Hi all,
Does an i7 over an i5 significantly increase overall performance when using FileVault...?

I am leaning towards:
27" i5 3.3 GHz, m395x with 4GB RAM, 512 Flash.
I will use office applications, technical design applications and games, so I don't think I would have much use for an i7.

However, I would like to have my main volume encrypted, so use FileVault. Are there any benchmarks/statistics comparing i7 vs i5...? Tnx...!

Thank you for all the wealth of content and thoughts in this forum.

I have FV enabled on my rMBP and the overhead is not noticeable at all. I'd not get an i7 just in the hopes that it will help improve the performance of FV.
 
A quick question on fire vault. I am considering starting to use it but have some concerns about my existing backups. I use both time machine for local back up and Crashplan for external backups. Will a conversion to fire vault mean these backups have to be redone. Also Crash plan is already an encrypted backup how will this work with fire vault?
 
I can't speak about crash plan but by default TM does no encrypt your backups. You can select that option, though I suspect it will only encrypt new backups and the old ones will remain as the are
 
I think the whole TM partition will be encrypted if you choose to encrypt a new backup, because there is no option for backup encryption if the disc is already formatted as OS X Extended (Journaled and Encrypted).

But I am not 100% sure about that.

Why do you think you need file vault in the first place?

I am interested to know why you would want to encrypt your main volume in the first place? You may have a perfectly good reason but in my experience it can cause mor problems than it solves.
 
For peace/ease of mind and compliance with security standards. Some of the material I work with needs to stay confidential, even in case of burglary. I prefer a complete solution to looking into whether every application plays by the rules (not using temporary storage on an unencrypted main volume) or having to configure this manually.

My laptop is encrypted using FileVault 2 and I've never had a problem with it. What kind of problems are you referring to? Tnx.
