【 Weak current College 】 how to recognize the hard drive model code

Now available in a wide range of hard drives, each manufacturer for the respective product number. Generally speaking, the number of the hard disk to determine the technical parameters of the hard disk, such as brand and product family, size, speed, capacity, support of interface types.

Seven: Hitachi hard drive model

Hitachi (Hitachi) successor IBM hard drive's advanced technology

Since Hitachi combines IBM hard disk sectors, Hitachi will inherit the IBM hard drive technology. We all know that IBM is the biggest global memory, history of many groundbreaking memory technology is for IBM, as the most typical of modern hard disk (i.e., "Wynn" hard drive) in embryonic form was developed by IBM Corporation, and of course later widely used "MR (reluctance)", "GMR (giant magneto resistance)" head and its famous "PixieDust (fairy dust)" technology is developed by the IBM Corporation. Although at present in the domestic market performance in general but its powerful background and strength, who also can not be ignored.

Key tricks Hitachi 180GXP series model identification method

Hitachi hard drives have 180GXP and 7K250 two series, so to distinguish its number is more complex. 180GXP series follows the IBM hard disk number. Its recognition as: "IC + disks size + hard drive height + capacity + interface type + series model + speed + cache capacity"

Simple representation: IC "X, XXX XX, XX, XX,, XX-X", its hard disk serial number can be divided into seven parts.

"IC" represents IBM's products.

The first part of the two "X" represents the shape and size of your hard disk. "35" said 3.5 (88.9 mm), "25" said 2.5 (63.5 mm) hard drive products.

The second part of the "X" represents the height of the hard disk. "L" stands for 1-inch (25.4 mm), the "T" 0.49 (12.5 mm), "N" represents 0.37 (9.5 mm) hard drive products.

The third part of the three "X" represents the hard drive capacity, the unit is GB. If the "180" is expressedThe hard drive's capacity for 180GB, "080" is 80GB.

The fourth part of the two "X" represents the hard drive interface type.

"AV" expressed as ATA interface

"UW" represents the interface for Ultra160SCSI68-pinWide
The "UC" represents the interface for Ultra160SCSI80-pinSCA
"XW" represents the interface for Ultra320SCSI68-pinWide
"XC" represents the interface for Ultra320SCSI80-pinSCA
"F2" expressed as FC-AL-2 (2Gbit) interface

The fifth part of the two "X" indicates that the hard drive product series models. The "ER," said Deskstar60GXP series, "VA", "said Deskstar120GXP series V2" said Deskstar180GXP series.

The sixth part of the two "X" indicates that the hard disk rotational speed, RPM/min is the unit. His "04" represented as a 4200RPM/min, "05" is expressed as a 5400RPM/min, "07" represented as a 7200RPM/min, "10" represents as 10000RPM/min, "15" is expressed as 15000RPM/min.

The seventh part of the "X" indicates the capacity of the hard disk cache, from Deskstar180GXP. "0" indicates that is 2 MB cache, "1" represents as 8MB cache. Which use a disc of 60GB product cache is 2 MB, uses two platters of 80GB and 120GB product cache has two 2MB and 8MB, use three disc of 180GB product cache are purchased for 8MB, should pay attention to distinguish.


IC35L180AVV207-1 "," this code as an example, we can know the hard drive number is IBM company 3.5, high 1 inch hard drive, its total capacity as 60GB, using UltraATA interface, a series of products, Deskstar180GXP speed is a 7200RPM/min, with 8 MB of cache.

Key tricks Hitachi 7K250 series model identification method

Hitachi 7K250 series is the introduction of new Deskstar180GXP. Its performance than previous products better, but the hard drive number has changed, causing confusion. Here we have to look at Hitachi 7K250 series hard drive number.

7K250 series number dimensioning as "HDS + speed + series of maximum capacity + the product capacity + product series code + hard drive height + interface type + cache".

Simple is expressed as: HDS "XX XX, XX,, X, X, X, X, XX," hard disk number can also be divided into eight parts.

"HDS" expressed as Hitachi (HITACHI) Deskstar series hard drive products.

The first part of the two "X" represents the hard disk speed. If the callout is "42", "54", "72", "10"; "15", etc, then this drive's speed 4200RPM/min respectively, 5400RPM/min, 7200RPM/min, 10000RPM/min, 15000RPM/min.

The second part of the two "X" represents the product range of the maximum capacity, measured in GB. "25" means the maximum capacity of 250GB.

The third part of the two "X" is represented as a hard drive capacity, the unit has a GB or 10GB. For example, "80", "says 80GB 25" means 250GB.

The fourth part of the "X" represents the hard disk of algebra. Now all 7K250 series is the letter "V".

The fifth part of the "X" represents the height of the hard disk. Here and the IBM number is the same.

The sixth part of the two "X" represents the interface type of the hard disk, the "AT" and "ST". Its behalf for UltraATA100 interface and SerialATA150 interface.

The seventh part of the "X" indicates the capacity of the hard disk cache, there is a number "2" and "8". Their behalf is 2 MB cache and hard drive product 8MB cache.

Eighth part of the "X" is the hard disk retention values, being a number "0".

The Hitachi 7K250 series "HDS722525VLAT80" hard disk number for example, we can know it belongs to a 7200RPM/min, maximum capacity 250GB and total capacity of 250 GB hard drive, 1 inch, is UltraATA100 interface and owns 8MB cache.
