    PC Card ExpressCard. Data is accessed in a random-access manner, meaning that individual blocks of data can be stored or retrieved in any order rather than sequentially. With Class 0 encryption, you need to install it internally into another system that knows how to prompt for an HDD password, whereas with software encryption you can connect the drive through an external enclosure and access it just fine that way, no "hardware-level unlock" support required.

    The newer speeds may require higher power consumption for supporting chips, though improved process technologies and power management techniques may mitigate this.

    When the computer is next powered on, the PBA should ask for your password; then unlock the drive and chain-load the decrypted OS. In fact, in drives featuring full-disk encryption, data is always encrypted with the data encryption key when stored to disk, even if there is no password set e.

    Retrieved 4 December Hardware-based encryption when built into the drive or within the drive enclosure is notably transparent to the user. When shopping for an SSD one must realize that, as the price point goes up, so does the quality of the NAND flash memory, the flash controller and so on, although probably not linearly.
