Line for Apple Store in Arlington Selling iPhone 3GS

Because Apple and AT&T allowed people to pre-order for delivery, the line for the new iPhone 3GS at 7am today at the Clarendon Apple store in Arlington, Virginia, was about 10% of what we saw for the original iPhone and 3G.

In many ways, this was a less significant upgrade than the upgrade to the 3G. Key selling points of the 3GS include: faster speed (network and phone), video recording, better battery life, compass, and higher quality camera.

Several other upgrades are available to the previous iPhone through the recently released iPhone 3.0 OS. The new software includes cut and paste, photo messaging (available later when AT&T enables it), universal search, and a voice memo app.

I’ll probably buy the 3GS in several months when I qualify for the cheaper upgrade price.

Swine Flu on Google Maps

There is now a Swine Flu Google Map at http://swinemap.org. Black indicates confirmed deaths from H1N1. Grey are unconfirmed deaths. Red are confirmed infections. Pink are probable infections. Blue are influenza-like illnesses. As of this writing, North Dakota looks like a good place to set up your post-apocalyptic compound while you develop an anti-swine flu serum.

Mac Software Striping RAID Performance

The Mac OS includes software RAID options.  Using the striping option, you can double your storage and greatly improve your read/write performance.  But what is the true performance gain and is it worth doing?

Mac Pro

What you need

First, you need a Mac capable of holding at least 2 drives.  This is actually a problem for most Macs.  Only the Mac Pro is capable of that off the shelf.  The Mac Mini can be hacked to do so but it involves removing the DVD drive and soldering in a 2nd hard drive.  The system I used in this test is the latest entry-level Mac Pro from early 2009.

Second, you need another hard drive.  The Mac Pro can actually hold 4 but for the purposes of this test, I’m only adding 1. This Mac Pro comes with a 640GB Western Digital Caviar Blue so I purchased another identical to that.  It is best to have 2 identical drives when doing striping so that both drives can be fully used.  If you’re looking for Mac Mini drives, we recommend the 500GB Western Digital Scorpio Blue.

Backup original drive

In order to add the 2nd drive, you’ll need to fully backup your first drive so that you can restore it later.  When creating a RAID setup, the drives will be wiped clean.  If you already have a time machine backup, you can do a restore from that but I prefer using Disk Utility to do a backup and restore because it can create a fully bootable 100% identical backup that you can then restore from Disk Utility off of a Leopard boot disc.  Disk Utility doesn’t word things very well.  Both a backup and a restore are both under the Restore tab.  When you backup, you just do a restore from your Macintosh HD to your external backup drive.  If you want the backup to be bootable, be sure it is partitioned with a GUID Partition Table scheme under Options.

Add the drive

Now that your data is backed up, you can add your new drive.  In the Mac Pro, this is the quickest and easiest hard drive addition ever.  Simply unlatch the drive holders and slide one out.  There are 4 screws already in there waiting to go into the new drive.  Then you just slide in the new drive and that’s it.  If you’re using a Mac Mini, you’ll need to follow this Mac Mini upgrade guide.

Mac RAID

Create the RAID
Boot up the mac off of a Leopard disc by holding down C.  Choose your language and then you’ll be able to launch Disk Utility from the top menu.  Select one of the drives and go to the RAID tab.  Enter the RAID Set Name to be the standard drive name Macintosh HD.  Then drag both of your drives to the RAID set window.  Both will show up and show the combined storage based on your RAID type.  Mirroring is for a duplicate backup.  Striping is for performance and extra storage.  You can select Create to create the software RAID and it shouldn’t take more than a few minutes.

Restore

If you did a time machine backup, you can go through the standard Leopard install and choose restore from time machine.  If you did a disk utility backup, select your new Macintosh HD volume and go to the Restore tab.  Choose your external backup drive as your source and the Macintosh HD as the destination.  If you have a lot of data, this can take several hours.  If all went well, your system should now be able to boot off your new striping RAID Macintosh HD volume.

Performance

Now that we’ve got our striping RAID, how does it perform?  Using the Xbench disk test, the drive performance has gone from a score of 73 to 112.  That’s about a 53% improvement overall.  The test uses a variety of disk usage and this striping will perform differently based on exactly how the data is being used.  The biggest benefit will be for large files.  For example, if you use a virtual machine like VMware Fusion, the virtual RAM is written and read to the hard drive when you do a suspend or resume of the OS.  The result is that with a striping RAID volume, this feels about twice as fast. Striping also combines the drives so you double the capacity.

The down side

The biggest negative is that with 2 drives required to be working, we’ve doubled the likelihood of the Macintosh HD volume failing.  If just 1 drive breaks, the whole volume is lost.  Fortunately, Apple provides time machine which gives us a reliable and effortless backup.  If you do lose a drive, you’ll need to replace the bad drive and restart the RAID set from scratch and restore.  Another downside is that because this is a software RAID, it does use a little CPU which hardware RAID would not.  But a Mac Pro hardware RAID card will set you back $700 and the CPU usage is so small, I can’t even notice it when looking at Activity Monitor.

Conclusion

If you want to massively improve your disk performance, adding a second drive and creating a striping RAID set is a great choice.  This is easy in a Mac Pro but can be done on a Mac Mini with some work.  Just be sure you always have a time machine backup running in case your RAID fails.

2009 Mac Desktop Benchmarks

The latest versions of the Mac Mini, iMac, and Mac Pro all show improvements over previous versions.  Besides a few changes in connections, physically they are relatively unchanged.  The main improvement is in performance.

With the upcoming release of the next Mac operating system, Snow Leopard, the threading performance of your Mac hardware is now more important than ever.  Snow Leopard will be more optimized for multi-threading than any of its predecessors.  The latest Mac desktops will benefit more than previous models since they outperform significantly on thread benchmarks.

The following benchmark scores were collected by the popular Xbench Mac benchmarking software.  The new desktops are all of the entry level models. For all tests, a higher score is better.

Model Thread Test UI Test Memory Test
2006 iMac Core 2 Duo 2GHz 171 257 133
2009 Mac Mini Core 2 Duo 2GHz 231 258 162
2009 iMac Core 2 Duo 2.66GHz 360 379 177
2009 Mac Pro Xeon 3500 2.66GHz 543 409 374

It should be no surprise that the Mac Pro performs the best.  The Mac Mini has always been underpowered but at least it still outperforms some previous iMac models with similar CPU.  The entry-level iMac for $1,199 posts extremely impressive results.  For half the price of a Mac Pro, the thread performance was still great.  However, the Mac Pro truly dominates in the memory test.  The newer nehalem architecture uses tri-channel RAM which is significantly faster.  Any memory intensive applications will see a big improvement on a Mac Pro.  The iMac and Mac Mini won’t use nehalem until the end of 2009 at the earliest.

It is hard to highly recommend the Mac Mini just because it feels like it should come with a faster than 2GHz processor.  For the first time though, you can hook up 2 monitors to the Mac Mini.  The iMac offers the best value by far.  It performs great and isn’t overly expensive.  If you want the best performance and money is no object, the Mac Pro is for you.  Once Snow Leopard comes out, the performance of these new Macs should increase significantly.

Music Studio Basics

Since I started working with music studios 20 years ago, I have seen what would have cost $100,000 with reel-to-reel tape equipment now come down to $10,000 with computers. Even more amazing is that home studios which used to rely on muddy sounding 4-track cassette recorders can now produce inexpensive high-fidelity recordings through a computer.

Music StudioAt Tech DC we have setup several music studios, from small one-mic setups for podcasters to 26 simultaneous channel studios to record entire live bands.

The first question to ask yourself when setting up a studio is Mac or PC. While great software exists for both platforms, the Mac is generally more popular for musicians.

While recordings can be done using a laptop, generally you will want a more powerful system in order to add more channels and effects. Effects like reverb can be very processor intensive. If you don’t have an isolation booth, remember to get a quiet computer so that it’s humming doesn’t leak into your recordings. This is another reason that Macs tend to be popular.

The software that records both audio and MIDI (keystrokes, pressures, pitch, etc.) is typcially referred to as a DAW (Digital Audio Workstation). These include Logic, Cubase, ProTools, Cakewalk, and many others.

Logic & Logic Studio (Mac)

Logic was made by Emagic, then bought by Apple in 2002. It is my current favorite and the Studio version comes with loads of virtual instruments that can be played via MIDI.

Garage Band (Mac)

This is easy to use and included in the iLife suite. It is still very powerful and is built using the same engine as Logic.

Steinberg Cubase Software (PC & Mac)

Cubase is an excellent DAW for PC users.

Keyboard Controllers

Korg, Roland (and Edirol), Yamaha and others make keyboard controllers that can be used to control virtual instruments. Depending on the type of music, this can be very helpful. Virtual instruments come with DAWs and can be added on separately. They vary from unreal synthesizer sounds to professional pianos and organs.

Midi and Audio Ins and Outs

PreSonus of Louisiana makes the Firebox that is inexpensive, small, and perfect for very small studios, assuming that you need no more than a couple of Mic/Guitar inputs at a time. For larger studios, they make the 26 channel FireStudio.

M-Audio is a popular name in Audio/Midi interfaces as well as keyboard controllers. They have a 26 Channel ProFire Audio interface and a smaller 6 in X 10 out Firewire interface.

Mackie has long been the most popular brand for mixers. The mixers can be used to send mixed down audio to a small Audio I/O box like the Firebox. Mackie also sells digital Onyx mixers that send multi-channel audio to a computer.

Mark of the Unicorn is another old name in audio and currently sells the Traveler-mk3 audio interface.

Where to Buy Stuff around DC

There is no one perfect solution for everyone. You need to look at your budget, recording needs, and see what hardware and software you are comfortable using. Check out these stores to see the equipment in person.

Chuck Levin’s Washington Music Center is my favorite local store for instruments and equipment. It has been here since 1958. Other local stores to visit are Guitar Centers in Falls Church, Virginia, Fairfax, Virginia, and Rockville, Maryland (formerly a Venemin’s Music).
