Cloud storage is convenient, you can view your files with just a few clicks, anywhere anytime. However, without an internet connection, you will be left out from accessing your files. Eventually cloud storage will be the prioritized storage option, until then, it is still a good practice to have a copy of your files in external drives.
Why choose external drive you asked? The reason is simple, no matter what happens to your computer or internet connection, you still be able to access your files from the external drive.
External hard disk is something that is familiar to those that have owned at least one or more to back up their files and data. External SSD has become more common in recent years but what makes it different from external hard disk.
SSD vs. HDD
Just like internal drives, external drives also can be found in two different technologies; HDD and SSD. HDD (hard disk drive) uses spinning magnetic disks to store data. Read/write heads change this data as necessary, so you will hear their iconic spinning sounds when they are working. SSD (solid-state drive) in the other hand uses tiny gate transistors in cells that can flip on or off based on electric pulses. They have no moving parts, hence the name.
SSD is significantly faster than HDD in many instances but it can be very expensive. HDD is cheaper, but also larger in size, slower in speed and more easily damaged. For external drives, it is usually best to choose a SSD except in particular circumstances.
External SSD offer all the benefits of internal SSD without the need to swap out the drive inside your computer. Other than that, external SSD can be used with multiple systems and devices. Plug it in and instantly get the benefits and speeds of an internal SSD.
Transfer speed is incredibly important. If you transfer files back and forth to an enormous drive regularly, you do not want to wait forever for the transfer to complete. There are two factors that determine how fast your external drive can operate; the storage technology used and the connector it uses.
In general, SSD is able to process data faster than HDD. External SSD tends to be more expensive than their HDD counterpart and often have less storage capacity. You do not need one or the other, as there are larger SSD you can buy for a premium price.
USB Interfaces are confusing as it is, with USB 4.0 being the new standard, the classifications still confusing as ever. Generally, you will find the classifications as below:
- USB A ports / USB C ports with USB 2.0
- USB A ports / USB C ports with USB 3.1 / 3.2 Gen 1 support up to 5Gbps bandwidth
- USB C ports with USB 3.1 / 3.2 Gen 2 support up to 10Gbps bandwidth
- USB C ports with USB 4.0 support up to 40Gbps bandwidth
The ports themselves are backwards compatible, so an USB 4.0 port will work just fine with drives that use the slower interfaces. However, things cannot be the same for the drives. For instance, plugging a USB 3.2 Gen 2 drive with a laptop that can only handle USB 3.2 Gen 1 will still work but not able to utilize the maximum transfer speed.
SSD drive can transfer data between 30mb/s – 40gb/s, depending on the drive while HDD can only offer up to 220mb/s transfer speed. Clearly video editors would want to do all their editing on a SSD. It just gets the job done faster and it does not need to get tied up the computer. In an optimum situation, exporting a video using external SSD drive would take you around 20 minutes while external HDD drive might take you double the time or even longer time.
