I bought a video editing system for my friend in August 2002. It has a WD 120 GB, 7,200 RPM hard drive with 2 MB of cache. The NLE software regularly needs to read/write 21 GB of data from/to the disk. No coolor is necessary yet.
Axeman, Which applications do you see the most performance benefit with your 15K RPM drives? Iâve never had to wait much for apps to launch. Often I just keep them running. How much RAM do you have? When you launch these apps, are you able to tell if they loaded from the hard drive or your (much faster) RAM cache? -p
want to keep systems cool?? these guys even sell a water cooling system for your pc go to www.pricewatch.com and click on fans..........................
I have 512 megs of ram. All applications launch significantly faster, even after a fresh boot with no cache. My 2ghz systems has the 15,000 rpm drives, and my 2.2 ghz system as 7200 rpm drives. System performance, in general, is obviously faster on the system with the fast drives, even though the cpu is a little bit slower. When back testing against mountains of data, the hard drives make a huge difference. CPU delays are nothing compared to IO delays which are measured in milliseconds. peace axeman
Very true. What software framework do you use to backtest? What quantities of data are you analyzing? Iâve done backtesting on 4 years of daily data (10 indicators) for 3000 stocks, using per-week rolling trials. Yet disk access constituted about 3% of running time, never an issue really. Of course I was using 1 GB RAM, with half of that as disk cache, and I used I/O efficient code.
Put an "Aqualung" on it, Jethro !!! Seriously though gnome, I've been running a 7200 20g WD for a couple of years now and so far it's been one of the most reliable HD's I've had. (no extra cooling) I've had segates and maxtors puke within a year. So far so good with the western digital. I think that leaving them running instead of daily on and off might also help with longevity, although I have no proof of it. My logic: light bulbs usually go as soon as you turn the power to them and seldom when they are just burning. Also, I keep my pc on the floor (the coolest spot in the room). Hope this helps, plumlazy PS. Drying in the cold sun Watching as the frilly panties run. Feeling like a dead duck spitting out pieces of his broken luck.
Then try this sometime http://www.planetrock.musicradio.com/rockplayer/rocktuner.htm# for whatever reason, I can't get it to work right now, they may be working on the server? It's coming out of London (4am there now) When it's working...lol...it loads and runs on it's own player...nothing to download...just click and listen. Try it out later though, it's a pretty decent station. Listen to several songs and I think that you will probably agree. Also, you can minimize it (it keeps playing) and open a new window for surfing.
