So, today at work I had a little bit of idle time to find out the exact effects of Microsoft’s encryption technology “Bitlocker” on Windows 7 Enterprise. Having my computer encrypted gives me a safer feeling about walking around with sensitive data, not to mention the fact that some companies require to be compliant when it comes to security measurements. To see what the effects were on encrypting my SSD I did a test run of CrystalDiskMark http://crystalmark.info/ before and after.
See the results below:
Note that the differences between an encrypted disk and a unencrypted disk is not that large. Which is a proof to me it is safe to walk around with an encrypted disk. The test was run on a HP Probook 6560b with an Core i5-2410M and 8 Gigabytes of memory.

Alright, so last month I received a new laptop for my work. It’s the fantastic HP ProBook 6560b with it’s slick design and high resolution (ahum 1600*900) panel.
But what’s the use of a new laptop with a i5 cpu and 8 Gb’s ram but a slow harddrive? So I bought a Crucial M4 128 Gb SSD and off course without doing any ‘RTFM’ or digging on the internet about ‘compatiblity issues’ I plugged my SSD right in my notebook to experience that my SSD was not detected <insert sad face>
Out-of-the-box my Probook 6560b has bios revision “F.20” and there was a bios update (F.22) available right from the HP product and support site. After flashing my bios in Windows to the latest revision (on my old hard drive), my SSD got detected right away and all the fun could begin!
