Getting poor write speed on SSD on cMP1,1

[Zeke D]

I'm under no illusions that I'll get the full 300MB/s that SATAII is rated at, but 150MB/s write speed seems too low. Am I managing my expectations appropriately, or is 150MB/s standard fare for the 1,1 with the SSD installed in a drive bay with the NewerTech Adaptadrive?

I'm getting here speeds with a Samsung EVO in my 5.1 cMP in a drive Bay.

Assuming the SSD has at least 20% empty space. I will do 2 things.

1) Check the spec of the SSD, find out the expected write speed

2) Check if TRIM is enabled, if not, enable it

Some of the cheaper 128gb SSDs only get about 180 mbps write speeds so I am not that surprised.

Just have a quick check of the V300 (120G) on Google. OP's write speed is normal for Incompressible data. It's the expected behaviour of the SandForce controller.

Avoid Sandforce SSDs folks. They're awful.

Thanks, all y'all. I contacted Kingston, and they're going to replace the drive. They market this drive as a 450MB/s drive, so there's no way they should be able to give me a drive doing 150MB/s and claim 450MB/s. I'll let you all know how I fare with the new drive.

Unfortunately, I think you'll find there is nothing wrong with that drive. The replacement will behave the same, mark my words.
