Power Consumption

Drive Power Consumption—Idle

Drive Power Consumption—Sequential Write

Drive Power Consumption—Random Write

Power consumption is pretty standard SandForce. Idle power consumption has always been fairly high but load power consumption is about average, unless you're writing incompressible data which increases power consumption significantly.

    I see, but that doesn't really answer my question :P.

    Is there still a performance hit and do you just choose to test under normal rather than optimal conditions or is this a thing of the past?

    I tested this quickly a while back but there was no significant difference in performance (small variation always occurs anyway):

    Thanks for the replies :).

    You say "AFAIK it affected performance with some older SandForce SSDs but when I started testing SSD and asked Anand for all the settings, he just told me to leave it on since it doesn't matter anymore".

    But it's a clear difference on my old postville. Granted, the SSD is my boot disc during those tests, but isn't that their most likely use anyway? TBH I'd be interested to know why enabling those powersaving features apparently impact performance only when used as boot disc. When I say 'impact", I mean based on multiple runs, of course.

    Lastly, it seems that C-states are the most impactful setting and that one isn't mentioned in the reviews. I suppose you've left those on as well?

    that wasnt testing.

    Don/t buy MLC rubbish. SLC is really worth it.

    Nice going SandForce.

    1) BSOD problem
    2) AES-256 hardware doesn't work (seriously??? hardware doesn't work???)
    3) TRIM has not been working properly (what, you failed to GC blocks properly?)

    As a lot of people mention, these SSD makers want to use early adopters and PC building enthusiasts as guinea pigs.
