Use Bitlocker or not?

Just curious how many people choose to use bitlocker or not. The SP3 could easily be stolen but with it such a closed up system, I would assume most thieves would be more interested in reformating the harddrive versus trying to tear up the SP3 and extract the harddrive to read the data. Thus, is a Windows password secure enough to prevent this scenario?

I have read that Bitlocker does not have a noticeable performance hit, thus, are are any good reasons not to use it? Does it play well with most software?

Thanks.

You can use BitLocker only on a subset of all your data.

For example, I have 3 partitions: one for system, one for work information and one for personal stuff. Only the work partition is bitlocker-enabled because it contains confidential information. This way BitLocker does not slow down the system at all, while still providing protection on the data that needs protection. I don't care if anyone gains access to my pictures, but I do care if someone steals the confidential work information.

My SP3 came with bitlocker turned on by default (on the c drive). I think my ATIV 500T did as well. The performance hit isn't as noticeable for light duty stuff. Though I imagine if you did things that wrote tones of data to disk, you would want to turn it off.

Thanks all. I was not sure if it came enabled by default or not so it is nice that Diamond.g has confirmed that his did. Also I like Kevin's suggestion to partition and just enable Bitlocker with the data partition.

On any Connected Standby enabled machine it is required that Bitlocker be enabled OOB, the Recovery Key is stored online in your Microsoft Account unless it a Domain Joined Machine and the domain is configured to store the recovery key in Active Directory.

I use it, I don't notice any performance hit. I am surprised by what unruledboy posted, those numbers point to a lot of overhead.

I use BitLocker on mine (company requirement) and it is totally seamless. If there is any sort of performance hit, it is imperceptible in daily use.

I use bitlocker on external usb hard drives. Thought being if they got stolen, at least the data encrypted.

Interesting specs from unruledboy on degradation due to bitlocker.
