Network drives on wifi

Back in 2010, when we were considering getting some Macs in school, one option we considered was getting a set of MacBooks for use by kids. As we already had some PC laptops which connected to the server via wifi, I thought we could do the same with some Macs. However, our reseller strongly advised putting in wired network connections if you are binding a Mac to an Active Directory as performance would be poor on wifi. I didn’t think much further about this as we ended up getting lots of iMacs instead, which all ran off wired Ethernet connections.

However, I recently tried adding a MacBook Pro to our domain, running it just on wifi, and this cautionary advice all came flooding back. Because we’re a big school, we make a lot of use of shared drives for saving work on. Working on a document off of a network drive requires a constant connection, which can become a little tiresome on wifi (particularly if the access point has a couple dozen iPads on it as well!). Having had enough of the spinning beach ball of death, I found a long network cable and plugged myself in.

Running documents off a server does feel a bit like living in the dark ages though. Admittedly, it is handy to be able to log onto any computer in the school and have all your document just there, but you do pay for it with a performance hit. Storage read and write is the last great bottle neck, which is why Apple is aggressively moving towards flash storage (Flash? We love flash!) wherever it can. The iCloud document model also makes a lot of sense: your documents live on your iPad/Mac/iPhone, but any changes are pushed to your other devices so that the same document is ready and waiting when you get there. That way you get the speed (and non-reliance on a permanent network connection) of a local document with the convenience of network storage.
