I have never done this but the first thing I'd worry about would be the drives. You say you want to avoid virtualization because of the cache issue but my understanding is that this is an implementation/configuration issue rather than a problem with virtualization per se. And you'll have the same pr...

945GC... bottom of the barrel stuff (low power efficiency).
Would a single core be enough for your needs? Passively-cooled 945GSE boards (see SPCR's review... and the first answers you got) are not that expensive.
If you're in no hurry, Intel is supposed to release the next generation in January.

I'd be interested to know what resolutions are supported through DVI? 1080p monitors are becoming common but some boards don't support that resolution (officially anyway). My googleing led me to believe that, while the Asus B202 can do 1080p (the resolution), this board can't. Could someone who's ac...

the ones at work are used in large RAID arrays that are constantly slammed with read/writes (image files ranging from small JPEGs to larger RAWs). Can you quantify "constantly slammed"?

I've got a bunch of 7200RPM 40G Samsungs in workstations that are still going strong.
In non-mobile applications, I think I've only had Seagates/Maxtors die on me recently.

Re: Backup to disk storage in a business environment

The I in RAID stands for inexpensive, your card is a sunk cost unfortunately and it doesn't sound like performance would be an issue for your application.

Am I hinting now? :-)

Re: Backup to disk storage in a business environment

1. If a backup to disk exists and the equivalent tape is off site then I don't have to have someone drive to get the tape. Backup to disk could be reduce the downtime by the time needed to get to that tape. The worst case scenario is the vault tapes are stored in couldn't be opened for a day or two...

Re: Backup to disk storage in a business environment

Since we do daily backup to tape the backup to disk is merely for convenience of not having to mount a tape to restore. [...] If the drives are big enough I'll probably just do a RAID 1 this time instead of RAID 0 and call it good. Why are you planning to use RAID at all? Either you're not telling ...

Nothing wrong with compression. Just don't count on it unless you know what you're doing or you might end up unable to backup for lack of space. Don't trust this Acronis thing blindly if you care about your data. It's good practice to try to restore ALL your data in order make sure your backup proce...

You can use SMART with software RAID.

Avoid RAID0 if you care about your data and don't rely on compression when planning backup media purchases.

Re: Looking for recommendations on 1 TB drives

performance isn't a big issue. I am mostly concerned with reliability So I doubt that performance as slow as the slower of the drives (for some operations) is going to be an issue, unless they are badly matched. I've temporarily put badly matched drives in a RAID1 array on occasion and I don't reca...

And the rationale for getting identical drives in this case is?

Different RAID setups have different requirenments.

Parity isn't magic. Though RAID1 is the gold standard, you're not taking too many chances with two or three data drives and a parity drive. But 8 data drives per parity drive and no backup? n+1 drives means your risk is x to the power of n. I don't know how low you figure x is... This proprietary sy...

I'm late but, for the record, one can use TPFanControl but you can't make it run slower than 2900 RPM except by turning it off.

Software RAID1 usually works fine if you know what you're doing. The most important thing to understand is that RAID is not a backup solution. Although it can help in some data loss scenarios, the main point of RAID1 is to save you time and effort when a drive fails. Is it worth the cost and trouble...

comparing three 5400.2 drives

I had an opportunity to buy two cheap 5400.2 (2.5'' Seagates). I thought they'd be quiet based on what I read here. I didn't intend to compare them but the difference struck me and I listened more carefully (I've got no meter that can handle such faint noises): -one of them is a 60G (one platter acc...
