Now as we know the basic difference between the two types of drives, the biggest question arises- which one is right for data backup. It stores data on interconnected flash memory chips that retain the data even when there’s no power. Both the devices use the same NAND technology to store data. SSDs are somewhat similar to USB drives but larger in size. SSDs work on flash memory and the lack of spinning parts make these drive more durable and energy-efficient. It is electronic storage that has no moving parts and stores data in microchips.
However, these are more advanced drives that store information on flash memory that consists of individual memory cells. Similar to traditional hard disk drives, solid-state drives also perform the same basic function of storing data. Also, more platters inside the drive mean more storage capacity. The higher the speed, the faster the hard drive performs. The spinning speed of platters determines the read/write rates.
To read or write data, the head hovers above the rotating magnetically-sensitive platters. The spinning hard drives work on the non-volatile storage and use an I/O controller and firmware. It relies on the mechanical movement of these parts to acquire information, which makes them slower and more prone to damage than the SSD. All HDDs use a mechanical arm to move and read data. A typical hard disk drive consists of many small, moving parts such as magnetic heads, spindles, and spinning platters. Hard Disk DriveĪ Hard Disk Drive, known as an HDD, uses magnetism to store data. Read further to know the difference between the two devices. Both external SSD and hard drives may look similar in appearance but their technology is different and they store data in different ways. Besides storing data, the external HDD and SDDs can also be connected to different devices for transferring files. Unlike internal drives, an external hard drive or SSD is plugged directly into a desktop or laptop to get additional storage space. So, let’s find out the differences between HDDs and SSDs in terms of speed, capacity, cost, and lifespan. If you also need a device to gain extra storage space then you might wonder whether to pick an SSD or HDD. However, the availability of plenteous options also makes it easy to get confused.įor most users, the biggest dilemma is to choose between an external HDD and an SSD.
EXTERNAL PORTABLE SOLID STATE BACKUP DRIVES FOR MAC UPGRADE
So, whether you’re running out of storage space or looking to upgrade to a better hard drive, it’s easy to find a device that meets your needs and suits your budget. With technological advancements, external portable storage devices have become more compact and offer higher capacities, faster transfer speeds, and better reliability.
When it comes to data backup, users have got multiple options today. Over the years, data storage technology has evolved from floppy disks and CDs to external HDDs, USB flash drives, and the latest external SSDs.
