Background on Hard Disk Drives
Traditional hard drives operate by storing data on one or more spinning metal disks, called platters. The more platters there are in a drive, and the more data that can be crammed onto each platter, is what determines the overall storage capacity of a given hard drive. Having more platters also tends to mean louder drives, though rotational speed affects that as well. Rotational speed also impacts the drive’s performance: if platters spin faster the drive can reach data in different areas more quickly and read or write more information per second.
The alternative to hard drives is solid state drives, which are many times faster but much more expensive for the same amount of capacity. The price gap is dropping over time, so SSDs are becoming more and more preferred for us. For performance, reliability, and noise reduction, SSDs are really the way to go.
The magnetic platter hard drives are great it you need storage as their price per GB is MUCH better than an SSD. For a primary drive however, I recommend an SSD as typically platter drives have Random Read 4KB performance of less than 300 IOPS while most standard SSDs have better than 94,000 IOPS, What this means is that with an SSD, you will have much, much faster boot times and program loads if you use an SSD as your primary drive.
I would recommend using a Gold drive if it is important to have high capacity with good throughput that can actually be taken advantage of. These drives are noisy and have noticeable chatter when they're not in use. If storage is what's required get a Red drive, better acoustics and respectable performance.
