Stupid, thanks for posting that link. Those numbers are interesting. The avg read of my 74GB is around 78-80MB/s so it appears there is some type of performance increase with those drives compared to mine. The RAID 0 numbers are just plain ridiculous

All review sites have it destroying everything... except SSD. The VelociRaptor can transfer twice as fast but it loses in app benchmarks. I want two 150GB versions of these for RAID0. I don't need a 600GB for my OS and apps.

To answer most of your questions: (1) a fridge cannot cool a PC (2) 64-bit OS for over 3.4GB (3) If a PCIe card fits, it should work (4) Resolution, not screen size (5) Report, not respond to Spam (6) Single-Rail/Non-Modular PSUs are not always better than Multi-Rail/Modular (7) Sequential does not matter as much as random for OS drives (8) Requirements come before hardware for servers

Duckie, thanks for the related links. This new drive is definitely out preforming my 74GB FD drive. I feel you on the 600GB for the OS. To me that's just a waste of space

reps anyway
The first partition of your drive will automatically use the beginning of the disk which is the outer rim. Using the outer rim makes for the highest sustained transfers and the shortest access times (the arm moves from the outside in).

Just create a partition at the beginning of your array.

Oh... and single platter VelicoRaptors would also outpeform the dual platter 300GB version.

Also, don't forget these benchmarks are of mostly engineering samples.. pre-first generation. Raptors in the past have gotten noticable performance increases with updated firmware. There 5-7 reversions of the old Raptors (regardless of size).

Duckie, interesting. Can the existing FD drive that I have now be updated with a newer version firmware?

Not sure... In theory, I would say yes. However, HD manufactors generally don't allow you to mess with the firmware.

Check this review of the WD740GD-00FLC0. This is the fourth revision of the 74GB 8MB version. This is an older article since the 16MB cache version later came out and I think there might be two revisions of that.

I don't think you can control where your partition starts.
1. the physical position is set during low level formation.
and can't be changed by software (at least not with desktop HDDs).
2. When I remember right from university lecture, does Windows start a (high level) partition in the middle of available "address room"

Your are very welcome to tell me if my sentences have poor grammar, or are incorrectly worded.
I enjoy learning English. ;o)

Duckie, thanks for the benchmarks. Nice to know they are almost hitting 1000 I/Os

Ronin, I'm curious. Mind sharing?
