OCZ Arc 100 Slowness

[asm0deus]

I bought an OCZ ARC 100 during a Newegg deal a couple weeks back (for $109). I'm trying to figure out why my speeds are slow. I also bought and installed a SATA III controller to go with it (SYBA Marvell) into a PCIe x1 slot. I'm guessing that I'm hitting the limit of the PCIe bus when I'm scoring so low on benchmarks in the 200MB tops range.

I have an older mobo: Gigabyte GA-EX58-UD3R v1.0 and I see that my original Windows 8.1 install was using IDE (instead of AHCI) I cloned that install and then set to AHCI in BIOS. I'm guessing I can increase speeds by reinstalling fresh as AHCI and using onboard SATA II versus the new SATA III controller on PCIe x1 2.0. My CPU is i7 and I have 12GB DDR3 so the rest of the system is decent enough until my next upgrade.

But I was curious if anyone could shed some light on my most limiting factors here. I'll probably try switching over to on board SATA II just to run a comparison. Then try re-installing windows over the weekend. Here's my drive config, it's looks like AHCI is active if it's showing on the list but maybe its not entirely setup since I'm not using the AHCI driver in the benchmark.

I'm thinking you're wrong about having it in a PCIe 2.0 slot. If you don't have 2 GPUs, try moving the controller card to the other 16x slot, and see if speeds don't improve by quite a bit.

OCZ

Problem found. You should return it. The MSRP is only $120. I dont know why you thought $109 was a deal. For the trouble of dealing with OCZ products, you shouldnt pay more than $60 for that drive.

$60 for a 240GB SSD? New? I'd like some of what you're smoking.

Don't mind sm625... there is still a lot of OCZ hate out there.

OP, just listen to what Cerb is saying, I think he is on the right track...

Cerb was right. I moved the SATA3 controller to my x16 slot (after moving the video card down to the bottom one) and I'm getting much better speeds. Thanks for your help guys. I'm pretty happy with 380MB/s for now until next upgrade.

WUT!?! It's not because it says 'OCZ' on the label?

Good deal... glad it was an easy fix!

For years I would agree with you, but remember now that OCZ are owned by Toshiba and the ARC 100 is a current product. OCZ did release a lot of junk, but I would be more willing to buy one of their drives now they are owned by Toshiba.
