OS X V10.7 Lion :: FileVault 2 And Disk Speed Tests
Jun 23, 2012
I have had FileVault 2 enabled on my MacBook Air (late 2010) and have been running regular disk speed tests using Blackmagic.Â
This week I bought a new 2GHz Air with 256GB disk and ran Blackmagic, which showed impressive 453/404 MB/s speeds. All well and good. Then I switched on FileVault 2 and decided to repeat the test to see if there was any speed degredation as a result of the encryption. Now I get an error message that the Air's disk is "read only" and Blacmagic cannot run. If I had had problems on the old Air I would have assumed FV2 was the culprit.

i do have an urgent problem with my macbook pro. for some days its tellingme that my startup disk is full. therefore i cleared about 14 gb of space from the 500 gb disk. next day i controlled via get info and i could literally see the space being used up again in ca 40 min. so i googled around via my phone since the mac did not show any websites anymore...
so i know now that it is not the time macine since i do not use it as also any idisk or any other backup software/hardware
i downloaded grandperspective and found this sparsebundle file of incredible 418Gb size made of many many numbered files of 8,4MB each fromca 10 different dates since i have the mac.Â
i am new to mac and an old dos user therefore i do not know how this bundle is designed or if i can delete files of this band folder. i googled that this file is from FileVault and therefore reconstructed everytime i log out. i do at times hard reset the mac(5secs power button) when its not as fast as i want or blocked by too great 3d files i work onold dos habit. could these be leftovers?
please please help me with this issue since i have to work and like that the beautiful mac doesnt even open up websites..

When both Mac OS X 10.6 and Windows 7 were tested on a MacBook Pro, Apple's new operating system clearly beat Microsoft in terms of speed, a new test has shown.
Both operating systems were tested on a 2008 MacBook Pro machine by CNet, and each was given its own, separate, clean hard drive. The 64-bit version of each OS was included in the test, which measured a variety of speed and performance related tasks. Snow Leopard was given true, full 64-bit support with most of its native applications taking full advantage of modern processors.
Each OS had the same software installed: iTunes 9, QuickTime, Call of Duty 4: Modern Warfare, and Cinebench R10. In the test, Snow Leopard booted and shut down significantly faster than Windows 7.
"In time-based tests, Snow Leopard consistently outdid Windows 7," the study found. "It took only 36.4 seconds to boot up, while Windows took 42.7 seconds. In a shutdown test, Snow Leopard took only 6.6 seconds, while Windows needed twice the amount of time: 12.6 seconds. Both computers, however, took just about 1 second to return from sleeping. For this reason, I didn't actually test the wake-up time as it was too short in both operating systems to produce meaningful numbers or even allow me to measure the difference."
The Mac software also unsurprisingly ran Apple's own native applications more efficiently. Converting a movie from M4 format to iPod in Quicktime X on Snow Leopard took 444.3 seconds, while Windows 7, with QuickTime 7 (the latest version available) took 723 seconds. Similarly, converting 17 songs in iTunes from MP3 to AAC took 149.9 seconds in Snow Leopard, while Windows 7 required 162 seconds.
The test also found that Mac OS X 10.6 had better battery life on the MacBook Pro than Windows 7. The 2008 model has a removable battery. But author Dong Ngo said he believes Boot Camp drivers were mostly responsible for the Windows 7 battery life, as many PC laptops fared much better than the 77 minutes the Microsoft OS fared.
One area where Windows 7 was able to easily trump Snow Leopard was in graphics performance. The system's 512MB Nvidia GeForce 9600M GT graphics card helped the system score much better in the latest version of Windows, earning a 5,777 3D rendering score in Cinebench R10. Snow Leopard scored 5,437.
In testing Call of Duty 4: Modern Warfare, Windows 7 again came out on top, with an average 26.3 frames per second performance, compared to 21.2 frames per second within Snow Leopard.
Ngo's conclusion: Unless you are a gamer, get a Mac.
"If you can get by with just software designed by Apple and if money is not a big issue, you will be happy with a Mac," he said. "Examples of these software choices are iTunes, iLife, QuickTime, Safari, iChat, and so on (and you probably won't need much more than those for daily entertainment and communication needs). Finally, if money is not an issue--and it definitely is for most of us--you should get a Mac anyway. It's the only platform, for now, that can run both Windows and OS X."

Long time lurker, first time poster.
I received my 500GB Seagate Momentus XT yesterday and ran some quick and crude benchmarks that I thought I'd share with you guys in case anyone else was thinking of upgrading. Here are my observations.
With Factory Seagate 7200rpm 500GB Drive:
-------------------------------------------
Time to boot measured from hitting the power button to when the finder toolbar appeared at the top averaged approximately 40s to 45s.
Running Photoshop CS5 immedately after reboot took approximately 10s.
The above two tests were repeated about 4 or 5 times and were fairly consistent.
With new Seagate Momentus XT Hybrid Drive:
--------------------------------------------
Time to boot measured from hitting the power button to when the finder toolbar appeared at the top averaged approximately 30s.
Running Photoshop CS5 immedately after reboot took approximately 3s to 5s.
The above two tests were repeated 4 times (sorry I ran out of time to run more) and as expected the first attempt was a little slower than subsequent tests. The times listed above represent the times I was getting after the first reboot.
All in all i'm happy with the improvement, especially when i consider the fact that I still get my 500GB capacity. I wanted an SSD but couldn't bring myself to fork out the money to get a drive with enough capacity to meet my needs.
If you have any questions or want me to run specific tests let me know. Not sure about running battery life tests since my battery-o-meter is all over the place telling me i have anywhere between 2 hours and 8 hours of battery life depending on what i'm doing at any given moment

For some reason, Apple marketing has left out a very import bit of information regarding the sale of Flash based storage. The specs of our flash storage is and was as important as the RPMs off our mechanical drives. As most of you know, shopping for SSDs is like wading through a sea of speed tests. Yet for some reason, Apple is not forthcoming about the IOPS, Read, and or Write speeds of their flash media. There have been endless reports about Toshiba and Samsung based flash media being shipped with iMacs and MBPs with different speeds. I think the earlier brand being a slow dog most of the time. Â
I called Apple yesterday and got the, we don't have that information sir. I also send an email to feedback explaining that it's probably a good idea to let professionals who are spending nearly 4000$ USD for a rMBP to know the specs of the storage so we can know if it meets our speed needs. With all that said, I welcome all of you to post speed tests of your rMBP. You can do this with 2 tests that I am aware of. If anyone knows of others, please let me know. Please also post your basic model specs, like rMBP 16GB 768GB?
1. Reboot with no apps open
2. Then run Blackmagic Speed Test or AJA System TestÂ
I'm sure the results will not be the same each time you run the test, but over a few tests, you can come up with an average. You might not be able to run the test directly on your drive since Lion has locked us out of our own hard drives, so you might need to pick a folder in your user folder. Â

I recently upgraded to Yosemite and now have to enter my password every time I boot up with I find annoying. It seems I need to disable FileVault to solve this problem but when I try I get a message ' FileVault is encrypting the data on your disk. Wait until your disk is fully encrypted before turning off fileVault'.

I turned file-vault on in Mac OSX Lion 10.7.3 and now I am presented with log-in screens 2 times whenever I reboot my mac. First log-in screen comes immediately, is a light gray screen with filevault-enabled users, so I enter my password there and after some time I am presented with a second normal log-in screen, dark gray with all users. After entering my password in this second login screen, I am able to use my mac. Â
I am wondering if this 2 log-in screens is the normal behavior after turning on the filevault 2 on in Mac OSX Lion?

I've just turned File Vault on on my MacBook Pro 13". I've followed all the steps: noting the FileVault Key, storing it into Apple and restarting my Mac. When my Mac has started, it has asked me for my login, and everything goes OK until the moment my desktop appears. At that moment in time, my Mac hangs, and I get the "colourful beach ball" and nothing seems to happen. I do have a backup on my Time Machine and I can format the disk and start over, but I don't understand why my Mac is freezing just because I've turned FileVault on.

given the disaster with FileVault 1 under 10.7.3 (passwords logged in plaintext in secure.log...) I changed my laptop to FileVault 2. But now I can't enable a guest account anymore. Have I lost the guest account on this system?Â

Is it safe to use FileVault 2 on a SSD that has been installed after purchase, not an SSD that came with the MacBook? Can FileVault be undone if the performance is no good?Â

I've enabled Filevault 2 on my Lion primary HD. When scanning my disk with Disk Utility, it tells me that I it needs to be repaired and that I need to reboot my Mac and hold CMD+R keys, then enter Disk Utility in "restore mode" of Lion. So that's what I do: I restart my Mac and enter restore mode. Now, to fix my drive, I need to unlock it. In Disk Utility, the disk is greyed out and when clicking on it, a "unlock" button appears at the top. I've tried every possible password I know (including the restore key), but I'm UNABLE to unlock my HD.Â
Funny thing is that I know my password is right, because I can select the Change password feature in the File menu and it works well. But the new password can't unlock the hard drive! when Filevault 2 is enabled, how can I unlock the drive to scan and repair it? Is there a bug in this feature?

Since I activated FileVault 2 on my Mac boot drive without initializing it, I'd assume that the same thing could be done for any other drive. I've got some external drives with hundreds of GB of data which I'd like to encrypt. Disk Utility lets do it by erasing the drive and encrypting the data written afterwards.
Is there any hidden feature that allows one to convert the drive without erasing it first, like the FileVault utility did for the boot drive (even when working on it!)?

I had used FileVault 2 on the entire drive and had later deleted all contents. After changing my mind, I used SoftTote Data recovery for mac to retrieve the deleted files. So now I have a bunch of reconstructed .dbf files and such, but I don't know how to access them. Any better way to retrieve the data I regretted deleting?

I just used Migration Assistant to move my files from my iMac to my new Macbook Pro. I didn't know about the Filevault problem so when I tried logging in, I got the error message and I am unable to login to my account (the only one on the computer). The support page says to make a root user, but how can I do that when I can't even log in to my account. I dont have a disc copy of Lion I can use to start up with, only a copy of 10.6.
