drive configuration on new sql server 2005 box?

I have a new dell 2850 server with 4 146gb drives attached to a raid 5
controller. I would like to know how I should setup the drives for
installation of server 2003 std os and sql server 2005. This server is going
to be a dedicated sql server to serve databases for web applications.
Thanks and let me know if I should supply any additional info.

In BOL, index tab, type NTFS, see note.
SQL Server magazine had a good article on hardware for SQL Server . I can't
post it as it is for subscribers only
http://www.windowsitpro.com/SQLServer/Article/ArticleID/46492/46492.html#
In the nutshell, system = RAID1, logs = RAID1, data = case when cash poor
then RAID5 else RAID10 end.

OS should always stay on RAID 1. No Exceptions should be made here.
For SQL Data, You can use RAID 5 if you wish to though RAID 5 is not the
best solution. For Faster Read\Write RAID 10 is the best solution but then it
has a cost attached to its performance.
Since you have 4x146 GB Drives on the machine, I would recommend that buy
another couple of drives identical in size and host RAID 1 on it and use it
for OS.
For other 4 drives set up RAID 5 and use them for SQL data and log.
Hope this helps.

Since we're kind of tight on funds, I'm going to setup the drives as follows:
1 separate 36 gb drive for OS and SQL Server program install.
1 separate 146 gb drive for Tlogs.
3 146 gb disks in RAID 5 array for data.
Does this look acceptable? Not the best, but acceptable?

If you use only one drive for OS, if the drive fails, everything is gone.
Therefore, you must, must, and must use RAID 1 for OS which will involve a
minimum of 2 drives.
Here is what you need to remember:
RAID 1 requires at least 2 drives.
Raid 5 requires at least 3 drives.
If you use only 1 drive as you are mentionining, you can only build RAID 0
on it which gives no protection against data recovery.
I would say based on your server since it's not on SAN, use 2 drives for
RAID 1 and set up OS on it and use 4 drives for RAID 5 and set up SQL Data on
it. SQL Binaries can say on the same RAID Volume where OS resides.
I hope this helps.

Where would the transaction logs go? On the same RAID volume with the OS?

4 146 gb drives in RAID 5 container partitioned as C:\ (30 gb) and D:\
(remainder of space)
Windows Server 2003 w/ SP1 installed on C:\ partition
nothing else installed as yet
I'm trying to figure out if this setup is ok and then just add an additional
RAID 1 array for the transaction logs?
I appreciate your assistance.

hardware we can afford to purchase.

In the future I would order smaller drives and more of them. Lets say that
you have the 4 of 146s If you have the drive bays how about 10 72's. Raid
this in pairs as RAID 1. This way you have 5 drive letters where you can
table partition your storage for a better performance.
I know this sounds odd. But I have found that smaller faster drives =better read times.

It's not the drive size as such that makes it faster but the number of
heads available for operation. Having a RAID with 10 146GB disks might
not be slower than a RAID with 10 72 GB disk. Of course there can be
various differences in design (number of plates etc.) but I think that
will makes a difference that is mostly theoretically.
The general rule of thumb is that you should get as many and as fast
disks as possible.
To get back on topic, I agree that a SQL server with only 4 disks is a
no Win situation in many cases. Another possibility could be to setup 2
RAID 1 arrays, but no matter how you configure it with OS, logfiles and
datafiles, you won't have the optimal setup.
In your case where you need it for a web application, it might be ok
though, but it depends on your need of recovery and availability on the
web server. We have a SQL server that host the database for one of our
web applications and here we restore a new database each night. The
database is also only used for read operations. On this server we run a
RAID1 for OS and a RAID 5 that contains both logfiles and datafiles. I'd
never do this on a server with critical data, but in this case where we
just can restore a new database it doesn't matter. Maybe your setup is
something similar and in that case I think it could be justified to put
log and data files on the same RAID.
