More built-in storage for your Mac - the easy way!
on 4 April 2015
As far as the product is concerned, it's excellent and it's quite quick (at least read speeds). Expect write speeds to be just into the double-digits of MBs per second but In everyday use, you won't notice any speed issues whatsoever. If you're buying one of these, you are probably doing so to basically turn your SD-card-slot into a solid-state expansion bay, hence using it to install your programs, etc. on it. It essentially turned my 256 GB of Macbook Pro storage to a total 384GB - just enough to allow me use my Macbook Pro as my desktop-replacement. Physically, it sits flush, thanks to Transcend multitude of models of the same card with tailored dimensions (make sure you order the correct one for your model and model year).
If you're purchasing this product, I will assume you are trying to do the same - maximizing your built-in laptop storage for as little outlay as possible.
You need to be aware of some limitations. Initially the JetDrive card is formatted as MS-DOS/FAT so copying, etc. is very slow. So the first thing that needs to be done is to format the card as Mac Journalled via Disk Utility - allowing it to reach it's full speed potential.
Also, the JetDrive card will need to be inserted perfectly into the Mac's SD slot. Even the *slightest* of smallest gaps will plague you with constant Mac "Disk Not Ejected Properly" messages every once in a while, even though you didn't do anything to jar it. Pushing it in with your thumb won't fix the error from reoccurring either. Removing the card completely (which is a test of patience and nails as it's hard to remove - use a lot of gentle rocking) and reinserting it properly is the only way to get rid of these messages for good. For this reason, I recommend you *never* remove the card once you have it inserted well. If you need to access another SD card from time-to-time - buy a cheapo USB card reader - maybe one that doubles as a keychain fob.
Bear in mind that the Mac sees the JetDrive simply as an inserted SD card, which means it will not be seen as a *drive*. Had it been seen as a drive, it would have been possible to RAID array it with your existing drive (using Disk Utility) to turn into one large lump of storage. That's not a fault with the JetDirect, just an OS-limitation. Still this doesn't negate the use or the need of this JetDrive card by any means.
As a lot of Mac software *insist* on installing on to the boot disc or disc in general, this won't allow most programs to be *natively* installed on the SD card. However, there are ways around this. You can install the software on your boot drive (as usual) and then move it's application and/or data manually to the JetDrive. Once moved to the JetDrive, then create an *alias* (right click and select 'create alias') and place that alias where the data/application was on the boot drive. This way, you free space on your precious boot drive for other junk and it launches as expected.
Another useful tip is that iLife applications (such as iTunes, iPhoto, etc. and other programs that use data like Photoshop, etc.) allow you to specify where the data is kept, thus enabling you to make use of your JetDrive. Using this method, I was able to move my entire music and photo library to the JetDrive as well.
Also, if you use Parallels or other Windows-virtualization software, you can set or move the virtual disk image onto the JetDrive instead allowing for more of your primary storage to be freed.
In short, I wholeheartly recommend the JetDrive. It's faster and cheaper than it's microSD competitors (when comparing to the 128GB capacity) and does exactly what is needed - free up your storage. Especially if your Mac is a Macbook Air or Macbook Pro Retina where your cost-effective upgrade options are budget-limited.
