Long time lurker, first post! I recently moved and in moving discovered a dead 74gb raptor that I had long forgotten. Well, I checked the serial and low and behold I was still under warranty! Score! So I've RMA'ed the drive and will shortly receive my replacement. My company has an incentive system where I can purchase things on amazon.com with "points" well I was thinking of purchasing another 74gb raptor and setting up a Raid 0 array. I know this isn't really a huge performance boost for most things, but it IS really cool. Well here in lies the issue. The new drives are 16mb cache and the old one is of course 8mb. I'm fairly certain the setup will work, but what if any are the negative benefits of set up like this? I also have the option of a 150gb raptor, should I just go this route? Thanks in advance to all who reply.

It will still work if thats what your asking.
If I were you I would just wait until the velociraptor comes out and buy one of those

Nitro, thanks alot for your reply. I do know that they will work. I guess, my question is more, is with one drive being 8mb and the other 16mb am I negating any performance gain I'd have over a single Raptor 150gb? I am simply unsure how much the cache will affect performance, so I've come here for clarification. The velociraptor does look awesome, however...I am not paying cash for the 74gb or 150gb, I have just enough "credit" for a 150gb raptor....so those are the only options at this point. In a nutshell...Am I better off with 2 74gb's one 8mb, one 16mb cache than I would be with a single 150gb raptor?

Well if your set on buying(credit) one, just get the 150. I cant say for sure that there would be a negative performance impact or even if there was you probably would not be able to tell without running some diags to tell you so. Also your kinda comparing apples to oranges, two 74gb in Raid0 to a single drive. Also depends on Raid Controller. Just too many variables to tell you that you will see a negative performance from diff cache sizes. But if I were in your situation i would just get the 150 and then have two separate drives. Also this way you end up with more storage space.
I would go ahead and get the 150 Gig Raptor, install the OS on that one, and use the 74 gig for your swap file and data storage.
A Raid 0 setup will default to the slowest and smallest drive in the array.
The 74 gig you get in exchange will prolly be a 16 MB cache drive anyway. The 8 MB ones were an early version and may not be in stock anymore. Anyone sending in a 36 gig Raptor have been getting 74's lately.
