Post Hard disk transfer rates

every drive is different men. F1's work give that sort of graph.

but it should be smooth or it means its bloody slow because its dropping speed every few seconds..seems the F1 really suckz cause my HD250HJ doesnt do this

F1's are great. But mostly the 334GB per platter drives show the true awesomeness of F1's.

XP ne. Can't you see that from the screenshot?
Anyway, the "mode" will not change the transfer rate graph.

I still can't believe how the 250HJ beats the 252HJ

could be the xp wallaper..


i thought native SATA mode gets higher transfer rate? isnt it? A friend told me tht XP simulates SATA as default and it couldnt achive actual speeds of the HDDs??

Native SATA mode (i.e. AHCI) brings two things to the party:
1. NCQ, which increases the throughput of the disk, not the raw sequential read/write speeds.
2. Hot swapping.

This is mine..

What's about mine?

 

[Aragorn]

thnx..!!!

 

[psyche]

Finally RAID-0

Oh my!

You shouldn't have got that model. It is an old family. You should have gone with 250HJ. 251HJ or 252HJ.

AFAIK he has a nVIDIA chipset.With nVIDIA chipsets harddisk transfer rates are lower compared to other.No matter what you do they have lower transfer rates.One drawback in nVIDIA chipsets.

yah the prob may be with the chipset

this is wht i found
s.bridge : NVIDIA® nForce 650i SLI (C55) Chipset
n.bridge : NVIDIA® nForce 430i (MCP55) Chipset



On-Board IDE / SATA

• Two IDE controllers on the NVIDIA nForce 430i chipset provides IDE HDD/CD-ROM with PIO, Bus Master and Ultra DMA133/100/66 operation modes
- Can connect up to 4 IDE devices
• NV RAID supports 4 SATA II ports (SATA1-4). Transfer rate is up to 300MB/s
• NV RAID
- Supports up to 4 SATA
- RAID 0 or 1, 0+1, 5, JBOD is supported
- RAID function work w/ SATAII H/D

Don't compare with KZRO's screenshot.
Compare it with this.

KZRO n gayannr both have the same HDD ne? bt why there is a huge difference?

 

[Sasika@Elakiri]

damn i havent posted mine here, nwayz, the HD250HJ scores 105~108 MBps Maximum Read speed, 68~70 MBps Minimum read speed, Burst Rate is 215~150MBps (its 200s on the Jmicron Controller) this is on ICH9 southbridge, ofcource Depending on the SATA controller, but very slightly, Burstrate can go really bonkers but other rates stay very close what i achived here all the time, look at Anushas and Gayans screenies, ur Transfer rates look pretty weird indeed sasika, 40ish minimum is not that good, and ur burst rate is really bonkers mate...u should stick the HDD on another PC and check it maybe its defective. plus the Curve should be pretty smooth, but look at urs its spiking every few seconds, KZRO's is worse must be sumthing with the controller

Yes i will chk, i think the chipset matters most probably.
curve is not smooth bt is it really spikin ? i see flat ends. i thought this way the better, coz its stable right?

thanks

machan me gana hodada???

Maybe the HDD was in use when he ran the benchmark.

Also, the ICH9 seems to do a better job. It fluctuated even on mine. It does that for every drive on my mobo

There is no problem with your drive. That is the curve you get for F1s.

KWl

so is AHCI enabled by default for SATA HDDs within XP?

AHCI should be enabled from BIOS. BIOS defaults set it to IDE mode for all mobos as far as I know.
Win XP doesn't have a native AHCI driver. Drivers need to be installed at OS setup time, usually from a floppy disk. There could be alternative methods however.
Win Vista has native support for SATA HDDs, but better to install specific drivers after setup.
