Low SSD Speeds

post #1 of 11
Thread Starter 
Never mind?

See ATTO bench
-----------------------------------------------------------------------------------------------
Hey folks, i've set up my SSD through AHCI and the latest firmware came installed, but unfortunately I am seeing very low speed compared to the advertised 550mb/s in Corsairs site.

I Have a Corsair FORCE 3 6GB/s 90GB SSD on a 6gb/s SATA III AMD SB850 Controller using the latest AHCI drivers.

I followed these instructions when installing Windows 7.
Quote:
Configure a drive as a boot drive using BIOS and MBR
Booting, partitioning and alignment of MBR for Windows and BIOS:
Boot from the Windows 7 installation DVD
When you see the "Install now" button (this prompt), click "Repair your computer"
You'll see a little window named "System Recovery Options" appear that searches for Windows installations.
When it finishes, you will see a dialog box. Select "Use recovery tools that can help fix problems starting Windows. Select an operating system to repair.", and then click Next.
Click "Command Prompt"
Type diskpart and press Enter to load DiskPart
Type list disk and press Enter
Type select disk 0 (or whichever number your SSD gets) and press Enter
If you want to be sure you have the right one selected, then type list partition and press Enter
Once you know you have the right drive selected, type clean and press Enter.
Type create partition primary align=4096 and press Enter (1024 Is default)
Type format quick fs=ntfs and press Enter
It will appear like it's going to take forever, but then it suddenly finishes about 5-10 seconds after it starts.
Type active and press Enter
Type list partition and press Enter to see your creation.
Type exit and press Enter
Type exit and press Enter
Click Restart
Boot from the DVD again and perform a normal installation using the "Custom (advanced)" type of installation. You do not have to manually format it.

I can't solidly answer anything but number 3 - don't worry about the number of writes. It'll last you MUCH longer than you'll actually be using the drive. Games, frequent writes, everything. Unless it's a specific problem with the SSD and it's broken - don't worry about that.

I was just wondering if you guys could help me out with a few basic questions I have. Please be aware that I am completely new to the SSD side of things and no ABSOLUTELY nothing about their workings and/or setup. I want to apologize ahead of time for bothering you guys with these [most likely] dumb questions.

1) Windows 7 Pre-installation checklist. Is there one to follow? I have heard the whole, "switch to AHCI" mess, would that be before or after the W7 install? What should I do before/right after boot?

2) During the installation, are there any drivers that are going to be required based on my AMD Chipset kinda with like RAID?

2) How would I go about keeping my current 1TB HDD RAID0 setup while using a SSD to boot W7?

3) Is it safe to have games, such as BF3, installed in the OS Solid State while being able to keep a decent performance over time?

4)What are the most important optimizations to do right away? I hear paging file to 4096MB and disabling certain features but I am not sure what would pertain to me.

I really appreciate you folks taking your time to read and possibly answer my questions, I'm sure you must get a million of these thread/day. i'll continue to read and hopefully i'll be able to pick up on all the stuff as time progresses over the next day or so.
1. Switch to ACHI before you install Win7 on your SSD. You may also want to unplug any other hard drives that are in your system before you install Win7 onto your SSD. The reason for this is that sometimes Win7 can create a "System Reserved" partition on a drive other than the one you're installing Win7 onto. The easiest way to handle this is to just unplug the SATA or power cable from any other drive while you're installing Win7.

2. No drivers will be required.

3. You don't have to worry about writes. Your SSD will be fine.

4. Whats important to figure out before you blindly follow any SSD Optimization guides is what is the basis for any of the changes suggested. A lot of guides will have you do a ton of different things and do not specify if the tweak will increase performance or simply save you storage space on the drive. If you have a 90GB SSD, I don't think you really have to worry about storage space. I would personally leave everything alone and let Win7 handle it. It is very smart about handling SSD drives (will automatically turn off defrag on it, etc) and IMO many of the tweaks on guides these days are horribly outdated. People aren't buying 16GB or 30GB SSD drives anymore and they don't have to get all crazy trying to save space on them.

Hope this helps. Congrats on getting an SSD!

The ATTO is the one you should look at since you have a sandforce SSD, I realised lately that most people don't know that they don't bench welll on AS SSD. Your system is running fine, no need to worry.

Awesome! I was hoping for some level of confirmation!

Thanks for the response and the SSD guide!
