Transcend1TB JDL330, Expansion Card for MacBook M4 Pro 2024, 2023, 2021, Lightweight Design, Up to 95 MB/s, JetDrive Lite 330 - TS1TJDL330

I purchased this JetDrive for automatically backing up my MacBook Pro with Time Machine on a daily basis. I have not been as diligent as I should in hooking up to an external drive and backing up which has burned me in the past. The fit of this Transcent JetDrive in my Mac is incredible as it fits snuggly to the SD port and non-intrusive at all. In my opinion the drive is meant to be stored in the SD slot and not removed over and over again as it is difficult (with your fingernails) to get out of the slot. Perfect for my intended use as a back up solution. I formatted using disk utility with APFS encrypted so it requires a password in case my computer was lost or stolen. I used time machine for back up and the initial copy took almost 6 hours (about 350 gigs of storage) so you should perform the initial back up just prior to going to bed. Subsequent backups only take about 2-3 minutes each time. I set up my time machine backups to automatically perform once a day so when I turn on my computer in the morning it updates automatically in the background. For weekly backups (in case my MacBook gets lost/stolen) I purchased the Samsung T7 Portable SSD, 2TB External Solid State Drive and partitioned in 2 partitions… 1 for weekly time machine backups and the other for Carbon Copy Clone backups which provides a perfect clone of your internal hard drive in case time machine has a hickup. The Samsung T7 is incredibly fast, small, and when finished backing up I lock it away in the safe. In summary the Transcend JetDrive is the perfect solution for daily time machine backups and as you can see in the photo an SD card you can plug into your MacBook slot and forget about it as it sits flush and automatically performs the time machine backups in the background.

Works great, I’ve even installed apps and games to it that all run just fine from the card. Way cheaper than paying for the extra storage from Apple at purchase.

Yes this fits and works in a 14" M4 Macbook Pro. I won't use it for Time Machine (as I think that is where a lot of the read/write errors occur), but it is great to have another Terabyte of storage.

The fact that this SD card is flush with the side of Macbook Pros means that this SHOULD be in theory a great sd card to set it and forget it and use it with Time Machine and auto backups. I bought it for this reason back in August of 2022 when I purchased a 16 inch Macbook Pro M1 system and it was working just fine for this for about nine months until it just died for no reason. The disk would not mount no matter what I tried and even trying to erase/format it did not work.Thankfully it died when I did not need it for a backup, but wow is this thing absolute garbage. Amazon was nice enough to give me a free replacement and, while it is currently working and backing up into Time Machine as we speak, there is no way I will make this the only backup drive for my Mac.As someone else said in another review, the problem with these are they use ancient SD card chips from the early 2010s. When the Retina Macbook Pros came out in 2012, the SD slot used was much different than the technology in the current M1/M2 macs. It isn't so much the speed of the card, but the total lifetime write/rewrites on these seem to be comically low and this early 2010's tech just does not work for how M1 and M2 macs write to the drives. These cards WILL die on you. The technology is old and only relevant now because the Macbooks prior to M1 did not have SD card slots. All Transcend did was put a "Compatible with M1 macs" sticker on decade old technology due to the SD slot returning to the M1 macs.STRONG RECOMMENDATION TO AVOID, just buy a real SanDisk card to use for backups. I will update this if and when the replacement dies.

I have a M3 16-in Max MacBook Pro. This wasn't technically made for this specific macbook Pro but it works perfectly flush all the same. I almost returned it because I forgot I had a 400 GB mic SD card and another adapter that also flush mounted but that card was much slower than this one so for the price and a nice flush mount I use it for my time machine backup of my documents and downloads folders. It won't back up my whole 1 TB hard drive but I don't need everything backed up anyway mainly just documents in a few other folders and it does it very fast due to the speed of the card and memory chip. Actually there is no card it's all soldered so the speed of the chip is great and the flush mount you can never go wrong with. Fits flush but all you need is a good thumbnail or toothpick or something to get the card out with ease if you ever need to for whatever reason. You can't stuff it in so far that it'll get stuck or anything just don't force it in. Slide it in slowly yet slightly firm until it's flush and then leave it alone and it'll mount right up on your desktop after it's been formatted properly with disc utility
