Quantum

Quantum was once an old and well-known hard disk manufacturer. They also led the introduction of many hard disk technologies in history, such as UDMA66, which is Quantum and Intel and several other companies jointly released it. Since Quantum focuses on the DIY market, the quality of its products is quite good, and its stability is very good under non-standard FSB conditions. It is very suitable for overclocking, but relatively speaking, the price is the highest among brands with the same specifications. Because of this, its products have always had a good reputation in the domestic market. However, even such a large company fell to the point of being acquired by Maxtor. The competition in the IT industry is so fierce.

The introduction to Quantum hard drives here is limited to the company's original independent products. Naming format of Quantum hard drive model:

QM + hard drive size + capacity + sales area + series identification + interface type

QM Quantum company identifier;

Hard drive size, consisting of 1 character,

2 represents 2.5-inch hard drive specification,

3 represents 3.5-inch hard drive specification,

5 represents 5.25-inch Hard drive specifications,

P stands for Performance,

L stands for low-cost technology;

Capacity, consisting of 3-5 characters, indicates the standard capacity of the hard drive ;

Sales area, represented by one character, R represents North America, B represents global sales;

Series logo, composed of 2 characters, its meaning and Chinese name and related See the table below for information.

The hard disk capacity represents the total capacity of the hard disk. , 1080 refers to the capacity of 1.08GB (i.e. the unit is MB). The small capacity hard drive products of the third generation of Fireball and its previous products are in MB, while the capacity of the hard drive after the third generation of Fireball is in GB, and 8.4 refers to its capacity. Capacity 8.4GB (that is, the unit is

GB).

The Fireball series is 5400RPM, while the high-energy Fireball series is 7200RPM. Both series of products are desktop-level hard drive products. Although the Bigfoot and Corsair series hard drives are also desktop-level hard drives, they have been phased out because they are early products. Of course, you may still see this large-sized Bigfoot hard drive on the computers of some old users. Among them, the Atlas series is a high-end product, which is mainly used on workstations and servers for high-end applications.

The model number of Quantum hard drive is usually found in the bar mark on the drive body and can be found on the outer drive cover near the hard drive interface.

The model label of a Quantum hard drive is usually located on the outer cover of the hard drive near the hard drive interface. It is also often located on the data cable sheath (circuit board side) of the hard drive. Its shape is similar to a barcode.

Interface types include the following:

A = ATA (IDE), that is, IDE interface

S = SCSI, 50-pin SCSI

W = SCSI Wide, 68-pin Ultra Wide SCSI

D = SCSI Wide, 68-pin Ultra Wide SCSI(HVD)

L = SCSI Wide, 68-pin Ultra Wide SCSI , Low Voltage Differential (low voltage differential)

J = SCSI SCA, 80-pin SCA SCSI

F = Fiber Channel, fiber channel

The following are listed on the market Most Quantum hard drive parameters on the website are for your reference when purchasing a hard drive:
