Samsung Announces 640GB 2.5-inch Hard Disk Drive

Samsung Electronics Co.,
Ltd., a world leader in digital consumer electronics and information
technology, today announced its new 640-Gigabyte (GB) 2.5-inch
Spinpoint M7 internal hard disk drive. The new 640GB hard drive, now
the top-density drive of the popular M7 family, has an areal density of
516-Gigabit per square inch for each 320GB platter, which is a 28
percent increase per platter over Samsung’s previous density-leading
500GB hard drive. Samsung’s new Spinpoint M7 model is designed for
high-end mobile computing applications requiring greater shock
resistance without a compromise in performance.

“With the addition of the new internal drive to the M7 series, our
customers will get the best viable combination of density, performance
and reliability that is essential for high-end notebooks and mobile
applications,” said C.H. Lee, vice president, Storage sales &
marketing, Samsung Electronics. “Samsung maximizes the density level of
its platters to enhance the reliability and stability of its internal
hard drives.”

Increasing the areal density of 516-Gigabit per square inch raises
the total drive capacity without adding additional platters. By
maximizing capacity without increasing mechanical parts, the
two-platter 640GB drive has lower power consumption levels and higher
operational stability compared to drives with a higher number of
platters.

The new M7 drive offers a shock resistance level of 400G (2ms) in
operation mode and 900G (1ms) when the power is off. An optimized
system-on-chip controller reduces the power consumption in both seek
and idle modes to the lowest level among comparable drives.

The Spinpoint M7 utilizes Samsung’s proprietary SilentSeek™ and
NoiseGuard™ technologies to minimize noise-levels during drive
operation. The halogen-free drive complies with the European Union’s
Directive on the Restriction of the Use of Certain Hazardous Substances
in Electrical and Electronic Equipment (RoHS).

The Spinpoint M7 series, which is available in 160-, 250-, 320-,
500- and 640-GB capacities, offers a rotational speed of 5400RPM, a
3.0Gbps SATA interface, Native Command Queuing and an 8MB cache memory.

Initial shipments will be available in Europe and the U.S. from mid
September, with worldwide availability starting from late September.
The 640GB Spinpoint M7 will begin shipping with a MSRP of $149.99.

  1. That much memory on a small card, I think they still make the 1 terabyte. I just do not understand why they are not about engaging with Solid State Disks, especially with laptops seems to me as an outcome.

  2. Because SSDs do not cost technically be interesting. A 640 GB SSD costs about the same, or a few percent more than this HDD? An SSD with a bit of performance (ie SLC chips) will cost you several hundred dollars quickly.
