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.

Speed up your SSD performance with these great tools!

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.

What are the largest SSDs on the market?

1. Samsung PM1633a SSD

samsung16tb hard drive


This was the very first SSD to be announced and had maintained its position as the largest storage drive worldwide until Seagate unveiled it’s own 60 TB SSD.

It has a capacity of holding 16 TB of data and uses 3D NAND technology, which basically stores information vertically rather than horizontally (on a flat surface).

It boasts 1200 MB/s read, and 900 MB/s write speed performance, which makes it very ideal for managing volumes of data that require a large capacity to store.

This drive sells at an average price of $10,000, a figure that may be too expensive for consumers looking for storage for personal needs, but for enterprises, this is a steal.

If you don’t want to pay $10K for this device, you can get the 4TB version which costs less.


  • High read and write speeds
  • Large storage capacity


  • For personal use, it is expensive to buy, it costs around $10,000.
