Hi all,


Please could someone tell me if I have incorrectly set something as I am not getting the high sequential read speeds that other users of this drive are. The other figures seem about right...

Heres my AS SSD screenshot:

My machine is as follows:

Asus P6X58D-E
i7 950 @ 4Ghz
Corsair Hydro H80 Liquid Cooling
Corsair Dominator 6GB (3x2GB) DDR3 PC3-12800C8 1600MHz
HIS ATI Radeon HD 6950 IceQ X Turbo 2048MB GDDR5
Corsair TX 850W V2 PSU
etc etc.


I have the drive connected into the Marvell 6gb/s controller which gives me these readings. If I connect it to the Intel 3gb/s then the read drops to 270 and the other figures are about the same.

It was a fresh windows 7 install. Just plonked the dvd in and let it do everything. The only thing I have disabled is indexing and defragment. I did do the update to 0009 after the windows install if that makes a difference?


Thanks in advance!

lol, Thanks :)


Yes I have it in AHCI mode. Not sure about TRIM though....


Would it just be down to the marvell controller or is there something I can do to improve it?

If its the marvell controller, whats my options?

I think it's just down to the Marvell controller.

There a few threads of people complaining how crap it is.

As the speeds of the SSD are Sequential Read (up to) 415MB/sec and Sequential Write (up to) 175MB/sec you're not exactly missing out on a lot.

There's not a lot of point in buying an add in controller as they're Marvell based as far as I'm aware.

Asus make this but I'm not sure you'd see any better results. Your motherboard isn't listed as compatible but I don't see why it wouldn't be. Some even use the card with none Asus boards.

To get a chipset with native SATA 3 ports you'd have to upgrade the motherboard and processor at a minimum.

You're getting around 91% of the theoretical maximum read speed so I'd be happy with that if I were you rather than spending money trying to get that last few percent.

Hey Surveyor,


Thanks for the response. You have put my mind at ease :)

Don't really wanna start forking out loads more money to get just a little extra mb/s.


At least I havnt done something wrong to cause the lower speeds :D


Cheers

Actually with the 0009 firmware which he has flashed the max sequential read speed is around 530MB/s so he's missing out on a ton of speed.
 
There is no other choice than getting a motherboard with native SATA 3, I was just plainly stating that he's missing a fair amount more speed than you were stating. It's up to the OP if he thinks it's worth spending a ton of money for that extra speed, I personally wouldn't get a new motherboard/processor just for extra SSD speed.
 
you'd have to be doing something where you measured it in the Millisecs to notice the improvement you 'MIGHT' gain by getting a new mobo....not worth i say.
