HP Inc 4L5J9AA Z2 SFF Slim Internal DVD±RW Optical Drive

Overview

The HP 4L5J9AA is a 9.5mm slim internal DVD±RW optical drive designed as a factory-compatible replacement or upgrade option for the HP Inc workstation lineup, specifically the Z2 Small Form Factor (SFF) chassis. At 0.70 lb and 9.10 x 7.50 x 2.40 in, this drive slots into the Z2 SFF's dedicated internal optical drive bay without modification — no adapters, no bracket hunting. If your Z2 SFF shipped without an ODD or you're replacing a failed unit, this is the direct-fit path.

The 9.5mm slim profile is the key dimensional constraint here. Standard desktop optical drives run 12.7mm tall and will not fit the Z2 SFF bay. The 4L5J9AA is built to the 9.5mm slimline specification, which is what HP's compact workstation chassis requires.

Key Features

• DVD±RW Read/Write Support: Handles the full range of recordable DVD and CD formats — DVD+R, DVD-R, DVD+RW, DVD-RW, CD-R, CD-RW. Useful for workstations that still need to image drives, burn recovery media, or access legacy optical archives that haven't been digitized.
• 9.5mm Slim Form Factor: The Z2 SFF chassis uses a slimline ODD bay. A standard 12.7mm desktop drive will physically not fit. The 4L5J9AA is built to 9.5mm, which is the correct spec for this chassis — no modification required.
• Internal Desktop Mount: Installs internally as a dedicated workstation component, keeping the external footprint clean and avoiding the cable clutter and desk-space penalty of an external USB drive. Correct choice when the workstation will stay stationary.
• Black and Silver Finish: The dual-tone color matches HP Z2 SFF cosmetics. Not a critical spec, but worth noting if the chassis has a windowed panel or the bezel will be visible in a presentation environment.
• Lightweight at 0.70 lb: Relevant for system weight budgets in deployments where workstations are rack-mounted or transported, though in a standard desktop installation this is mostly a non-factor.
• Genuine HP Component: Factory-new, genuine HP part — not a gray-market or parallel-import drive. When a Z2 SFF is under active HP Care Pack coverage, using genuine HP parts avoids compatibility disputes during service calls.

Integration & Compatibility

The 4L5J9AA is specifically listed for the HP Z2 SFF workstation platform. Before ordering, verify two things: (1) your Z2 SFF chassis has an unoccupied slimline ODD bay — some configurations ship with a bay cover and no drive fitted; (2) your workstation's BIOS and OS recognize the SATA slimline interface, which is standard on all Z2 SFF generations. Driver requirements are minimal — Windows 10/11 and mainstream Linux distributions enumerate slimline SATA optical drives natively with no additional driver installation.

This drive is not designed for tower or full-size desktop bays. The 9.5mm height and slimline SATA connector are specific to compact form factor workstations. If you are working with an HP Z2 Tower or a different chassis entirely, verify the bay specification before purchasing — a 12.7mm half-height drive is the standard for full-size desktop bays.

Country of origin is CN. UNSPSC commodity code is 43211600 (optical storage drives).

Frequently Asked Questions

Q: Will the 4L5J9AA fit in a standard desktop tower optical bay?

A: No. The 4L5J9AA is a 9.5mm slimline drive built for compact form factor chassis like the HP Z2 SFF. Standard desktop tower bays use 12.7mm half-height drives with a different connector. Installing this in a tower bay would require an adapter bracket and connector adapter, and is not supported.

Q: What optical formats does the 4L5J9AA support?

A: It is a DVD±RW drive, meaning it reads and writes DVD+R, DVD-R, DVD+RW, DVD-RW, and all standard CD formats (CD-R, CD-RW, CD-ROM). It does not support Blu-ray.

Q: Is the 4L5J9AA an internal or external drive?

A: Internal. It installs inside the HP Z2 SFF chassis into the dedicated slimline ODD bay. It is not a USB external drive.

Q: What is the weight and size of the 4L5J9AA?

A: The drive weighs 0.70 lb and measures 9.10 x 7.50 x 2.40 inches (L x W x H).

Q: Does the 4L5J9AA require special drivers?

A: No special drivers are required. Windows 10, Windows 11, and mainstream Linux distributions support slimline SATA optical drives natively through their built-in storage drivers.

The 4L5J9AA comes up regularly when someone is configuring or servicing an HP Z2 SFF and realizes the chassis shipped without an optical drive — or the original unit failed. The 9.5mm slimline form factor is the one spec that trips people up most often: it is not interchangeable with standard 12.7mm desktop drives, and ordering the wrong height means the drive will not seat correctly in the Z2 SFF bay.

Technical Highlights:

• 9.5mm Slimline Height: The HP Z2 SFF ODD bay is built to the 9.5mm slimline spec. This drive fits that bay directly. A standard half-height 12.7mm desktop drive does not — full stop.
• DVD±RW Format Coverage: Handles all current recordable DVD and CD formats. Adequate for recovery media creation, legacy archive access, and occasional disc-based software deployment in environments that haven't fully migrated to USB or network imaging.
• 0.70 lb Weight / Compact Dimensions: At 9.10 x 7.50 x 2.40 in and 0.70 lb, this is a true slimline unit. Useful to know when documenting a workstation's configuration weight for mobile deployments or rack calculations.

Deployment Considerations:

• Confirm the Z2 SFF chassis has an available slimline ODD bay before ordering — some Z2 SFF configurations ship with a blank bay cover and no internal mounting hardware for an ODD. Check the chassis service manual for your specific generation.
• This drive does not support Blu-ray. If the deployment requires Blu-ray read capability (e.g., forensic disc imaging, archival media), this is not the correct drive — verify whether an HP slimline Blu-ray option exists for the Z2 SFF platform.

Best fit: HP Z2 SFF workstations in enterprise IT environments, CAD/GIS workstations, or security operations centers where the compact chassis is deployed and optical media access is still part of the workflow — imaging, recovery disc creation, or reading physical media that predates USB-only software distribution.
