Can anybody recommend an inexpensive PCI RAID controller card for RAID-1 that will play OK with NASLite-2.
I have set it up on an old (1998) Gateway G6-350 using a Highpoint Technologies RAID Card (HPT370/372) which I believe is not supported by NASLite-2. Tried to set RAID-1 but I get 2 separate disks? Must be PCI and support PATA disks.

Look for 3ware 7xxx cards on ebay. The 7xxx are pata so those will do what you want.

I have used an LSI MegaRAID i4 successfully - it is a 32-bit PCI card which can be used with up to 8 PATA HDDs.

Thanks dimension and Nick C. I do have the hardware guide , just wanted real-life recommendation.
Don't seem to be able to buy PCI/PATA RAID cards new anymore. It's all new-fangled PCIe/SATA II etc. etc...
So I'm looking on ebay UK (I'm in Dublin, Ireland).

Supplementary question:
I came across a PCI/PATA card from a company called 'Lindy'. It was a Ultra ATA-133 Card, Low Profile Option, RAID Function, PCI. However I noticed this;
"For HDD up to 250GB and single partitions over 128GB"
Is this common. Do some RAID cards, independently of the BIOS and/or operating system, impose hard disk size upper limits?
I'd appreciate a comment on this...

I have bought all of the hardware RAID cards that I have had from eBay sellers (6 cards in total).

The LSI MegaRAID i4 card had a 137GB (128GiB) drive size limit when I first bought it but I reflashed the firmware to version N661 and it works perfectly with large drives in NASLite-2.

Be *very* aware however that not all cards that claim to be RAID are actually hardware RAID - some require main CPU support through drivers that require to be installed into the O/S.

Thanks for that.
I'm looking at a 3ware 750-4 card which is true RAID I believe.
I downloaded the manual and found the following;
Note: The current limitation is 2 TB for any physical
or logical unit. If you attempt to create an array over 2
TB the BIOS will display the following message:
“The amount of disk space available exceeds the maximum
allowable capacity. The array capacity will be limited
to 2 TB.”

Three questions;
i. What does this mean? Can I put in 3 X 1TB drives in RAID-5 for a 2TB array to be visible, or is this counted as 3GB?
ii. I thought NASLite-2 overrode and upper hard disk size limitations giving me complete freedom to use very big hard disks?
iii. Is there such a thing as a 1TB PATA drive? Where did PATA drive size development stop at? Do you have to go SATA to get 750 GB -1TB drives?

Also:
iv. Could the 3ware 750-4 be flashed to make it cope with a bigger array?
v. I've seen PATA to SATA converter cards somewhere. Anybody have any experience with these? Would they play nice with NASLite-2?
Thanks in advance.

I am running the Adaptec 21610SA in my server at present. When I offered it 4 x 750GB it would only offer me RAID10(!) of 1.5TB. I think that 3 x 1TB would allow you to create a RAID5 of 2TB.

It is extremely unlikely that products this old will have a new firmware released to cope with >2TB arrays - the manufacturer would rather sell you a newer product (this gleaned from reading between the lines of a tech support query I raised with Adaptec with respect to the 4 x 750GB "problem" I was having).

You could have a RAID5 4 x 500GB PATA array on a 7500-4 which would give you a 1500GB array. Alternatively, look for a 8500-? card (SATA) - I had both an 8500-12 and an 8506-12 before I plumped for my 21610SA. This card would also suffer from the 2TB array limit, but it would support the 1TB SATA drives that you seem to want to use.
