SSD vs HDD RAID in Servers and Storage

SSDs in servers deliver performance, whether measured in IOPS or GBps or latency, that is just plain impossible with disks. SSD capacity is now greater than that of performance disks. Price is the factor that still keeps many organizations away from deploying servers with SSD storage when the improved performance is not a significant benefit. The better reliability of SSD might be more important. Continue reading SSD vs HDD RAID in Servers and Storage

Spinning Rust is (almost) Dead, Part 2, Disk Drive Physics

That brings us back to spinning rust. To understand the limitations of rotating hard disk drives, it is important to understand the technology.  With a basic grasp of how a disk drive works, the mechanical limitations  quickly become obvious. If you are accessing data sequentially in big long chunks, where the disk can read an entire track, move over just one track and read Continue reading Spinning Rust is (almost) Dead, Part 2, Disk Drive Physics
