When you install Lion or Mountain Lion, you need a network connection. Because some networks can be unreliable, you may want to set up a thumb drive as a restore disk. When I reinstalled Lion on my old MBP, the estimated install time was 78 hours because my network was having problems.
To avoid problems like that, you’ll want to get a flash drive and create your own recovery disk.
Here are some USB flash drives that may interest you:
My choice: Kingston SE9 16 GB / $10
A simple, elegant flash drive that goes well with the MacBook Pro & MacBook Air.
- 16 GB / $13 Super Talent Pico-C
- 16 GB / $10 SanDisk Cruzer Blade
- 16 GB / $12 SanDisk Cruzer Fit (32 GB / $23)
- 16 GB / $23 Adata S805 Sport has a carabiner-like clip
- 32 GB / $23 SanDisk Cruzer Fit
Speedy: USB 3
The new MacBook Pro with Retina display has two USB 3.0 ports. The USB 3.0 drives are clunkier, but have faster transfer speeds.
