New vertex 3 going very slow

dandos23 · 16 May 2011 at 20:56

Hi guys

Hope someone can help me out
I got a new vertex 3 a little while ago for my new build that I am doing. As it will be a while till the new one is ready I thought that I would check the drive on my current rig.

I know that I wont be getting the max speed out of it as I don't have sata 3 but this seems a lot slower than I thought it would be.

I have set it to AHCI in the bios and it is a new install of windows.

Any idea what's going wrong?

~270 is the SATA II ceiling. What controller is it on?

according to his motherboard spec it only supports Sata2, so no 6GB/s

Dont worry about it, my SSD maxes out my SATA2 connection, when I get a new motherboard with SATAIII, I expect to get better scores.

Seems ok, my OCZ gets similar on SATA 2.

I think that's about what you would expect from SATA 3Gbps. After overheads 250-275 is the maximum realistically achievable.

Buy another drive for 500 or just forget benchmarks as it's a cracking drive

Check out ocztechnologyforum for more details (if you haven't already).

The top speed of it is ok and I know that on sata 2 it wont go any faster, but look at the first few lines. That bench took nearly 5 mins to do.

look at the line graphs, see how performance increase with queue depth.

I understand all that (just), but I can boot up quicker using my normal HDD that is 4 years old and has loads of stuff on it. This took about 3 mins just to boot up and even then I cant do anything for another 2 mins.

Here is a screen of the bit I mean.
I have no read speed and no write speed on some of them.

stulid · 16 May 2011 at 21:29

If that value on the left side is I/O's then its similar in the way speed increases with more operations, than the storage review benches above.

Check out theocztechnologyforum. Some pretty helpful and knowledgeable people on there as well as sticky posts about benchmarking these drives.

Why is this persons like this then and how long should it take to run this bench (my HDD can do it in about 30 seconds)?

Try a different SATA port?

Ch3m1c4L · 16 May 2011 at 22:23

that is a bit weird to have a few hundred bytes a second read or write, as stulid said try a different port and cable, check the latest amd drivers are installed etc, make sure ur not using a well old version of atto.

dandos23 · 16 May 2011 at 22:54

Right, I have tried every sata port with 5 different cables and they all do the same. Except that the the no read /write will move about a bit (always be below 8.0 though)

Thing is when I connect it to my sata 2 controller card it works fine (only up to 145 MB/sec though) so I am sure it is something to do with the controller.

have u got latest drivers for ur amd board?

As far as I know I do but I will try to update them.

Thing is, that drive wont be used on this system anyway. I just wanted to check that everything was working ok. When it was taking ages to do anything I started to think that there might be a problem with the drive but I proved that wrong when I used the sata controller card that I have.

Ch3m1c4L · 17 May 2011 at 18:24

id imagine its either a driver issue, random incompatibility, or something else accesing the drive at the same time, like if ur anti virus scans everything on access maybe it reads the data as its being written etc.

only other option would be if some weird setting is incorrect
