Beyond the veil of security, and sense of calm I get when leaving my laptop in the car or airport lobbies; the next most important thing to me is performance (after all, running my VMware lab on a laptop with a single drive isn’t exactly cheap). Thus mid last year I invested in a 240 GB OCZ Vertex 2 SSD drive, to run inside my i7 MBP. Encrypting your drive absolutely kills performance, so I did some very un-scientific tests today upon my upgrade to Lion that I wish to share.

Below are several Xbench results for HDD performance only, covering ‘fresh’ HDD, and encrypted. Within Snow Leopard (10.6) with PGP WDE, and in Lion (10.7) with the inbuilt Disk Encryption.

First up as you can see we have the fresh install, and nicely enough, with just an OS upgrade, there’s an increase in the disk throughput. More importantly though, is the encrypted performance. Averaging out PGP vs Lion, we witness a doubling of the MB/s capability within the latter.

On the one hand, its a shame I have a license for PGP that I spent ~$175AUD, on the other, it served its purpose, and is now going to be replaced by something that comes free with the OS, and performs better.

Going green? Or going neat? Get rid of that paper!

Think of all the bills, invoices, warranty cards, tax refunds and bank statements that you file away, day after day. The problem here is that paper is bulky, and takes up a lot of physical space, especially if you’re an owner of a filing cabinet.

My hope for this task was to achieve a state where I can be light on my feet, Read more »

Am soon going away on a little trip, over to Europe, through Tokyo. Wishing to record my trip, as well as have some data for geocoding the photos, I went on a quest to find a GPS unit that allowed me to:

• log data to internal memory
• make sure there’s LOTS of memory
• and lots of battery
