Advice Please: The Importance of Hard Drive RPMs
Can anyone tell me if hard drive spindle speed is an important factor
to consider when purchasing a hard drive? Or should I just concentrate on average latency, average access, and max. full seek time? I ask because two hard drives with a data rate of 80mps can differ in these other respects. Thanks a lot. Darren Harris Staten Island, New York. |

Spindle speed will drive the limits of seek and access times. You'll probably find a significant improvement with speed when you compare groups of "equivalent" drives with 5400, 7200, 10K, and 15K RPM speeds. |

Unless you're setting up a server that will be accessed by many, go for the cheapest drive per byte stored. -- The e-mail address in our reply-to line is reversed in an attempt to minimize spam.

Unless you're setting up a server that will be accessed by many, go for the cheapest drive per byte stored. Unless you've got bucket loads of memory, your OS is gonna be using a swap file of some kind with reasonable regularity. Disk speed will make a fairly large difference here. In any standard desktop system I'd go for a 7200 rpm drive, you got a large budget and want a fast system, get a 10k raptor. |

Please people, show some restraint and learn to ignore this TROLL.
This is another very obvious troll question. "Darren Harris" wrote in message om Can anyone tell me if hard drive spindle speed is an important factor to consider when purchasing a hard drive?

Alright, I'll concede there, but a 7200 will still provide a very noticable performance increase over a 5400. Not just in drive benchmarks, but in day to day computer usage. |

Is this true always?

I think the devil will be in the details. If you mostly just browse the Web, I doubt your disk will be exercised much. If you do a lot of video editing, you probably want something pretty fast -- most likely RAID. There's a whole range in between (and perhaps beyond). -- The e-mail address in our reply-to line is reversed in an attempt to minimize spam. Our true address is of the form . |

It is true in the general case. There may be exceptions, but I can't think
of any off hand... "Lil' Dave" wrote... Is this true always? Alright, I'll concede there, but a 7200 will still provide a very noticable performance increase over a 5400. Not just in drive benchmarks, but in day to day computer usage. |
