The MG04 series delivers impressive capacity and offers Toshiba
persistent write cache technology
Toshiba Corporation’s (TOKYO:6502) Semiconductor & Storage
Products Company today announced the addition of 6TB[1] 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[2] 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[3]/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)[4], 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[5]) are also available.
Notes:[1] 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.[2] Read and write speed may vary depending on the host
device, read and write conditions and file size.[3] A mebibyte
(MiB) means 220, or 1,048,576 bytes.[4] 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.[5] 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.
