IBM ships 146Gbytes drive

IBM has announced it has shipped 5,000 units of its Ultrastar 146Z10 hard drive.

IBM has announced it has shipped 5,000 units of its Ultrastar 146Z10 hard drive.

The Ultrastar 146Z10 is the company's third generation of 10,000 rpm disc and is equipped with a technology that IBM claimed damped the vibration caused my a multitude of discs operating simultaneously.

"Having multiple discs in a rack running simultaneously affects the reading and writing of the drive," said Bill Healy, IBM vice-president of marketing. "Our technology improves reliability and quality."

Healy added that the vibration dampening is done in software algorithms and microcode, and it is a feature IBM believed was unique to the Ultrastar 146Z10.

"Other vendors have toyed with the idea [of vibration dampening techniques], but not commercialised," explained Healy. "[They've done] only lab demonstrations."

In addition to its focus on reliability and quality, IBM has also doubled the capacity of the disc from its last-generation drive, which had a maximum capacity of 72Gbytes.

The latest drive has a capacity of 146Gbytes and will compete with drives of the same capacity announced already by IBM's competitors. IBM believes they are the first to have shipped in high volume.

"We completed testing before announcing the product and wanted to wait until we were shipping," said Healy. "It is a marketing strategy."

This year is IBM's 50th anniversary of shipping hard drives for this series of product, explained Healy. Like those drives before it, the Ultrastar 146Z10 has been developed to work in data centres, but may also find its way in Web server-like products from companies such as Dell.

The company says the disc is in evaluation with its partners and expects to see third-party products shipping with the Ultrastar 146Z10 in September or October.
