WD Red Pro hard drive, 4TB NAS, 3.5", 256MB, 7200RPM - WD4006FFBX

WD Red Pro 4TB is a hard drive specifically aimed at NAS systems, where stability and 24/7 operation are more important than anything else. The form factor is standard 3.5", with platter rotation of 7200 rpm and a SATA3 6 Gb/s interface, making it easy to integrate into most cases and NAS enclosures. With 4TB capacity, you have enough space for backups, a file server, a media library, or a small office NAS. Add to this 256 MB cache and you get a drive that performs stably under multiple simultaneous requests.

What you get

This WD Red Pro is designed for NAS environment workloads, where there are often several users reading and writing in parallel. Transfer speed up to 217 MB/sec helps with large copies – for example, transferring archives, 4K video, or large project files to a server. 256 MB cache memory reduces delays when handling many small files, which is typical for shared folders and backup software. 7200 rpm provides faster access compared to typical 5400 rpm NAS drives, which is noticeable when browsing large directories or working with large libraries. The dimensions 26.1 x 101.6 x 147 mm are standard for 3.5" and allow mounting in most cases, racks, and NAS chassis without surprises.

• 4TB capacity – enough for a serious home NAS, media server, or small office file server with years of history.
• NAS hard drive type – oriented towards 24/7 operation and multi-user access, which is key for a stable NAS.
• 7200 rpm – higher rotation speed for faster data access and better response to numerous small requests.
• SATA3 6 Gb/s interface – standard and compatible with almost all motherboards and NAS devices.
• Transfer speed up to 217 MB/sec – helps when working with large files, backups, and fast data recovery.
• 256 MB cache memory – supports smooth operation during parallel operations and with many small files.
• 60-month warranty – 5 years of peace of mind, which is important when your drive holds critical data.

Who it is suitable for

WD Red Pro 4TB is a good choice if you are building or expanding a NAS for home, a small office, or a studio, where there is constant access to files – backup, shared projects, media library. It is also suitable for a file server in a smaller business, where stability and capacity are more important than the absolute peak speed of an SSD. If you are looking for a drive for a main system drive in a gaming machine or workstation with maximum response, it is better to combine it with an SSD for the operating system.

The combination of 4TB capacity, 7200 rpm, large 256 MB cache, and 5-year warranty makes this WD Red Pro a very reasonable base for a reliable NAS solution that you will not think about replacing soon.
