Join Mike Meyers for an in-depth discussion in this video Implementing RAID, part of CompTIA A+ Exam Prep (220-901) Part 2: Core Hardware.
- When it comes to using RAID on your system,…you've got a choice.…You can either do software RAID or hardware RAID.…When you're doing software RAID,…you're letting Windows do all the work for you,…and there's nothing with it,…but it takes a lot of overhead onto Windows…to do that RAID for you.…If you want really great RAID,…and you want all the fun features,…the thing to use is hardware RAID.…(upbeat festive music)…Pretty much any typical, higher-end desktop motherboard…has hardware RAID built into it.…
You just pick a certain number…of your regular SATA connectors…and you reconfigure the system to do RAID.…The downside to this is that the vast majority…of motherboards are either all RAID,…or all just what we call JBOD,…just a bunch of disks.…In other words,…let's say you plug a system into here…and you format that hard drive…and you make it perfect, nice Windows set up,…you're ready to go, and you decide,…oh, I'd like to do RAID 5.…Well, you really can't.…What'll end up happening is…you're gonna have to take that extra drive,…
The CompTIA A+ 220-901 exam is comprised of six key parts. The second, core hardware, is covered by this course. Instructor Mike Meyers explains the essential components and functions of motherboards, power supplies, and hard drives. He also shows you how to work with chipsets, troubleshoot electrical issues, implement RAID, and how to determine which hard drive technology to use depending on the circumstance.
Note: The six courses designed for the CompTIA A+ (220-901) exam preparation include core processing, core hardware, peripherals and building a PC, displays and printers, networking, and laptops and mobile devices.
- Working with motherboards, chipsets, and expansions
- Choosing a power supply
- Evaluating hard drive technologies
- Implementing RAID
- Troubleshooting issues
