How fast is a hard disk drive? How about the various flavors of SATA and Fibre Channel? Check out this handy Pack Rat infographic to answer the question, “how fast is it?”
Computer History
Considering the history of computing, from the enterprise to the home.
Flexible IT and the Path to the Services Future
I’m an IT revolutionary. I talk all the time about the quaint backwards “state of the art” in enterprise IT, what with its (many) decades old protocols, paradigms, and practices. What we call modern is really just a charade of faked-out old-fashioned open systems infrastructure: Pretend servers talking to fake disks over frankenstein networking technology.
The Four Horsemen of Storage System Performance: I/O As a Chain of Bottlenecks
It is tempting to think of storage as a game of hard disk drives, and consider only The Rule of Spindles. But RAM cache can compensate for the mechanical limitations of hard disk drives, and Moore’s Law continues to allow for ever-greater RAM-based storage, including cache, DRAM, and flash. But storage does not exist in a vacuum. All that data must go somewhere, and this is the job of the I/O channel.
From CAS to Cloud: Revolutionary Storage
Change is not a word normally associated with storage, and revolution is practically unheard of. Today’s modern enterprise storage systems and networks employ massive resources to do one simple thing: Emulate the basic hard disk drives used over three decades ago. But cracks are appearing in our mausoleum of fake disks: Application developers are discovering the value of object storage, and storage systems are appearing to support this need.
Forecasting Seagate’s Next-Generation Momentus 5400.8 Family
Seagate is one of the world’s most-successful hard disk drive companies, consistently ranked first in overall sales for a decade. The company is respected for their high-end products, but is aggressively moving into the world of smaller hard disks for laptops and portable storage as well. The company’s mainstream “Momentus” portable hard disk family has kept pace with the industry, but Seagate will soon break away with a major jump in areal density. Using public information, and the first product in this line, we will consider what Seagate’s eighth-generation Momentus family will look like.
