Trans International has introduced the Pro Sled, a $29 kit to make it easier to insert and remove hard disks from inside a Mac Pro.
The Pro Sled helps you swap out internal SATA drives (after the Mac Pro has been powered down). The drives plug in to the Mac Pro’s main logic board; no power or data cables are required.
Using Pro Sleds, you can assign a drive for different clients, projects, or for backup, store them when they’re not in use and so on. Trans offers discounts for multiple Pro Sled purchases.
