How to expand you Mac or Windows PC with an External PCIe Expansion Box

Think outside the Box with PCIe Expansions

akitio-thunder2-pcie-box-angleopen-highres Stepping away from the subject of Storage and Backups, another decision you may have to make will be whether to invest your budget into a high-end Desktop setup or a more fluid, portable operation. Traditionally the problem has always been that portable operations via a Macbook, Laptop or Tablet are plagued by Hardware limitations. Not now though. With innovations in Thunderbolt and PCI Express Expansion technology, you can now install Upgrades and Hardware intended for Desktop setups in a highly portable PCIE expansion chassis. Need 4GB Graphics Card power in your Mac book – no problem. Large channelled Sound card – easy peasy.

Whilst not as well known as Sonnet, they have been pioneering the PCIe Expansion market for a number of years with their early ‘TurboBox’ unique SAS range, available in both Desktop and MacBook / Laptop versions. Their latest products have been fully harnessing the Thunderbolt and Thunderbolt2 market. Definitely a contender in the PCE-Express stakes. Take a look at the pick of the litter below:

Both have been around for a long time in a multitude of fields within Data storage, but have only recently decided to enter the PCIe market. Don’t be put off by their relatively thinner product range in PCI-E circles though, both come with high reviews and highly adaptable products. Both are Mac (OSx) and Windows compatible. Take a look below and see what we think stands out.

Pro Tip – PCI-Express cards comes in a variety of speeds and physical sizes. Always check that the expansion you are considering can accommodate the card you have in mind. Look at:

1. Speed – Is it x4, x8, x16? Make sure you buy a PCIE expansion that can accommodate your Card’s speed level Such as The Netstor NA211TB which supports all the way upto 16x.

2. Profile – Think of this as the Width. If your PCI-E card is not Low Profile, make sure the expansion can house it correctly – the reverse is also true.

3. Height – Whether your card is Half Height or Full Height is also an important consideration. Particularly if you plan on housing more than one card in your expansion. Some units will either house 2 Half-Height or 1 Full-Height…not both!
