how come u dun understand wht those color means?
green = eco friendly = less power = slower

You misunderstand him. He's not admonishing you. It's just not that easy to explain. Green means power saving but that's at the expense of performance. WD black is good but price needs to be considered. To learn more about the difference, you shall need to google.

Kindly read this earlier post. It was somewhat of a revelation for me. Review was about Seagates but note how WD performed. Go for WD Blue 640GB. It gives the best bang for buck

When I last checked, some shops were selling for around RM220 last week.

I got mine from Viewnet 10 days ago. Try giving them a call.

If you're including courier charges, that may explain it. It's listed as RM214 on their online price list. Don't you have any pc shops in Ipoh?

AFAIK, SV35 isn't really an Enterprise version disk. It's a drive, designed specifically for digital video surveillance recording. They have large caches & are designed to be located in drive cases that may get quite warm (70C). Not really meant for general purpose computing.

Found you some data about SV drives.

Shouldn't be a problem. If you dedicate it for storage and not operate it 24/7 the lifespan should be pretty long. I'm very confident of current generation of HDDs lasting 5 years of continuous use. The good thing is, when it is about to fail you should see the symptoms like abnormal operation noise (clicking, etc). Turn on SMART and keep a SMART utility running to keep tabs on the error rates.

If you value reliability and data retention, forget about RAID 0 unless you have another set of disks dedicated for performance operation. RAID 1 is good for mirroring. If you need performance and reliability then you may consider RAID 5 but that's pretty CPU intensive unless you have a dedicated controller for that. If RAID is not your taste, then you're fine with a single drive. Do remember that you need a stable system to begin with. Unstable SATA/IDE drivers can cause data corruption.

I bought a WD Caviar Black 1TB - the same one that jimmylim85 asked about - and it developed read errors within a week. Fortunately, it was in a RAID1 with a Samsung 1TB (I deliberately bought a different make/model to rule out common causes of failure). Moral of the story - no matter what people tell you, never be blindly confident in single drives. Always have your data on RAID-1 (or other redundant config) and/or have a backup.

This statement belongs to 1999. RAID-5 is laughably CPU-intensive today. A modern CPU can handle thousands of MB/s of RAID5 XORs. That said, there are other good reasons to get a dedicated RAID controller - e.g. for the battery backup and port counts.

Very true.

ya ya,. quickly got the answer from my fren "Google" 

Green: Slowest, quietest, lowest power

Blue: Standard drive

Black: Performance tuned, faster, potentially noisier and more power hungry

I would choose WD 1TB C.Black...Better performance or speed is required for high capacity hdd like 1tb...
