Any mechanical hard drive that go like the wind?
Hi All,
I have a customer who really, really wants RAID 1. (She is well away of the difference between backup and RAID.) Problem: no TRIM support for RAID 1. Are there any mechanical hard drive that go like the wind out these? Sort of like a (poor) substitute for SSDs? Many thanks, -T |

Many thanks, -T Any 3.5" 7200RPM drive does about 900MPH. That's a pretty fast wind :-) (Sorry, couldn't resist) :-) In a former life, I had to deal with customer requests for product improvement. If I asked what they wanted, the answer was always, "more." Didn't matter what it was, they just wanted more. When I asked why, they had no idea why...more is better. Often, a better approach to doing things was cheaper and more effective. I have a 3.6GHz. P4 with a pair of 15KRPM drives in RAID. Back before it was obsolete, I ran some experiments against a similar machine with a 7200RPM drive. Sure, I could construct a benchmark that showed bigger numbers, but sitting at the console, I really couldn't tell much difference. One thing that did go faster was the little wheel on the utility meter. If the program is small enough, maybe a ramdrive would help. |

They provide roughly 75% of the performance of an SSD. e.g. http://www.ebuyer.com/544878 -- :: je suis Charlie :: yo soy Charlie :: ik ben Charlie :: |

Yes, try out the hybrid HDD's, which include both a mechanical portion and an SSD portion. The SSD portion is nothing spectacular, only about 8GB, but good enough to cache most of the important Windows files, which get used the most. BTW, even if there isn't support for TRIM through firmware RAID, Windows' software RAID should have full support for it. Software RAID should be just as fast as firmware RAID, and more portable.

Hi Mike, I always go for the 7200 units, as they seem to have a much longer lifespan. And, I also haven't been able to tell a speed difference. I used to go for 5600 (or was it 5400?) ones if I could find them, as they seemed to me to run noticeably cooler (which obviously contributed to the lifespan) - but I don't think anyone makes those any more, they're all 7x00. It wasn't as if we were talking an order of magnitude difference, like doubling RAM or more cores in the processor, and any time where HD speed comes into play, there's such a slow-down anyway that a less-than-50% ratio didn't make much difference. (Obviously it would in some applications/systems - video processing comes to mind - but if you're using those, you throw more RAM, and/or go SSD.)
