1 - 13 of 13   When should I use the different levels of RAID? Here's a synopsis of the different RAID levels as well as when to use each one. RAID is 20 years old. Is it as applicable today as it once was? RAID technology is 20 years old. Is RAID still as applicable today as it once was? With a shift toward solid-state disk and semiconductor memory-based storage, does that diminish the need for RAID to boost performance? No, I'd say that RAID is still necessary. RAID and solid state complement each other. There's a notion that RAID is just for disk drives, and that's not the case... With the advancements in RAID and storage systems, how come RAID still isn't a replacement for backup? This is something that's been talked about for quite a while. RAID is really about availability. The idea is, with RAID, you're protecting against device failure, drive failure, component failure or a failure to be able... Can you explain what dual parity, distributed parity and network RAID are, and why are they getting more and more attention? There's some confusion and different marketing terms out there. RAID 6 is a common one. RAID 6 is an extension of RAID 5... How can RAID be used to address green IT issues, and power and cooling challenges in the data center? RAID is a tool. It's one of several tools that you should have in your 'green toolbox' or your power and cooling toolbox, if you will. RAID comes into play when dealing with data that isn't frequently accessed... What are the performance issues with RAID 6 or dual-parity schemes? With RAID 6, you can theoretically get double the data protection without doubling the number of drives. But you'll need to work around the performance penalty. Is RAID only relevant for the enterprise, or should SMBs and SOHOs be concerned with RAID? RAID is relevant for the enterprise, the SMBs, the SOHOs, and RAID is even appearing in... Where is the best place and best technique for implementing RAID? Of course it's the old adage: Wherever it makes sense. And where does it make the most sense? Well, its whatever... It seems like 'hybrid' drives will be here long before true 'solid-state' drives. How do hybrid drives play into RAID schemes and tactics? RAID can be used for availability and for redundancy, but it can also be used for performance... What's happening with disk rebuild times? How do 'preemptive rebuilds' work, and what other techniques are appearing, if any, to accelerate rebuild times? On one front, rebuild times are actually getting better... What does the future have in store for RAID? RAID recently was diagnosed as a dead technology. Some people in the industry call it a zombie technology... What are some general things to watch out for and be aware of regarding RAID? You want to look at the RAID, but also the storage system it's being implemented on. For example...   1 - 13 of 13
