Product Information

Full Description


Serial Attached SCSI is the logical evolution of SCSI, including its long-established software advantage and the Serial ATA electrical and physical connection interface. With enterprise storage requirements escalating and becoming more complex, factors such as larger capacity, greater density, security, scalability and accessibility are more critical than ever. Enterprise data centers must be online all the time, fulfill requests from numerous users simultaneously, allow for constant growth and expansion and be maintained while in operation. Serial Attached SCSI meets all these demands while providing the highest performance.

Ask a Question

  • The part numer on this drive is -B21 can you tell me the difference between this and -033 suffix?As the drive that has died is a -033

    Thank you for your question. We don't recognise -033 as a valid drive suffix but if you're able to advise which server or other device the failed drive is from, we can certainly advise on a suitable replacement for you. Please email our sales team - sales@kingofservers.com.

  • How are your prices so low?

    At King of Servers we conduct regular price checks to maintain an up to date view on our pricing in relation to our online competitors. We aim to ensure our products are always priced as keenly as possible across our entire catalogue.

    Since it’s impossible to keep tabs on everyone, we offer a Price Match Challenge . If you find a better price elsewhere, we'll do our very best to match it.

    We're not as big as some of our competitors so we have to try harder to win your business and this means offering better prices and better service levels. We’re also fortunate to have smaller overheads than some of our larger competitors and this, coupled with our buying power allows us to secure volume related discounts from our established global network of suppliers. These savings are ultimately reflected in the prices of our products.

    Cheaper doesn't always mean better though, read our blog and watch out for the common pitfalls
