Yippee!!! - Very recently, my mom bought me a Surface Book with 128 GB of storage for my first year of college. I figured that it would be cheaper to get the 128 GB version and just increase the storage via an SD card. Upon inserting an SD card for the first time last week, I was kind of disappointed to discover that half of it hung out of the slot. Not exactly what I'd call useful (for my needs anyway). After some digging, I found the BASEQI. I was hopeful it would be as nice as everyone on here says that it is, and it definitely is! It is machined beautifully, and fits my Surface Book perfectly. It is completely flush with the body of the laptop, and is pretty easy to remove too. The color doesn't quite match 100%, but seriously... who cares?! It looks great and works great too. Thank you so much! A little pricey, but totally worth it. It's top quality, for sure... and even after purchasing this along with an SD card, it's still a heck of a lot cheaper than buying a Surface Book with a higher capacity drive. And not having to deal with a protruding SD card is obviously a huge plus too.

Just to let you know, I am going to shop around for a similar device that does that first before buying this. It is important to me to be able to take advantage of the faster speeds of UHS-II or UHS-2. Thanks for considering it - although it appears you have been considering it since 2016 and it is now 2019 so that doesn't look good. **Q: Does this adapter support uhs-i?** A: If you put a uhs 2 card into this adapter, will it work? I know it doesn't have the extra pins, but will it work? **Q: The 350a appears to be short ~0.5mm short for the microsoft surface book 2, any plans to support this product?** A: I emailed the company and they replied that they are working on a Surface Book 2 version, but did not give any details on when it would be released. **Q: Does anyone know if this adapter fits flush with the new Surface Book 2 model (i.e. does it "stick out" at all?)** A: For surface book & surface book 2 13.5" - please choose model 350A. For surface book 2 15" - please choose model 351A. Thanks. ## Customer Reviews ### ⭐⭐⭐⭐⭐ No more protruding SD card! Yippee!!! *by C***L on July 13, 2016* Very recently, my mom bought me a Surface Book with 128 GB of storage for my first year of college.

It fits securely, looks clean, and is great for keeping extra storage installed without affecting portability. I use it with a 1.5TB micro SD card and have no issues. ### ⭐⭐⭐⭐⭐ Very handy, cost-effective solution for expanding SB2 storage; doesn't protrude at all - Great! *by C***R on April 13, 2022* So I can vouch that this little adapter is quite functional and effective as a purchase still in 2022. Rather than buying the latest iPad, I realized that for my needs the older Surface Book 2 was a better fit for my primary uses. So with a simple, high quality 512MB mini SD card (separate purchase) and this adapter, was able to quickly expand the memory of my rig. (The card I purchased was already formatted, but I re-formatted it so that the card would not be recognized as removable storage but viewed as an internal drive (like a partition / folder but treated as single unit, as some software doesn't play well with saving to removable storage). From comments when I was researching the product, it seems that some customers may have inserted it the wrong way and forced it, in some cases causing damage. Just take a moment to ensure you have it aligned the right way and insert it gently, doesn't need to be forced. It sits flush and blends in quite well from a design / aesthetic perspective. Very pleased with this purchase and highly recommend it. On a related note, I also purchased the Skinomi full body protector (film), also available here on Amazon, as bit of sleek and effective protection. Also highly recommended. ## Frequently Bought Together - BASEQI Aluminum MicroSD Adapter for Microsoft Surface Book 13.5" (Model-350A) - Add up to 1TB of extra storage space - SanDisk 512GB Extreme microSDXC UHS-I Memory Card with Adapter - Up to 190MB/s, C10, U3, V30, 4K, 5K, A2, Micro SD Card - SDSQXAV-512G-GN6MA --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.at/products/24435642-baseqi-aluminum-microsd-adapter-for-microsoft-surface-book-13-5](https://www.desertcart.at/products/24435642-baseqi-aluminum-microsd-adapter-for-microsoft-surface-book-13-5) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-08-29*
