Understanding RAID - Page 2

post #11 of 23
I find RAID0 to be perfect. Don't tell me it doesn't have an effect. Windows boots very fast, PDF's load fast, Outlook Express loads fast, and Word / Excel files all load noticeably faster.

RAID1 is a waist of time for a home user though. Just get a good back up harddrive or use Vista's excellent backup features.

RAID0 definitely has an affect on single user. However, is it ever double performance? No.

It doubles I/O's and read / writes. I guess it all depends on the quality of the RAID controller. With a ARC-1210 you will get double everything. (minus latencies)

In real world applications, can you say load times are actually reduced by half?

Latencies plus overhead.

May not be half, but it is definately faster.

Here's the deal.

RAID offers cheap performance.

2 x 250GB HDD
= $139.98
1 x 500GB HDD = $149.99

You can get 2 smaller HDD for similar prices as the single larger drive and get more performance for it.

Even if it isn't double, it is free performance. Why wouldn't you get the two smaller drives?

It's funny, if people bought a second card that doubled their FPS no one would say a thing, even though most people only use their GFX a FRACTION of the time they're on their computer.

It doubles read performance. When it comes to games, most companies don't think about RAID. They think about hard drive space(part of the reason most games - even ones on DVD - still have super poor quality cinematics).

Game developers come up with these neat, tightly zipped texture formats, which take insane CPUs to decompress. So while your HDs can deliver 130MB/sec, your CPU can only decode 35MB/sec of the textures.

The one game that defies this is BF2142. I think they must store the textures uncompressed, or something.

I'm not so sure about that one Kramy. Not about the compression exactly but more about how you think that your CPU can only decompress that slowly. I'm not saying you're wrong but if you really look at the textures in games they aren't very pretty for for most part and what I feel need the most attention... to hell with all these goddamn lighting effects and DX10... make the textures look REAL for fricks sake. /rant

Now that I think about it, maybe that only serves to prove your point more as, compressed textures would theoretically look worse... similar to how compressed sound sounds worse.

Though I'm not sure where exactly you get the idea that BF doesn't have this.. (single DVD-ROM just like all the other games.) Then again, I am always in the map first in BF2142...

I will beat you.

I am going to load my BF2142 user profile into my memory as well as maps as part of a system config.

If someone wants to work RAID into their budget then more power to them. RAID 0 has given me much more of a boost in loading times than 1 second. Honestly, from the quotes alone this guy sounds like someone trying to justify why not to get a RAID setup because they cannot afford the number of drives necessary.

A 1 second difference? So you're saying that by moving from 70MB/s average read to 140MB/s that I only gain one second in loading? Um, no.
