Encrypted with TrueCrypt, veraCrypt, DiskCryptor or any other will make read and write to be much more slower, the best i got is arrond 100MiB/s (one tenth of non encrypted), so encryption makes it to be ten times slower.I don’t know what the drive’s original speed was though.ĭoes this mean that an encrypted partition is slower than an encryption that’s not encrypted, even after mounting it? Does it actually encrypt the newly copied files while it’s copying, slowing down the copying operation massively?Īnswer: My tests with a USB 3.1 Gen 2 Type C hard disk (able to write at 10Gib/s, aka a little more than 1GiB/s) is: The other drive’s speed, after encryption, was much lower, maybe 10 MB/s. I just copied a file over to it and the speed was about 100 MB/s. I did the same thing with a similar drive. I want to create an encrypted partition on it with VeraCrypt.
Question: I just got a new external hard drive.
