WD Green is basically same as Blue, but it lacks a bit of performance. However, it is the most eco-friendly HDD, and it’s quite cheap. WD Blacks are for pure performance including gaming, media, and content creation. Also one of the most expensive HDDs. WD Red is a NAS drive. It’s optimized for NAS systems. WD Purple is for surveillance. Advised for 24/7 operation. WD Gold, probably the most premium of all. Made for a multitude of Datacenter-specific applications. ## Frequently Bought Together - Western Digital 4TB WD Purple Surveillance Internal Hard Drive HDD - SATA 6 Gb/s, 256 MB Cache, 3.5" - WD43PURZ - Amcrest NV4108E-A2 4K 8CH POE NVR (1080p/3MP/4MP/5MP/8MP) POE Network Video Recorder - Supports up to 8 x 8MP/4K IP Cameras, 8-Channel Power Over Ethernet Supports up to 10TB HDD (Not Included) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/536147371-purple-4tb-surveillance-hard-drive-sata](https://www.desertcart.sg/products/536147371-purple-4tb-surveillance-hard-drive-sata) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-11-02*
