Product Details

Capacity

4000 GB

Capacity

The amount of data that a hard disk can store. 2TB and 4TB are the golden ratio of cost and capacity. For simple use, 1TB is likely sufficient. For reference, a 1TB hard disk can hold approximately 250,000 photos taken with a 12MP camera or 250 movies.

Communication Protocol

SAS 3.0

Communication Protocol

Hard drives communicate with the computer through a protocol.

There are two protocols for HDD hard drives, SATA (for simple use) and SAS (high reliability for corporate use).

SAS 3.0

A modern connection standard with high reliability aimed at corporate use.

The motherboard should have a corresponding connection.

Performance

RPM

7200 rpm

RPM

The most important feature along with capacity is that the faster the rotation speed of a hard disk, the faster the access and storage of data it can provide.

7200

The most popular HDD hard drives, about 33% faster than 5400. Suitable for all uses such as installing programs and games. For installing the operating system, programs, and games, SSD are even faster and remain the best choice.

Cache size

256 MB

Cache size

Intermediate temporary memory between the disk and the computer, allowing the hard disk to provide faster and more immediate access to data. It does not have any particular benefit for the average user.
