I don't see it in the product description.** A: I had an issue with some of the WD Red drives I had purchased through Amazon... I had a failure and contacted WD for replacement under warranty... I was told that the drive I had only had a one year warranty period not the three year. The drive serial number started with WD and that indicated it was a drive from a single disk NAS.. those have only a one year warranty Where the other drives carry the 3 year. What is the difference in the drives i can not say or tell from looking at them and no other information was provided by WD. I was told I needed to go back to the seller and see if they would fix the issue. Since I've bought a number of drives over the last three years one at a time and registered them with WD, I didn't mark each drive and could not tell which drive came from what seller since the invoices didn't indicate the serial number of the drives.. I have 4 other drives in that situation. Since it was registered at the time I received the drive I know it was within the 3 years but after the 1 year warranty that WD would support. I had to buy a replacement.. Thing is that all the drive were in WD boxes and sealed in static bags. **Q: Can this drive be installed into an external HD case and used as a single drive media server or does it have to be installed in a NAS case?** A: It's designed for continuous use and not intended to be shut down and restarted on a routine basis. Those that say that they lack the performance of a desktop HD is just not true. they have similar performance characteristics with most 5200 RPM drives. One typically doesn't put a 4TB drive in a PC as a system drive. Usually, you would use a 1 TB drive that are typically 7200 RPM, which does provide better performance. If you really need that much space in your PC (system or otherwise) you're better off not using a NAS drive, something like the Seagate Barracuda. **Q: Why is this more expensive than an external wd 10 tb drive such as: https://www.amazon.com/s?k=wd+10tb+elements+desktop+usb+3.0+external+hard+drive&re** A: The retail storage market is more competitive. NAS and Enterprise drives meet 24/7/365 read write reliability benchmarks and typically have a 3-5 year warranty. Retail consumer drives may in some cases last as long as NAS drives, but typically will have a shorter warranty. Note that liberating a hard drive from a retail external enclosure (to use in a PC) would likely void the drives warranty altogether. **Q: Can this drive be used to replace the internal hard drive within the apple 3tb time capsule?** A: Depends if it uses a 2.5in or 3.5inch drive or not. Specs are probably fine but need to know what size of hard drive it takes. Based on the dimensions of the apple device, it might accommodate this. Based on the apple dimensions, I would be surprised if it uses 3.5in drives but it isn't impossible. ## Frequently Bought Together - Western Digital 4TB WD Red Plus NAS Internal Hard Drive HDD - 5400 RPM, SATA 6 Gb/s, CMR, 256 MB Cache, 3.5" -WD40EFPX - Synology 2-Bay DiskStation DS224+ (Diskless) - Seagate IronWolf 4TB NAS Internal Hard Drive CMR 3.5 Inch SATA 6Gb/s 5400 RPM 64MB Cache for RAID Network Attached Storage Rescue Services (ST4000VNZ06/006) --- ## 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.gr/products/493355095-western-digital-4tb-wd-red-plus-nas-internal-hard-drive](https://www.desertcart.gr/products/493355095-western-digital-4tb-wd-red-plus-nas-internal-hard-drive) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-09-11*
