Transcend1TB JDL330 JetDrive Lite 330 Expansion Card for MacBook Pro 2021 up to 95/75 MB/s TS1TJDL330

Bought this for my rMBP Early 2015 as I wanted to save a bit of cash, so I went with the 128GB model thinking this would save me about £120. Does exactly that, instead of spending obscene amounts extra via Apple for little difference I got this and have been extremely happy.No installations, Mac picks it up straight away as an external drive that you can save things to (although I've not yet attempted to save any applications nor do I know if you can- potentially if you install it first on the built in hard drive, copy it to the JetDrive and then create a shortcut for it on the dock?) and does not seem to have any issues when going to sleep/waking up. I did encounter the Storage Card 'not being ejected properly' once when I had closed the lid on my laptop that resulted in the card not being recognised however that hasn't been repeated since. All I did was pull the card out and push it back in again to get the laptop to recognise it again.Read and write speeds have been very good, not as fast as my USB 3.0 storage cards or hard drives but when there are no cables lying around and getting in my way and the save is happening on the laptop itself I was not in any way bothered about it taking the slightest bit longer. To get the best speeds out of this device I did have to reformat the card to the Mac Journaled partition as many reviewers have already suggested you do when you first get this. Simple process through Disk Utility and Google!In terms of form factor, it fits flush to the rMBP with only the smallest of protrusions. To be entirely honest, without this tiny protrusion you simply would not be able to pull the card out at all, which as I've mentioned above can be a helpful fix.All in all, does what it says on the tin, and has been extremely helpful for that little bump in memory. I would highly recommend!

This card is slow but I do not need it for speed. I love how once in you can forget it's there as it's flush to the side of your Mac. A great way of extending your storage . Strange how not more of these are made by other companies.

Had a Nifty minidrive before, but they have had so many problems with the 2012/2013 15" Macbook Pro Retinas. Just wasn't reliable and kept unmounting itself and tried various things like bits of tape etc to get it to stay in place, with no joy. Nifty no longer sell for the 15" retina so must be having issues with the design.Saw this and liked the fact it states the Transcend JetDrive Lite 350 model is for the 2012 and 2013 15" Retina Macbooks. Slide in to the SD card nicely and mounted straight away. It's nearly flush in my Mid 2012 Retina. Sticks out about 2mm's.The nifty has a nice little cut away and removal key for easy removal from the slot. This doesn't have anything like that. Wondering if it's a patent issue with Nifty as it really should and removing this thing isn't going to be fun without some decent nails or tweezers to get a grip. So hence 4 stars over 5.*Update* Dropped to 3 stars as found speed of access having moved my iTunes media library to this card made the whole iTunes program run extremely slowly and unresponsively. Moved library back to the built in SSD and will have to re-think what to use this extra 128GB of storage for now...**Update 2** Increased back to 4 stars as after formatting to Mac OS Extended (Journaled) the performance greatly increased and it's very usable. So much so I have now upgraded to the 256GB Version. Great drive. Only slight gripe is it's awkward to remove if you have short fingernails like me.

This is not my first of these - I previously owned the 128Gb model, but after realising that it was just too small, I upgraded to the 256Gb model, which is (obviously) twice the size.Speed on my 2015 13" macbook pro is very good considering it's essentially a cut down sd card. Blackmagic speed test rates it around 35MB/s write and an impressive 90MB/s read (see screenshot). Clearly not in SSD territory, but good enough to work well as a storage drive. I store most of my Steam library on it and games load quickly and take up no space on my internal drive.I used the software that comes with it initially to unmount the drive when sleeping and re-mount when waking, but I was having issues with battery drain, so I switched to using Jettison, which seems to drain the battery less. I do still experience a certain amount of battery drain (quite variable), but it's possible this is not due to the drive.A much much cheaper option that a) upgrading the SSD or b) buying a new macbook! Also much handier than an external ssd (been there too) - mine had a habit of getting knocked and dismounting.Only slight annoyance is that obviously you lose the sd card slot - easily remedied by buying an external USB3 card reader for a few pounds.

Used in my M2 MacBook Pro, good form factor for additional (slow) storage. Unfortunately, failed after 18 months so quite a big waste of money.Edit: I managed to get the disk to work again using the mac's hard disk tools. so; lost all my content but the disk is mountable and useable again. Not sure how trustworthy it is so wouldn't recommend.

It’s surprisingly important that an item you use all the time looks as good as you can get. Specially an Apple product, the company associated with good simple modern design.So this is an SD card that fits in the MacBook Pro slot and doesn’t stick out. That’s it. Nothing else. It works, it’s flush and it’s in my MacBook.

this is the best way to expand storage in your macbookif you use a normal sized SD card it's gonna stick out by about an inch. It sucks.get one of these instead
