FBA iSDA504ASV Aluminum MicroSD Adapter for MacBook Pro 15" Retina (Late 2013 - Mid 2015)

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.

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.

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.

4.5 Stars! What a BRILLIANT and easy way to add 2TB of storage to my MacBook Pro! Now, please note that the SD card reader in your mac is NOT super fast, but it’s fast enough. If memory serves me correctly, with a fast SanDisk card, I get close to 90-100MB per sec, which is fine for general file storage to keep my internal SSD free for the heavy-lifting. Only complaints are that once it’s in snugly, it’s hard to get out, and I have to use a small flat head screwdriver, as my fingernails just can’t do it. The other complaint goes hand in hand with this, but isn’t a problem of this unit, but more so the Mac, as sometimes the card doesn’t mount, and needs to be pulled out and put back in for the computer to see it. I know this is a Mac issue (at least with my machine, but likely others as well) because this happens with regular SD cards. So you’ll want to keep something handy to pry it open when you need to. I don’t have to do it often, which is good. I highly recommend this, and the only issue is the price of high capacity Micro SD cards. But still WAY cheaper than Apple’s tax on internal SSD storage!

Works as described. Like other reviewers, I found it impossible to remove this carrier without a screwdriver or similar device to pry it out. Fortunately, I carry a screwdriver with me everywhere or could use a pocket knife in a pinch. Otherwise fits well and definitely beats having to eject an SD card every time I put my laptop into my backpack.

Funciona y encaja perfectamente. No sobresale nada. No da ningún error al apagar el ordenador. Es una alternativa asequible de expansión de la capacidad del Mac. Únicamente hay que tener mucho cuidado de pedir exactamente el modelo adecuado para cada Mac (a veces parecen iguales pero cambian las dimensiones según el año de fabricación)

Juste parfait !! Rien a dire sur la livraison et l adaptateur revient moin chère qu un disque dur interne !! Et s adapte parfaitement , je ne connaissais pas j ai été agréablement surpris et de la même couleur que le MacBook a acheter les yeux fermer !!!

My understanding is that this adapter is a passive device, meaning that it has no storage capacity, no sleep mode, no speed restrictions, or any active circuitry - so all of the standard Amazon feature ratings are moot. I have a 400GB sandisk extreme micsoSD card in it, and it is great. No unmounting issues at all when my computer goes to sleep or gets shut off. The adapter is hard to remove (you need a screwdriver to pry it out) but that is the entire point of this device. Installing the microSD card into the adapter is fairly easy as it just slots in. The adapter is truly flush with no protruding parts whatsoever.

L'unico neo di questo adattatore è il suo costo un po' elevato. Dopo averlo testato posso dire che fa ottimamente il suo lavoro ed il suo costo secondo me trova giustificazione nelle seguenti caratteristiche: - La parte grigia che si vede in foto è realmente in alluminio e non in plastica grigia. Questo da un lato massimizza l'integrazione visiva con il materiale del MacBook Pro e dall'altro rende molto più robusta la linguetta su cui bisogna far forza per estrarlo dalla sua sede (fosse stato di plastica avrei temuto di romperla senza poter più estrarre l'adattatore) - Le dimensioni e la forma sono perfette, l'adattatore scompare perfettamente nello slot della SD e non è nemmeno difficile da estrarre facendo leva con l'unghia del pollice. Fate attenzione a scegliere il modello di adattatore specifico per il vostro computer. - Per quanto ho potuto verificare confrontandolo con gli altri a mia disposizione, questo adattatore non penalizza le prestazioni delle schede inserite. In conclusione, nonostante il prezzo promuovo questo adattatore a pieni voti e lo consiglio a chi è alla ricerca di questa soluzione. Tuttavia ricordo che, se il vostro Mac lo consente, esistono anche soluzioni relativamente economiche per sostituire l'SSD interno con uno più capiente e veloce (es. adattatori tipo il SupaGeek).
