Macbook For Video EditingThere are two types of external hard drives for Mac: 3.5 inch desktop drives that have their own mains power source and 2.5 inch portable external drives that take their power from your Mac. Portable drives will easily fit in your jacket pocket. If you work with libraries of large image files, or in audio or video production, you need to be selective about your external hard drive. Writing files directly to an external drive can incur some hefty performance demands, so it's best to determine your needs before you buy a drive. With the ever-increasing data-transfer demands brought on by more megapixels, higher audio bit rates, and higher-resolution video—keeping up with all of that data can be a burden. The first thing to determine must be how much overall storage space you need and, then, what data-transfer speed your projects will require. Each medium is different, as is every user. To break it down, we'll discuss the writing of data to an external hard drive while editing video, for use in photo editing and running audio projects. Drives for Video Production No one creates a greater need for media storage than a videographer, especially those working in 4K. To prevent getting bogged down by a sluggish external hard drive, you need fast drives. These days, the default spin rate is 7200 rpm, though even faster drives are available for a premium.

Do you intend to use eSATA or set up a RAID array because a single drive can't handle your output, so you need multiple drives? Interface Speeds: USB, Thunderbolt, and Beyond The latest in high-definition video requires a whopping 106 MB/s of bandwidth. But if you aren't working in the latest ProRes HQ 4K codec, you can get by with less speed. By contrast, AVCHD 1080p video at 30 fps requires just 3 MB/s. But your hard drive's maximum write speed should exceed this by as much as is comfortable for your budget, because other issues, such as caching, also can impact performance.

USB 3.0 is capable of 625 MB/s. However, check the rated speed of the external drive (it likely can't move data that fast). For example, the is rated at up to 180 MB/s.
