Computer newbies: PCI-X compatible with PCI?
PCI-X compatible with PCI?
by zman1991 - 6/25/06 2:30 PMI'm searching for an SATA II PCI controller card. Adaptec has a 1420SA card that looks like a PCI. The blurb from 2 sellers indicates PCI-X/133 "compatible to PCI 32/64 bit". I want RAID 0 for the lazy man's backup of my IDE hard drives and bootability if my C drive coughs or dies. I'm using: Windows xp Pro SP 2, Asus A7N8X-E M/B, 2 GB RAM, No help from on board SATA drivers that want me to back up SATA to SATA.
RAID 0

Wrong raid level...

With Raid 0 you are splitting the data evenly between two SATA hard drives...half of your file may be on the one and half on the other. Thus if one dies you're completely screwed...you lose it all. Raid 0 is not used for backup, but performance.
If you want two SATA drives, one a duplicate of the other, you want Raid 1. However, this only solve the issue of one hard drive failing physically. If your computer gets fried in an electrical storm or you accidentally delete a file you're again out of luck...the data's gone for good.
If you want to securely backup your data you want to use a portable hard drive, flash drive, etc. That way:
1.) You have a backup even if the computer bursts into flames.
2.) You have a backup even if you're robbed.
3.) You have a backup even if you delete the file from your computer.
If you don't use an off-site backup method then you're only protecting yourself from select incidences and are still in danger of losing your data.
Hope this helps,
John
I understand ... Use RAID 1

Is it still possible to "mirror an IDE drive to an SATA? Most of my "important stuff" is on a dvd or cd - still not fire or cave in proof - but retrievable.
Looking to contact Col. Quander -old cadet from Dunbar

So what is the real purpose of RAID after all??????

I consider RAID as something best left to the IT guys who works for companies not home users, am I right? I have a computer case with 7 bays for harddrives . I dont need 7 bays!!!! The drive bays crowded out the mother board and PCI slots that I work around the most.. I consider the drive bays as space hogs!! I would like to use RAID as a backup , but there is lack of information on how to properly replace the failed drive with the other one in the RAID setup without getting wiped out.. So therefore, I avoid RAID altogether.. I dont think it is as simple as pulling out the failed drive and put in the good one simply because they are identical in RAID 1. I think there is a lot of more steps to do that. I dont think I know what the heck I am talking about... I would try RAID again when I know enough about the RAID procedure for replacing the failed drive as long as it is not a weekend long hassle..
