileMate. They started to slip efter a few uses. No problems with this one.

Tested micro SD card Samsung Pro Plus with this reader, and with an older reader. With this one the speed was closed to advertised, the old reader (which is USB 3.1) shows significantly lower speed.

First of all, Kingston makes two variants of these, one for Micro SD cards and one for SD cards, so make sure you purchase the correct one. This is a review of the Micro SD card version. Anyways, I use UHS I cards with my camera and was always frustrated with my other SD card readers because the read speeds (the speeds at which I could transfer files from the SD card to my computer) were always around 95MB/s max. This is even though the advertised speeds on the cards themselves are about160 MB/s and above. Well, the card manufacturers are not lying. With this Kingston card reader I am reaching close to advertised speeds (within about 10 MB/s, since it often fluctuates). Very happy with the results so far. Also be careful when you purchase SD card readers advertised as "high speed", because on Amazon anything with USB 3.0 connectivity is often called "high speed". However, if the SD card reader itself is not high speed, than it does not matter if your connecting it to your computer through USB 3.0. A few cons: this is made out of hard plastic so it's durable but I think it could still break if stepped on. It is extremely small so easy to lose (or step on). I have mine attached to a USB-C dongle, which gives it some more bulk. Also, I wish this had both SD and Micro SD card compatibility on the same device. .

Karty microSD osiągają na tym czytniku maksimum swoich parametrów. Polecam!

I hoped that it would match the speed of another SD card reader I have. Unfortunately, it tops out around 90 MB/s with all the cards I have. Design-wise, looks good/sturdy/compact/convenient.
