It's worth mentioning that cloud storage, online syncing, and cloud backups are not the same things, even though such phrases are often used interchangeably and some providers offer both or roll both into one.Ĭloud storage is essentially software that ensures a selected document or collection of files is readily available from multiple different devices. So you're always running that risk with hard drives and have to be marginally more careful moving devices whilst they continue running. From computer cases to game consoles, you don't want to move a device whilst a disk is being read.

Read/write arms found in hard disk drives, on the other hand, make them a little riskier to move around than devices with SSDs. It's not really a problem for most people because we're so used to the low-level hum that most computers make, but SSDs are quieter than hard drives because they don't have moving parts that produce sounds. They're also more energy-efficient (because they aren't spinning all the time) so use up less battery life. They take way less time to boot up and everything from transferring files to general system speed is much quicker on SSDs. But that's not the only reason.Īlthough SSDs are much more popular nowadays, HDDs still have their uses.Īs aforementioned, SSDs are the clear winners when it comes to speed. HDDs – as the more senior technology that's less in demand – are a bit cheaper than SSDs, and this gap may widen even further in the future. What is the best local backup option?īoth HDDs and SSDs have their own advantages, despite fulfilling a very similar function. These chips are somewhat comparable to the ones used in USB drives, but they're usually speedier and more dependable. NAND is just a type of non-volatile flash memory that doesn't need power for storage. Solid State Drives have no moving parts and no storage disks instead, the drive's memory capacity is dictated by the size of the NAND memory chips it houses. They are much more robust, faster, and can store more data than hard disk drives in a much smaller space, which is why they're more commonly installed on newer computers. Sold State Drives are much more popular than hard drives these days. The speed at which the disks inside the hard drive are spinning determines how quickly the data can be read by your machine. Hard drives are connected to the motherboards of computers, laptops, and other devices, transferring data on request.

The data that needs backing up is both loaded onto these disks and can be accessed later with a read/write arm. Today, hard drives are essentially little compartments containing single or multiple platters (spinning disks to you and me) stacked on top of each other. 5 MB was also the storage capability of the first small (for the time) hard disk in 1980. In those days, hard drives were physically bigger than most computers are today. Hard disk drives were first put to use by IBM as far back as 1956 but they could only store under 5 megabytes of data, which is roughly enough to store a single song from Spotify. There are a number of different methods to back data up in this way, and it'll likely be very different depending on the device. To say that data is backed up locally is to say that it is stored somewhere on the device you're using.
