this is one of the best for Mac HDD upgrade since Apple is the only one so far selling TRIM supported SSDs which are very expensive, now it is so good to know that AngelBird is the first to launch TRIM supported SSDs (not software tweaked ones which are now having difficulty since upgraded to OS X 10.10), worth the bucks :)
Edit: Costs $27.63 shipping fee for the 512GB version I purchased to upgrade the iMac Retina
I saw some videos about DIY RAM upgrade and it looked straightforward, but hard drive upgrade might be trickier to do, is this right??
with other thrid parties' SSDs, yes, but now these are out-of-box TRIM supported :)
sorry, not sure what this means (not very techie)… but I'd still have to teardown the iMac I suppose?
Yeah! The screen used to be held on by magnets and you'd need suction cups, the current model uses adhesive strips that you need a special tool to cut & you then need replacements strips to stick it back on again(https://www.ifixit.com/Teardown/iMac+Intel+27-Inch+EMC+2639+…). It's not for the faint of heart, even OWC the company that made a business selling these types of upgrades no longer does them for the iMac!
@jonbob: That looks scary… and beyond what I'm capable of haha, guess I'll just upgrade the hard drive via Apple, sigh… thanks for the info :)
you mean Austrian company?
"Angelbird Technologies GmbH is a hi-tech company based in Vorarlberg, which although the smallest province of Austria"
sorry, my bad, edited :)
based in Vorarlberg
isnt that the guy from Harry Potter
The apple tax is strong in this one…
Hasn't trim been supported on a lot of other SSD's (particularly Sandforce controller ones) for years?
the sammy 850pro seems to have it - http://www.samsung.com/global/business/semiconductor/minisit…
OP has pointed out (but probably didn't make it clear enough) that these SSD's support native TRIM in OS X, i.e. without software like TRIM Enabler.
thanks :)
not in a mac though…..
apple playing silly buggers ;)
not with this ine because the trick they use is not based on software which Apple cannot control it, so, if you are after a cheaper option for SSD upgrade for your Mac computer, so far the best choice
Apple being Apple only supports TRIM on Apple-supplied drives (by matching the model name reported by the drive) What this drive does is report itself as an Apple drive rather than an AngelBird Whatever.
In the past most people have used programs that hex edit the AHCI SATA kext to make TRIM work with any drive. The problem is that in Yosemite, new security features require all kexts to have valid signatures, and this completely breaks it. The only solution is to disable the kext signing security feature globally (and new versions of TRIM Enabler will apparently do this for you.)
I would argue you're still better off with a brand/drive with known-good reliability — the 850 Pro you mention is actually quite resilient against performance degradation on non-TRIM systems — AND disabling the kext signing behaviour isn't THAT huge a deal (presuming you were fine with it from 10.0 through 10.9…)
But if you absolutely must have TRIM and can't possibly disable kext signing, it looks like a good option.
Of course…that's assuming its cunning ruse continuez to work. It will be interesting to see if Apple work out how to identify if it's non-Apple and disable it some other way — such as, say, the fact it's SATA when Apple's are PCIe these days…
Ah thanks for clearing that up, surely with some of the iaktos builds, you can install unsigned kexts?
With any version of OS X, legit or distro, you can install unsigned kexts. Just have to enable that mode.
worth the spending if you purchased a discounted iMac Retina from DickSmith and want to upgrade with SSD for better performance :)
