Re: How realistic is a NAS for main storage?

I realize this thread is old but .... The problem w/ reaktek81xx is that they generally don't support jumbo packets and that's IMO a disaster for high performance. WRT NAS speed. A disk may have a 120MBPS sequential transfer rate, but after introducing non-sequential access of files and the overhead...

Re: Low Idle Power Core i5 System?

Hi all, I've been researching the ideal low power system. I have an Atom PC and it's great at taking less than 35 watts, but it is getting a bit too slow for me. I've been reading Tom's Hardware Review article that you can get a i5 to 25 watt idle load and was hoping I could achieve something simil...

Sincere thanks for the reply Mike. The question of durability/reliability cannot be answered by any review site w/o vast resources. Fair enough, but how about seeking at least the manufacturers MTTF/MTBF. For example I see the edac power units for the PICO have a reported MTBF of 30,000 hours, which...

Microcenter i5-650 $120 in store deal

Microcenter is selling the Intel i5-650 for $120, in-store deal only. This compares to Newegg @ $195.

The -650 and -660 (~$205) are the same except for the 3.2Ghz, vs 3.33Ghz clock rate.
Great discount for a 3.9% slower clock IMO.

Your average power consumption may always be under 60W but momentary demands are likely to exceed that number and cause excessive voltage drop which is extremely likely to cause the processor/memory to go to an incorrect state.

freedos is (last I looked a couple yrs ago) an open source clone of MS-Dos. No real feature upgrade. I'd consider it a Neanderthal OS, (a kernel actually) and not viable myself.

There are several Linux distros specifically aimed at low dram and legacy cpus. Check out puppy Linux for example.

From a theoretical point of view: NO change in temperature. :-) Yeah a slight change in temp for a non-ideal gas, but it's mostly entropy.

If yes, could we possibly make heat pipes even more efficient by accelerating the internal gas transport? Pehaps sli...

Just to add to TeeJay's sage advice,

Not only are the two drives noisier, but under Windows the practical speed benefit of a RAID0 configuration is negligible !!! The magazine "MaximumPC" did some nice benchmarks to evidence this point.
