SATA-raid controller card

Hi,

as I'm going to buy new hard drives to my old computer I thought, why not go with SATA. Sure it costs a little more but not that much.
My mainboard I have currently is an Epox 8k7a+, so in order to run SATA I have to buy a SATA-controller card. Two brands pops up in my head, Promise and Highpoint (3ware is not an option since I'm not rich).

This is what I found, Highpoint's version being most popular in the stores here in Sweden.
- "HIGHPOINT ROCKETRAID 1540 4-CHANNEL S-ATA RAID PCI"
- "PROMISE SATA150 TX4 S-ATA/IDE CONTROLLER 4-PORT"

My requirements are:
- 4 ports
- Can run in either 33MHz or 66MHz
- Raid 0, 1, a combination of those (raid0 being mirrored, 0+1?)
- Two disks running raid0 and another two running raid1. Preferably if one pair would be i.e. Seagate and another pair Western Digital's Raptor
- Hotswapping

A little off topic but when the 64k CPU's will come, what will change on the mainboard? Will it run 66MHz or something better? Maybe I should wait for that if I'm going to buy a new computer then?... just maybe

Ok, now when that's settled, back to topic.
I contacted Highpoint's support and one of the question was about hotswapping. Got an answer that I did not fully understand since my english is not the very best.

"You cant access the file on the hot-plugged hard disk, our current driver only support add the hot-plugged hard disk into broken array to rebuild. We are working the new driver for supporting it."

So I asked them what would happen if my boot disks were running at raid1 and what would happen if one hard drive would crash. I got this:

"When your one of the RAID1 went down, you can hot-swap a hard disk to the RocketRAID 1540 without shut down. And you can add the how-swap hard disk to the broken RAID1 and rebuild it."

Now, doesn't these two answers tell you a different story?
When one hard disk crashes I would like my system to still be online, using the computer as usual but when I exchange the broken hard disk with a new one, I want the array to be rebuilt, having my information safe from being lost. This is hotswapping, right?

I found the Promise card at one of the biggest online computer hardware store in Sweden, that mainly have companies as their customer.

Which card should I buy? If not any of these two, then what else do you recommend?
(new hard disks would be either seagate or western digital, leans towards seagate because of their silent drives, running watercooled system)

Thanks a lot!
 
It depends on what your first question was.

I believe they are saying that you can't hot swap a drive anytime you want unless its in a raid1 configuration. In which case you pull the bad disk and put in a new one and the software will rebuild.

You can't hotswap a raid0 configuration.
 
well, duh, I know that 😉

Question was about hotswapping raid 1 and 5.

I've actually found some test on SATA controllers @ Tom's hardware so I'm gonna read that one, see if it helps my decision 🙂

Thanks for replying though!
 
Come visit me and I'll give you a whole pack of cookies and a cup of coffee 😉

I've never heard of LSI though, but noticed a few users in the US are using them?
Dunno if they are even available in stores here. Checking tomorrow, so sleepy

thanks for the tip!
