Most all drives have cache on the drive.

Kev,

I have never heard of a cache directly on the hard drive (Which certainly doesn't mean it doesn't exist). I have heard of a cache on the controller for the HD!
I assume that you are looking at upgrading one of the Dell Workstations, yes? If so, I highly recommend calling Dell and ordering HD's from them that are supported for that Workstation. Dell uses high quality products such as Seagate and IBM for HDs, so don't worry. The main concern is compatibility and continued support!!
The majority of Dulcian's DBs are small development databases...so you will likely never need 4x18 GB of space... 4x9 GB will suffice. But, check the pricing difference...if the price diff isn't too crazy...go with 18. You should probably go with 1 9 GB for the OS and 3 18s for the database.
Ultra Fibre SCSI...I'm not 100% on this, but I would say that these drives are optimized for external storage where Fibre Channel is used to connect the server to the storage cabinet (certainly not your case).

Hi all,

Just thought I would throw this one out there and see what all of you hot
shots think. I am going to rebuild a server into a DB Server. Currently it has IDE drives in there and obviously I am not going to be using those. So I need to invest in some new SCSI drives. Here's what I had in mind:

Either 4 X 9.2 Gig 10K RPM with 2mb Cache OR 4 X 18.4 GIG 10K with 4MB cache

I was initially leaning towards the 9 gigs to save on cost, however someone pointed out that 18 would be a better idea for growth down the line. Also I want to keep them all of the same size in case one goes down then I may have room on another.

What are your thoughts on this? Does anyone know what "ultra fibre scsi"
means? Does anyone recommend brands to stear clear of? I know that Seagate is a pretty good name, but I can't find any in Ultra 2? Anyone know if Hitachi is a good name?

Thanks in advance.
