Wi-Fi is about 1/10th the speed of SATA, so no.

I think Wi-Fi will speed up faster than both SATA and disk drives, and SATA already is faster than portable hard disks. For example, http://en.wikipedia.org/wiki/IEEE_802.11ad aims at 7Gb/s. http://www.tomshardware.com/charts/2012-mobile-hdd-charts/-0... gives max read speed for mobile disks at less than 1.5Gb/s. Form that viewpoint, I can see a laptop disk drive that only needs a power connection. Battery-operated,…

I don't know the latency of SATA off the top of my head, but I would assume it would be less then that of Wi-Fi. With the way the OS currently controls hard drives, this proposal probably just won't work. Since this pretty much rules out an OS drive over Wi-Fi (lots of random reads), we could instead think of a NAS setup for mass storage. So we have a small NAS with Wi-Fi, with samba or NFS protocols, and use it as a storage drive.

Personally though, I don't mind having an internal SSD in my laptop (although it is a bit small, really should get a bigger one). I also don't mind cables for external storage drives. As for Wi-Fi, I usually have a hard time hitting the maximum bandwidth of my AP (where maximum bandwidth is slightly less then half the connection speed). Wi-Fi is also prone to interference. One interesting thing about the 802.11 ac spec is that it now supports channel bonding on upto eight channels, which severely limits the 5GHz band, which was supposed to take away all the congestion we have on 2.4GHz.

I hadn't heard of it yet when I wrote my earlier reply, but intel demoed a WiFi solution a few days earlier: http://www.computerworld.com/s/article/9231264/Intel_demos_7...

http://techreport.com/news/23303/marvell-wilocity-partner-up... writes about it:

"We're told latency will be in the order of "microseconds, not milliseconds"

So, latency will not be much of a problem with this solution.

I do have the impression that this is called Wi-Fi only on commercial grounds, not on technical ones.
