Capacity and interface
The Dell 55H49 is a 3.5 inch internal hard drive with a 3TB capacity and a SAS 6Gb/s interface. It operates at a 7.2K rotational speed for consistent data throughput. This drive is intended for desktop systems or servers that require a SAS connection and a large-form-factor bay.
Upgrade path
The drive replaces an existing SAS hard drive of lower capacity or slower spindle speed in a compatible LFF bay. The jump is worth it when the current storage limit prevents further data growth or when a faster 7.2K drive improves access times for sequential workloads. Systems already using SAS backplanes integrate the drive without controller changes.
SAS practical limits
The SAS 6Gb/s link caps the maximum theoretical transfer rate at the interface level. Real-world sustained throughput is lower and depends on the mechanical 7.2K platters and the host controller implementation. The large 3.5 inch form factor requires a dedicated LFF bay and will not fit in 2.5 inch or small-form-factor chassis.
Highlights
- 3 TB capacity stores large data sets
- 2K RPM spindle delivers steady throughput
- SAS 6 Gb/s interface connects to enterprise controllers
- 5-inch LFF form factor fits standard server bays

Questions about this item
Does the 3.5" LFF SAS drive fit a standard 3.5-inch drive bay?
Yes, the 3.5-inch large form factor matches standard 3.5-inch internal drive bays and uses the SAS interface for connection.
How is the drive installed and what step is often missed?
Slide the drive into the bay, secure it with screws, then attach both the SAS data cable and the power connector; the power connector is the step most often missed.
When will the 7.2K rpm mechanism need replacement?
Mechanical drives with 7.2K rpm spindle speeds typically show wear after several years of continuous use; monitor SMART data and replace if reallocated sectors or seek errors appear.
