Keeping your critical data safe

Your data is critical so don't risk losing it. Toshiba's proprietary technologies have been developed to add security and assurance to the enterprise user. With Persistent Write Cache Technology your data is safe in the event of an interruption in power supply during a write to the hard disk. Data is saved in the large flash-based cache and written to the disk when power is restored.

Technology options for peace of mind

Keeping your data secure is made simpler by choosing a Self Enrypting Drive (SED) from Toshiba. This feature option uses cryptography to encrypt data as it is written on the hard disk drive. Additonally, if you choose a hard drive with Sanitize Instant Erase (SIE) technology, all data can be erased in an instant without the need for overwriting the drive for hours.
