What are hard disks and why do we need them?

Hard disk is the storage part inside a computer. Essentially, it is called a hard disk drive (HDD) because a disk inside the drive stores all the data – from excel files, programs, documents, applications to movies, songs, photos, recordings, and everything else. Arguably, without a hard disk drive, it is very difficult to save anything on a computer. 


While there are several types of flash drives, they could not replace the traditional hard drives until the arrival of SSDs.

Different types of hard disks

To know which hard disk is best, one must know how many types of hard disks there in the market are. The hard disk drives are primarily classified based on their configuration and storing process. There are mainly three types of hard disk drives available – SATA Drives, SSD Drives, and NVMe Drives.


SATA Drive-

Hard drives connected through SATA or Serial Advanced Technology Attachment ports are called SATA drives. Most of the traditional hard disk drives are SATA drives. This is probably the most popular type of hard disk drive.


Features of SATA

SATA hard drives are cost-effective and can have massive storage capacity compared to other hard drives. A SATA hard disk can store between 500GB to 20TB of data. SATA drives with higher storage capacity have multiple spinning disks inside. Therefore, these types of HDDs are chunkier than SSDs or NVMe drives. Since the SATA ports are inexpensive (depending upon their storage capacity), all SATA HDDs are the best external hard disks.


 SSD Hard Drives –

Solid State Drives or SSDs are newer versions of SATA drives. There is a major mechanical difference between a SATA drive and an SSD drive – SSDs don’t have a rotating disk or plate inside the drive. Moreover, SSD hard drives do not have as many moving parts as conventional SATA drives. As a result, SSD drives have a longer life span.


Features of SSD

Compared to SATA drives, SSD drives have significantly faster data transfer speed. However, they have compact housing and have less storage capacity. Because of their design, SSDs are an ideal storage option for laptops. SSDs have gained popularity over the years. Despite the spike in their supply, the SSDs still cost two to four times higher than the SATA Drives.


NVMe Hard Drives  

NVMe Hard drives are the latest invention in storage devices, and these slots are the fastest among all the storage drives. NVMe drive has a 32Gb/s interface rate, higher than the 500 Mb/s read&write speed of an SSD. For comparison, traditional SATA hard disk drives have a 120Mb/s interface speed.

Another reason behind NVMe drives achieving such crazy speed is that they do not connect through any SATA or USB port. They are connected straight to the PCIe slot, which is meant for graphics card integration because of their high-speed data transfer capabilities.


Features of NVMe

Gamers like to use NVMe storage because of their high-speed data transfer capabilities. Besides having a 32Gb/s interface rate, it has a 3.9Gb/s throughput speed. However, there are some cons of NVMe drives –

  • They are very expensive
  • Booting the computer from NVMe is difficult
  • NVMe storage connects through PCIe slot, and therefore, one can not use it in laptops
  • The user may need to replace the motherboard to get the full benefit of an NVMe storage drive

Specifications to Consider while making a purchase


At this point, we know what the main types of hard disk drives are available in the market. We know what different features they have and their respective pros and cons. While this information is primarily on internal hard disks, they prove equally important while shopping for the best external hard disk.


If you are planning to make a bulk purchase of external hard disks, consider the following aspects –


Storage Capacity –

All the types of HDDs mentioned in this article have varied storage capacities. For buyers seeking higher storage capacity, conventional HDDs shall be the best external hard disk for that purpose. They are relatively cheaper and offer a maximum storage space (highest in the segment). The Seagate One Touch 2TB External HDD is an excellent choice for it has a decent transfer speed yet costs a lot lower than a 2TB SSD.


Transfer Needs –

 If you intend to assemble computers for work that requires a high-speed data transfer rate, you should focus on SSDs or NVMe drives. As we mentioned earlier, NVMe drives have an industry-leading interface rate of up to 32Gb/s. However, SSDs are a more practical and feasible choice for many reasons. They are a lot faster than the SATA hard disks and easier to install than NVMe drives. WD 2TB My Portable External Hard Drive is, for example, a 2TB storage drive that connects using USB 3.0.


 Cache Space –

 When two components inside a computer transfer data, they use a buffer or cache memory. Generally, modern-day HDDs have 8MB to 256MB cache memory, but you should always buy the one offering a higher cache. Higher the cache memory, smoother gets the data transfer.


Access Time –

Some may emphasize access time, but all of the modern-day hard disks have marginal differences. Therefore, access time is not a decisive parameter in choosing the best external hard disks.


Failure Rate –

 Like any other internal component inside a computer, hard disks may also fail after some period. They have moving parts inside the drive that face wear and tear. Some HDDs fail after a year, while others keep going for several years. The key is to choose the best external hard disk from popular brands.


Amazon Business, for example, only lists premium quality external hard disks from industry-leading brands like Seagate, Toshiba, Dell, Samsung, and many others.


Compatibility –

 Device compatibility should always be on the buyer’s checklist while searching for the best external hard disk. The best external hard drive is the one that supports Mac, Windows, and Linux operating systems.


External Hard Drives Vs Internal Hard Drives


As the names suggest, internal hard drives are internal components of a computer. In contrast, external hard drives are portable alternatives, and that’s the only fundamental difference between these two types. Now, if someone wants to evaluate the advantages and disadvantages of internal and external hard drives, here is a quick look at it.


  • Internal hard drives,
  •  Offer higher storage option
  • Constantly connected to your PC or laptop
  • Very cost-effective
  • External hard drives,
  •  Portability is a big plus point
  •  Easy connectivity through USB ports
  • Good storage capacity on offer
  •  Compatibility across devices enhance further enhances portability


Hard Drives for Gaming


The reason behind anyone purchasing an external hard drive is portability or the shortage of in-device storage. Average users use external hard drives to store documents, files, videos, images, tracks, and so on. While accessing any of such files is simple, the story changes when it comes to accessing heavy applications or games. In that case, gamers need a high-speed data transfer rate from their external hard drives.


For gaming, it’s recommended to purchase external SSDs or NVMe drives because they have much higher data transfer speed than conventional SATA drives.

  • First, we need to know the purpose behind buying an external hard drive. For example, if you need a big storage capacity, you can go for a SATA hard disk and save some money. Otherwise, you may need to spend some extra to purchase external SSDs that may offer less storage space but high data transfer speed.

  • There might be a difference of opinion on the internet, but, broadly speaking, hard disks and hard drives both mean storage devices in a computer or laptop. The apparent fundamental difference could be the construction of hard disk drives.

    The term hard disk might have been originated to address the fact that traditional hard disk drives have a spinning disk inside.

  • Hard disk is the storage device inside a computer. Essentially, it stores data. All of your movies, songs, files, documents, everything is stored inside a hard disk.


  • Yes. When the storage space runs out, the operating system itself may struggle to perform properly. Many applications may fail or shut down abnormally because of a lack of space. They cannot save new data and crash.

  • There are mainly three types of hard disk drives available: SATA Drives, SSD Drives, and NVMe Drives.
