>From what I've seen there's no real significant speed advantage to going over 8MB Cache on the drives. But the real answer lies in what the expected throughput is based on the user demand and system overhead.
For my purposes, I ended up dropping SATA altogether for SCSI because my test run showed that the SATA drive array became bogged down during heavy Database related operations -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Charles Lockhart Sent: Thursday, January 20, 2005 11:48 AM To: LUAU Subject: [LUAU] off topic: performance question Hiya, quick question to anyone who has the interest to answer: We ordered a NAS, raid 5 system based on 3ware dual opteron (1.8Ghz) boxes running RH7.3 and CyberNAS software. We ordered 20 SATA 250GB drives with 16MB caches for it. What we got was 20 SATA 250GB drives with 8MB caches. And we're trying to figure out if the impact on throughput is worth several months of waiting for the other drives to come in, and possibly having to pay out a bit more money. I don't have any experience with this, was wondering if anyone on LUAU has a reccomendation?
