How can I choose the best internal hard drive?

There are several methods to identify the best internal hard drive. In most cases, physical sizes and connection type are useful to narrow the available options. Once you have a smaller list, it controls capacity, search time and data transfer speed is often enough for most users. The size of their cache and the amount of noise they give sometimes helps make a final decision. There are two common types of internal hard drives: IDE (integrated power electronics) and SATA (serial advanced technological connection). Some motherboards have space for both, but most of them accept only one type of unit, so you have to find out what your motherboard can handle. Another is physical size - a typical desktop computer needs a 3.5 ”unit and the notebook requires a 2.5" unit. This is almost always the case, but there is a possibility that the system is different.

Many people buy a new internal hard drive for storage. As a result, capacity is often very important for many buyersm factor. Drive capacity is usually expressed as gigabytes (GB) and terabytes (TB). This printed size is non -formatted capacity; After formatting, the drive loses about 10% of its total space.

The internal hard disk has a quality called Seet Time. This is the time you need to find stored information. This time it is usually measured in milliseconds (MS) and you want this number as low as possible. Typical home units range from 9 and 12 ms, but rides with much higher and lower search times are available.

Data transfer speed is a speed at which an internal hard drive is able to send and receive information. Some units provide a specific transmission rate such as 3 GB/s, while others don't. If the unit does not specify the Fer transhex, then the speed of the drive, measured in the revolutions per minute (RPM), report a rough indication. The three most common RPM are 5 400, 7,200 and 10,000,Mž higher are better.

The size of the unit cache is the type of internal memory. This will store information that makes the unit to be needed and orders that are currently unable to make. Since this information is kept in memory rather than recorded on the unit, it is much faster to load. The larger the cache, the more information can be stored. The cache size is measured in megabytes (MB) and the higher the better.

The last common factor when selecting a hard disk is noise. Voice noise is measured in sound decibels (DBA) and you want the number as low as possible. Although this factor is often not important to many users, some systems require very quiet components.
