4100 write speeds

[Morpheus256]

so after testing my 4100 for a while, ive decided that the write speeds arent nearly as fast as my old fileserver. im getting around 26mbit for writing and 32mbit for reading. this is with the origional quantum drives.
im planning on upgrading to 4-160's (i know 128gb limit) will the write speeds atleast get faster?
has anyone perfoirmed a before and after with upgrading the drives, and the performance?

I could not say how fast my 705N/4100 was before I put 4x 160GB drives in it (I got it with only one drive and that turned out to be dead when I got it home). I get the same sort of write speed as you (I have not done read speed tests yet).

so drives clearly are not the bottleneck then, i can only think that read and write speeds are being limited by the processor speed then.

No, the drives are not the bottleneck. The bottleneck(s) is/are the RAID 5 operation (writes, building, and rebuilding) and the Networking speed. Both of which, like you, I think is a function of the speed of the processor (233Mhz CPU).

Like Phoienix32 said the bottle neck is in the cpu. Write speeds should be slower than reads. Use a FTP program to measure you speed. It elimiates some of MS Overhead. Speed transfer can be impacted by your network setup. There are some routers that have very poor performace.

If you look at all of the NAS out their all the good ones have some serious HP under the hood. Because doing XOR parirty calculations require it. My 4500 is equiped with a 2.4 ghz P4, 800FSB. My bottle nec is that my PC's are not up to the task to tax it. I am going to have to find program that can generate the file it is sending. Removing the HD (pc) form the equation.

I just did some speed test on my system using FileZilla FTP and SmartFTP. FIleZilla is 33% faster than SmartFTP, weighing in with a write speed of 15.8MB/sec substained speed. This was run over a gigabit switch. Test is in another section of the forum. http://forums.procooling.com/vbb/showthread.php?t=13765

since the processor is the bottleneck. are we able to upgrade the processor by any means?
a couple ideas that come to mind are:
using a k6 with the socket pin mod.
or using a k6 with a powerleap adapter.

can anyone tell me the SL number of the intel processor that is in there now to get the specs on the vcore iovoltage ect?

And just because I am feeling so crappy today;

Dude, there is the neat new function on forums called "SEARCH"



Sorry David, I am just not in good spirits today and I have to ask myself, "how many times have I started this topic now"? If I am out of line, just delete my post(s), I won't take it personal.

ahhh but Phoenix if YOU read that thread you'd notice i also posted in there

(we can both have fun with eachother )

digging through intels database, the 233mhz intel part had a core voltage of 2.7-2.9
the K6-2's ran at 2.2 core (ive got a stack sitting here)
thats why i suggested the powerleap device as it has built in voltage regulators to overcome this problem on regular pc's AND multiplyer hurdles on old pc's.
