Buy an SSD Drive to Boost Performance for Under $200

From Consumer Reports, December 2014:

Upgrade My Old Computer or Buy New? Q. I am trying to decide between replacing the hard drive on my 2007 iMac for $250 or buying a new iMac for about $1,350. The old iMac is meeting my needs, and I’ve barely used the storage available on it. But I’m trying to avoid be- coming obsolete. Any advice?

A. We’re big proponents of upgrading before buying new. (One of our experts once upgraded several 10-year-old Windows XP PCs to Win- dows 7, with double the memory.) Apple is good about maintaining compatibility between its computers and its latest Mac OS version. So replace the hard drive. And while you’re at it, install enough memory to bring it up to 4GB: That will boost performance with newer, larger Mac OS versions and applications.

The Geek's take:
Upgrading your older hard drive to an SSD drive is now very affordable, with 250GB drives available for under $150 and 500GB options available for $250 or less.

B&H has a Toshiba 512GB Q Series Internal Solid State on sale for $200 right now.  Just 18 months ago ago, these would cost $300-500.

The Samsung 840 EVO 250GB 2.5-Inch SATA III model is the #1 selling internal SSD drive on Amazon.com, and has been in the top 10 list for many months.  At only $120, this drive is an easy way to swap out an old laptop hard drive.  Average users love it too.  It has a 4.7 out of 5 star rating with over 5,000 customer reviews. The larger 500GB model from Samsung is just $230.

$120 for a 250GB drive = $0.48 per GB.
$110 for a 256GB drive = $0.43 per GB -- Crucial MX100 256GB SATA 2.5"
$230 for a 500GB drive = $0.46 per GB.
$205 for a 512GB drive = $0.40 per GB. - Crucial MX100 512GB SATA 2.5" 7mm (with 9.5mm adapter)

Why Upgrade to an SSD?
They are best performance upgrade for the money.  For $200 or less you can upgrade your operating system drive to run on one of the fastest drives available today.  Your computer will boot almost instantly and applications will also load much faster.

SSD drives have no moving parts, use less energy, and do not generate as much heat, which is one of the things that wears out laptops over time.  If you drop a laptop that contains an older spinning hard drive, there's a good change that you'll trash your drive and loose data. (Unless your drive has a motion sensor to detect falling movements.)

What buyers are saying about SSD upgrades:

Crucial MX100 512GB SATA 2.5" 7mm (with 9.5mm adapter) 
Received my MX100 512GB today and swapped it into my 2009 MBP [MacBook Pro] and put the existing 256 GB 5400 RPM hard drive into an external case. Cloned over the hard drive, enabled full disk encryption, and moved on without any issues so far. Granted it has only been a few hours, but I can see the difference immediately. My 5 year old machine has new life. Bootup went from 3 minutes to 7 seconds. I tend to keep multiple tabs open on my web browser and it definitely is moving faster. I could tell on my old hard drive that I was spending lots of time paging to the disk (even with 8GB of RAM).
