The most important steps in hard drive development
1956
The first hard disk weighs 500 kg
IBM launches the very first
hard drive, called the IBM
350 (5 MB, 24 inches, 600
ms access time 1,200 rpm,
500 kg, 10 kW). The drive is
rented out for approx 5,000
dollars per month.
1963
Open disk pack The IBM 1311 was
announced on 11th October. It could store
2 million characters on an interchangeable disk
pack (IBM 1316). The disk packs were 4 inches tall,
weighed 4.5 kg each and used 6 14-inch disks with
10 writable surfaces.
1973
Winchester ‘73
IBM launches the “Winchester” project
with the objective of developing a disk
drive in which the rotating medium is
firmly fixed. The loading mechanism is
problematic—that is also why the name
is similar to that of the legendary rifle.
1979
The first 8-inch Winchester
In 1979, industrially manufactured
Winchester disks were introduced.
They were even heavier and
costlier, but the sales only
increased.
1980
The first 5.25-inch drive Seagate brings the ST506
into the market (6MB, 3,600 rpm, selling price:
$1,000).The model label ST506 was the name for
the interface for years.
1986
SCSI specification SCSI became one of
the first standardized I/O protocols for a
hard disk interface.
1989
IDE standardization Western Digital
standardized the Integrated Drive
Electronics protocol.
1997
Giant magnetoresistance First use of the giant
magnetoresistance effect discovered by Peter Grünberg.
IBM overcomes the 10 GB barrier with the DTTA-351680.
2004
Introduction of NC Q Seagate brought the
first SATA hard disk with Native Command Queuing
to the market.
2005
First hybrid drive Samsung created
the HMO8HHI, a 2.5-inch hybrid
disk made out of a magneticmechanical
component and an NAND flash
memory used asa quicker buffer.
2006
Perpendicular recording
The Momentus 5400.3, a 160 GB
large 2.5-inch hard disk from
Seagate used perpendicular
recording technology.
2007
Terabyte hard drive With the Deskstar
7K1000, Hitachi brought the
first 1 Terabyte hard drive to the
market.
