largest SSD hard drives

Are you looking for the largest SSDs to boost your computer’s storage space? Check our list of the 3 largest SSD devices you can buy, and where to get them from.

Solid State Drives, commonly known as SSD, are a form of computer storage that is used today as an alternative to traditional and hybrid hard drives.

An SSD uses semiconductors in its construction, instead of magnetic media like other hard drives, and has memory chips that enable it to retain volumes of information, with or without power.

What differentiates SSD from traditional hard drives and USB flash drives, however, is their form, and capacity.

The latter, USB flash drives, are designed for external use, while SSDs are designed to sit internally within the computer, instead of using an external hard drive.

At first glance, SSDs resemble the usual external hard drive, but its form is designed to ensure it fits and sits properly within the laptop so that you don’t have to get an external hard drive.

This form is made possible by the SATA interface, which allows it to be placed into a PC in the same way you connect a hard drive.

Today, PC users prefer to use SSDs owing to the immense benefits they derive from them. Some of the benefits of SSD devices include:

  • High-performance storage
  • Higher data transfer rates because the SSD reads data instantly without spinning up the drive platter, or moving drive heads
  • Consume less energy/less power
  • A computer with a SSD is much snappier in launching apps and programs, and it also boots faster
  • High levels of reliability, because it has no moving parts and most of the storage is in memory chips
  • Higher storage capacity compared to hard drives

The downside with SSDsis that they have a limited life span owing to the fixed number of write cycles available before its cells become redundant, and they’re also costly.

Users however believe this still gives the SSDs a longer span compared to the normal PC systems.

The cost is still much higher than that of traditional or hybrid hard drives with similar storage capacity because it is pegged on the capacity of the SSDs, so the higher the capacity, the more you’ll have to pay for it.

Before we let you in on the 6 largest SSDs you can buy, it’s important to understand the capacity issue so that you can make an informed decision over which one to buy, vis-à-vis your PC or laptop.

A typical SSD ranges between 64 GB and 4 TB, and this in turn impacts on the drive’s performance, such that two different drives with different capacities will not have the same levels of performance.

As you look through our top picks for the largest SSDs, be sure to check the speed specifications and capacity level so that you can gauge the impact on overall performance.

  • In my experience I buy the drives which have a 5 year warranty which should all but guarantee that you will be able to use the drive for 5 years at least. I do not see high failure rates and have them in my workstations all over the facility in which I work. We have Windows machines and you do have to enable TRIM otherwise the drives will fail sooner rather than later.

  • What about the largest EXTERNAL SSD? I mean SSD and external (portable or not). NOT mechanical rotational hard dusks (HD).

  • you got that exactly right Ghostman, doesnt quite make the grade with a lead on like that just to draw you in, and dont give what has been promised, bate and switch i think they call it? not good at all, or just someone made a mistake, human error i can live with. Being dishonest i would rather not, dont get but a c+ for this as a grade, room for improvement i would say.

  • I came here looking for SSD reviews….three of the five are regular spinning HDDs. You should really proof this work before hand, or change the title.
