Power Consumption

Samsung sampled the 512GB version of the SSD 830 so it's unclear how much the sheer number of NAND die impacts power consumption here. At 1.22W while idle the 830 seems to draw 28% more power than the Intel SSD 510. Under load that gap drops to only 14% during sequential writes but skyrockets to 70% under random writes. Again part of this is likely due to the higher capacity. Until we get lower capacity drives it's impossible to tell how much the power consumption story will change.

    problem is everyone else has had more problems

    Speaking of reliability, aren't those the old results on the M4?

    Thanks for the heads up, updated :)

    Take care,

    ...anyone noticed? Though this one would be nice for like a x220 that only takes 7mm drives but with power consumption more than double of a crucial m4 especially at idle...basically kills it for mobile use.

    Yeah, it almost approaches 5400 rpm HDD idle levels..

    Update: Storagereview.com measured idle power consumption of a 256 GB drive to be just 0.31 W, which is much better and just normal (or even good).

    Once again, for mobile the issue is not IDLE power use, it is PEAK power. If your system is not specced to handle that peak power, it will crash whenever there is a sequence of back-to-back writes.

    I think you're misinterpreting his comment. IDLE power matters for laptop users from a battery standpoint. Yes it's going to be a small % difference due to the large(r) draw of the screen, cpu, gpu, etc. but it does add up. We do understand your comment about crashes but I think the OP's comment is in reference to something that is going to ALWAYS be using more power than a competitor as being bad.

    I do not know what burst power consumption is on mechanical HDD's but would imagine they are at or above what even the most power-hungry SSD consumes. This would be an interesting mini-article Anand!

    Burst on SSDs tend to use more power than many HDDs.

    So what 7mm SSD would you recommend?
