Uncompromising Storage with a WD Purple Surveillance Hard Drive
WD Purple drives are engineered specifically for surveillance to help withstand the elevated heat fluctuations and equipment vibrations within NVR environments. An average desktop drive is built to run for only short intervals, not the harsh 24/7 always-on environment of a high-definition surveillance system. With WD Purple, you get reliable, surveillance-class storage that’s tested for compatibility in a wide range of security systems, and some of our latest models (WD22PURZ, WD42PURZ, and WD63PURZ) have improved power efficiency. Exclusive AllFrame™ technology helps reduce frame loss and improve overall video playback.

Western Digital's Exclusive AllFrame Technology
All WD Purple drives are equipped with AllFrame technology, which improves ATA streaming to help reduce frame loss and improve overall video playback, within a multitude of security video solutions.

Enhanced Workload Ratings
WD Purple™ drives feature a workload rating of up to 180TB/year2 - up to three times that of desktop drives - to handle the unique demands of mainstream video surveillance DVR and NVR systems.

Multiple Cameras, Multiple Streams
Modern recorders now support multiple video streams per camera. WD Purple drives support up to 64 single-stream HD cameras (6TB1 and above), and can also support many of the latest cameras that transmit multiple streams to enable basic AI functionality. With so many options, you have the flexibility to upgrade or expand your security applications in the future.

Designed for Today's and Tomorrow's Surveillance Solutions
With an MTBF of up to 1 million hours3, WD Purple drives are engineered for mainstream surveillance DVRs and NVRs that operate 24/7. With tarnish-resistant components3 and support for more than eight bays4, WD Purple drives deliver reliable operation even in harsh environments.

Not the quality or color combination I expected for the price, returns are not guaranteed
Color: 4 Panels Natural, Size: 4 Panels, Color: 4 Panels Natural, Size: 4 Panels
I was really looking forward to receiving this room divider as I loved the top design (unique compared to other "square" room divider tops), but sadly this was a dud. I really wanted to like this, but the finishing/quality, wood color, and rattan/bamboo coloring just did not work for me. It was packaged very well (so that earned some stars back), but for the price it did not meet expectations on quality. The wood itself is discolored in different places (beyond just "vintage" - it looked strange with random red-wood boards on the slatting on the bottom rather than truly tan wood color) and on the sides you can see it was made out of cheap plywood (with the multiple layer lines clearly showing). While I know it's supposed to be a rustic wood look, the way that pieces were joined and the direction of the grain just looked cheap and overly unfinished in my opinion. The rattan was very yellow compared to the wood and the plastic pieces - what confused me the most was that the product images show the "window crossbars" as the back of the room divider, and if that's the case, then the front shows really ugly plastic trim around the rattan. Perhaps the darker brown would have been a better choice, or ultimately a painted white one, but in general I'm really bummed the natural color one wasn't what I was hoping for. ALSO beware the seller is 3rd party, so you have to work directly with the seller to be able to return it and they will ask for photos to explain why you don't like it. If you buy, be prepared to potentially not be able to return it if the seller doesn't want to accept your return request.

Solid Floating Shelves 🛠️🏠
Color: Black, Number Of Shelves: 4, Size: 15.7in
I have installed four sets of the black floating shelves in my office. They are made of high quality materials, featuring a sophisticated black woodgrain finish with a natural texture. Supposedly, each unit can handle up to 22 pounds, though I would not recommend testing that limit with your vintage bowling ball collection if you value your flooring. They are awesome. The value is good for a set of two. Each shelf measures 22x7x1 (56x17x3 cm) inches, providing a decent amount of storage for books or decor. The installation was straightforward since the hardware for multiple wall types was included. They work well in the kitchen for spices or in the bedroom for personal belongings. One tip for a secure fit: use a level during installation and make sure the bracket is flush against the wall before sliding the shelf on, or your photos might look like they are sliding off a mountain 📐 These shelves offer a clean, modern look and stay stable once mounted correctly. They are a practical choice for adding functional display space to any room 🖼️

Good looking shelves and easy install - skip the included drywall anchors
Color: Black, Number Of Shelves: 2, Size: 22in
I installed these shelves in a bedroom to get things off my dresser and some decor. Once mounted they look really nice. The black finish looks clean and modern and they blend in well with the room. Installation was pretty straightforward. The metal bracket mounts to the wall first and then the shelf slides over the bracket. As long as you take your time lining things up it’s a simple project. One thing I strongly recommend is not using the white plastic self-drilling drywall anchors that come with the kit. I’ve used that style before on other projects and they tend to strip out easily and leave larger holes in drywall. I used better anchors instead and the shelves mounted much more securely. The rest of the hardware worked fine and once installed the shelves feel solid and hold items well. Pros - Clean modern look - Easy installation - Feels solid once mounted - Good size for books or decor Cons - The small level included isn’t very accurate — use your own level - One of the metal brackets was slightly bent out of the box but straightened out easily Helpful tip: Use your own level and better drywall anchors if you have them. It makes installation easier and the shelves will mount much more securely. Final thoughts: For the price these are nice looking floating shelves that install easily and work well for light storage and decor.
