SSDs and TRIM

Easily added.

Snow Leopard users should be aware of Apple’s latest sleight of hand.

TRIM – garbage management for SSDs which maintains their performance – has been added in Snow Leopard 10.6.8, the last version of Snow Leopard before Lion comes to market in July, 2011.

But that’s not all good news. You see Apple, in its greed for every penny they can squeeze from buyers of its overpriced jewelry passing as computer hardware, has made sure that TRIM support will only be available if you bought your computer with its SSD from Apple. Meaning you were well and truly hosed down at a 100% premium compared to what you could have bought an SSD for yourself. Or, worse luck, maybe that SSD option was simply unavailable when you bought your hardware so now you are forced to use an aftermarket SSD to upgrade. No TRIM for you, my lad. So much for backward compatibility and planned obsolescence.

Apple has made it extremely easy to replace HDDs in MacBook Pros and MacPros (and extremely hard in iMacs and Minis) but if you slot that nice new SSD into your MBP/MacPro/Mini, TRIM will not work. Upgrading your HDD to an SSD in your MBP, a plug-and-play operation which does not invalidate the warranty, is the single best thing for the performance of your laptop. However, when you do so, this is what OS 10.6.8’s System Profiler will report:

No TRIM for you, sucker.

Mercifully, there are many smart people out there who believe in freedom of speech and refuse to be stolen from. Hop over to the good people at Groths and you can download their utility and have TRIM up and running on your aftermarket SSD in no time at all. My SSDs are recent Intel X25-M 120gB models, and this fix works perfectly on both, after a restart.

As usual with these things, I suggest you try this on a bootable backup drive first, to be on the safe side. After you complete the installation, your System Profiler->Serial-ATA->SSD should look like this, and your SSD’s performance will be enhanced for the long term:

TRIM enabled on the HackPro.

As you can see, the fix uses no space, merely modifying existing files, speaking loudly to Apple’s increasingly cynical attitude toward its customers.

If you have been using your SSD without TRIM for a while, as I have, Lifehacker has information on how to clean it up here.

Moom

Fixing the green blob.

One of the weakest features of Apple’s OS X operating system is the Finder. It has never supported split windows, though that was put to rights with Total Finder which I have been using for six months now and recommend unreservedly. True, it’s $15 for something which should come with OS X, but the makers do a stellar job of keeping it updated for each new OS major or minor release and once you have used it there’s no going back if smooth file movement between drives and directories is your thing. TotalFinder addresses one of the few remaining shortcomings of OS X.

As for the other major one, well, it’s a ‘feature’ which didn’t work in Cheetah, OS X 10.0. And it has continued broken in all of Cheetah’s successors – Puma, Jaguar, Panther, Tiger, Leopard and Snow Leopard.

And I’ll bet you it will not work in Lion.

I am talking, of course, about the wretched green blob. It’s the colored ball toward the top left of every window you open in OS X.

Clicking it is meant to expand the window to full screen. What could be simpler? .

Except that clicking it has results about as predictable and consistent as the pronouncements of your elected representative. Meaning it simply cannot be trusted as what it does seems to vary with the day of the week, the weather and the demeanor of your dog. Maybe it needs a good bribe, like your Congressman or Senator, to actually do what it’s paid for?

And if, like me, you have no fewer than three displays with multiple windows attached to your computer, then moving windows around is a real pain. But I know better than to complain to a company which rarely listens to its customers and curse quietly every time I try to grab the window size repositioning area at the lower right of an open window, miss, try again, then curse some more when moving the window into place, only to find that I have to resize yet again.

So I have given up complaining about the green blob, having long ago assumed that it’s just one of those non-facts of life like US military intelligence (MIA), US Energy policy (none) or the US electoral system of one-man-one-vote (in the US we have one-dollar-one-vote).

Well, with Moom, the green blob finally works. And it works as well with multiple displays as with one.

Moom accomplishes what none of the alternatives does. A simple and intuitive way to make any window full screen, properly positioned. Or half-screen come to that, which is even more useful. For real masochists, you can even go to quarter screen or any rectangle or position of your choice. Moom allows you to program any shape and position you like and those will be added to the pop-up-on-hover, below. The implementation could scarce be improved upon. Just hover your mouse cursor over the green blob and this is what you will see:

The rest is self-explanatory.

It works perfectly, and the download gives you 100 free goes. Thereafter it’s $10.

And as for you, Apple, you can kiss my Moom.

Another SSD for the HackPro

Gearing up for Lion.

As OS X Lion will likely involve the usual amount of experimentation to get it working properly on the HackPro, I have added a fourth drive to the computer and its second SSD, so it now contains two SSDs and two HDDs.

The SSDs act as OS and application drives (boot and back-up) whereas the HDDs contain data and back-up data. They also contain OS Snow Leopard as EyeOne Match, the profiling utility for my EyeOne colorimeter, will not work with Lion.

In addition to having an SSD for experimenting with Lion, I also gain a super-fast back-up boot drive. On monthly testing of the HDDs as boot drives I have been increasingly struck by just how slow these are when booted from. After four trouble free months with my first Intel SSD it made sense to add a second. For the test phase I will partition it into two partitions, using Disk Utility; one will contain a straight clone of the existing SSD boot and application drive, and Lion, once released, will reside on the other until fully debugged. Thereafter both will be converted to Lion and Snow Leopard will remain on the HDDs for use with EyeOne Match.

The second SSD will continue to act as a low risk testbed for any new software changes or upgrades.

This is how things will look:

Drive topology after adding the second SSD to HackPro.

I strongly recommend you add an SSD to your work computer. Once you have experienced the speed there is no going back. I paid $230 for each Intel X25-M 120gB SSD.

The HackPro with two SSDs installed.

The incremental heat output and current draw of the second SSD are so low that no additional cooling precautions need be taken in the exceptionally well ventilated Antec Sonata III case with its generously spec’d 500 watt power supply. Installation, which means attaching the SSD to the provided mounting plate and the plate to the Antec’s slide in carrier, plus the connection of power and data cables took FU Steve all of twenty minutes. Carbon Copy Cloner took 27 minutes to clone the existing SSD Boot drive to the new backup SSD, and it needed but two more minutes to verify that the backup was bootable and to add the backup job (Boot->SSD Bak) to Carbon Copy Cloner’s list of automated, nightly backups. You really don’t want to forget that last step!

Partitioning:

As the new backup SSD will also be used as a test bed for OS Lion, to be released next month, I first partitioned it into 90gB and 30gB partitions, using Disk Utility. The latter partition, named ‘Lion Test’, at 30gB, will be more than large enough for OS and selected application testing.

TRIM:

TRIM is the software code which helps manage garbage on an SSD drive. Apple’s just enabled it in OS Snow Leopard 10.6.8 (the last release before Lion) and it will be included in Lion. At this time the OS will only permit TRIM to be used on Apple installed SSDs. Let’s hope that changes, as many Mac users will be replacing the HDD in their MacBook Pro with an aftermarket SSD to avail themselves of the enhanced speed and lower power consumption. Even if Apple does not step up to the plate here, hacks already exist to make TRIM in Lion work with non-Apple installed SSDs.

Meanwhile, is there anything useful to be divined by comparing the space on the 3 month old SSD in my HackPro with the newly installed backup SSD?

Here’s are the drives inside HackPro as reported on the Desktop:

HackPro drives before partitioning SSD Bak.

In the case of the SSD drive pair, the base drive reports a little more space than the backup one, but not enough to make any difference. Both the backup drives, which include a full Snow Leopard OS, are bootable. So after three months of intense use of the first SSD (top of the above screen snap) there seems to be negligible difference in available space, suggesting that the absence of TRIM has made no material difference. However, be assured I will be looking into adding TRIM support once Lion is installed and will be explaining how to do that in these pages.

Brown bagger

A spot of luck.

I was gazing at this fine mural off 24th Street in San Francisco, trying to figure out the meaning of the bubble or raindrop between the fingers, when the pedestrian chanced along.

Mission District at 24th and York. G1, Olympus 9-18mm MFT @ 18mm, 1/800, f/7.1, ISO 320.

He glanced up for a moment and I had the snap.

The Olympus 9-18mm MFT lens is great for this sort of thing; it focuses almost as fast as the 14-45mm Panny kit lens and what distortions it leaves behind are easily fixed in LR3 using my custom, downloadable correction files which you can find here. The lens is an outstanding optical performer, especially given its pocketable size. Optically it is easily the equal of the kit lens, which is to say very good indeed. And at 9mm (18mm FFE) it’s as wide as you need in all but the most demanding settings. While Panny’s considerably costlier 7-14mm MFT goes quite a bit wider, there’s no way to protect the protruding front glass with a filter, so Panny’s glass does not pass my ‘throw it in a jacket pocket test’, given that I have no inclination to futz with lens caps.

The only drawback the 9-18mm Oly has compared to the kit zoom is that there’s no OIS and you have to extend the lens from its collapsed position for use. If you forget to do that the G1 will refuse to work.

The ‘new’ Leica M9P

What a scam.

It’s five years since I sold my first – and last – Leica and sadly the former German masters of design have given me no reason to regret that decision.

You thought $7,000 for a camera body with no lens, no autofocus lenses available and a sixty year old viewfinder design, allied with a noisy shutter was a lot?

You are a piker.

Because for a mere $1,000 extra you can have the 2 cent red paper dot on the front (you know, the one that says you are rich and screams ‘steal me and my owner’s wallet’) removed and the word ‘Leica’ engraved in script on the top plate like they used to do twenty years ago. And lest we forget, Leica has made the LCD glass tougher than the one made of pure cheese on the ‘base’ model. Such a deal.

Here’s the latest blurb from the antiquarians at Leica Camera:

Hey, but “Hang on a minute”, you say. I get one of the smallest cameras out there. The factory says so.

Uh huh. And for a bit less you can get a Panny G3 whose modern sensor will rival the M9’s dated Kodak one (so much for a ‘lifetime camera’), offers auto everything, is super quiet and comes with a great choice of lenses, some even branded (if not made) by Leica. No red dot at those prices, though. But you do get a pro-quality movie mode to compensate. As a point of reference, the red outline of the M9 is superimposed on the G3 body below.

And you can buy 13 of those for the price of one M9P or a mere 11 for the price of one regular M9. That way, when your Panny blows after 50,000 exposures you recycle it and pull the next one out of its box. Better still, get smart, buy one, and upgrade to a G4 in 18 months. It will be even better.

As for logo removal, my roll of black electrician’s tape should last the next five generations in Dr. P’s lineage.

A fool and his money are easily parted.
