Vertex 4 only running at half the rated speed?

2 days ago I upgraded from an Intel X25-M G2 80GB to a Vertex 4 512GB. I expected some improvement, even more so considering I reinstalled win7 after a few years of continues use. However I'm still getting laggy programs on occasion in scenario's that I imagine would be gone with a good SSD. I can't tell if the bottleneck is somewhere else or if it really is the SSD.

I ran a few quick benchmarks to see if the drive was performing close-ish to the level seen in most reviews.

Here's a screenshot of a quick bench done just now for screenshot purposes:


And the Intel X25-M G2 80GB just for the hell of it, which is nearly full:


For comparison, here's Guru3D's benchmark of a Vertex 4 256GB with firmware 1.5:

As you can see the numbers for the vertex are all lower except the random 4K read/write ones, they're actually higher for some strange reason. These tests were done after installing windows and a whole bunch of other stuff on the SSD like games, photoshop, mpc-hc, etc etc. which has already filled 180GB on the drive so I expected some reduction in performance but not this much.

It's plugged into a SATA3 port on of my Asus P6T Deluxe V2 and AHCI is enabled in the BIOS. The drive came with firmware 1.5 but before installing windows I pressed the update button on OCZ's tool anyway just to be sure.

I don't know if these performance numbers are game changing even for a heavy desktop user but I am concerned that I haven't configured the drive properly. Anyone have any idea's?

That drive is definitely running in SATA 3Gbps mode.

Edit: You have an X58 motherboard. This chipset has no support for SATA 6Gbps. Thats why the speeds are about the same as the previous Intel drive.

lol yeah thought you may feel like that.

And the answer to what you're thinking now is no. PCI Express SATA 6Gbps cards are garbage, perform worse than Intels native SATA 3Gbps ports and have also been known to introduce stability problems as well.

The only way to get decent SATA 6Gbps performance is to buy a 6 series chipset or newer board.

Your getting half performance because your on a sata 2.0 mobo, just like me.
I get 260mbps and it can do 520Mbps read. The Vertex of yours might have needed a firmware upgrade. Check for that. If they offer you any software.

The device you have is sata 3.0 but your running on a motherboard that is SATA 2.0

Those numbers are correct for 2.0 sata. On your new computer youll get 500mbps and be happy with new system and double speed.. gl

Unless you're willing to shell out for an LSI card which is probably gonna cost more than the SSD itself. I think someone in this forum did but he is running 4x SSD's in RAID0.

Going from SATA2 to SATA6 wont exactly make the SSD blazing fast compared to the old. Besides benchmarks it will barely be noticeable.
