Review: Perfect depth and works great in Acer Chromebook 15 - I have an Acer Chromebook 15 CB5-571-C09S and just received this adapter. It works VERY nicely in my Chromebook. I verified before opening the package that this adapter was the right size and the right pin layout (it is perfect in both respects). I suspected and now have confirmed for myself the reason the adapter may not sit evenly in the slot as reported by another reviewer here. The slot in the Acer Chromebook is not EXACTLY the same shape at each end as this adapter is at the ends of the aluminum end cap, not quite as rounded. The result is that the adapter "wings" don't fit all the way in easily. You can do one of 2 things to fix: either trim the ends of the slot opening to be more rounded or fitted to the adapter, or gently file the aluminum "wings" just a little to fit the slot (what I did). Then it will fit perfectly. I know this will void any warranty on the item but I verified it is working before doing anything and test fitted many many times to ensure not to remove too much. There are still "wings" sticking out on each end of the adapter, just not quite as much as original. This adapter now fits perfectly even and flush in my Chromebook slot. OK, maybe not perfectly since there is a curve to the underside of the Acer that doesn't match the adapter perfectly but I really have to try to even feel it when I run my finger along the side of the Chromebook. I use a SanDisk Ultra 128GB micro SDXC card in the adapter and can now just leave it in there all the time. The finger nail slot works as advertised to remove it if that should ever need to be done.
Review: Works great with a little help. - First off, I tried several other types of MicroSD card adapters but none gave me much confidence either by way of build quality, performance or both. I spent the extra money on this adapter because I was at my wits end with the other four or five I had tried. As far as this adapter goes, the build quality is great, it fits perfectly, looks like it belongs where it is and is easy to remove when necessary. I am using a SanDisk 200GB MicroSD card and have had no performance issues. I use the drive to hold my iTunes library (north of 100GB) and some other media files and haven't had any troubles with the adapter. I have experienced slow downs with data transfer rates (attributed to the MicroSD card itself) but I benchmarked my MicroSD card with a USB adapter and a couple other SD card adapters including the BaseQi adapter and saw no performance impact using the BaseQi adapter versus the others. One thing I did notice that I determined to be attributed to Mac OS X and not the adapter is that the drive mould rarely remount after my computer woke up from any length of being asleep. After a bit of Google-Fu and testing other standard SD card adapters, I came to the conclusion that Mac OS X (I'm on 10.11.5 right now) is fickle about remounting SD cards after awaking from a sleep period regardless if you use the Power Nap feature or not. My solution that has worked out exceptionally well is to use an application called Jettison to remount the SD card after awaking from sleep.

## Questions & Answers

**Q: What are the read /write speeds like? Is it limited to whatever the micro sd card will do?**
A: I have the same read/write speeds with this adapter as I do with the one I got from the factory. Heck, this one actually had a slightly faster read speed. However, when I first used it it was slow, even after formatting to mac journaled. Then I switched to the adapter that came with the card, and it was super fast. After switching back to this adapter, the card became super fast again. It’s weird but whatever it worked!

**Q: I know this is designed for a mac but will it dork in a dell xps 15 9550**
A: Hi, Our model 750A is made for Dell XPS 15", so pls click on below link to place your order, tks.https://www.amazon.com/dp/B01LX8GMZF

### ⭐⭐⭐⭐⭐ Needed this 10 years ago!
*by C***E on January 27, 2025*

I bought this for my 15 inch 2015 MPB I picked up from Ebay with no internal drive. I Installed a 128 GB drive from a previous upgrade from another Mac but needed something quick until I purchased another drive. I had several micro sd cards that I never use and decided to get this adapter. Put a 128 GB micro in this adapter and formatted it to apfs. So far it works great and it hasn't unmounted itself at all. It also fits my 14 inch 2021 Macbook Pro but sticks out just a little. It fits flush in my 2015 MBP.
