What would you do with 4 x 74GB Raptors?

Well it would be complete pointless doing RAID 0 on a motherboard chipset controller as 2 alone will max out the bandwidth (even 2 of any modern drive will).

Interesting is that both NF4 and SIL3114 chips, or just the SIL?,

so you would RAID 0+1 then for maxing the bandwidth while keeping info secure ?

unless they the sata 2 model, have yet to see a 2 drive array do up to 300 megabytes per second. :eek:
 
Predictably Wikipedia goes into it in more depth than I can or care to at this time of night but essentially as I understand it, data is striped across two drives with the third storing parity data from which the array can be rebuilt if one of the drives fails.

Personally I'd sell two or more of the Raptors and buy a quick 7200rpm drive as backup, probably a Western Digital AAKS model as it isn't much slower but offers much more space. :)

messing ofc

yeah RAID 0+1 sounds good but arnt the raptors a tad noisey???
ive herd of people having enuff of the noise n ditching them
 
Hmmmm looked here at what RAID 5 is http://www.storagereview.com/guide2000/ref/hdd/perf/raid/levels/singleLevel5.html

seems interesting, apparently READ speeds on RAID 5 disks are Very good, but writes arnt so good, but obviously better than a single disk. Also has better fault tolerance, so could have 4 disks, 3 'seen' with 4th for parity data.

how much better this would be over 0+1 remains to be seen
 
wow.. 4 x Raptors.

i'll check out the benchmarks with 4 as Raid 0 and 2 as Raid 0.

if the performance isnt' that big of a difference, i'll use 2 of them in Raid 0 for OS for my main rig and the other 2 for OS in Raid 0 for my 2nd rig.
 
RAID5 for sure. Easily 180MB/s read. If done with hardware RAID5, can hit about 80MB-100MB/s writes (depending on controller etc).

Would be nice. If not, then RAID0+1 would do just fine.

Totally depends on the type of controller and how the controller is connected to the chipset. Most chipsets have at least 150MBps dedicated to each SATA channel, so connecting 4 fast drives isn't going to bottleneck.

They might have 150/300MBps to the controller but typically they'll max the bandwidth between the controller and elsewhere.

If you want to get the real benefit of RAID 0 with multiple drives you need a dedicated controller card with plenty of bandwidth.

raid 0, definately - you can never have enough linear transfer bandwidth :p .

How exactly the SATA chipset is wired to the system bus determines the maximum speed you'll see, most onboard these days use a single PCI-E lane so you should be good up to 250MB/s - shouldn't be a bottleneck for 4 drives considering there are certain inefficiencies and overheads regardling rotational latency and command queuing each time you add a drive.

If you have a Intel chipset with matrix RAID, you can carve up the disks into logical volumes with different RAID types, eg, RAID0 for your game installs, swap file, temp files etc, and RAID 0+1/5 for your important data. (but remember even RAID 1 or 5 is no substitute for good backups - they just prolong failure, not eliminate it)

I get between 220-300MB/s depending on which benchmark I run on my disks, which makes a vast different in loading times over a single disk.

BERLIMEY! you have 4x 15k drives in RAID 0 :eek: that must FLY iv got like 6 other harddisks for space and back up so thinkin RAID 0 out of 4 raptors for XP+vista install, and use seperate seagate drives to hold my information, will probably partition the 4drive array into 2 partitions, xp and vista

Infact I dont know what to do really, my list of current harddrives is:

4x Raptors 74b 8mb cache
2x 320gb Seagate SATA2 16mb cache .10's
1x seagate 7200.7 200gb SATA1
1x seagate 7200.9 80GB SATA2
1x Hitachi 250gb SATA2

RAID 0 the seagates? :D , nah, hehe, its all random, best sell some soon I guess

put them both in scyth hdd silencer ive got a 150 raptor in one and i cant hear my drive
