What Factors Affect the Performance of an External Hard Disk?

What factors affect the performance of an external hard disk? You need to consider four important factors when buying an external hard drive: Partitioning, MTBF, Transfer rate, and Platter size. By following these tips, you will be better able to choose the best external hard disk price in Dubai for your needs. Read on to learn more! Ultimately, you can use your external hard drive for various purposes.

Partitioning affects the performance of the external hard disk:

The speed of data access depends on how the disk is partitioned. For example, if you have two partitions on the same external hard disk, you should expect about the same speed as if you had two separate physical drives. Partitioning helps defragmentation run faster. But it affects speed negatively if the disk is a physical drive. It has to move its head back and forth between the two areas simultaneously.


The MTBF of an external hard disk is a useful way to determine whether it will still be functioning after a couple of years. This number is derived from the average error rate of the disk over several weeks. It is not a warranty but a measure of the relative reliability of a family of mechanisms. The higher the MTBF, the more reliable it should be. Hard drives should be kept at a temperature of 86degF or below. The more frequent and higher the temperature, the less reliable it is. If the drive is stored in a cool, dry place, directed airflow of at least 150 linear feet per minute is recommended.

Transfer rate:

When it comes to data transfer speed, the transfer rate of an external hard disk is one of the most important factors to consider. Although the speed of data transfer may vary from one external hard disk to another, several factors can affect the rate of your external disk. Here are some factors to consider. Listed below are the most important factors to consider when comparing transfer rates.

Platter size:

The capacity of an external hard disk depends on the number of platters and their sizes. The more platters a drive has, the faster it will spin. This is why larger drives tend to perform better than their smaller counterparts. Platter size also influences access time. Larger drives have higher data densities and, therefore, longer access times. However, this does not mean that the bigger the drive, the faster it will be.
