3.84 TB enterprise SSD with SATA interface delivering 520 MB/s read and 480 MB/s write, rated 1.3 DWPD with power-loss protection
The Dell 09Y3HD is a 3.84 TB enterprise solid-state drive with a SATA 6 Gb/s interface and a 2.5 inch form factor. It ships installed in a hybrid tray that fits 3.5 inch bays and is rated at 1.3 DWPD endurance with a 2,000,000 hour MTBF. Features include end-to-end data protection, power loss protection, thermal monitoring protection and AES 256-bit hardware encryption. Sustained sequential read reaches 520 MB/s and write reaches 480 MB/s.
This drive suits data centres running enterprise NAS, DAS, backup, archiving, cloud or big-data analytics on compatible PowerEdge 14G, 15G and 16G rack servers with 3.5 inch chassis. It is not suited for write-heavy workloads that exceed the 1.3 DWPD rating or for systems that require a native 3.5 inch drive without a tray adapter.
The single specification that decides fit is the SATA 6 Gb/s interface combined with the 1.3 DWPD endurance rating. Buyers must confirm their server backplane supports SATA and that the workload stays within the rated write endurance.

The drive ships pre-mounted in a Dell G14 hybrid tray X7K8W that converts the 2.5-inch SSD to a 3.5-inch form factor; the step often missed is fully seating the tray until the latch clicks into the server backplane.
With an endurance rating of 1.3 DWPD and a 2,000,000-hour MTBF, the drive itself requires no scheduled maintenance; replacement is only needed when the write endurance limit is reached or a SMART alert indicates wear.
The sustained sequential write speed caps at 480 MB/s, and the 1.3 DWPD endurance rating means the write budget will be exhausted before the SATA 6Gb/s interface becomes the bottleneck.
