10 Best External Solid-state Drives Review

I have recently spent ages looking for the best external solid-state drives that I can use for my digital data. I have to say – it’s super hard to decide which one to get! There are a lot of options on the market. The price varies a lot. And it’s hard to make a decision.

After spending a long time studying which option is the right option for me, I have decided to write this “Ultimate Guide” to help you choose the right external solid-state drive as smoothly as possible.

Let get right into it!

What is a Solid-state Drive?

The solid-state drive (SSD) is a data storage. It has no moving components. Indeed, if we open the case, we discover only a board containing the non-volatile storage chips on which data is stored. This means that solid-state drives use less power than traditional hard drives and are far more robust. SSDs can also access all data exceptionally fast.

External Solid-state Drives

The price of external solid-state drives has now fallen to a point where people with a particular need for very high-speed, robust, quiet or energy-efficient computers are starting to fix their system disks. As prices fall further, and as many of us store most of our data out in the cloud, a good number of people will end up using a computer without a traditional spinning hard disk.

External solid-state drives are effective ways or methods to increase the amount of storage you have to preserve digital data and take it with you wherever you go. So, you’re finally thinking of buying an external SSD drive to protect your data, images, videos and install your games in case your computer crashes, or you simply want to expand your storage, and you want to know what the best one is.

The simplest way to expand your storage is to buy an external solid-state drive, and as prices tumble, external solid-state drive has become the apparent option. A conventional portable hard disk drive still offers the best bytes for your buck. Except for top transfer speeds, an external solid-state drive may be a must.

External solid-state drives are indeed faster than magnetic hard drives. It reduces the bootup time and also speeds up the system to perform faster. External solid-state drives are the fastest way to keep your photography mobile, safe and backed up. External solid-state drives are the future and therefore, the indisputable fact that the cost of these drives has reduced tremendously makes it easier for everyone to afford it.

With capacities now reaching a whopping 4TB and even 8TB, you’ll have enough space to save thousands of ultra-high-resolution Raw files or around 16 hours of high-bitrate 4K video. With no mechanical components, SSDs are more resilient, reliable, fast and portable.

They are more immune to shock, vibration, and thus provide better protection for data. The world of portable SSDs may be a large one, and selecting the most straightforward device for your needs is often a challenge. But which do you have to buy? To help you decide which external solid-state drive suite your need, we reviewed some of the external solid-state drives in the market that is new and convenient.

SSD Advantages

  • No spin-up time
  • Fast, random access to data
  • Uses less energy
  • Far more robust
  • Silent

 SSD Disadvantages

  • High storage cost per gigabyte
  • Lower drive capacities
  • Relatively low write speed
  • Wear levelling reduces performance and causes encryption issues (Wear levelling is a process that ensures that no single block of flash memory is used too intensively. While it manages to prevent premature drive failure, this can also lead to the performance of an SSD decreasing over time. Wear levelling can also cause problems with data encryption techniques).

How to Choose the Best External Solid-State Drive (SSD)

Today, almost all SSDs store data in NAND flash memory cells. Flash is a form of computer memory that retains its contents when power is removed. However, the memory cells “wear out” each time you rewrite. The type of cell and their layout determines how often you can safely rewrite each cell before a cell (or group of cells if these are approached together) burns out. How do you figure this out? Search for the “TBW” (terabytes written) specification for the product of your interest. End-user SSDs endurance ratings are typically expressed in terabytes written or TBW. We also discovered that the larger a drive, the greater the TBW figure. If you are worried about maximizing SSD life expectancy, you should therefore, purchase the largest drive you can afford and leave it with as much free space as possible.

This is where the idea comes from to never fully fill your SSD. For some users in most situations, your SSD will last many years and potentially over a decade, so should we trust our data – SSDs today? My advice to you is to run your operating system off a very fast 1TB built-in SSD that only holds Windows, applications and the parameter values that Windows and application store, like registry, last file opened, preferences, last open window and its position, etc. Have all your serious data on external drives. You should never trust any data to one single drive. Any data you actually care about and you want to be there when you come back again should always be stored on at least two drives and ideally three.

7-   Adata SE800 Portable SSD – IP68 rating makes it extra-tough

External Solid-state Drives

Most ultraportable SSDS are rugged intentionally, but Adata’s SE800 Portable SSD takes the cake with a true, honest-to-goodness IP68 rating, meaning you’ll drop it within the pool or bury it within the garden without worrying of injury. It will lay lightly in the palm or ride easily in a shirt pocket. The SE800 comes in black or rich blue; however, its most salient physical feature is a captive plastic end cap that detaches to reveal the USB Type-C port. This cover (which protects the port during transport) is why it is classified IP68  rated against the elements. Without this, the drive would likely not survive the 1.5 meter, 30-minute submersion test that rating requires.

10-   OWC Envoy Pro EX 1TB

External Solid-state Drives

Shift your expectations of speed, performance, capacity, and portability with the Envoy Pro EX family of rugged, bus-powered, lightning-fast external SSDs. The OWC Envoy Pro EX SSD with Thunderbolt 3 is performance-tuned for demanding 4K/8K video production, VFX, augmented reality (AR), and VR workflows. Inbuilt is a robust, slim, and classy aluminum enclosure. It’s the right project drive that gives rugged military-level “MIL-STD810G” protection from the drops and bruises demanded of portable drives. Designed to run cool and silent, the OWC Envoy Pro EX is fully bus-powered with zero moving parts. It’s the perfect portable powerhouse for demanding environments that won’t let you down.


  • Ultra-high-performance M.2 NVMe SSD
  • Speed up to 2800MB/s
  • System requirements: macOS 10.13 or later / Windows 10 or later
  • Integrated Thunderbolt 3 cable
  • Available Capacities: 480GB, 1TB, 2TB and 4TB
  • Bus powered via Thunderbolt 3
  • Dimensions : 7.4 x 2.3 x 14.5 cm
  • Weight : 0.3 kg / 10 oz
  • 3 Year OWC Limited Warranty


  • It is built of aluminium and comes with a rubber bumper. It doesn't have any official drop ratings, but it should still be pretty durable 
  • Bus-powered
  • Drop-resistant
  • Solid enclosure


  • Windows booting not supported
  • Heavy for its size
  • Cable is short and permanently attached to the SSD itself, which you obviously can't lose, but it'll lead to a nightmare if the cable gets damaged in any way.


Now, although the OWC drive is the cheapest, we would not recommend it because of the bulky size and the permanently attached cable which can get damaged and render this drive useless. If you’re looking for a sophisticated and reliable drive, without caring too much about having the best performance, we would go with the Lacie because of its excellent portability, rugged design, IP67 water resistance, backwards compatibility with USB-C, excellent reliability and longer 5-year warranties and data rescue services. If you’re not planning on transferring very large files, we would recommend the Samsung X5 because of its sleek design, long Thunderbolt 3 cable, and massive 48GB of SLC cache that will help it be the fastest drive for transferring a lot of small files. Now, while the G-Drive doesn’t have the best-looking or compact design, it gets 10 feet of drop protection, a nice 5-year warranty, a long cable, and by far, the fastest performance out of all of these drives. If you’re all about reliability and you want the freedom to use your drive with not only Thunderbolt 3 but also USB-C, then the Lacie drive easily beats out the rest without a doubt.
