Review: This was a great price under $600 and I'm satisfied - I purchased three of these hard drives. One came to me. It didn't function. About a month later I received a new one. Review: A workhorse of a drive. Great for Surveillance Camera Systems! 13 cameras, 3 Years and Counting... - I use two of the 18GB drives for stored video for two Blue Iris security camera systems in different locations. Zero compatibility issues with Blue Iris or two desktops (Lenovo Think Station & HP Elite work station) Both systems write direct-to-disk fast, with one handling 13 cameras, all recording constantly and the other handling 5 continuously. The system with 13 cameras has had the drive running flawlessly for 3 years now and the other with 5 cameras for about 1 year. I have no complaints about the noise level--some say they are a tad loud, but I feel they are reasonable for what they are doing. No problems whatsoever with either drive or system. I highly recommend for constant-write uses such as surveillance systems. The 18GB was overkill for my application but I wanted at least 30 days of backup footage in my system for all cameras and a few more in the future. They're a workhorse of a drive. ## Features - Engineered with advanced capabilities needed for high-end smart video solutions - High performance, reliability and workload capability for advanced AI-enabled recorders, video analytics appliances, deep-learning servers and cloud-based storage - Supports up to 550 TB/yr workload rate**. - Designed with tarnish-resistant components for harsh environments, and with additional robustness for multi-bay enclosures ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0966TBDRZ | | Additional Features | Data Recovery Service | | Best Sellers Rank | #5 in Internal Hard Drives | | Brand | Western Digital | | Built-In Media | 3.5" WD Purple Pro SATA 6 Gb/s Hard Drive, Mounting Screws, Quick Install Guide | | Cache Memory Installed Size | 512 | | Color | Purple | | Compatible Devices | Server, Storage System, Video Surveillance System | | Connectivity Technology | SATA | | Customer Reviews | 4.0 out of 5 stars 493 Reviews | | Data Transfer Rate | 272 megabits_per_second | | Digital Storage Capacity | 18 TB | | Enclosure Material | Information Not Available | | Form Factor | 3.5-inch | | Global Trade Identification Number | 00718037889481 | | Hard Disk Description | Mechanical Hard Disk | | Hard Disk Form Factor | 3.5 inches | | Hard Disk Interface | Serial ATA | | Hard Disk Rotational Speed | 7200 rpm | | Hard-Drive Size | 18 TB | | Hardware Connectivity | SATA 6.0 Gb/s | | Hardware Platform | Western Digital | | Installation Type | Internal Hard Drive | | Item Dimensions L x W x Thickness | 6"L x 4"W x 1"Th | | Item Type Name | Hard Drive | | Item Weight | 1.8 pounds | | Manufacturer | Western Digital Technologies, Inc. | | Mfr Part Number | WD181PURP | | Model Name | WD Purple Pro Surveillance Hard Drive | | Model Number | WD181PURP-SPB6HY0 | | Number of Items | 1 | | Special Feature | Data Recovery Service | | Specific Uses For Product | Business, Personal | | UPC | 718037889481 | | Unit Count | 1 Count | | Warranty Description | Five year limited-warranty | ## Product Details - **Brand:** Western Digital - **Color:** Purple - **Compatible Devices:** Server, Storage System, Video Surveillance System - **Connectivity Technology:** SATA - **Digital Storage Capacity:** 18 TB - **Hard Disk Description:** Mechanical Hard Disk - **Hard Disk Form Factor:** 3.5 inches - **Hard Disk Interface:** Serial ATA - **Installation Type:** Internal Hard Drive - **Special Feature:** Data Recovery Service ## Images ![Western Digital 18TB WD Purple Pro Surveillance Internal Hard Drive HDD - SATA 6 Gb/s, 512 MB Cache, 3.5" - WD181PURP - Image 1](https://m.media-amazon.com/images/I/61iSDo-1aZL.jpg) ![Western Digital 18TB WD Purple Pro Surveillance Internal Hard Drive HDD - SATA 6 Gb/s, 512 MB Cache, 3.5" - WD181PURP - Image 2](https://m.media-amazon.com/images/I/81s0cykrM-S.jpg) ![Western Digital 18TB WD Purple Pro Surveillance Internal Hard Drive HDD - SATA 6 Gb/s, 512 MB Cache, 3.5" - WD181PURP - Image 3](https://m.media-amazon.com/images/I/81gNvA7tOpL.jpg) ![Western Digital 18TB WD Purple Pro Surveillance Internal Hard Drive HDD - SATA 6 Gb/s, 512 MB Cache, 3.5" - WD181PURP - Image 4](https://m.media-amazon.com/images/I/81CH8bvFRvL.jpg) ![Western Digital 18TB WD Purple Pro Surveillance Internal Hard Drive HDD - SATA 6 Gb/s, 512 MB Cache, 3.5" - WD181PURP - Image 5](https://m.media-amazon.com/images/I/81KA9-mKrML.jpg) ## Available Options This product comes in different **Size, Style** options. ## Questions & Answers **Q: Can it be installed vertical instead of horizontal inside my lorex nvr?** A: I don't see any reason why not.

The other was DOA - NVR reported an error and it wouldn't spin up. Eh, no big deal, it happens, I returned it to Amazon and they sent me replacement. This one was ALSO DOA. At this point I wondered if maybe my NVR backplane had an issue, so I tested the drive in other computers; nope, still dead. I switched around my existing NVR drives, and that slot works fine. So, two dead drives out of three. I then came here to check reviews, and I see many 1-star Dead-on-Arrival reviews, with many people apparently not checking until after return period (that sucks!). If you want to take the gamble, just be sure you check your drives right away when they show up! ## Frequently Bought Together - Western Digital 18TB WD Purple Pro Surveillance Internal Hard Drive HDD - SATA 6 Gb/s, 512 MB Cache, 3.5" - WD181PURP - Western Digital 10TB WD Purple Pro Surveillance Internal Hard Drive HDD - SATA 6 Gb/s, 256 MB Cache, 3.5" - WD101PURP - Tripp Lite SMART1500LCD 1500VA Rack Mount UPS Battery Backup, 900W, 8 Outlets, PWM Sine Wave, Short Depth 2U Rackmount UPS, AVR, LCD Screen --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/327939470-western-digital-18tb-wd-purple-pro-surveillance-internal-hard-drive](https://www.desertcart.tn/products/327939470-western-digital-18tb-wd-purple-pro-surveillance-internal-hard-drive) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-06*
