If you're looking for a significant performance boost for your middle-aged laptop, replacing your aging hard disk with a solid state disk (SSD) could give your computer a new lease on life.

Solid-state disks (pictured, bottom) differ from traditional hard disks (top) in that they're not constructed with platters and heads. Instead, they're more like giant thumb drives, containing memory chips designed to be written and re-written without wearing out. The upside to this is that SSDs are much, much faster to read and write to, making booting and starting applications lightning-quick.

I recently installed an Intel X25-M SSD, a 160GB drive, as a replacement for a 120GB Toshiba hard disk for my 2006-vintage black MacBook. Spendy, for sure, but for the performance increase and the extra life it adds to my MacBook, well worth it. Plus, I had my state tax refund burning a hole in my pocket.

The performance is phenomenal. The old disk booted in a respectable one minute, 49 seconds. The new disk booted in a blazing 31 seconds. Ridiculous. Windows also boots in less than half the time it took before. Photoshop CS3 launches in five seconds, Illustrator CS3 in nine seconds.

Getting the drive was simple: It's moving the data that takes time. Read on to see how you can migrate your data like I did -- including a Boot Camp partition -- with little fuss.

Some good soul gifted you with a hard drive for the holidays. I can't think of a better gift! There are two ways to use that extra disk space -- the right way, which I'll get to in a moment, and the way many people do it, which is to just expand their disk space because they are running out of room.

I'm here to tell you that is the wrong thing to do with a new hard drive if you don't have a backup strategy already. Let's make a few assumptions here. The new drive has a USB 2.0 interface, or it has a Firewire 400 or 800 interface. It also is at least as large as your primary hard drive. Even better if it is bigger. Use that drive as a backup device, not for more disk space. Old hands around computers already know this, but if you are just getting started, it really is extra important to have all your files duplicated on another drive.

With any computer, stuff happens, like a sudden power surge, a drive failure, or a kid in the house who loves to see how the Mac trash can works. Can you really afford to lose all those pictures, emails, documents and CDs you lovingly ripped to iTunes? I didn't think so.

Getting a heavy duty back up is not too challenging. If you plug a brand new drive in, your Mac (assuming you have Mac OS X 10.5 Leopard) will ask you if you'd like to use it as a Time Machine drive. Time Machine is Apple's built-in backup solution, and it is great for people who constantly change or update files and sometimes have a good reason to go back and get the old versions. The larger your extra drive, the further you can 'go back in time'. Time Machine allows you to restore all the data, but it can take several hours and may require your original system DVD if your machine isn't bootable.

All day on December 25, TUAW presents "Now What?" We've got first steps and recommendations for all the Apple gifts you (hopefully!) found under the tree today. Happy holidays! If you're a Mac veteran, send a link to this post to the switcher on your holiday list.

Merry Christmas, new Mac owner. First of all, congratulations! Welcome to the family. There's some eggnog on the table, and feel free to put your coat on the bed. Setting up your new Mac is a famously easy experience. It should take about 10 minutes, depending on the kind of Mac you bought, and where you want to put it.

Once you have your new Mac on your desk, it will take you through a short setup process to personalize your new machine. You'll choose a username, a password, and will be given the option to register your Mac and sign up for MobileMe, if you want. (You can register and sign up for MobileMe later, if you don't do it now.)

If you bought any applications along with your Mac (like Microsoft Office, for example), you can install them very easily. Just insert the disc, and either drag the application to your Applications folder (on your hard disk) or double-click the installer application. You can eject the disc when you're done by dragging it to the Trash, or pressing the eject key on your keyboard.

For Windows compatibility, get your Windows XP (SP2 or SP3) or Windows Vista disc ready, and double click the Boot Camp Assistant in the Utilities folder (it's inside your Applications folder). Boot Camp Assistant will walk you through the process of installing Windows on your Mac. It's not difficult, but it will take a little time. Once Windows is installed, you can hold down the Option key before your computer boots to choose which operating system to run, or select a permanent preference via the Startup Disk pane of System Preferences. You can read more switcher-specific tips in our Switchers category.

If you're switching to the Mac platform from the PC, I might humbly suggest you read Part 1 and Part 2 of my experience introducing my dad to the Mac. He was a hard-core PC user until he fell in love with his Mac mini.

There is more fallout from the current Leopard update to version 10.5.6. Many users are flocking to the Apple support forums to share their tales of woe about Time Machine failures after the update. (Ironically, Time Machine was on the list of items that received bug fixes).

Upgraders are seeing Time Machine stall, fail to identify the target hard drive, lock up while Time Machine is 'preparing' to backup, and other assorted glitches. There is no guarantee that these issues were caused by the update to 10.5.6, but users are seeing a lot of problems in parallel to the software changes.

MacFixit has quite a bit of guidance on the Time Machine issues. One of the most interesting observations is the long pause while 'preparing' to backup. It seems TM needs to do a deep traversal of the data because it sees a lot of file changes to copy, as would be expected with a major software update. The advice is to wait it out and and eventually TM is likely to get going. I had the same issue and eventually stopped the process, erased my TM drive and started again. That was after more than 2 hours of 'preparing'. It looks like I might have been better off to wait.

I had hoped 10.5.6 would fix the occasional TM error I get telling me that the backup failed, but then when I try again, everything is fine. I spent a good hour on the phone with Apple support on this problem some months ago, but didn't get anywhere. Many others have seen this rather arcane message and reported it. Hopefully it will be fixed in the next OS update.

It's good to keep in mind that most people updated without any dire consequences, but there are enough people grumbling that it merits a closer look by Apple.

• If your Mac is new: Boot up the new Mac and go through the setup screens. When the setup assistant asks if you want to migrate information from your old Mac, choose "From Time Machine backup or other disk."
  
• If your Mac has an existing account, don't fret. Just open "Migration Assistant" located in /Applications/Utilities.

Good morning, Mr. Phelps. The man you are looking at is Justin T. iPhoneuser, one of our loyal TUAW readers. Recently, Justin's iPhone went kablooey and when he tried to restore, he found that his backups were corrupted. He lost a great deal of data and time, all because Time Machine hadn't backed up his iPhone's data.

Your mission, Jim, should you choose to accept it, is to help Justin back up his data with Time Machine so he never has to face this kind of data loss again. As usual, should any of your team members be caught by Apple, the Secretary will disavow any knowledge of your actions. This post will self-destruct in five seconds...

A German site, Apfeltalk.de has posted screenshots of the forthcoming version of Mac OS X, 10.6 (a.k.a "Snow Leopard"). Most of the screenshots show off the Safari 4 developer preview that will include the "Save as Web Application" option in the File menu.

The website also shows off the next version of Address Book.app that will bring Microsoft Exchange support to the Mac platform. We do however have to speculate about the System Preferences.app screenshot that shows two Time Machine icons with one labled "Dock" and another labeled "Time Machine" -- this seems out of place and unlike Apple.

You can see all of the screenshots (before Apple's legal team gets a hold of them) on the Apfeltalk.de site.
