BaseQi Low Profile Micro SD Adapter for Raspberry Pi

Works with MacBook Pro M4

I bought this so I could keep microSD cards in my laptop, as it only had an SD reader. Most of the SD card would stick out, so I needed a low profile adapter to be able to keep cards in without worrying about them breaking off in a bag or something. This adapter does the job. I'm using it in a Lenovo Flex 5 (Ryzen 4000) and the adapter sticks out about 2mm, which is actually good because it's just enough to get my fingernail into the grip to pull it out. The adapter is not spring-loaded, so if it fit flush it would never have come back out! As you can see in the picture, 2mm is not enough where I'm worried about it ever catching on something and breaking, nor is it ugly to look at, so I'm quite satisfied. I've had no issues running this for a couple of months now, in a Windows 10 x64 machine, using both a 64GB and 256GB card. Speed seems good, getting 90/60 on both, so nothing bad to report there either. Make sure the dimensions are right for your use case, and if they are, I recommend it!

Works great with my original Raspberry Pi. It keeps the SD card nice and flush. Works well on Android TV boxes and laptops as well.

I got this for my 2021 M1 Macbook Pro 14". First of all, the adapter did not work. I put a Samsung 128gb microSD card (that I know works when using the full-size Samsung adapter) into this BASEQI adapter and the Macbook failed to recognize it. Tried a couple of other microSD cards and they did not work either. Clearly, the one I got was defective. On fit, this BASEQI adapter is about half the size of a full-size SD card. It does sit perfectly flush inside the SD card slot of my MBP, but the fit was very tight. I had to apply some force to get it into the slot and later it was very difficult to remove from the slot. On my first attempt, I dug my nail into the SD card slot opening to grab the groove on the end of the adapter. With some effort the adapter came out. The second time, I could not get it out and cracked my nail. So then I used the small flat screwdriver head on my Swiss Army Knife Classic (the small one that fits on keychains). It came out pretty easy using that but this deformed the groove enough that I can tell that, with repeated use, the groove will wear out and you will wind having the adapter stuck inside your laptop. This adapter is probably a fifth of a millimeter too wide or thick than it ought to be. In any case, the adapter did not work, did not fit easily into the SD card slot of my laptop and is made from very cheap plastic. Returned.

I read some reviews on this product by people who used it in a MacBook Pro 13” before I bought it. This adapter is almost half the price of any of the small (Pi or 13” MBP) SD card adapters. Even though it's for the pi it works just fine in my 13 inch MBP. It fits very snug,and since I'm basically using it for extra storage that works out just great for me."Set it and forget it". The adapter is not completely flush but sticks out less than 1mm, which is also good because that makes it easier to remove if needed. Works as it should and much cheaper than the alternatives highly recommended.FYI (Base Qi’s adapter specifically for 13”, is metal and plastic, this one is all plastic but again,it costs much less.

It's great! It's thin and only sticks out 2 mm from my Lenovo Yoga 16" laptop (less than any USB stick, even the short ones), doesn't take up a USB port, and allowed me to add 1TB with a low profile - I keep inserted in all the time. The micro SD card I bought to put in it also has a faster write speed than the fastest USB stick, so it was worth the cost to me. :o) (The one star off was for the price - worth it, but $15 is more expensive than it shoud be in my opinion). If you want something that sticks out the least from your computer, get it!

Perfect flush fit for my Dell Vostro 5620. Make sure you put strong sticky tape on it as a tab to pull it out otherwise you'll need to use a pin to remove it.

In short, all of these micro-sd adapters do the exact same thing. It doesn't matter what computer it goes in. They can say it's for the Pi, MAC, Asus, or whatever, it's all about the size. BaseQi just loves to give their sizes in point inches. For this purpose, metric would be a more accurate measure. I actually purchased a digital caliper so I could easily convert and understand the actual sizes because I was shopping for something to fit my Lenovo Flex 11. The pictures are of the Flex 11 to give you an idea of fit. This Pi version wasn't exactly a good fit but it was better than having anything stick out to catch on something. For the price, it was a better decision. The fancy aluminum ones were just too pricey. The pictures are of a standard adapter, a cheapy short one that kind of works but still stuck out too far, and this Pi version. If you are intending to put in a SD card and leave it in semi-permanently (like I am), then that's one thing but if you want to easily remove it, the tab really helps. What you see is nothing more than a square cut from a post-it note. Works great. If you look closely, I already have scuffed up this adapter by wedging something in to pry it out. For the record, BaseQi FBA_iSDA504ASV probably would have been the perfect fit for the Flex 11. But at $25, I'll stick with what I have.
