WD, a Western Digital company and world leader in storage and connected-life products, today announced it is shipping the world's first ultra-slim 2.5-inch, 5 mm hard drives and solid state hybrid drives (SSHD), which are designed for integration into the slimmest devices and space-constrained computing environments. With 500 GB of storage capacity and models with high performance-enabling solid state hybrid drive technology, this slim product line helps to address the tradeoffs system designers often make between capacity, physical size and performance.

"With the launch of our new WD Blue 5 mm ultra slim hard drives and our WD Black SSHD products, currently shipping to OEMs, WD is delivering to our customers a variety of solutions that maximize storage capacity and volumetric efficiency, as well as performance and system responsiveness, for consumers," said Matt Rutledge , vice president of WD's client computing business unit. "Our engineering team took a clean-sheet approach with 5 mm to deliver an ultra-thin hard drive that enables a world of possibilities and applications for mobile computing and beyond."



WD designed the new WD Blue and WD Black 5 mm drives to enable new levels of device portability. The new drives are aimed to increase internal storage capacity while enabling it to fit into smaller device slots. In addition, the slimmer and more portable the device, the more vulnerable the hard drive is to user-induced stress. To battle this, WD has designed key enablers to the 5 mm form factor:
  • Ultra-slim Form Factor - 5 mm height with compact connector offers system designers a greater degree of chassis design freedom. This ultra-slim form factor reduces weight by up to 36 percent compared with a standard 9.5 mm drive.
  • Best-in-class Acoustics and Shock - WD's best-in-class acoustics use technologies that reduce noise when the drive is active or idle. The WD Blue and WD Black 5 mm drives deliver unprecedented operation and non-operation shock specifications with 400 G and 1000G, respectively.
  • Edge Card Technology - WD designed the connector and board utilizing cell phone miniaturization technology to maximize the mechanical sway space in the hard drive and ensure shock performance.
  • Edge Card Connector - WD Blue 5 mm hard drives also feature the first application of a new small form factor SFF-8784 edge connector. This new connector receives power from and interfaces with the host I/O bus via the SATA interface connector SFF-8784.
  • StableTrac - The motor shaft is secured at both ends to reduce system-induced vibration and stabilize platters for accurate tracking during read and write operations which enables consistently higher performance.
  • Dual Stage Actuator - Leading-edge enterprise dual stage actuators provide two actuators that improve positional accuracy over the data track(s). The primary actuator provides coarse displacement using conventional electromagnetic actuator principles. The secondary actuator uses piezoelectric motion to fine tune the head positioning to a higher degree of accuracy.
Price and Availability
Shipping today to select industrial distributors and OEM customers in 500 GB capacities, WD Blue 2.5-inch 5 mm hard drives, (model: WD5000MPCK) has a Manufacturer's Suggested Retail Price (MSRP) of $89.00 USD. WD Blue 2.5-inch 5 mm hard drives are covered by a two-year limited warranty.

Seagate has 8GB on both their models (laptop and desktop version). I will jump on a leg here , and guess the competition will gravitate around that number as of current moment: http://www.seagate.com/files/www-co...docs/laptop-sshd-datasheet-1784-1-1302-us.pdf

What I don't like is they pair the flash to 5400rpm drive. Basically everything that is cached out of that flash runs on the slower speed. I don't understand why not pair it with 7200rpm?

I hope they add more NAND, something like 128GB or 256GB like how Apple do with latest iMac

Not entirely correct - the 750 GB Seagate Momentus XT variants are 16 GB NAND flash....

What model #? Everything from Seagate indicates only 8 GB on the 750 GB Momentus XT.
Sorry, You are right.
First gen was 4 gb and second gen is 8 gb

5400rpm drives have improved on speed a lot over the last few years and am betting that with the most accessed stuff cached on the flash that this will be somewhat quicker than comparable 7200rpm drives of the same size.
