 Hello !

I am new here,and It's nice for me to join your community!Yes

I am facing a slight problem here.....I have a computer with an ASUS motherboard that supports RAID,and there is an AMD 6400+ Processor on board.I want to use a very speedy hard disk setup.

So,I was wondering, would it be better to use 2 VelociRaptors of 150GB Each (In Raid-0 Of Course),or

2 x 73GB 15k Ultra 320 SCSI LVD (68pin) In Raid-0? (Don't want to use SAS,because is over my budget....)

Which configuration of the above is faster?

And something else that has to do with Raid: How many kbytes should the stripe size be?

Thanks A Million!!!Yes

 

May The Force Be With Us!

The SCSI might be a bit faster, but I would still recommend the Raptor drivers. They are very fast and have twice the space.

I'm not sure what the fastest stripe size would be.

Well Bob, I Finally Tested what You said to me. Big Smile

I got Both the SCSI and the VelociRaptors! (The SCSI were given to me temporary by a Friend)

Here Are the numbers: (Read Performance With Sisoftware Sandra Lite On Windows Vista x64) Yes

SCSI: 97 MB/s Sustained Sad

VelociRaptor Raid 0: 185 MB/s Sustained, And 232 MB/s Burst! Wow! Surprise

Please keep in mind that the VelociRaptors that I used Were Model No:WD1500HLFS and the only difference with the previous model (WD1500GLFS) is the outside cooling system of the disk.

By The Way, The Stripe Size was automatically set by the raid controller of the Motherboard to 64K.

Thank You Very Much For Your Big Help! Yes

.....I am Starting to Believe that those Drives are able to go head-to-head with Seagate Cheetah 15K.5 Drives (which have Sustained Speed of 135 MB/s In Non-Raid operation, from what I have Heard)....Huh?

Hi,

I'd recommend the two Velociraptors as they're the best value and performance for your money.Smile

Those numbers don't seem right to me, what U320 SCSI controller did you test with?

I have used Adaptec 29320A-R With HostRAID.

Unfortunatery My Friend,The SCSI time has passed on,and the Ultra 320 SCSI LVD with 85 MB/s tranfer rates in non-RAID,is left behind...Sad

I am a SCSI fan myself,and I am very disappointed about that.....Sad

 

But SAS Is Here,And Is Un-beatable!!!  Yes      (Too expensive though....)No

 

Imagine that there are 2 disks rotating at 15k rpm, have a 3,5 inch form factor and lower capacity (so they have lower data density).All the data transfer is being done by a PCI controller...Hmm

And imagine again that are 2 disks rotating at 10k rpm, have a 2.5 inch form factor, higher capacity (so they have much higher data density) and all the tranfer is being done without any PCI controller interfearing.From the motherboard to the hard disk, and vice-versa....... And above all....Newest Technology! Smile

 

There is some difference,right? Wink

bob_on_the_cob:

No problem. Wow I didn't know there would be that much of a speed difference.

 

 You guys are just making me slobber and cry with envy but in a good way.Im really looking forward to getting up to the speed and hardware some of you guys are blessed with.Im glad some of you have the means to aquire the hardware you have because it just sounds like a lot of fun.Maybe Santa will keep me in mind this year and hook me up with a Raptor and a 9800 to go along with it that would make my 2 days of this month the best seeing how my Birthday is the day before Christmas. Not likely to happen but it doesnt hurt to dream does it.The most important thing to me is my kids get a little something for Christmas from me unfortunately I,ve been so financially stressed, I havent bought them or havent been able to in the last 2 years, and that makes me feel bad and sucks too! Their getting older and everyone says they,ll understand but Its me that has a problem with it!Just want to give them something you know.Any how later I,ll work my way up to it!Yes

 

PS When I get there then I,ll glady flash some numbers at you guys, course by then ya,ll be flashing those i7,s  and the Asus,s newest hot rods but that,ll be fine! Lets go get a cold one,HUH LOL!!!Beer
