The Hard Drive Factor

While often overlooked, the 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 experience. If data bogs down at the hard drive, you won't have a chance in Zanzibar to experience the full power of your system, no matter how much processing power you're packing.

Hard drives can differ in capacity and performance. Over the last several years, advancements in technology have pushed the envelope in these two these areas and an understanding of each will help you chose the best hard drive for your needs.

The truth is that 7200 and even 10,000 RPM drives are to slow and we need something much better to improve system speed. Building an overclocked dual core system with 4 gigs of memory and then having to put in a slow 7200 drive is kinda sad.

Also it would be nice if motherboards came with better raid controllers with xxx megs of cache, which would show some real world improvements and not just endless benchmark test which mean nothing.

If you're going that far out of your way to buy top of the line you may aswell put down money for a 15k SCSI drive.

Then you need a scsi card as well. 15k SCSI + RAID Controller = $$$$$

It rules in scenarios that require concurrent, multi-user access to files (servers). Aside from that they're a waste of money on the desktop.

You know, 7200 and 10,000 rpm do not represent transfer rates. It is simply how many revolutions per minute the spindles make. You may think that a 7200 rpm drive is 10 year old technology, but the fact is that as the bits on the platter become more dense the number of bits passing the read/write head per second increases (this is the same reason why DVD-ROM drives have transfer rates so much higher than CD-ROM).

The truth is that you seldom do sequential I/O. Seek time is far more important to performance than peek transfer rate and seek time has almost nothing to do with RPM.

SCSI drives (even the slower 10,000 rpm versions) are far faster than IDE or SATA because the arms are faster and can seek in less time. A good SCSI drive might have an average seek time of 2-3ms where user-grade drives are normally between 6-12ms (very big difference).

Wow, a one page article, why doesn't it actually compare different brands, models and help decide whats best for you? This is like the first page in the review... Where's the rest?

Becaus it's an artical. Not a review or Round-up.

On the other hand, it could have been allot more interesting if it was more in depth....
