Raid 0 vs 10000rpm drives

[marscay]

imo raid 0 valociraptor just get the smaller ones sdd still suck and your p nly paying to help them get developed

velociraptor is dinosaur technology, at £400 (2x300gb) it doesn't have SSD like access times nor impressive STR for the money in my eyes.

400 notes buys a lot of quality single platter drives for insanse STR with enough left over for a good SSD on the OS.......or even an older Raptor or 2 for the OS + some single platter drives. Vraptor just seem insanely expensive for some more STR and more or less the same access times as the older models.

i get the feeling they're not selling too well, doesn't seem to be much talk about them in a lot forums.

marscay, there are 74GB and 150GB Velociraptors out now, £102 and £127, so it would be £204 for raid0 (2*74GB).

velociraptor is dinosaur technology,

Pretty impressive when Dinosaur Technology crushes the competition

 

[clocka]

dinosaurs rule the world! 120mb/s is nothing to scoff at, neither is 7ms access times, its also quieter than nearly all 3.5" drives. I wouldnt mind 1, but at £67 more than a samsung f1 320gb it just doesnt justify it.

Does a Velo really make much difference during normal usage (i.e. surfing and gaming) or does it only really kick in when you start moving RAR's. etc?

 

[clocka]

gaming is a big improvement due to the low seek times, it loads games quicker and loads windows quicker.

Raid 0 is great when you're doing sequential reads/writes (i.e. working with very large files). At the moment you throw random accesses at it (i.e. normal usage) the performance stops looking so stellar and the drive will be spending more time moving the heads than reading - and RAID 0 does nothing for your access times.

My opinion is that in the desktop world RAID 0 is simply not worth it, unless you need it to work with very large files. Otherwise Go for a VRaptor for your OS and installs and a big cheap drive for storage (or maybe two in RAID 1)

For normal use, and indeed almost all non-server use you get a small but just about noticeable improvement to the speed of opening applications due to the lower access times; it makes things feel a little quicker but I know I don't miss it when using 7200rpm drives. Games load a couple of seconds quicker but you won't notice it for them.
SSD's have just about instant access times so you can really feel a difference with those.

gaming is a big improvement due to the low seek times, it loads games quicker and loads windows quicker.

I just found some new drivers for my onboard Intel P35: ICH9R ( which im not sure is sata2? ).
Vista32, 4x Hitachi 80gig 7200 ( would sell to interested museum lol )
Comparison driver results below which are very interesting:

Interesting how now the performance fades off as each test 'winds-on' with the new drivers & whats with the burst rate now lol.

Its looking like the more drives the MUCH better things go (except access time).

Ps. a question: how does access time help things?

 

[helmutcheese]

The ICH9 is SATA 300 (no such hardware thing as SATA2).

 

[juno_first]

Ahh, I've just googled SATA2 specs & SATA1 is <150mb/se & SATA2 is <300mb/sec.

I guess if you're already reaching 300mb/sec then more drives on the array wont help much?

Maybe when solid state drives reach 300mb/sec then they'll make SATA2 hard-drives redundant, depending on price of course?

Then theres improving the data bus speed between the drives & system.

and on and on and ariston...

 

[helmutcheese]

No, SATA2 is a body or people nothing to do with any hardware.

 

[psychas]

but then if you raid 10k raptors it is even more faster

 

[jrwagh333]

Is it possible to have this setup...

1 VR for windows and office etc

and 2 WD 640GB drives in RAID-0 for storage?

If so how would i go about setting this up?

 

[clocka]

yes it is possible, you just attach all 3 drives to motherboard, select raid option in bios, then press ctrl+I after detecting the dvdrw etc and select the 2 drives you want in raid0, create the raid0 array and its done, just install xp/vista on the velociraptor like normal and when in windows install intel matrix manager to install the raid drivers.

 

[sibeer]

Just hope you aren't planning on storing anything on there that isn't going to be backed up

 

[StevenG]

RAID0 should NOT be used for storage.. ever! its just not worth it...

yeah you get 2 discs joined together.. but just put your files on either disc for security..

i had my raid array fail once already so bought some TB drives for storage.

*someone also mentioned me only using 200gb of the 750gb i have available. this is so that my files stay on the fastest part of the drive.

un-rar'ing fils on these raid arrays is amazingly fast so anyone working with large files its great. i have seen big improvements at the desktop. applications open extremely quick and load times in games is a little faster but nothign major.

there are benefits and for the price i paid for 3 reletivley low end drives i think the performance is great.

Don't Raid 0 for storgage if one drive fails your buggerd and lose your data

 

[helmutcheese]

That cause n00bs don't have a back up.

EVERYONE should have a backup be it Single Drive use or Raid.

Used Raid0 for 5 years and not lost 1 bit of Data ever inc crashing PC's 1000'sX due to OC'ing, that old tale is as old as the hills.

 

[Stonedofmoo]

Aye I've never once had a RAID0 failure. It's not that it cannot happen, it's just that I've always invested in Enterprise class drives which are built to be more reliable. Thats drives like the Raptors and RE2/RE3 series.
