Plague’s poor man’s array

In another attempt to appease my modding urge, I’ve redone Plague again, this time adding the temporary array from the old Headcrash setup to this box. Basically, I wanted to see if I could stuff four 10,000 rpm SCSI drives into a space designed for two while maintaining tolerable case temperatures.

What I ended up doing was purchasing four wood reinforcing strip from Home Depot and doing a little bit of trimming and clipping to the case to make it fit properly.

Then I drilled two holes in the front of the case for a 120mm and an 80mm fan. The two fans blowing at 7v are sufficient enough to keep the case at ambient without sounding like a vacuum cleaner. Unfortunately, the ball-bearings on the 10k drives whine like madmen.

Here are some pics from the project:

 

Headcrash SCSI benchmarks

While reinstalling Win2k server on Headcrash, I decided to take some time to run some benchmarks against the storage subsystem to see what would make the best setup out of the hardware I had on hand.

Here are the results using SiSoft Sandra.

Here’s a test of five LVD-80 10k SCSI drives in RAID-5:

 

Here’s a test of four U-160 7200rpm SCSI   drives in RAID-0:

No real surprises here. RAID-0 beats RAID-5 and U-160 drives beat LVD-80 drives. Nice to know that SCSI RAID-0 still outperforms ATA RAID-0.
