4XB7A93007 is Lenovo's ThinkSystem 3.5-inch 24TB 7.2K SAS 12Gb hot-swap 512e HDD option for qualified server configurations.
Buy it as a ThinkSystem server option. A DE Series 24TB array drive or a generic 24TB SAS mechanism is not automatically interchangeable.
Use 4XB7A93007 when a Lenovo ThinkSystem server and controller path explicitly support the 24TB SAS option. Verify ServerProven, carrier, firmware and sector format before ordering.
Verify the part number, carrier, firmware, sector format and server or storage-array qualification before ordering. A bare mechanism or third-party compatible listing can be useful, but it is an alternative unless it is sold as the qualified OEM kit or spare you need.
These are the verified procurement identifiers and configuration constraints that should survive from quote to purchase order.

Workload rating is recorded per part number from the manufacturer's published data for that exact model where available, not blanketed across the line — two drives of the same capacity can differ because they are different generations. A dash means the figure is not stated for that listing. Recording technology comes from the manufacturer's published CMR/SMR list; a model absent from that list is shown as UNVERIFIED rather than guessed. Rows priced above 3× this line's in-stock median are flagged and excluded from the winner callout and from every median we compute.
This table is computed from live DatacenterDisk rows when an exact in-stock match exists. It is intentionally blank for unavailable models rather than filled with stale prices.

These are procurement paths to evaluate when exact stock is absent. Alternatives still require the exact platform, controller, sector format, carrier and support policy to approve them.
| Alternative | When it can work | Procurement warning |
|---|---|---|
| 4XB7A93007 | Best replacement path for a ThinkSystem server drive group that requires the Lenovo 24TB SAS option. | Do not treat a DE Series part or bare SAS drive as the same option. |
| 4XB7A93008 | SATA capacity alternative when the server, controller and drive group qualify the SATA option. | Not a SAS dual-port or SAS-controller substitute. |
| Lower-capacity Lenovo ThinkSystem SAS option | Possible stopgap when the server qualifies it and capacity requirements allow a smaller drive. | Mixing capacities can reduce usable RAID capacity or complicate spares. |
| Generic 24TB enterprise HDD | Only where the support policy accepts non-Lenovo drives. | No ThinkSystem carrier, firmware or ServerProven status by default. |
Use this table before accepting a quote, especially when new, open-box, refurbished and bare-drive listings appear side by side.
| Check | Why it matters |
|---|---|
| Exact option | 4XB7A93007 must appear on the quote or listing when you need the exact OEM option. |
| Carrier | ThinkSystem server carrier option |
| Firmware path | OEM-qualified firmware can decide update eligibility, health reporting and support handling. |
| Sector format | 512e must match the controller, array and existing drive group. |
| Condition | New, open-box, refurbished and used units should be compared as different offers, not as the same price point. |
| Support | Handled through Lenovo option/server support terms |
Raw decimal capacity is shown before filesystem formatting, RAID, hot spares, snapshots or vendor overhead.

Lenovo Press identifies 4XB7A93007 as a ThinkSystem 3.5-inch 24TB 7.2K SAS 12Gb hot-swap 512e HDD. That is enough to distinguish it from the SATA sibling 4XB7A93008 and from DE Series array options.
Lenovo ServerProven and current product guides show support in selected V3/V4 ThinkSystem servers, but the final answer still depends on the exact server, bay layout, backplane and controller.
The cited HDD Reference lists 4XB7A93007 outside the SED/FIPS HDD group. Do not buy it for an encryption requirement without verifying a separate SED option.
No. Lenovo identifies 4XB7A93007 as the 24TB SAS 12Gb hot-swap 512e ThinkSystem option.
No. It is a ThinkSystem server HDD option, not a DE Series storage-array option.
The cited Lenovo HDD Reference does not list this part in the SED/FIPS HDD section.
