RE: [OT] New pc - Question

I doubt that you will experience any performance problems with the hard
drive.

Hard drive I/O is mostly irrelevant for real time use of real time trading
software. Processor, memory, bus and graphics speeds are far more relevant.
Providing that you have enough memory and that therefore the operating
system is not paging stuff out to disk, using virtual (page) memory.

However, if you notice your hard drive light blinking much, or hear a lot of
I/O when trading, then check your memory usage via task manager or some
other tool.  If it stays below 60% usage you should be ok.  If it goes above
60% then you might want to add more RAM to your system.

In statistics, randomly occurring events that use 67% or more of the
capacity of something, whether a supermarket check out line or computer
memory, will be the start of significant event or activity clustering, and
thus of capacity problems for computer memory or hard disk capacity or
processor utilization.

Hard drive performance in some systems under some operating systems can
become a problem at 50% because of paging, fragmentation and use of
temporary files that are not usually included in storage usage measures.

Bottom line is that your system is probably ok, but you might want to add
another 500k of matching (presumably DDR) RAM to it.

.."35 MB hard drive capacity.  Two drives are better than one, above 35
gb, but
only if both are SCSI.  SCSI is faster than other choices because it
permits
simultaneous operation of multiple drives, but SCSI costs a lot more."...

HI,

I have just purchased a new machine that like this...

Windows XP pro
Ram DVD 512 (new type not SDRM or whatever it was ..)
Intel 2.4 GHZ Processor
Hard Drive Seagate NTFS 60 GB
5 x Monitors max ( 1 * AGP GForce 64 MB Dual Card , 3 x GForce PCI 32 MB
card)
CD Rom  at speed  if 7200

SO far happy, but my question is this, this is no way I will have more than
10
gig used on my 60 gig hard drive, I wanted a smaller one, but they dont make
smaller ones anymore, does having all the extra free space on the HD mean it
will be slower writing up down to the drive...50 GB free...is that a
limitation
?

Should i split them,,,,

thks in advance
