A Little Background

An internal hard drive is the backbone and the memory storage of your computer system. Whether it is a laptop, a desktop or a notebook, you must have an internal hard drive because that is where the operating system will be put and installed onto. Whether you want to use Windows, Mac OS X, Linux and the like, you will need an internal hard drive.
Some people use an internal hard drive to upgrade their old internal hard drive, which is usually low at around 350 GB. Some people upgrade it up to 500 GB or 1 TB (terabyte) of disk space and then partition it so that they can use one side for the programs and the other side for the videos, music, photos and other media and other files. If they are not content then they can also use an external hard drive, some DVDs and CDs for backup as well as a USB flash drive. There are many kinds of backup systems today and all you need to do is to spend money for them so that you will be able to keep your files safe should a virus or a system failure or unexpected thing happen to your computer system.
Disk space is very important when it comes to big programs such as video editors, digital audio workstations, photo editors and the like. It is also highly important when it comes to playing video games, especially if you will use the PC mainly for gaming and such. Nothing gets you frustrated more than running out of disk space, whether it is on your PC or MacBook pro or any other system. Running out of disk space prompts you to move your files elsewhere and this can be very frustrating if you have programs that are not portable and cannot be moved thus. This is why you need a bigger capacity hard drive in your internal memory and system so that you will be able to upgrade to a better machine to keep all of your important files and also provide you with enough memory and CPU usage for your software.
Another great use of an internal hard drive is for RAID and 8-bay systems at home or on your business or as a server system in your local home or establishment. Having reliable internal hard drives in any situation makes your system reliable, especially if you are maintaining servers, whether it is just a gaming server or a business server for your clients and customers. Having reliability for your internal hard drive is important and this is why you need to pick out the best internal hard drive out there for your needs.

How We Picked

We picked the best internal hard drive based from the following:
Capacity or size – this refers to the capacity of any internal hard drive in gigabytes or terabytes. Most internal hard drives are 1 terabyte in size with the most common ones being 500 GB in size. Usually, if you purchase a laptop or a desktop computer, it already comes with 500 GB or similar capacity and you just need to upgrade it if you wish. The capacity of the internal hard drive is important if you want to put a lot of files in it. To do so and to maximize the drive’s full potential and capacity, you should have it partitioned at first format and boot.
Form factor – this refers to how slim the hard drive is and if it will fit your current system. Most hard drives are at a 3.5-inch form factor while some newer ones have a form factor of 2.5 inches which is slimmer. This is a good factor to consider when it comes to handling and lightweight features.
Rotation speed – this refers to how fast the magnetic disk spins within the internal hard drive and this can affect the storage capability and the data transfer rate of the internal hard drive. Usually, internal hard drives with higher RPM of rotational speed are much more preferred than the ones with lower RPMs.
Connection interface – a majority of internal hard drives today use SATA for connecting to your hard drive. You will less likely find rare PATA or IDE interfaces for an internal hard drive because that is a thing of the past. You will also less likely to find an internal hard drive that connects via USB port because it is meant to be inside your CPU or laptop. Usually, it connects via SATA3 connection, allowing for the fastest data access and transfer to and from your unit.
Transfer speed – most internal hard drives have a usual transfer speed of 6 gigabytes per second but they can also accommodate those with 3 gigabytes per second when it comes to backward compatibility.
Memory cache – this is expressed in MB or megabytes and is usually 64 MB or 32 MB, which also usually defines whether a system is 32-bit or 64-bit as an operating system. Of course, 64-bit systems are faster and much more time-efficient that 32-bit systems.
Compatibility – this one depends on where you want to use it. Most people who purchase internal hard drives use it for RAID systems and the like.

Other Frequently Asked Questions

Q: What are the things you need to consider when choosing the best internal hard drive?
A: According to PC Mag , make sure it is the amount of space you need, such as 1 TB or 2 TB depending on your usage. 1 TB or lower is fine for Windows 7 and storing basic documents and the like and 4 TB and above are ideal for video editors, gamers and the like. Since internal hard drives live inside your system, they consume energy so you should go for a space saving and energy efficient internal hard drive.
Most internal hard drives are Serial ATA or SATA so chances are they can support most systems from 3 GB per second up to 6 GB per second. If you have an old computer system then you should go for a PATA or IDE (Parallel ATA) which can be slower and larger than most SATA disks today. The form factor is also important when deciding for the best internal hard drive. Most hard drives for desktops have a form factor of 3.5 inches and some are slimmer at only 2.5 inches. If you have a RAID system in your home or business setting, you should also consider its operational value.

Q: What are the different types of hard drive connections for an internal hard drive?
A: According to Seagate , the most common internal hard drive connection is the SATA which gives you a high file transfer rate and is a standard among most computer systems. The eSATA is like the SATA but mostly adheres to the speed of your computer system while the FireWire connection is ideal for transferring video files due to being 800 times faster than standard USB connection systems. The USB connection is the most common of all and can be used by most hard drives with lower capacity.

Q: What is the difference between an SSD or Solid State Drive and an HDD or Hard Disk Drive?
A: According to PC Mag , an HDD or hard disk drive is the traditional hard drive with a magnetic coating. It allows you to access your data as the platters spin, similar to how a turntable plays music when the long-playing record spins. The SSD or solid state drive is almost like the HDD except that it uses flash memory chips instead of the spinning magnetic coating. The SSD retains the data even without power and are said to have better reliability when it comes to storing memory. This is the same technology for USB flash thumb drives, but it is significantly better and more reliable.

Q: What are the tips you need to consider when maintaining your internal hard drive?
A: According to Overstock , you must protect your electronics using surge protectors. When there is a power outage, do not leave your computer on or your laptop plugged to an outlet to avoid power surges. You should always back up your data so that you will not regret it later. If you use the internal hard drive as a server then it should be regularly backed up. The installation of the hard drive must be proper to prevent clicking and excessive noise. Make sure you clean up your CPU so that the dust build up will not have a chance to clog up your hard drive and other components of your CPU or computer and cause heating. You can also burn onto DVDs and CDs or use an external hard drive to back up everything.
