The same family also carries 11 assembly revisions, 15 OEM drive models, two generic part numbers and one alternate part number, all listed in the cross-reference block on this page.

Does EG0300JFCKA come with a caddy?
Yes. The hot-swap tray is included and attached to the drive. It is a 2.5-inch small form factor hot-plug drive intended for server and storage unit bays, measuring 0.591" high and 2.75" wide. Because the carrier is already fitted, no separate caddy purchase is needed for the supported chassis listed on this page, provided the bay accepts this carrier type.
What interface and performance does EG0300JFCKA provide?
EG0300JFCKA is a 300GB SAS (Serial Attached SCSI) hard drive with a dual port connection and a 6 Gb/s external data transfer rate. It spins at 10,000 rpm. The dual port design allows two paths to the drive, which is used for redundancy in supported controller and enclosure configurations. It is classified as a SAS storage device and requires a SAS controller or backplane.
