    • Fits the SD slot perfectly on my MacBook Pro (M1)
Size: Adapter without HDMI Dust Plug Color: Space Gray
The microSD adapter perfectly fits into my MacBook Pro and holds a 512 GB card. It works very well and is easier to extract from the slot than the previously used "designed for" MacBook Pro SD card. I'm very happy with this, especially since the "designed for" card in a 512 GB size is 3 times as expensive as this adapter with an Amazon microSD card of the same capactiy. ... show more

    • Doesn't stick out of the laptop at all.
Size: Adapter without HDMI Dust Plug Color: Silver
This adapter is great. It allowed me to put a SD card in my computer and tuck it away to where it doesn't even stick out of my laptop whatsoever.

    • Better than the old UHS-I version.

Works great. Thank goodness BaseQi was able to finally release this. Their original UHS-I adapter was great. I paired mine with a Lexar 1000x 256GB V60, U3, Class10 microSD card. Did a stress test and transferred ~150GB test file. Card and enclosure never overheated. ~90-110MB/s continuous write from iStat Menus process. No idea how accurate it is. It sits very flush with the body of a 14" M1. To efficiently remove the card, a longer nail (ouch) or a small prying edge tool might make it easier. Totally worth it to add some additional storage without stressing the internal SSD. Hasn't had any issues booting up and shutting down with the Mac. I leave it plugged in all the time. I just use a USB-C dongle with a bunch of ports and readers to make up for the loss of an UHS-II SD card slot. Keep in mind this product is just an adapter. It is a pin-to-pin adapter. There is NO IC chip, there is nothing that will limit or increase your speeds. All your speeds with this adapter are based on the microSD card you put inside. If you put a UHS-I microSD card in this, you will get UHS-I SD card speeds. If you want to see better speeds, you need to open your wallet for a quality UHS-II microSD card. ... show more

    • BaseQi as a fixed 1TB drive for Mac book Pro
Size: Adapter without HDMI Dust Plug Color: Space Gray
GREAT ITEM!!!! Fits great in my MacBook Pro M1 Pro, works fast with a 1TB SunDisk. Very fast with images and text and any other file. I don't do video editing so the performance is excellent. Strongly recommend!

    • Tener mas capacidad en forma sencilla
Size: Adapter without HDMI Dust Plug Color: Silver
Tengo una tarjeta de 2 TB colocada en mi MacBook Pro mediante un adaptador que queda prácticamente al ras del equipo. De esta manera, además de los 512 GB internos del disco principal, dispongo de 2 TB adicionales integrados físicamente dentro de la notebook. Este sistema viene a resolver una limitación habitual en muchas Mac: no permiten ampliar el almacenamiento interno ni reemplazar el disco como en otras notebooks. Algunos modelos de otras marcas ya incorporan una ranura microSD pensada justamente para ampliar capacidad de forma discreta y segura, sin depender de discos externos colgando por USB. En mi caso, la microSD cumple esa función: • Amplía el almacenamiento total sin modificar el hardware interno. • Permite mantener todo integrado, sin cables ni dispositivos externos. • Reduce el riesgo de golpes o desconexiones accidentales. En definitiva, es una solución práctica y prolija para ganar capacidad de almacenamiento sin intervenir el equipo ni cargar con discos externos. ... show more

    • This is the flushest storage solution for your MacBook pro
Size: Adapter without HDMI Dust Plug Color: Space Gray
Considering how expensive Apple's internal storage is, i've looked for solutions like this since my late 2013 Macbook pro 15 retina. PROS: -It sits absolutely flush with the Macbook pro when inserted unlike the Transcend JetDrive that sits ALMOST flush -You can upgrade the Micro SD card instead of having to upgrade the whole thing, like Transcend JetDrive. -If you keep the SD card at ≤512 GB, you can take advantage of UHS-II speed Cons: -The microSD cards can be almost too tight in the BaseQ Overall a great and versatile product to increase your internal storage. ... show more

    • Stealth mode external drive!
Size: Adapter without HDMI Dust Plug Color: Silver
Updating review - this adapter has jammed into my macbook pro sd slot and the front part has now broken off - it is completely jammed and I need to send in the laptop to Apple to get it removed. I cannot recommend this, buyer beware! Completely stealthy way to add external storage to your MBP. This fits completely into the SD slot and you cannot tell its there, completely invisible. No more usb thumb drive dongle falling off. THIS DOES NOT HAVE ANYTHING TO DO WITH THE MICROSD CARD'S READ/WRITE SPEED! I checked and got identical results for this and for the adapter that came with my microsd card. If you think its slow, get a faster microsd card. HINT: spend a little money and get a fast microsd card. It is a tight fit to get the microsd card into the adapter - be patient and it will fit in. Adapter is also a bit tight to get out of the SD slot but I had no problem using my fingernail. Excellent product. ... show more

    • Functional but rough
Size: Adapter without HDMI Dust Plug Color: Silver
It works. I wanted to have additional storage space on my Macbook Pro without having to constantly remove something, so this can permanently stay in there unless I have to take it out for some reason. A problem I had was how tight the fit was to get the Micro SD in it. I really had to force it in and was afraid I'd break it or a piece of the metal bands would bend in the process or something, but eventually it got in there all the way. Then getting it into the laptop I was kind of expecting like a click or smooth entrance, but you just shove it in and my Macbook recognized it immediately. So wasn't exactly a seamless experience with the product but I can argue with the end result ... show more
