Acronis DD-11-Home and TI 2014 both manage the SSD alignment perfectly when cloning from HDD.
To tell the truth, when it comes to shelling out more than $100 for an SSD of any size, I'd been more careful.
A friend called me yesterday with a heads-up about a 24-hour deal at the Egg for the MX100. Reviews are sparse, but all stellar. I saw the Anandtech review. I'm planning some upgrades to household workstations in general, so I ordered two.
Someone complained that they don't come with software for firmware update. I'm sure there are some downloads at the Crucial web-site. For the price, the complaint is nit-picky.
I had upgraded my sig-rig with an 840-Pro, to discover that I still wanted more SSD capacity. The option that comes to mind first: replace the 512GB drive with a TB EVO. But for less than half what I paid for the Pro, I can add this MX100 -- maybe configure it without a drive label as an "extension" to the Pro.
As for some . . minor shortcomings as noted in the Anandtech review -- who cares? "Fast enough" is more than fast enough . . . Given what I paid for the 840-Pro, I almost wish I'd held out for a few more months until the MX100 was released at this ~$220 price-tag. Live and learn!
