Which Statement Regarding The Selection Of A Hard Drive Is Accurate?

The magnetic drives will have a larger capacity when compared with solid-state drives. Today, let us discuss magnetic drives and the difference between magnetic and solid-state drives. The magnetic drive which usually called the hard disk or a hard drive. The floppy disks are also called magnetic disks. Let us know how a magnetic drive looks like, it has a spindle to which we can attach the platters. All the platters are attached to the spindle and rotate at the same speed. The below figure represents the structure of how the magnetic drive looks like.

The single platter has a surface that is covered with magnetic material on one side and the other.

We normally have the three platters that actually have the six surfaces. The data bits can be present on all the surfaces. We can access this data by having a simple magnetic head that is attached to an arm and another one at the lower surface.

All of these heads are attached to a head assembly that can move all the heads in unison. All the heads will be in the same position as the different platters. We move all of these heads at the same time. Each head can able to access its own surface and all of this will be going with the same distance in the spindle. This is called the track. All of the tracks will be at the same distance from the spindle that forms a shape called the cylinder. The cylinder will simple consists of one track from each surface and the tracks in the cylinders are the one can be accessed by the different heads at the same time.

The data along the one track is divided into the form of different sectors, and each sector will be the smallest unit that we can actually read.

Now, let us know what actually the solid-state drives are, it is like a data storage drive that can store the information in the computer. The solid-state drive can use flash memory in order to store the data when the system gets turned off. The solid-state drive has the same process as the traditional hard drives in accessing the data. This solid-state drive has common interfaces which are compatible with hardware drives. This solid-state drive uses some of the interfaces like m.2 and the SATA. Solid-state drives are quite different from traditional and mechanical drives. We can access the data much quicker in the solid-state drives and has a lower latency in it.

These solid-state drives are mostly used in the IBM think pads, and in the SanDisk corporation. The speed and the performance of the solid-state drive are much more than the hard disk drive. The SSD’s have speeds in the range of microseconds and the usually read and write speed is in the range of 400 to 500 Mbps. We can also use it as the sequential read and write with the speed of gigabytes per second.
