DELL 7J9RN 4TB SAS enterprise drive
This new Dell 7J9RN hard drive delivers 4TB of storage on a 3.5-inch form factor. It spins at 7200 RPM with a 64 MB buffer and connects through a SAS 6Gb/s interface. The unit ships as a bare drive with a tray designed for PowerEdge servers.
Suited for RAID arrays and bulk enterprise storage
Buyers expanding a SAS-based PowerEdge enclosure or building a high-capacity RAID set will match the 7200 RPM spindle speed and 6Gb/s link. Systems limited to slower interfaces or smaller drive bays cannot use this drive, and workloads demanding SSD latency should consider flash alternatives.
SAS 6Gb/s interface determines compatibility
The drive communicates exclusively over SAS 6Gb/s, so the host controller or backplane must support that exact protocol. A mismatched interface will prevent the drive from being recognised or performing at its rated 7200 RPM speed.

Spørgsmål om denne vare
How much data can the 4 TB SAS drive actually hold once it is formatted in a server?
The drive provides 4 TB of raw capacity; the usable space after formatting depends on the RAID level and file system you choose.
What does the SAS 6 Gb/s interface limit in real-world throughput?
The SAS 6 Gb/s link caps the maximum burst transfer rate at 6 Gb/s; sustained throughput will be lower and depends on the 7200 RPM mechanics.
Will the 3.5 inch drive with its included tray fit a standard PowerEdge bay?
Yes, the 3.5 inch form factor and supplied tray are designed to slide directly into a compatible PowerEdge drive bay.
