I do not think Aspera would be able to transfer the initial snapshot "really fast". This technology seems to be only only sending incremental changes, based on real-time (or near) monitoring for local changes. When adding any off-site data storage service (does not have to be cloud - replication to newly added second datacentre is possible example) then the initial snapshot could take a long time, and sending it in a "hard format" instead makes sense.
IBM packs 120TB into a carry-on bag, for snow-balling cloud uploads
IBM has decided to join AWS and Google in the appliances-to-haul-data-into-the-cloud market, by launching an appliance called “IBM Cloud Mass Data Migration”. Readers familiar with AWS' Snowball or the Google Transfer Appliance already know what this box is all about: there's 120TB of disk inside, a couple of Ethernet ports, …

When I last used Aspera (some time ago admittedly) it speeded up the file transfers by things like using UDP and multiple streams, kind of like bittorrent for business. It works: with fast enough readers/writers at either end, it could saturate the link inbetween (where perhaps an FTP or equiv would see a very spiky use of the link). But it couldn't go faster than the underlying link capacity (e.g. there was no compression-type technology when I used it last).
A quick fag packet calc suggests 1TB could be transferred in 15 mins over a 10Gb link, if you could get 95% usage out of it; and 25TB in about 6 hours. Pretty reasonable! And faster than the 120TB bag of disk (especially considering you have to also transfer 120TB into and out of the bag, which would probably be the same sort of time as above I suppose). So if you have (or can afford!) a 10Gb link and use it with Aspera, that would probably be the fastest way.

Most cloudy vendors now offer this
Amazon, Google, Oracle, IBM
But the problem is not creating a flight case with some disks and ethernet ports...The trouble starts when you try and get this into a DC and connected to a rack (probably managed by a 3rd party who is losing the business and still has an SLA to meet).
In almost EVERY case I have seen it is quicker to just take the hit and move it over the network

Yes, Aspera at the high end of its performance range is eye watering expensive to the point where it is just not viable. Although it takes 60 hours to tansfer over the net how long does it take to load up the CMDM transport it and dump into their Cloud? 60 hours could be relatively short ( if you can afford it or use one of the alternative WAN Acceleration products)
