Just playing around with CCD and 2 Atlas's on a P120 2940UW, 128MB RAM.
It kept the sys time at 80-90%, so maybe a faster CPU would help.
IOZONE writes a 512 Megabyte sequential file consisting of
8192 records which are each 65536 bytes in length.
It then reads the file. It prints the bytes-per-second
rate at which the computer can read and write files.
Writing the 512 Megabyte file, 'iozone.tmp'...42.148438 seconds
Reading the file...37.859375 seconds
IOZONE performance measurements:
12737623 bytes/second for writing the file
14180659 bytes/second for reading the file (It was over 15 on one
run).
My only observartion is that this goes against all the people telling me
that reading should be slower than writing, when it turns out inverted on
some fuji disks I have.
In any case, it's nice and fast.
As to drives, SuperCom had Quantum 4GB Atlas's 34300W (Wide) for $870,
which is a pretty good price.
