Data Security Option
Travelstar Z7K320 is the fourth generation to feature optional Bulk Data Encryption (BDE)
for hard-drive-level data security. With BDE, the data is scrambled using a key as it is written
to the disk, then descrambled with the key as it is retrieved, giving users the highest level
of data protection available. It also speeds and simplifies the drive re-deployment process.
By deleting the encryption key, the data on the drive is rendered unreadable, thereby
eliminating the need for time-consuming
