Power Consumption

As I mentioned on page one, the Ultra II does not support DevSleep, but it does support slumber power. SanDisk decided against DevSleep support based on the fact that there are only a handful of systems that support DevSleep and most of them are already equipped with M.2 SSDs. In other words, DevSleep is not a feature that adds value to the aftermarket buyer because it will not be supported by the device anyway.

Overall the Ultra II has great power characteristics. The slumber power is low (although not the lowest) and under load the Ultra II is very efficient and stays at about 2W.

    Interesting stuff, good to see that competition is picking up in this market. I think it will be a significant threshold moment when we see the 240gb SSDs drop below $100. Reply

    I just saw an OCZ Vertex 460 240GB drive go for $104 the other day on newegg, and of course there sold out. Thats Nucking Futs, since i bought a 120GB 840 pro last year for $140 and the speed looks to be about the same, possibly faster in some ways on the OCZ Reply

    But then, it is OCZ, and many people who know their tech history, wouldn't take an OCZ SSD for free (regardless of whether they are right or wrong in doing so). Reply

    I agree, really interesting to see and I'm looking forward to see what the future holds for SSDs. /Simon from http://www.consumertop.com/best-computer-storage-g... Reply

    I bought my first SSD back in 08. 16GB for 80$ Second SSD was 32GB for 100$. Third SSD was 64GB for 100$. Just bought a 256GB 840 Pro for 160$. We have come a long way. Reply

    Having an SLC cache is clever. I also like the low power consumption, reasonable performance, and especially the low price. I've had bad luck with the reliability of Samsung products, so it's great that they are getting some competition. Reply

    I've had nothing but stellar performance from Samsung SSDs. I have dozens of them out in the field, and not one single failure. Sandisk is OK as well... OCZ might end up OK since Toshiba owns them now. Reply

    I feel like with every new ssd review I read, I grow to appreciate the fantastic value that the MX100 represents even more. Reply

    Totally agree. We just outfitted our development PCs at work with MX100 256 GB drives and they are utterly fantastic for price/performance. I cannot at all get over how big an impact an SSD at work makes. FAR more than at home I can say. At least for average home use.

    We run multiple Visual Studio sessions and Oracle SQL Developer along with browsers and other misc apps so the impact has been just terrific.

    I know this article is old, but I was researching SSD's and as I trust Anandtech over any other tech site, I came here for the truth. The sad reality is, the MX100 has been overly praised, and is now priced (on Amazon) $72 more than the Sandisk Ultra II at same/similar (512 vs 480) capacity. The MX100 isn't Ultra 2 good......
