Again, the Mac only sees one drive, but it’s actually backing data up to both. RAID 1: This array mirrors both drives to each other.The app's instructions are well-written and can quickly guide you through it. You don't need any special enclosures for this you can build it in your Mac's Disk Utility app by running the RAID function if you have two spare external drives lying around. Don’t think about RAID 0 as two drives think about it as one ultra-fast and ultra-risky storage solution. If one hard drive dies in the RAID, that means that the other one is useless. This allows your hard drives to be twice as fast, but it also means that they’re twice as likely to fail. A bit of information about one file will be on one hard drive and the rest of it might be on the other.
Instead of using the disks independently, the computer only sees it as one and stripes the data across both. RAID 0: This is the most common setup in the market, where data is stored across two disks.Three different types of RAID, that best summarize these factors, are: RAID 0, RAID 1, and RAID 10. RAID allows two things: it allows speed, or efficiency (which is called striping), and it allows mirroring, which is redundancy. You need to know what you're building before you decide on what you buy. It’s difficult to explain what RAID is without understanding the different sorts of RAID, so I’ll simplify my explanation by saying that RAID allows you to configure multiple hard drives together as if they were one drive, letting your virtually stack them. In fact, RAID can be described perfectly by its name: it’s redundant. RAID, which stands for Redundant Array of Inexpensive Disks, isn’t really a backup solution.
2017 BEST EXTERNAL HARD DRIVES FOR MAC HOW TO
In this tutorial, I’ll show you how to select the right storage and backup regime for your Mac. I run a small business, and for me, having a large home storage and backup system for all my clients’ data is of critical importance. There’s a lot of good reasons to explore different ways of backing up information and preparing yourself for the worst, especially as more of our data ends up on our computers than ever before.
