Toshiba debuts 60GB 1.8-inch mini-drives

updated 10:40 am EDT, Wed August 4, 2004

60GB drives for iPod?

when it unveiled the "4G" iPods.

Toshiba says the new drives set a new benchmark for areal density in the 1.8-inch HDD category at 93.5 gigabits per square inch, allowing Toshiba to fit 30GB of data onto a single 1.8-inch platter--an increase of 50 percent over current models.



"We are delighted to announce the world's highest capacity 1.8-inch HDD," said Amy Dalphy, manager, HDD business unit, Toshiba SDD. "We made improvements to push the capacity, increase shock resistance and to lower power consumption and noise. The resulting drives are perfect for integration in audio applications, such as mobile audio players, and mini-notebook PCs. We will continue to introduce high-capacity, small form factor HDD and contribute to making a reality of ubiquitous computing."



Toshiba says the it was able to achieve the higher densities by replacing the drives' Pico Sliders with Femto Sliders. Femto Sliders are attached to the drive's heads, and maintain the appropriate distance from the disk during read and write operations. The new Femto Sliders are 35 percent smaller and much lighter. Toshiba also made incremental advances in its thin-film technology for both the head and the platter.



The mini-drives are engineered to meet the stringent requirements for mobile devices such as MP3 players, handheld video players and handheld computers. Toshiba's 30GB (single platter) and 60GB (dual platter) HDDs offer an operating shock tolerance of 500G and non-operating shock tolerance of 1,500G through the employment of fluid dynamic bearing (FDB) motor technology. The drives' FDB motor also provides improved acoustics.



Toshiba said its new 1.8-inch drives also feature improvements in vibration resistance and power consumption. The drives are capable of withstanding 2G of vibration during operation. The power consumption of the new drives is approximately 20 percent lower on average than the company's current drive due to application of pulse width modulation (PWM) to control the disk rotation speed. The company was also able to use a DC-DC converter in the power unit to reduce power consumption.

    Raid

    Ok, so what I want to see is 8 of these in a 2.5" disk format as a RAID array that I can stuff into my powerbook..

    Hmm. lets see 480 GB, ultra high speed... in my powerbook..

    Wrong.

    No, what Apple said is that they had no plans in ANNOUNCING a 60 GB model. That's because there are no 60 GB mini-drives at this point yet. Once these 60 GB mini-drives start shipping & Apple can start integrating them in the iPod, then we will definitely see 60 GB iPods! Hopefully before Christmas, but by the sound of this article, it looks like we may not see them until MacWorld now.

    You guys are crazy!

    I'm gonna assume that the first poster is not serious, but just in case, I really doubt that drives are what are holding up the PowerBook G5. Heat, power consumption, and availability of the G5 processor is what's at play here.

    As far as the second poster...how do you expect eight 1.8" drives to take up the same space as a single 2.5" drive. It's going to require a lot more space than that, and a lot more than will fit in a PowerBook (G5 or otherwise).

    Mini Drive = Fan space

    Well, look on the bright side. If they move out the 4200 rpm drives from the current powerbooks and replace them with a mini drive, they will have so much space to put in a fan to cool the G5...... :-)

    These drives are 24mm x 32mm x 3.3 mm thick.
    A 2.5" drive is 70mm x 100 mm x at least 9.5 mm thick.

    Work it out, 4 drives wide = 96 mm x 2 drives tall = 64 mm. And the whole assembly is less than 1/3 the thickness of the smallest 2.5" drive.. Lots of space for the Raid logic..

    re: You guys are crazy!

    oops, never mind... was looking at the .85 " drives...

    We could still have two of the 1.8" drives in almost the same space as a 2.5" drive though.. At least that would be 120GB in a raid config... Still nothing to sniff at.. And if toshiba wanted to, I bet they could stack a 2x2 config in the same space..
