Very slow write speeds with new 60gb Phoenix Pro

[six.four]

I have a new Phoenix Pro drive I just took out of the box and mirrored my current Windows 7 OS drive (a Gskill falcon 64gb SSD).

I'm running AHCI in bios, have the latest Intel Rapid Storage drivers, and have done all the Windows 7 tweaks (enable write cache, disable hibernation, disable system restore, etc). I also checked that Trim was activated.

I left my computer idle for 8 hours to see if the garbage collection would help - but it didn't.

Forgot to mention, the drive is running FW 2.1

Here are my benches after the 8 hours:





Any suggestions as to why I'm getting such terrible write speeds?

Thanks

Hi six.four

how did you mirrored from Falcon?
did you use CD/DVD or software?

thanks

Hi - I used acronis true image home.

I was thinking about mirroring my drives too. I get those speeds and better somtimes just running the OS off a (non mirrored) SSD. I just think the OS steals the drives bandwidth or the SATA controllers bandwidth even. Try running it as a slave and then bench it i haven't even tried that yet.

But see, I have searched alot in these forums and I did not see anyone mention testing as a slave.

P.S. Whats in your hardware specifications?

I wasn't even aware SATA had a "master/slave" configuration (unlike IDE drives).

Do you mean just running the SSD as a non-bootable drive instead of a bootable OS drive?

My Specs:
i7 920
Asus p6t deluxe
3gb DDR3
60gb Phoenix Pro
2x 1tb HD
ATI 4850 + 2x ATI 4550
Windows 7 Pro 32-bit

Hi six.four

did you use red SATA port.
your motherboard has "red" and "orange" port.
please use native port(red color) and set AHCI mode.

[six.four]

tested it on all ports - red and orange. Currently on red. Though I did not notice any difference in speed between the two ports. I even tried different SATA cables. Same benches.

Hi six.four

did you set to AHCI mode?

what SATA driver did you use?

[six.four]

Yes. The BIOS is set to ACHI.

Using the Intel ICH10R SATA AHCI Driver - version 9.6.0.1014

Must be my old-school mind kicking in again.

Yes

Hi six.four


I will figure it out as soon as possible.

Actually install OS will affect its performance but it should not be so serious.
If SSD can't be bootable OS drive, I think we don't have to waste money.
We know use some kind of software(like ghost....) to mirrored OS make performance drop.
Because original OS is not clean.

maybe you can try to reinstall new OS.

I'd prefer not to have to reinstall the OS as it would require a considerable amount of time and work on a workstation that I need for work - so I would only like to do this if there are no other options for solutions.

I would think that garbage collection on Windows 7 would clean up any residual left behind from the mirroring process.

Its still so unbelievably disconcerting that you loose roughly 80Mb/s with the phoenix ssds.
Ive reinstalled and step by step did everything right but those scores on the main webpage are unreal.

However if you run the computer in your head you think...

1. maybe they tested it as a single drive
2. maybe they tested it as secondary
3. maybe they tested it with a high-end raid controller

Why is the drive at a loss of around 70MB/s 80MB/s

1. maybe all the drives where tested vigorously passed then shipped
2. maybe the other hard drives in your system leech bandwidth from your on-board SATA 2.0 controller
3. maybe your operating system leeches bandwidth regardless of mods/tweeks
4. maybe problem 1. , 2. and 3. combined

My drive test today

I agree, it is pretty disconcerting. Perhaps if I have some time this weekend or next, I will attempt to move my files back to my old falcon SSD and run the bench on a blank phoenix pro to see if that helps.

I will report back with my findings.
