How to choose an external hard drive for Mac
In today's digital age, saving your work, memories and sensitive data is essential. Storing and accessing huge amounts of digital files is now very easy. It is of the utmost importance to save copies on an external hard drive as a safeguard against possible data loss.
As with almost anything digital, external hard drive technology continues to improve and become more affordable.
Storage size
The amount of data that a disk can store is an essential element. Photographers, videographers, editors, digital artists, music producers and other creators require plenty of space to back up.
Having at least one terabyte (TB) is considered the norm these days, although it's often a good idea to invest in as much storage as is reasonable and affordable based on your needs.
SSD vs HDD
Two main types of external hard drives are solid state drives (SSD) and hard disk drives (HDD). The former fall into a more recent category of hard drives consisting of flash memory. SSDs are fast, portable and virtually immune to damage from drops. Their biggest disadvantages are cost and potential for failure.
Hard drives are mechanical and run a bit slower than SSDs. However, you can get more storage for less money, making them a great choice for uploading data. When kept safely, hard drives will usually last longer due to their mechanical composition.
Transmission Speed
Transfer speed refers to how fast a disk drive can transfer data from a computer and how fast a computer can read it from the disk. One disk is sufficient for most users with moderate file storage needs.
But if you plan to run software from an external drive or write real-time data to an external drive, such as in video editing or music production processes, you might want to consider an SSD for faster speeds.
Portability
Another factor is how you intend to use the external hard drive. A desktop drive is ideal if you just want a high-capacity, live-plug drive to use when you're in your office or studio. On the other hand, nothing is more convenient than a portable disk.
Connectivity
The vast majority of external drives these days connect via USB-A or USB-C. You shouldn't have any connectivity issues when you buy an external hard drive for Mac. Additionally, whether a drive is bus-powered or requires an external outlet is important.
Portable drives draw power directly from the computer, while desktop drives require an outlet.
