Very nice, Trike. Is that burst speed a bug? How are you getting?

My drives are quite old. This system has been up since 11/05. Win XP Pro SP2. Clean system and benchies havn't changed at all I think.

Ran these tests yesterday.

Raid 0 - Nvidia nF4 Stripe 153 Gb; 4Kb cluster size

I've got a few questions. Are 500 Mb/s read speeds or bursts useless in SATA drives? Or is that only when you're transfering to another port/interface? I realize a SATA I drive can only receive 150 Mb/s.

The more drives you add in RAID 0, what happens to the average seek time? It's reduced right? And why are some peoples graphs straight all the way across? I know that's better than the slope. That means they can read larger files faster. . .? Why? Better access, latency times?

v3.0.4.0/ 4 x raptor

my c:\ drive,

**ShaunO** · 07-28-2007, 07:59 PM

2x 36GB Raptors in RAID0 - very nice to those of you getting sub 10ms access times on 7200RPM drives.

Shaun.

Write back cache set to write through.

**Rol-Co** · 10-01-2007, 02:21 PM

2x Seagate 15k rpm U320 raid config on a lsi megaraid u320-2E controller pci-E
at a p5k-E board

direct i/o andr write trough

think this must be faster .....or not?
first time scsi so some difficulty's

**[XC]Atomicpineapple** · 10-09-2007, 02:43 AM

4X 36GB 16MB Cache Raptors on a Dell PERC 5/i controller. Would have thought it'd have been faster than this.

**Csyppa** · 10-11-2007, 11:10 AM

160GB Seagate Barracuda:

**[XC] Synthetickiller** · 10-12-2007, 01:52 PM

Look at my sig to see what these HDDs are running on. ICH9 chip set btw....

Pure Speed vs Size & Speed:

150 gig Raptor:

750 gig WD Cavair:

I hope this gives someone a good comparison of both of WDs top drives.

**~~Pete~~** · 10-12-2007, 02:25 PM

2x 36GB 8MB catch WD Raptors RAID0 ICH9r chipset, drivers were built in my XP disc i made

I have 2 more on the way to run 4 in total in RAID0 via the ICH9r chipset

**Xcel** · 10-13-2007, 02:39 AM

3x Barracudas 7200.10 320GB with one 300GB Raid0 slice stripe size 64kb and the rest, 400GB in Raid5 stripe size 128kb, P5B DLX ICH8r

**~~Pete~~** · 10-15-2007, 02:20 PM

4 WD Raptors 36GB 8MB catch, RAID0 32K strip, XP Pro SP2, Directly on the ICH9R

**Hachi_Roku** · 10-18-2007, 12:32 PM

unless i've missed some settings or stripe size then nvidia raid sucks (as i already predicted). install was easy tho only took few mins from bios.

3x Seagate 7200.10 500gb
1x WD 500gb
9.92 driver
64kb stripe size
no e-sata used
Vista x64

**Mad_Man** · 10-18-2007, 12:52 PM

somethings bad... i got 133MB/s with TWO 7200.10 on nVidia raid... under Vista too.

**Mad_Man** · 10-18-2007, 12:53 PM

oh, wait, its raid-5, then its ok...
if i were you, i would use 2 of the seagates in raid 0 + the other seagate+WD in raid-1 for backups...

tried 0+1 and saw no real difference with nvidia software raid.

3x Seagate 7200.10 500gb
1x WD 500gb
9.92 driver
Vista x64
Evga 680i
Q6600 @3.6 450fsb
Ballistix 8500 @600 54410 (2:3)
all settings the same as above

without raid card i might as well go raid 5 for additional space as theirs no performance gain showing in this benchmark.

**Sgt_Strider** · 10-18-2007, 08:15 PM

I'm just wondering what is the difference of using the Intel RAID configuration and a dedicated RAID card? I want to use RAID 0, but there's no data protection in the event the RAID array fails. How's RAID 1 speed when compared to a single drive setup?

**Hachi_Roku** · 10-19-2007, 07:02 PM

finally got time to mess around with raid stripe size on 680i and 3x Seagate 7200.10 500gb and WD 500gb drives.

raid 0+1: 2x Seagate for raid 0, other hdd's for +1(mirror).

32kb: 32kb was the fastest on the 680i as seen in pic on left.
4/8kb: averaged around 25-35 mb/s respectively.
16kb: averaged 50-60mb/s
64kb: averaged 85~mb/s as seen in pics posted earlier
128kb: was pretty much the same as 64kb averaging around 85mb/s

raid 5: didn't test as much on raid 5 as there was the inherent raid 5 write penalty killing write speeds

averaging copy from single hdd to raid 5 array was 25-28mb/s. read on the other hand was very good @50~mb/s (which was the fastest the single hdd could do copy)

64kb: did an average of 85mb/s as seen in above posts (still with pitiful write speeds)
32kb: close to the same as 64kb
16kb: is the golden as far as tested with an average of 97.6mb/s with a maximum of 118mb/s, pic on right

if i misinterprate any settings let me know

**tiro_uspsss** · 10-19-2007, 08:51 PM

here are mine (as per drives connected to main rig in sig)

**tiro_uspsss** · 10-19-2007, 10:24 PM

the 36GB Raptor & i-RAM have NTFS & default allocation size unit
Raptor36 is 22.57/34.4 GB full
i-RAM is 3.75/3.98 GB full

the RAID0 array (consisting of 2x RaptorX) is 8K stripe size
the RAID0 is 16/278 GB full

for anyone with a Gigabyte i-RAM connected to a ULi-M1575 SATA, i found that *WITH* drivers installed (vs2.20) that my HDTune results for i-RAM would increase the max MB/s by about 3MB/s, it would decrease min MB/s by about 10MB/s, & it would also INCREASE access time to approx. ~ 0.2-0.4ms (up from 0.0

) - so obviously i opted NOT to install the ULi drivers

RAID 1 is the same speed as a single HDD, just gives you a total and instantly updating backup of the 1st disk. If you want speed and data protection go with RAID-5. With RAID 5 if a disk goes down you can insert a spare drive and rebuild the array with no data loss. Theres also RAID 0+1 or 10, take 2 sets of drives in RAID 1 (for data backup) and put the 2 sets in RAID 0 (for speed). Performance varys with southbridge. I got 155MB/sec with 4 raptors on the Intel ESB2 southbridge but nearly 200MB/sec on a Dell PERC 5/i controller card. Not being a storage guru I may well ahve missed a vital spetting o nthe ESB2 RAID though.
