Online cloud services are a popular way to store digital goodies these days, but nothing beats the security and peace of mind that comes with having your data on your own physical hard drive (and so- saying “cloud” is just someone else’s computer, anyway). It’s a fairly large market that covers everything from compact portable hard drives to professional grade network attached storage systems, but whatever you’re looking for, we’ve probably got it here. Read on to see all the best deals and discounts on cheap external hard drives available this month.

How to choose an external hard drive
The first two steps in choosing an external hard drive are to set your budget and determine the size you need. As cheap as storage per gigabyte is these days, the classic tradeoff between hard drive size and portability still holds; basically, is your storage space or physical size your main consideration? If your external hard drive is intended for home and office use on a single workstation and will fit more or less in the same location, then storage space is more valuable than mobility. If, on the other hand, you frequently transfer data from one PC to another, a portable hard drive may be a better choice, even if you sacrifice storage space for a smaller footprint.
The exact use of your hard drive will also be taken into account in your purchase decision. If your external hard drive or SSD is only for file storage then this is pretty straightforward, but if you are going to regularly read and write to your external storage (e.g. doing video editing directly from the drive itself rather than from your computer’s system drive), you’ll want to make sure you’re getting something that has good read and write speeds and uses up-to-date connectivity standards such as USB 3.0 . For more details on external hard drive designs and features to look for when making your purchase decision, read on.
HDD vs. SSD
Storage drives fall into two main categories: traditional hard drives, or hard drives, and solid-state drives, or SSDs. Most hard drives, until recently, were mechanical hard drives. These have movable disks (called platters) inside, where the data itself is written and read. These traditional hard drives have largely fallen into disuse for use as system drives, but their larger capacities and much lower cost per gigabyte still make them a very popular choice for external storage.
In recent years, we’ve seen the SSD revolution. These drives are basically a type of flash memory, where data is written to chips rather than magnetic platters, meaning there are no moving parts, which means faster read / write speeds. fast as well as increased long-term reliability (in theory). However, these drives are generally smaller and considerably more expensive per gigabyte than hard drives; the trade-off is that they’re what you’ll typically find when looking for portable external hard drives small enough to carry around in your pocket.
There are also hybrid hard drives, sometimes referred to as SSHD. These hybrid drives are basically hard drives with built-in flash storage (usually a fairly small amount) where your most used files are stored and played back, combining much of the responsiveness of SSDs with the greatest storage capacity. hard drives. These might be worth the price if you need the optimized storage of a hard drive, but expect to actively read and write to the external drive.
Are all external hard drives SSDs?
Virtually any hard drive can be used as an external drive with a suitable hard drive enclosure, and these are available as both SSD and HDD. Although solid state drives are a quick replacement for hard drives for use as internal system drives (the hard drive inside your PC on which your operating system and other software are installed), hard drives remain. extremely popular for external use as they are much, much cheaper per gigabyte and therefore give you a lot more storage capacity for your dollar.
Are external hard drives reliable?
An external hard drive is simply any hard drive or SSD – just like those found in laptops and desktops – that sits inside an external enclosure. This enclosure has some means of connecting the hard drive to your computer or other device, usually a USB port, and may also (depending on its size) have some kind of power adapter. This means that an external hard drive will be about as reliable as any internal hard drive as long as it is from a reputable manufacturer. Stick with proven manufacturers like Western Digital, Seagate, SanDisk, Samsung, and Kingston, and your data should be in safe waters.
Are external hard drives fast?
One very important thing to consider is read and write speed (the speeds at which data is downloaded and uploaded to the hard drive), but this is less of a potential trap than in the past. Even traditional rotating hard drives (HDDs) today offer pretty solid read / write speeds, with 7200 RPM being the norm. Make sure to check this out and avoid the ones that use the old standard of 5,400 RPM, although these are less common now. SSDs naturally offer the best read / write speeds, but, as explained above, offer the least value per gigabyte.
Don’t overlook connection speeds, either. The fastest read / write speeds will be obstructed when transferring data over a connection using an older standard like USB 2.0. Make sure your external hard drive is using at least USB 3.0 (which is about ten times faster than USB 2.0 in comparison).
Do external hard drives need power?
Hard drives are electronic devices that need to be powered from an external source, but that doesn’t mean all external hard drives have to be plugged into a wall. Most can usually squeeze enough power from the same USB connection they use to transfer data, but larger hard drives may require an external AC adapter that came with the hard drive. This isn’t a big deal for most, but it’s something to be aware of if power outlets are prime real estate where you’re going to be installing your drive.
