I've tried and used Disk Utility to create an encrypted image, so I can store data in it securely. However, when I tried to write files to this image, the write operation was too slow (to write ~50 GB of data, it would take 1 day as estimated).

My question: is there a robust alternative that allows creating an encrypted space in the hard disk to store data with fast read/write operations?

Device :

Apple MacBook Pro (15-inch, Mid 2012)

  • Processor : 2.6 GHz Intel Core i7

  • Memory : 8 GB 1600 MHz DDR3

  • Hard drive : APPLE HDD HTS547575A9E384

    • Rotational Rate: 5400
    • Partition Map Type: GPT (GUID Partition Table)
  • OS version : 10.12.1

I am transferring data to an encrypted image on the hard drive. Its encryption type is 128-bit AES.

Source of data

The external hard drive that I am transferring data from : StoreJet Transcend Media.

  • Partition Map Type : GPT (GUID Partition Table)
  • Encrypted. Encryption Type : AES-XTS

    USB 3 can do 640MB/s, but a 5400 drive probably at best 100MB/s. Additional factor would be how full the HD is & how fragmented. 50GB of free contiguous space would be unusual on a 4-year-old 750GB boot drive. – Tetsujin Dec 10 '16 at 10:52

    I'd suggest replacing your internal HDD with an SSD. This will not only speed up your data transfer rate but help speed up everything you do on the computer. – NoahL Dec 10 '16 at 15:40
