Silicon Power V60 POOR performance...

post #1 of 8
Thread Starter 
Hello there,

I've just installed a fresh win7Pro on a P8H77-V Mobo, 16GB, i5 3.2 Quad system.
As my Samsung 840 started to loose blocks, I have to send it back and I bought a Silicon Power V60 (the only SSD available at the time).
Though BIOS is AHCI, i have real bad performance.

Anyone has a suggestion?
What can be wrong?
Box says 500/550 MB..




edit:

Updated Intel Driver:



Same (or worst)

Here's a review of your SP V60, which I think is the same SSD, a Silicon Power Velox V60, is that right? This review will give you a better idea why it might not perform as good as you hoped for:

http://www.xbitlabs.com/articles/storage/display/siliconpower-velox-v60-transcend-ssd720.html

The specs for your SSD were taken from the ATTO benchmark program, not AS SSD. Search on ATTO (free) and give that a try.

Your AS SSD results seem too low for a SP Velox V60, are you sure you are using one of the Intel SATA III ports on your board? It only has two SATA III ports, the other four are SATA II. Your speeds are not even at a SATA II level.

The V60 does use synchronous toggle NAND made by SanDisk, but the review does indicate the design may not be using the best way of connecting those chips to its SandForce controller.

Thank you for your answer. I am actually connecting it to the primary (white/gray) SATAIII port... I will check ATTO benchmark and see what happens.

Edit:

It happens this:

Which means that 16 up it seems to reach expected results.
But I am confused: is this benchmark good? Why is this so different from the other one?

Just don't understand..

That looks normal? Its not all going to read 500+ all the way down.

The SandForce controller in your SSD compresses data to speed up I/O.

Your SSD with Async NAND with SandFroce controller = non advertised speeds with the fully compressed data that AS SSD tests with.

With ATTO it tests with fully uncompressed data, therefore the SandForce controller can compress the test data on the fly and you will see improved speeds.

Well. At the everyday use it seems running well. I use it for the OS and Lightroom and the related catalog, so to speed up everything.
Anyway I have a Samsung 840Pro that should be replaced soon, maybe I will swap the disks.

Another question for you all. When I will have my Samsung returned, is there a way to clone OS and sw from one disk to the another flawlessly? I mean: with SSD disks, is it better to re-install everything or I can use some utility to clone?

Thanks in advance,
Paolo

cloning works fine. I like aconis true image.

also this tool too: http://www.xxclone.com/

You're just one of many people, that got fooled by sandforce speed figures. As it was stated above, it reaches these kinds of speeds by writing or reading almost nothing, as empty data compresses very well, as such does not require that much actual nand activiy.

Your speeds are just fine.
