Best External Hard Drives in 2020

An external hard drive is an ultimate solution when you are looking for backup solutions for your computers. However, it has become increasingly difficult with numerous types and options. Before you buy an external hard drive, it is important that you know which type is the best for you, and it definitely requires a bit of research. We have simplified the task for you by having it all in here. External Hard Drives can be broadly classified based on four different attributes: Portability, Interface Connectivity, Usability, and the Operating System.

External Hard Drives

External Hard Drives classification based on Portability

Desktop External Hard Drives

The external desktop hard drives are mainly the highest capacity drives in the market. They are usually about the size of a book. They come in capacities of up to 6TB. Because of their big size, they are not portable and are parked on the desk. Being big and bulky also means that they are power-hungry, and are not one of those plug and play types; they mostly depend on external power sources. Desktop External Hard Drives are high on functionality and features. However, being big in size does not mean that it is the fastest, the external desktop hard drive is on the slower side.

Portable external hard drives are the popular ones on the block, with sizes of about a deck of cards. These portable hard drives, as the name indicates, are “portable”. With limited size, the capacities are also smaller. As of 2019, the popular capacities in this category are, 1TB, 2TB, 4TB, and 5TB. The portable hard drives have heaps of advantages, and one of them is that it is small enough to get powered via its USB port, and often does not need any external power; just plug and play. Though they might not be feature-packed, they are on the faster side of things. The portable hard drives are also much fancier than desktop hard drives.

External Hard Drives classification based on Connectivity

Most of the external hard drives have any one of the following interfaces: USB2.0, USB3.0, FireWire, and eSATA. Your choices might be limited to the type of ports that you have in your system, but if you do have a range of ports available, then you do get to choose the best one for you.

The USB (Universal Serial Bus) was developed during the 1990s and was mainly designed to standardize the connection of peripherals, both for the sake of communication as well as to supply power. The SanDisk Ultra Flair 128GB USB was the interface that effectively replaced the earlier interfaces such as the serial and parallel ports. It also replaced the need for separate power chargers for portable devices. The interface is so popular, that over 10 billion USB devices have been sold to date. Though there were various versions of USB released, such as USB 0.7, USB 0.8, USB 0.9, USB 0.99, USB 1.0, USB 2.0 and USB 3.0, only the latter three are in use for now.

The AmazonBasics USB 2.0 Printer Cable is one of the most common interfaces offered in most of the external hard drives, and one of the easiest to use too. The USB 2.0 was released in April 2015 and adds a higher maximum bandwidth of 480 Mbps, which is also called “Hi-Speed”. USB2.0 has been available for so many years that it would not be an exaggeration if we said that each and every computer, including desktop PCs, laptops, netbooks and servers in both the worlds of Windows and Mac.

However, the Hi-Speed, which was then considered as an advantage, is now quite a disadvantage, because, the 480mbps is quite limited, translating to just 30 – 35 Mbps maximum bandwidth for most of the typical storage applications. Even though this seems to be more than enough for most of the device types for some casual storage, but as the capacity of the external hard drive increases, on a regular basis, you will crave more throughput.

To eliminate this disadvantage of limited bandwidth, SanDisk Ultra CZ48 32GB USB 3.0 was developed and announced on 19th November 2013. SanDisk Ultra USB 3.0 has transmission speeds of up to 5gbps, which is about ten times faster than the original USB 2.0. This technology significantly reduces the time that is required for data transmission. In addition to this, it reduces power consumption and is even downward compatible with USB 2.0.

Super Speed Certified USB

Some of the best USB 3.0 compatible drives take full advantage of the amazing speed of this technology. However, some of the cheaper USB 3.0 is not so fast, and for now, USB 3.0 is only available in very few PCs. That said, USB 3.0 is the fastest interface of all, and hence the external hard drives with this interface top the list of speedy drives.

Fantom Drives 4TB External Hard Drive

Fantom Drives 4TB External Hard Drive

eSata is a Fantom Drives 4TB External Hard Drive variant for SATA and is basically meant for external connectivity. eSata is mainly aimed at the consumer market and hence was introduced to the market of external hard drives, which was then served by the FireWire and USB interfaces. The Fantom Drives 4TB External Hard Drive Serial Advanced Technology Attachment is much faster than the USB2.0 interface, and that is by a lot. Yes, a lot, as it is about four times faster at 157Mbps. Even though USB3.0 has a much faster theoretical transfer speed, of 4.8gbps, experts have reported that eSATA will work much better in real life.

However, the major issue is that eSATA is not as universal as its rival USB2.0. Hence, most of the computers do not have the eSATA port, stopping most people from buying eSata based external hard drives.

Apple Thunderbolt to FireWire Adapter

FireWire, which is also known as IEEE 1394 is an interface that has been around for a long while. FireWire is actually Apple’s name for this High-Speed Bus. Apple initiated it and was developed by IEEE P1394 Working Group. This research and development were largely driven by Apple, however, most contributions were made by the engineers from Texas Instruments, IBM, Digital Equipment Corporation, Sony and STMicroelectronics. There are two major versions of FireWire that were employed in external hard drives; FireWire 400 and FireWire 800.

With the FireWire 400, you will be able to get 400mbps throughput along with the isochronous transfer. This helps with real-time data transmission for digital video. The next version, FireWire 800 has twice the throughput at 800mbps. However, none of these two versions became mainstream. Though the interface is widespread, it is not even close to the popularity of USB. Some of the future FireWire standards such as 1394d can reach up to 6.4gbps, but there are chances that they are not mainstream either. A final nail on FireWire’s coffin was that Apple has recently ditched FireWire from its consumer line in favor of USB.
