Dell 89Th4 146GB 15K SAS Drive

The Dell 89Th4 is a 146GB 2.5-inch internal hard drive spinning at 15000 RPM with a SAS 6Gb/s interface. It is supplied new with a tray for direct installation in compatible PowerVault servers. This enterprise-class HDD targets administrators who need high-speed rotational storage for transaction-heavy workloads.

Suits PowerVault bays needing 15K SAS

This drive fits 2.5-inch hot-plug bays that accept SAS 6Gb/s devices and require the supplied tray. It is not suitable for systems limited to slower interfaces or larger 3.5-inch form factors. Buyers needing greater capacity per spindle or solid-state latency should evaluate alternative media types.

Deciding spec is the SAS 6Gb/s interface

The controller or backplane must support SAS at 6Gb/s to recognise and run this drive at its rated transfer rate. Without a matching SAS host connection the drive will not function. Confirm the server or enclosure documentation lists SAS 6Gb/s compatibility before purchase.

Questions about this item

Does the Dell 89Th4 ship with a mounting tray or just the bare 2.5" drive?

The unit is supplied as a bare 2.5" drive; the tray shown in some images is not included and must be sourced separately if your chassis requires one.

Why choose the 146 GB 15000 RPM SAS model instead of a larger capacity?

The 146 GB capacity paired with 15000 RPM SAS 6 Gb/s targets workloads that prioritise low latency and high IOPS over raw capacity, such as database logs or transactional volumes.

What real-world throughput can I expect from the 6 Gb/s SAS link on this 15000 RPM drive?

The SAS 6 Gb/s interface supports burst transfers up to the link speed, while sustained sequential performance is determined by the 15000 RPM mechanical design and will vary with workload and controller.
