Pros: Easy upgrade to get MacBook to 6GB beyond tech spec of 4GB. All 6GB get used with a 1x2GB and 1x4GB. Delivery to Prairies within a week.

Cons: Price is up there for memory, but a relatively inexpensive computer upgrade overall.

Pros: A good size from a reliable manufacturer for a very affordable back up solution. Use in a Mac Pro 5,1 as a secondary Time Machine backup to a home network of 3 laptops on WiFi. Am thinking of using another like this to replace the original 2TB disk in a separate Time Capsule WiFi unit.

Overall Review: Install was simple, worked immediately to complete 3 full backups of about 15 hours each when I staged them. Works ideally with Time Machine to pick up subsequent mini backups. No troubles. On delivery, drive was very secure within a tight bubble pack, box was exact size to reduce packaging waste.
