BF2S Forums Difference Between Raid 0 and Raid 1?

Raid 0 is "striped" data storage, which means that the data is wrote to and read from both hard drives at the same time. (Good for gaming load times.)

Raid 1 is "mirrored" data storage, which means that data is written to one hard drive and then copied to the second. (Bad for gaming load times, good for data protection if one hard drive fails.)

The best is Raid 10 which is both Raid 0 and Raid 1 put together, the only bad thing is that you have to have at least 4 hard drives...

what they said.

for ur overclocking... it may damage ur pc...

it runs at 1.8ghz coz the multiplier is 9 and HTT is at 200. bump ur HTT/ FSB to 250 then u get 2250mhz. but u need better  cooling.

People use Raptors because they are GOOD hard drives. (10,000 RPM & SATA)

I'm still waiting for a 15,000 RPM SATAII...

+1 karma for you all thanks for the help.

This brings me to my final question in the quest of suping up my computer:

Will Raptor SATA work on my SATA2 port? If not, can I have a RELIABLE hard drive that I can buy two of for a RAID setup?

Good replies guys... I have a raptor 10k and it rocks...

OK, for those who need graphics instead of words, here's a page that I have used many times on many boards to explain what RAID is and how all the different RAID setups work:

This is just an awesome tool, tech folks should all bookmark it, it makes it easier for clients to visualize what is kind of an abstract idea.

Next, why does everyone talk about raptors? Well, lets see. If you look at a HD as a CD, with data spread out in concentric circles, then the faster that drive spins, the faster you can access your data. Drives in modern CONSUMER computers spin at 4200rpm (mostly laptops), 5400rpm, 7200rpm, and 10,000rpm. The raptors are special because they are the only consumer drives that spin at 10K rpm's.

If you get into the server/workstation market, there is another interface called SCSI (this is different than the IDE and ATA drives found in consumer machines) that has drives that spin at speeds of up to 15,000 rpm's.The problem with these drives is their cost (a Hitachi 147GB 15K SCSI drive costs $700, compared to a Hitachi 160GB 7200rpm SATA drive that costs $60).

So, the sum total of the raptor glory is that they spin faster, so they can access data faster, and load the game quicker. In other words, your geek penis is larger if you're running a raptor.

Your final question deals with reliability. Yes, SATA2 has backwards compatability (as well as those tiny little cables. I look forward to the death of ribbon cables). If you're looking for performance AND security, what I suggest is a 74GB raptor for your system drive ($170) and then a couple of identical large-capacity drives that you can run in RAID 1 for security (2 Hitachi 500GB 7200rpm drives with 16MB caches for $250 each).

Let me know if you have any other questions. And good luck.

I'm not sure if this has been mentioned, but your other alternative to RAID is SCI drives. People tend to think that raptors are overpriced drives. In reality they are not with comparable performance of SCI at a fraction of the price.

There is alot of great SATA 3.0/gbs drives out there that are alot cheaper than raptors, and still offer great performance. I think I paid around $120 for 2 WD 160 gig drives for my storage. I had the money and wanted to build a killer system, so I'm using 2 raptor 74s as my system drive.

For gaming, use nothing but a raid 0. Raid 1 is slower than using a single raptor. If you are concerned about your data, then run backups on a second hard drive or DVD if you have to.

I personally, wounldn't use any other type of drive but Western Digital. Others have good experiences with other brands, but I've never had a hard drive fail and they were all WD. I even have some drives in an old 466 that are still pluging away.

Close but no cigar!

RAID 0 is concatination which is using multiple physical drives as a single logical drive. This can be either using a second/third/etc drive then the first one reaches capacity or striped data where data is written across all disks in parallell. Its very fast for both reads and writes but if a single drive fails, you loose all the data.

RAID 1 is mirroring where the same data is written to both disks at once. It means you are safe from drive failures but its slower for reads and writes than RAIS 0.

Also, the drive architecture makes a difference IDE and SATA drives using the systems CPU to control them but are very fast for systrained reads/writes. SCSI drives are more expensive and have dedicated controller to handle them. As they are designed for multiple writes at the same time the offer better read/write performance for servers but generally worse for desktops.

However, hard drive subsystems won't make a hell of a lot of difference to BF2 other than making the load slightly faster. Get a decent CPU/GPU if you want things to fly.
