Video written material is one among the foremost hard to please tasks you'll be able to execute on a laptop. a contemporary video-editing program like Adobe Premiere needs high performance from the processor, RAM memory, GPU (if exploitation GPU acceleration), also as storage drives. selecting a quick storage answer may be a bit more durable than selecting the quickest laptop processor, as there area unit additional tradeoffs concerned. [1]the most important drives aren’t perpetually the quickest, and speeds will vary an excellent deal. This guide was created to assist you to decide on the proper storage drive (or drives) for your written material wants, from the little to the massive.[2]
How much information measure does one need?
"The opening in selecting a drive is to work out what quantity cupboard space you wish, also as how briskly your information may be kept and retrieved."[3]
The first step in selecting a drive is to work out what quantity cupboard space you wish, also, as however quickly your information may be kept and retrieved. the most important determinative issue is what codec and backbone you may be written material in primarily since the quantity of house that completely different video codecs occupy varies wide. 1080p ProRes HQ, a well-liked written material codec, can set you back concerning 112GB [4]Associate in Nursing hour, whereas 1080p AVCHD solely takes up concerning 11GB.[5] » Chevrolet Camaro Car 2016 Information Details and Review

It's also necessary to not confuse bits and bytes. Most codecs rate their speed in bits per second, whereas most exhausting drives publish their speeds in bytes per second. XDCAM EX's 35Mb/s is truly solely four.5MB/s. A handy tool for determinative the quantity of information measure you wish is that the AJA DataCalc app, that is accessible for Windows and mack at AJA's website. it is also out there for iOS within the Apple App Store. This tool enables you to decide the codec you may be exploitation, and it tells you ways abundant information measure one track of that codec wants in bytes per second.[6] [7] [8]
Once you recognize what quantity information measure one track of the codec needs, your next step is to work out what percentage tracks you're progressing to ought to reproduce quickly. If you may solely be doing straightforward written material with some transitions and text overlays, then double the information measure is maybe enough. However, if you intend on doing multi-camera cutting in real time, or employing a sizable amount of layers at the same time, you're progressing to want much more. Below area unit some widespread codecs, also because the amounts of information measure they require:
- AVCHD 1080p at thirty FPS - 3MB/s
- XDCAM EX 1080p at thirty FPS - four.5MB/s,
- ProRes 422 1080p at thirty FPS - 21MB/s
- ProRes HQ 4K at twenty-four FPS - 106MB/s
- Single 3.5" drives
If you may be written material HD content while not a large variety of tracks, then a superior three.5" drive can in all probability be quick enough to satisfy your wants. Current high-end 7200 revolutions per minute three.5" drives area unit able to faithfully deliver speeds at 150MB/s or higher, in capacities as high as 4TB, that is enough to reproduce varied tracks of gently compressed videos, like DnxHD or ProRes. Some suggested three.5" drives area unit the 4TB Western Digital caviar Black, the 3TB Seagate spiny-finned fish, or the 4TB Hitachi Deskstar. All of those drives ought to offer you a minimum of 150MB/s of sustained transfer speed for video written material.[9] [10]
