Is the AMD Sata controller any good?

[liamcrane]

Afternoon all, happy new year to everyone

I have finally bit the bullet and picked up myself a Crucial M4 64gb for £78. Im just curious to know if anyone has one of these running on an AMD sata controller, unfortunatly i will only be running it at 3gbps as my board is currently only AMD2+ with Sata II ports. Im looking to upgrade to an I5 Sandy setup fairly soon once i can afford to due to the expensive outlay with having to buy pretty much everything coming from an AMD DDR2 setup.

Anyway im hoping this might give me a nice performance boost for now until i do my full upgrade so just looking for some advice from anyone using one of these with an AMD chipset. Mine is the 785G chipset

Thanks a mill

Can't quite remember on older chipsets but, yes is the answer, its very good. I've noticed a grand total of zero improvement in benchmarks going from a SB850 to a Sandybridge mobo. In fact I think but can't be sure that several reviews often give sequential performance to sandybridge boards but AMD sometimes have better random read/write performance.

Either way, sata 3 isn't what makes the crucial drive fast, or ANY ssd, its the random read/write and the access time, both of which won't be effected by sata 2 or 3.

Keep in mind though that a 64gb Crucial won't benchmark anywhere near a 128gb, which itself won't benchmark anywhere near a 256gb drive, almost entirely the writes rather than the reads.

Anyway, can't be sure the 785g isn't almost bang on as good as the sb850, but I've used ssd's across AMD mobo's for a couple years at least now and sata 2 and have never seen randomly lower performance from a drive than Intel drives. In fact in terms of sata 2-3 performance and reliability, Intel has had a lot more problems. the first Sandy chipsets got recalled, and most of the more recent Sandforce based drives problems have been down to Intel's sata 3 implementation/drivers/bug work arounds from what I can tell.

I've got a 128GB M4 on a 790FX but the southbridge should be the same as mine. (SB750 with sata 2) I've only done the ATTO benchmark comparing the AMD 11.12 ahci drivers to the msahci drivers. My PC is freshly installed with win7 64 and takes 14 seconds to get to the desktop. (there is another 14s waiting for the post making it 28s from pressing the switch)
