SCSI Host Adapter - Types

Types

SCSI host adapters traditionally fall into two broad classes:

  • Simple, relatively low-performance cards that provide an inexpensive way to connect SCSI devices that do not demand a great deal of bandwidth: notably CD-ROM drives and SCSI scanners. The cost varies but is typically in the order of $US40 or so. These were very common up until about 2000, but are now fairly rare: the demise of the ISA slot added a little to the cost; the great improvement in IDE technology (particularly in the case of CD-ROM drives and CD recorders) removed one major use, and the advent of USB made the expense of a SCSI interface unnecessary for most scanners.
  • High-end cards designed for maximum performance, usually for very high-speed hard drives, and especially for situations that require several high-speed drives (notably servers). These are almost always quite expensive, around $US200 or more. The advent of serial ATA is expected to reduce the usage of high-end SCSI host adapters, but there is no current expectation that they will disappear in the near future.

Famous quotes containing the word types:

    “The American man is a very simple and cheap mechanism. The American woman I find a complicated and expensive one. Contrasts of feminine types are possible. I am not absolutely sure that there is more than one American man.”
    —Henry Brooks Adams (1838–1918)

    “Our children evaluate themselves based on the opinions we have of them. When we use harsh words, biting comments, and a sarcastic tone of voice, we plant the seeds of self-doubt in their developing minds.... Children who receive a steady diet of these types of messages end up feeling powerless, inadequate, and unimportant. They start to believe that they are bad, and that they can never do enough.”
    —Stephanie Martson (20th century)

    “Our major universities are now stuck with an army of pedestrian, toadying careerists, Fifties types who wave around Sixties banners to conceal their record of ruthless, beaverlike tunneling to the top.”
    —Camille Paglia (b. 1947)
