TOKYO--(BUSINESS WIRE)--Toshiba Corporation’s (TOKYO:6502) Semiconductor & Storage Products Company today announced the addition of 6TB SATA and SAS models to its MG04 series of 3.5-inch form factor enterprise capacity class of hard disk drives (HDD). New SAS interface models provide the benefits of 12Gbit/s transfer rate for 6TB, 5TB, 4TB and 2TB HDDs. Sample shipment will begin in CQ1 of 2015.
The new MG04 series 6TB models offer a 50 percent increase in max capacity from prior MG03 generation 4TB models and approximately 30 percent increase in sustained data rate (MG03xxx400x:165MiB/s, MG04xxx60Ex:205MiB/s). These new HDDs support both industry-standard 4K native and 512e Advanced Format sector technologies for optimum performance in the latest generation servers and storage systems as well as being suitable in legacy applications requiring 512 sector lengths using aligned-write environments.
Both the 6TB MG04ACA and MG04SCA 12Gbit/s models offer Toshiba persistent write cache technologies (PWC), designed to help protect against data loss in the event of sudden power loss. Model options supporting SAS and SATA commands to enable sanitize “instant” cryptographic erase (SIE) are also available.
 Definition of capacity: Toshiba defines a terabyte (TB) as 1,000,000,000,000 bytes. A computer operating system, however, reports storage capacity using powers of 2 for the definition of 1GB = 230 = 1,073,741,824 bytes and therefore shows less storage capacity. Available storage capacity (including examples of various media files) will vary based on file size, formatting, settings, software and operating system, such as Microsoft Operating System and/or pre-installed software applications, or media content. Actual formatted capacity may vary.
 Read and write speed may vary depending on the host device, read and write conditions and file size.
 A mebibyte (MiB) means 220, or 1,048,576 bytes.
 PWC with PLP (Power Loss Protection: see below) is a function to handle the write data that the drive reports "Normal completion" to the host but not being stored to hard disk media yet. The write data may be written to the commanded LBA on the hard disk media. The un-written data to hard disk media is stored to flash memory using back up power by PLP when the power supply to the drive suddenly is shut down. And, after PLP operation, it may be required more time to start up the drive than in case of normal shutdown. 1) PLP does not secure data in the mode of all the power shutdowns. When power supplies other than recommended procedure are intercepted, data might be lost. 2) In the power shutdown before it reports on the write completion, data not anticipated might be lost.
PLP (Power Loss Protection): PLP supports the recording of data in buffer memory to hard disk media utilizing back electromotive force along with media rotation inertia in case of sudden supply shut down.
 SIE: Sanitize Instant Erase. SIE is compatible with Sanitize Device Feature Set. Sanitize Device Feature Set is the standard prescribed by T10(SAS) and T13(SATA) committees of American National Standards Association (ANSI), which makes it possible to invalidate the data recorded on the magnetic disks at a blink.
