SCOTTS VALLEY, Calif. — July 10, 2008 — Seagate (NYSE:STX) today unveiled
the industry’s first 1.5-terabyte desktop and half-terabyte notebook hard
drives to meet explosive worldwide demand for digital-content storage in
home and business environments.

The debut of the Barracuda 7200.11 1.5TB, the eleventh generation of
Seagate’s flagship drive for desktop PCs, marks the single largest capacity
hard drive jump in the more than half-century history of hard drives — a
half-terabyte increase from the previous highest capacity of 1TB, thanks to
the capacity-boosting power of perpendicular magnetic recording (PMR)

The Barracuda 7200.11 hard drive combines proven PMR technology, components
and expert manufacturing to provide 1.5TB of reliable storage for
mainstream desktop computers, workstations, desktop RAID, gaming and
high-end PCs, and USB/FireWire/eSATA external storage.

Seagate’s new 2.5-inch half-terabyte 5400- and 7200-rpm drives — Momentus
5400.6 and Momentus 7200.4 — deliver the best combination of capacity,
mobility and durability for mainstream and high-performance notebook
computers, external storage solutions, PCs and industrial applications
requiring small form factor.

Highlighting the global growth of digital content, Seagate expects to ship
its two billionth hard drive within the next five years. Earlier this year
Seagate shipped its one billionth hard drive since the company’s inception
nearly 30 years ago.

“Organizations and consumers of all kinds worldwide continue to create,
share and consume digital content at levels never before seen, giving rise
to new markets, new applications and demand for desktop and notebook
computers with unprecedented storage capacity, performance and
reliability,” said Michael Wingert, Seagate executive vice president and
general manager, Personal Compute Business. “Seagate is committed to
powering the next generation of computing today with the planet’s fastest,
highest-capacity and most reliable storage solutions.”

Momentus 5400.6 and Momentus 7200.4 hard drives are the fourth generation
of Seagate’s laptop family to use PMR. The Momentus 5400.6, a 5400-rpm
drive, combines a powerful Serial ATA 3Gb/second interface and capacities
ranging from 120GB to 500GB with an 8MB cache.

The Momentus 7200.4 hard drive, with its 7200-rpm spin speed and a Serial
ATA 3GB/second interface, delivers true desktop performance. The
power-efficient 7200-rpm drive maximizes battery life and comes in
capacities ranging from 250GB to 500GB with a 16MB cache.

Both Momentus drives are built tough enough to withstand up to 1,000 Gs of
non-operating shock and 350 Gs of operating shock to protect drive data,
making the drives ideal for systems that are subject to rough handling or
high levels of vibration. For added robustness in mobile environments, the
Momentus 5400.6 and 7200.4 are offered with G-Force Protection, a free-fall
sensor technology that helps prevent drive damage and data loss upon impact
if a laptop PC is dropped. The sensor works by detecting any changes in
acceleration equal to the force of gravity and parks the heads off the disc
to prevent contact with the platter in a free fall of as little as 8 inches
and within 3/10ths of a second.

Seagate’s new Momentus drives are lean on power consumption, allowing
notebook users to work longer between battery charges, and are virtually
inaudible thanks to Seagate’s innovative SoftSonic fluid-dynamic bearing
motors and QuietStep ramp load technology.

The Barracuda 7200.11 hard drive combines the capacity and speed required
for today’s most demanding desktop PC applications. The drive packs 1.5TB
on just four platters and its fast Serial ATA 3Gb/second interface delivers
an industry-leading sustained data rate of up to 120MB/second for fast
boot, application startup and file access. The 3.5-inch drive is also
offered in capacities of 1TB, 750GB, 640GB, 500GB, 320GB and 160GB with
cache options of 32MB and 16MB.

All Momentus and Barracuda drives are backed by Seagate’s leading five-year
warranty. You can find photos of these three new drives, and other Seagate
