SSD upgrade: How it boosts Mac performance

Your older Mac that has a hard disk drive (HDD) for data storage probably runs a lot slower now than when it was new. If you need a faster Mac, you can upgrade it with a solid state drive (SSD), the new standard in data storage. Learn why SSDs are better than HDDs.
They’re more reliable
Most consumer SSDs use NAND flash memory, a type of nonvolatile storage technology that doesn’t require power to retain data.

How to avoid Spectre & Meltdown attacks

Hospitals and clinics have been storing confidential medical files and patient data in highly protected servers. But unless patches are being installed, Spectre and Meltdown attacks could undermine the security of healthcare providers.
Why is Spectre and Meltdown a big problem for healthcare providers?
Spectre and Meltdown are security flaws in computer chips that give hackers access to all data saved in the server, circumventing even encryption and multi-layered security systems.
