Peak Design is at it again! They’ve kicked off their 9th Kickstarter campaign and it is already a $1.7m success. Peak Design has designed a new Travel Tripod that is intended to revolutionize the tripod — it folds more compactly to minimize dead space and sets up and takes down faster.

In addition to the compact design, the travel tripod features a quick-attaching compact ball head, deployable center column knob, low-profile cam levers, single ring for total head adjustment, and a standard plate that is Arca Swiss compatible.

The Kickstarter campaign is the best way to save on a Peak Design product — save up to 20% vs. the future retail price, and be among the first to receive the new product. Pledging $289 gets you the aluminium Travel Tripod; $479 gets you the carbon fiber Travel Tripod, but only for a limited time. Check out their Kickstarter campaign today.

UPDATE: Deal expired.

Amazon has a super-hot deal on the WD My Book Duo 16TB Two-Bay USB 3.0 Type-C RAID Array (2 x 8TB) — it’s now only $169.99, which is an incredible savings from the $600 list price for this enclosure plus two drives.

It is an amazing deal as WD notes very clearly in the product description: “The My Book Duo drive comes with RAID-optimized WD Red drives inside to deliver high-speed, quality storage to rely on.” That’s right, WD is guaranteeing that two 8TB Red drives are inside — drives that currently retail for $240 each. To get two drives for $170 (each $85) is a steal.

This deal is out of stock and available to backorder (with no estimated ship date) from Amazon, but we have no idea when they will turn off the backorder. The maximum order quantity is 3, which would be perfect for building a NAS. You don’t even need to shuck the enclosure — it’s designed so you can easily take the drives out. Backordering for this deal is a no-brainer.
