I haven’t switch to Yosemite yet. but unless i'm missing something, I think native trimming unused blocks once in a while should keep SSD in a good shape. at least (for now) this 'd avoid hacks that disable Kext signing .

fyi, to trim unused blocks (enter single user mode) restart - hold down [cmd] + - type [fsck -ffy] (notice space before -) when done type exit to reboot.

Edit: make sure trim is active at the time you run fsck (you may deactivate trim afterwords)


It should be running all the time. Not treated as a maintenance task.

I mean, (if trim is inactive and at some point the SSD start to slowed down) if i enable “TrimEnabler” … run fsck command (trim unused blocks) … then disable “TrimEnabler” … wouldn’t that bring the SSD speed back?

So why did they make previous iMac's partially upgradeable and Mac Pro's fully upgradeable? It's like their UI. There were guidelines, now it's thrown out the window.

What "guidelines" for the UI were thrown out the window?

----------

Then, it's also "capitalism" for us, customers, not to give Apple any money by just switching to OSx86 and Hackintohses. Which we wouldn't do if Apple didn't try to screw us up by, among other things, not allowing for TRIMing third-party SSD's.

Haha, You apparently think I'm on Apple's side. I'm just stating the facts. You don't have to like them.

You can make Hackintoshes, buy a Surface 3 and sing Kumbaya with Larry Page.

The point is no one is going to support their competition. This isn't rocket science, it's called Capitalism, and thus far they've made the right choices or they wouldn't be so successful... *womp* *womp*
 
Skeuomorphism.

HaHa, Um... It's called a design change. OMG OMG OMG the sky is falling!

You going to get angry at Mercedes for changing their headlight designs?

Apple dropped Skeuomorphism. Microsoft has done it - Were you crying when Windows 7 didn't look like Windows 3.1 or Windows 95? :)

Google has done it.

Ubuntu changed their UI...

Please start burning them in effigy as well for a... *gasp* design change... I can't believe Ford stopped using steel bumpers! THE NERVE OF THEM!!


:p
 
The suggestion above (install an older OS X version on another partition and frequently boot in there to explicitly trim) seems to be workable.

thinking about doing this, although it does waste space. once trim is enabled, does the os automatically trim the ssd once i log in to the trim enabled partition?

Well, they may do whatever they want to do. It's just that exactly the same, overly restrictive and customer-alienating moves lead to their near-bankruptcy in the 90's.

Some companies never learn from their own history...
 
I installed a crucial MX100 512GB in a mac mini and it only took a press of a button with trim enabler to enable trim, what's the big deal with pressing a button, especially when it saves you $90 over the anglebird.. The mx is faster than my 2013rmbp.

Because "pressing that button" under Yosemite involves disabling kext signing, which you can do (security risk, however) and if you reset PRAM or install an update and it gets re-enabled, you might leave yourself with an unbootable system volume.

Yes it would.

I hear you but I like less skeuomorphism. Skeuomorphism wasn't written in stone. I think there is something to be said about UI evolving. TRIM is annoying but they may decide to change their minds as we're moving away from any mobile devices using traditional platter HDDs.
 
While this is cool, I'd be much more excited about third parties starting to support apple's blade SSD form factors.
 
Buy OEM Apple SSDs off ebay. I bought a 512GB Samsung (830-based) Apples OEM SSD for my 2011 iMac, and have had no issues.

Some sellers also have the OEM PCI-stick based SSDs as well.

Same here. I picked up the same drive, TRIM supported and it's fast.
 
can you explain how to go about using Disk Utility for trimming? thank you in advance.
not sure what "Menneisyys2" explain 'd be? but from what i know,

To trim via Disk Utility – (make sure trim is active) - select your SSD > "Erase" > "Erase Free Space" (you may need to run some terminal commands afterwards to speed up boot time). However, this is a time consuming process.
btw, you can also temporarily enable trimming instead of running older OS.

(instead of using Disk Utility) I usually run fsck command to (natively) trim unused blocks after OS updates (or after secure empty trash), it’s easy & it takes only few minutes.


Edit: u could also, use Disk Utility >"Repair Disk" (exclude boot from the recovery partition) – I found this option here

Thanks.

(as maintenance/workaround) i think that’s probably what i'll do for now. (after switching to Yosemite) keep trim inactive and maybe once a month run fsck to (natively) trim SSD. This way no kext/security issues & no surprises (especially with future updates) :D

Same like others, still interested to find out what trim mechanism Angelbird implement in their SSDs? if any?

There's a link in this thread, pointing to a French site showing that the SSD declares itself to be an Apple-SSD.

All this hassle in the name of "security", pffhaha. :cool:

The commad is fsck -ffy

You use it, or at least I have in single user mode.

I don't think you can use it in the terminal becasue you'll be trying to run it on a mounted drive and that's bad juju.

For posterity in Linux is fstrim -v then whatever drive label

...

I noticed that "fsck -ffy" does not do the trim process, unless you _already_ have trim enabled - which must mean that you have to enable trim before that will work (and kind-of negates that as a special tip with Yosemite, eh? )
And, I don't think you need the extra -f, so it would just be fsck -fy, again, in single user. Don't forget to enable trim, go to single user, run the command, then reboot, and fina-a-a-a-lly, disable trim again.
I'm just hoping that someone will figure out how to get trim on, so you can leave it alone, and let it do it's task, and without the so-called security issue with kexts.

I've never used the Cindori's trim enabler and it's always worked but I've not put 10.10 on anything yet..

Correct. I think the idea was you could enable it once or twice a year, then manually TRIM with fsck, then disable it. This way you are not running all the time with the Yosemite kext security feature disabled.
 
I would NOT buy an SSD from a smaller player just to get TRIM.

Those who rush to buy this really don't know anything about SSDs except for maybe what they read on the review sites. Or they are willing to be a guinea pig for the rest of us.

Not all SSDs are created equal. Many of the SSDs made with identical 3rd party controllers may operate similarly, but you cannot vouch for the quality of the contract manufacturer that is slapping this together for them in Asia.

I buy Samsung SSDs exclusively today for use with Mac OS X and other applications in my home lab. I always compare and shop Intel and amd willing to look at Toshiba as well, but Samsung continues to win.
 
I've had a chance to install and test the 512GB version of the "wrk for Mac" SSD from Angelbird. I can confirm it does indeed support TRIM on Yosemite! The OS thinks it's an Apple branded SSD. It formats to the full 512GB. The best part?! It's only $299

For those of you who are interested.. I talked to the owner and he is giving everyone 3% off through 11/31 by using the coupon code "JAPHETH" at checkout. (angelbird.com) :cool:

Let me know if you guys have any specific questions.

While I see your point, these drives are made in Austria by Angelbird.. They are a well known manufacturer in the niche high end SSD market.

A little quick research shows that they are using a 3rd party controller (Silicon Motion SM2246EN), so in effect this SSD is little different from PNY, Corsair or ADATA offerings.

I commend any company trying to manufacture electronics in Europe, but they really haven't added any intellectual property to this device. They are assembling components. It's a good product, if you are willing to run an SSD based on the Silicon Motion SM2246EN controller.

This is very similar to a high end car company going "down market" and releasing an entry level vehicle that is really rebadged from a different manufacturer.

Yeah. I've only ever used Intel and Samsung.
