MBP and filevault

So it doesn't apply today?

It doesn't apply today. This was the case when it was on Macs with processors that didn't support AES-NI, like the Core 2 Duo ones.

Meanwhile, all Core-i Macs have AES-NI, so the claim is no longer valid.

Any thoughts on this?

This post a few posts up in this thread answers that:

Doesn't tax it much. On my late-2013 13" rMBP, speeds were:

1. 750MB/s read, 720MB/s write w/o FV.
2. 730MB/s read, 690MB/s write w/ FV.

So not too much.

No. This was for the core-i macs, while for older cpus its even higher. At least that what it says.

But with that said, note that Filevault is not supported with Diablo.

Hmm... that's odd. I wonder why. Once you login and the disk is unlocked the file system works normally with third party apps like that game.

Nope. See my post #7 above for some tests.

FWIW I have File Vault turned on in my 2012 cMBP and it runs fine. The only time I notice any hit in performance is when logging in from a reboot or cold boot. It takes maybe 2 seconds longer to decrypt and login.

It also has a Samsung 840 EVO SSD too. I suppose if it had a normal HDD one would notice the hit more.

I still disagree. When I tested it on my own Macs, the performance delta was never that big.

There is no visible performance hit from FV2 being enabled on modern systems (2012 and up, usually— core i systems). Even if there was, it is easily outpaced by massive biannual SSD improvements in random R/W.

FV1 had much greater performance hits, but it was also used on older hardware.

Also, the majority of people simply MUST encrypt their drives today because so many sensitive transactions are done on them. Taxes, banking, etc. There's enough on most peoples' laptops to steal their identity if you don't encrypt it and it gets stolen.

EDIT: sorry, I mean 2011 and up MBP systems. Core i processors have the hardware ability to take on FV2 in stride.

Hm im really in a dilemma whether i should use FileVault or not now. The thing is my Mac is mostly at home so i don't know if its worth it on the other hand if there is no perceivable performance loss I'm thinking why not.

Do you have a Core i processor? Then yes, use it no matter what.

If you don't, and the laptop isn't moving from your house, don't worry about it too much, but try it on for size.

Yes i do, a Haswell rMBP. I decided to turned it on and its now just in the process of encryption. Thanks for all the information from all.
