What Raid should I use?
Hi,
Running Targa 3000 system for several years, yes nice system but old, still on Premier 6.5, now i’m building a new system that run CS3 with Black Magic’ Decklink SD card:
– MoBo: ASUS P5K WS – Intel P35 chipset (Core 2 Duo) – Upto P4 3.8GHz; 4xDual DDR2 667 / 800/ 1066 (Max 8GB Ram); Sound 8 channel & Dual NIC Gigabit onboard; 2xPCI-Express; Raid 0,1,5,10; IEEE 1394; 6xSATA; 2xExt SATA; 3xPCI; 1066/ 1333 FSB
– Processor: Intel Core 2 Quad Q6600 – 2.4GHz/ 8MB L2 Cache/ FSB 1066MHz/ 64Bit
– Ram: 4Gb
Working on AE, PP Pro, C4d, uncompress 8 – 10 bits SD only.
– Is DecklinkSD run well with CS3 on window XP?
– What graphic card should i use, heard bad things about 8800 series?
– Is Mobo’ internal raid 0 fast and reliable enough to handle uncompress 8 – 10 bits SD or using a raid card, what raid ( raid 0, 1, 5) and what raid card should I use?
Any recommendation is appreciated.
Thanks in advanced.

I’m not exactly sure what your asking… does the internal raid allow all types of raid setups or just 0?
As for “which raid” it depends on your RAID size and your priorities…
RAID 0
Is it fast? yes. Secure? no. RAID 0 just a faster style of hard drive control often setup for more space at a higher speed. If one of the drives burns out, the entire set is lost.RAID 1
Higher number, more secure. This is a basic mirror set…. say you have 2 drives, if one of the drives goes down, your data is safe since it’s already on the other. This is not a good choice if you have a LARGE array… see below.RAID 5
Is the most secure of those 3… it “stripes” your data across all the disks in the RAID setup. IT also keeps all your data safe if one drive goes down. This is also the most common raid setup.So if you had say a hard drive array that is
4 TB total, 1 TB on each disk… if you setup raid 1 it would be fast, but you’d only have 2 TB of space since your doing an idential mirror. If you setup raid 5, you’d have 3TB total space, because of the striping you only loose the space of 1 drive in the array. (Thus why RAID 5 is the most common because most people with a RAID setup use it for LARGE amounts of space)With any raid above 1.. if any one drive does down, you can replace the broken drive and the array will “rebuild” itself. In the mean time you can still get your data off, but if another drive breaks before you fix it… you’ll loose everything. Unless you use RAID 6 (hard to find) then you can lose up to 2 drives… but again, lose 3 and your out of luck.

Thanks Tim,
– Software raid is not sufficient for video editing. So would you recommend some raid cards (hardware based raids) at reasonable price.
– Will eSATA II 3Gbits, LaCie 2big Dual (2-disk RAID) fast enough? Can I Plug this Lacie direct to Asus P5K WS Mother Board’s eSATA Back Panel I/O Ports or have to use with LaCie SATA II PCI-X/Express eSATA cards as LaCie recommend?
Thanks in advanced!

The setups above apply to all raid setups, I don’t even know why people would mess with software raids anyway.
Standard SCSI was fast enough for video editing and eSATA blows those speeds out of the water… so yeah, anything eSATA will be fast enough for editing.
If your computer comes with eSATA plugs… check to see if their 1.5 (SATA 1) or 3GB (Now called SATA 2, but double check this) speeds, if their the higher then use them. If not, get the card.
