BitLocker encrypted system drive for everyday use and gaming?

So, newer processors like i7-3840QM have hardware AES encrypting on the fly that (i have read somewhere) is faster than a SSD drive can read and write.

Do you think that if i encrypt my system drive with BitLocker i won't feel any noticeable decrease in overall speed? Truecrypt does decrease it pretty much i would say.

 

In fact, older SandyBridge CPUs like mine also have AES hardware acceleration. It's not new.
I'v been using Truecrypt for a while with an SSD and the speed difference is negligible. You do have to use AES-NI though.

 

I would be more interested in hearing from guys who have 2012 year's Clevos with fast CPUs and BitLocker encrypted SSDs

 

It's the same either way. AES-NI is hardware accelerated, so bitlocker and truecrpyt would have the same performance.
Also, if it works well in last gen CPUs, it will work well in current ones.

 

One guy on one forum has said the following:
Trim and garbage-collector does not work on the encrypted drive. Having lots of unused space on the drive will however make the decline in performance take more time.

Is that true?

Depends on the encryption. Some do full partition encryption, meaning even blank data, others only do the actual used data.

As for performance itself, the speed would be the same regardless of what encryption software used so long as you used AES.

Now one thing you need to take into account that DOES impact speed is that if using SSD, SOME of them work based on using compression to get the speed they advertise, so Sandforce for example does. When you encrypt the drive it can do 0 compression thus speeds will be slower.

Some newer drives, such as Vertex 4 OCZ for example does NOT rely on compression to obtain its speeds and thus encryption would have a MUCH less impact vs say the Vertex 3 which uses Sandfoce...

So IF you are going to encrypt and your drive is SSD you need to take two things into consideration...

Does your drive use compression to obtain it's speeds (All Sandforce based ones do from my understanding)
How does the encryption software work... If only does actual data and not blank space also TRIM will be fine...

I don't know what Bitlocker does off the top but I believe Truecrypt does everything, even blank space, however they have stated TrueCrypt - Free Open-Source Disk Encryption - Documentation - Trim Operation so that makes it sound like its fine...

Anyway, good luck on your journey getting better answers. Is a lot of misinformation posted due to a lot being unknown.

 

For now my latest knowledge says me not to encrypt the whole drive with OS and all not important files. Everything else could be used inside of TrueCrypt encrypted file container and KeePass

 

bitlocker has been hacked by people and they warned Microsoft but Microsoft does not care , so its useless
Security boffins unveil BitUnlocker • The Register
Microsoft downplays Black Hat BitLocker, TPM hack
Dislocker, a free tool to decrypt Bitlocker volumes | Hacker 10 – Security Hacker lol
So I would suggest to use trucrypt. also like the poster said above sandofrce based ssd are not very good . there reliability are not good . you should look for non-based sandoforce controller

 

That first link you posted will apply to just about any encryption software, including truecrypt so probably not a good source to use.

That said, I would still trust open source over MS any day
