Bitlocker vs veracrypt3/28/2023 ![]() PS…who the hell encrypts data on an Atom anyway. It works on a lot more OS’s than BitLocker!!! Not nearly as nice as TrueCrypt…and TrueCrypt has proven itself to be a worthy tool…Bitlocker…ehh.ģ. ![]() It is just a simple encryption tool that will encrypt your drives and that’s about it. Microsoft has released so much rubbish in the last decade that when something as minimalistic as BitLocker finally works…people get excited. It’s funny how a persons standards can be lowered to the point that one actually thinks BitLocker is something special. Microsoft should have given Windows 7 away free…since it is really just what Vista was supposed to be. Multiboot, multipartitions, hidden partitions, on the fly encryption/decryption while maintaining full use of the drive. The encryption might have less options but the total drive management is much more versatile. But in defense of TrueCrypt I have to say that the difference is hardly noticeable running encryption on a netbook makes it slow whether BitLocker or TrueCrypt is used. So switching to TrueCrypt in order to increase performance is a bad idea. If you use the same algorithm in BitLocker and TrueCrypt, BitLocker is even faster by 14%. The default BitLocker algorithm (AES 128 bit with diffuser) is 12% faster. Here are the results:Īs you can see, TrueCrypt performs worse. For TrueCrypt, I chose only the fastest algorithm according to its built-in benchmark. For BitLocker, I chose three different encryption algorithms. To decide if it’s worth it to switch to TrueCrypt I ran some benchmarks on an Atom N260 Netbook. For some security gurus, open source is the only way to implement secure encryption because-by obfuscating code and not making it publicly available-the number of persons who can review and test the algorithm are limited. Nonetheless, TrueCrypt is very popular because it’s free and it is open source. TrueCrypt, a free application that was already discussed in a few posts, offers fewer options than BitLocker regarding centralized management. Neither option will increase the performance significantly, though, but maybe another encryption tool will. Installing more memory offers another boost in performance because the data is only encrypted when written to the hard disk. You can set a group policy to change the default encryption algorithm from 128 bit key with diffuser to AES 128 bit without diffuser, which lets you gain a little bit of performance at the expense of security. Enabling encryption further cripples their performance.Ī few options exist to help you gain a little bit of performance. Atom computers, however, just cope with a slim Windows Desktop, and as soon as more applications run at the same time the system feels slow. On common CPUs, you will barely notice a difference in how fast the computer deals with your daily work whether your hard disk is encrypted or not. Encryption isn't free, however, even with this tool-it needs CPU power. The Enterprise and Ultimate editions of Windows 7 offer a comfortable way to encrypt your hard disk and protect your data, called BitLocker.
