RAID takes the first place for data storing technology when you need high performance and reliability. It seems like having all facilities in a box such as large storage, fault-tolerance, parity check ...

Ever since its invention in the late 1980s, Raid (redundant array of inexpensive disks) has been a mainstay of data protection on shared storage arrays and in enterprise servers. But, as the capacity ...

I'm trying to track down how long it would take a Raid 50 array to rebuild. It would consist of two 7 disk Raid 5 sets with Raid 0 tacked on the end. 15k 6Gb/sec SAS drives. Each disk is 600 GB. Even ...

I'm curious if there's a consensus on when is the better time to rebuild a RAID array that suffers a failed drive during peak usage hours. Perhaps I'm luckier than most in that an unscheduled outage ...

Apple offers a couple of software RAID solutions for people interested in either creating a larger disk out of two, or mirroring two disks together for data redundancy in the event of a drive failure.

The history of RAID can be regarded as the history of redundancy due to data distribution. In the figure, green represents the parity that protects the data, and yellow represents the hot spare that ...

Today, we continue our discussion of RAID 5. When it comes to RAID 5, rebuild times are affected by four things. The first parameter is the number of drives in the array: the more drives you have, the ...

In this video, Mark Henderson and Mike Pehlan from NetApp demonstrate how Dynamic Disk Pools enable performance, efficiency, and scalability. Watch as they cause a double-drive failure on two separate ...

Disk Utility provides features for creating disk images, RAID, and repairing disks. In the second part of our deep dive, we'll look at those options. In part 1 of this series, we looked at the basics ...

Use an Nvidia graphics card as a RAID controller – that’s the idea of SupremeRAID from US startup GRAID. For less than $4,000, it can control 32 NVMe SSDs and achieve read throughput of 110GBps and ...
