If transfer or storage of data bogs down at the video editing computer hard drive...You won’t experience the full power of your system no matter how much processing power you’re packing...!
Let's take a look at this vital component of your editing computer…!
While sometimes overlooked... The video editing computer hard drive plays an important role in the system’s overall capacity and performance which can be vital in ensuring a smooth-running, glitch-free video editing experience.
Hard drives differ greatly in capacity and performance. Over the last several years advancements in technology have pushed the envelope in these two areas and video editors in particular have benefited. An understanding of each will help you choose the best hard drive for your video editing computer.
You’ve seen how a record spins on a record player... Well...that's happening in your hard drive too!
The faster the disk spins the faster the arm is able to seek out and or copy (read/write) data to or from the disk. So... the higher the Revolutions Per Minute, or "RPM", the faster the read/write speed of the hard drive.
The EIDE (Enhanced Integrated Drive Electronics) specification was set forth by the Western Digital Corporation in 1986 as a successor to the AT drive interface.
EIDE uses a 40-pin male connector on the drive itself that is connected to a 40 or 80 wire ribbon cable... This cable connects to an EIDE interface on the system's motherboard that is capable of supporting two devices per channel. EIDE is capable of transfer speeds ranging from 16 MB/s to 133 MB/s.
The SATA (Serial ATA) specification was released in 2003 as a successor to the EIDE interface for hard drives and optical drives.
The SATA hard drive interface consists of a seven-pin data cable which connects the drive to the system motherboard.
SATA hard drives are capable of transfer speeds of 1.5, 3.0 and 6.0 Gbit/s. With 6.0 Gbit/s being pretty much the norm these days even with the larger drives. The SATA specification allows for "Hot Swapping". Hot swapping enables drives, under specific hardware configurations, to be removed and installed into a system without the need for a system shutdown.
In much the same way that RAM is essential in providing lightning-fast access to commonly used CPU data... Hard drives use a cache buffer system (embedded memory in the hard drive) to speed up the data transfer performance of the drive.
Hard drives typically offer 16 MB or 32 MB of cache buffer. Higher-end computer systems usually provide a 32 MB buffer. For maximum data processing... Hard drive manufacturers offer drives with up to 64 MB of cache as is the case with the newer large terabyte hard drives.
Note: The differences in cache size greatly effect the time it takes to locate a file on the video editing computer hard drive and feed its data to you.
If you don't need a lot of speed you probably can tolerate the difference easily but... For video editing you need all the speed you can get! Trust me… As a video editor you love...
Anything that gives you any tiny margin of improved performance in your video editing computer!
A larger cache is really a great help with quick access to large sequential blocks of files… But less help if your operating system has to jump around all over the disk looking for files that have been stored as fragments in various places on the disk and not in sequential blocks.
The data capacity of a hard drive is measured in "bytes" and one billion bytes is a "Gigabyte" or "GB" for short. 1000 GB is just a short way of saying "1000 billion byte hard drive."
The more space available on the disk the better, and the more expensive the drive generally is. Over the last decade, the storage capacity for standard 3.5-inch hard drives has grown by orders of magnitude unimagined by the early hard drive manufacturers... And... in the past few years alone…
The computer industry experienced another leap in hard drive capacity with the introduction of the terabyte storage capacity hard drives. A Terabyte is approximately one trillion bytes, or 1,000 Gigabytes...
The TB (Terabyte) hard drive has quickly established a new standard in storage capacity in the video editing computer with even bigger drives on the way.
Choosing the best drive for your computer is a decision that is based on how you use your computer. The key question is...
* Do you use it for everything or just video editing?
In digital video editing you want to have fast access to the video editing computer's operating system (OS) and... You want your video editing software program to have fast access to the data it needs.... So... if you are doing a lot of video editing... Which always calls for...
Then go for the fastest RPM or "spindle speed" you can find. A 10,000 RPM drive would be best!
If you use your video editing computer for everything and you are storing a lot of video that you are not currently editing, along with other large files such as...
I would say a big SATA hard drive is your best choice. The big SATA drives will provide you with plenty of storage space and are fast enough (7200 RPM) these days to keep up with your video editing requirements as long as you're not producing involved videos with lots of special effects.
And that, of course, includes maximizing their video editing computer hard drive performance...!!
