More Info...

Buffalos Technology's new LinkStation 421DE is the next generation two bay NAS enclosure: the 421DE comes in a sleek grey chassis and features easy setup, a new intuitive interface, and a free personal cloud for remote access from anywhere via web browsers or smart devices.

Buffalo's new LinkStation has the latest CPU with a new generation Dual Issue CPU core for noticeably improved performance that delivers very fast transfer speeds - up to 100MB/s. And when fully populated the LinkStation 421DE can be configured in RAID 0 for performance or RAID 1 for redundant storage as part of a back-up solution

Not only will users be impressed with the speed of Buffalo's new LinkStation 421DE they will also appreciate our new intuitive interface. With quick and direct access to settings, and optimised content presentation, the LinkStation 421DE smoothly guides users through easy set up and administration. From the default landing page users will find quick links and toggles to commonly used features which have better wizards, explanations, and graphics; and suddenly NAS administration is no longer the chore it once was

New NAS users will appreciate consolidating their media files and data in one central location; and current NAS users will appreciate faster transfer speeds, expanded capacity, and more features. All users will appreciate Buffalo's free personal cloud for remote access via smart devices or web browsers keeping all your data at your fingertips no matter where you are

Buffalo Technology's LS421DE provides highly customisable network attached storage with greater flexibility. Users can start by installing one drive and add another - when and if needed - to easily increase your network's capacity and capability.

We're happy to announce that if you spend £99 or more we can offer you credit over 6 or 12 months, and if you want a bit longer to pay we offer a 24-month option.

To apply for finance it's really simple, here's our 4-step process

  • Choose your product and add to basket
  • Select PayPal Credit in the basket
  • Complete the easy application

It really is as easy as that! In less than 10 minutes you can have your confirmed delivery date.

Enter your order total:

Representative Example

  • Purchase rate p.a. (variable)


  • Representative APR (variable)

    17.9% APR

  • Assumed Credit Limit


This represents the typical costs of using a PayPal Credit limit, not including instalment offers. The rate of interest that applies to your order is defined by the option you select, we offer plenty of credit options that are interest free and you will not pay interest on at all. This example is based on your using PayPal Credit in future purchases either from us or other retailers.


Am I eligible for finance?

The short answer is, you probably are! Our credit provider carries out credit checks and has a few requirements for offering finance but please make sure you meet these simple requirements

  • Your order is £99 or more
  • You are 18 years or older
  • You are a UK resident, and have been for more than 3 years
  • You can make regular direct debit payments
  • You are in regular employment, or permanently live with a spouse who is in regular employment
  • Have a credit/debit card in your name that is registered to your current address
  • You have a good credit history, and have received no CCJs

How long does it take to apply?

That depends how fast you can type! There are no lengthy applications to complete, you're just asked a few short questions and you can get an instant decision.

What details should I have to hand?

You don't need much - if you already have a PayPal account then usually you'll just have a few questions to answer, if you don't have a PayPal account you just need to register with them.

What if I am declined for finance?

When you're applying for finance you always need to remember that there is a possibility you will be declined. This can often be caused by one of a number of reasons, but usually it will be caused by a negative credit score or a default on an existing loan. We've done our best to make it as easy as possible for our customers that aren't successful in applying to continue their order and pay by Credit Card, Debit Card, PayPal Wallet or Bank Transfer - it really is as simple as clicking "complete my order using a different method". And as always, if you have any concerns please do get in touch.
