Disks Today
So what’s springing up to take their places? Let us count the disks.
Hard Drives
Thanks to the Mac’s Thunderbolt, FireWire, and USB jacks, it’s easier than ever to attach an external hard drive for extra storage.
CDs, DVDs
Current Mac models don’t have built-in DVD drives, but you can buy an external one. Which is handy if you have a many-hour flight ahead of you and want to watch some movies you picked up at the library.
CD-ROM stands for “compact disc, read-only memory”—in other words, you can’t freely add and delete files from one, as you can from a hard drive. But most Macs can also record onto blank CDs, of course, and blank DVDs, too, thanks to a built-in CD/DVD burner.
The standard Mac can also play DVD movies that you’ve rented or bought, but you may also occasionally use it for data DVDs—that is, DVDs that contain Mac files or software installers.
Flash Drives
The most recent invention is among the most convenient: keychain-sized flash drives or thumb drives, which plug directly into your USB jack and serve as low-capacity hard drives with no moving parts. Inside, they contain nothing but RAM—pure memory.
Flash drives are fantastic, usually inexpensive gadgets that hold as much as 512 gigabytes or even 1 terabyte. They work on any Mac or Windows PC and don’t require any drivers or special software installation. Ask for one for your birthday.
