Quick answer

Choose 4XB7A93007 SAS when the ThinkSystem controller path or redundancy design requires SAS. Choose 4XB7A93008 SATA when the server qualifies it and the workload is capacity-first nearline storage.

Choose by ThinkSystem configuration
OEM procurement check

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.

The interface headline is only one line item. Qualification, carrier, controller and firmware path decide whether the drive is actually buyable for your system.

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.

Live acquisition math for exact comparison rows

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.

No exact in-stock row is available right now. Use the availability table for nearby live alternatives, then re-check the exact model before ordering.

Interface is not the only difference

SAS and SATA options may go through different controller, firmware and spare processes even at the same capacity. Keep the server qualification path in the purchase record.

When SATA is the practical answer

For backup, archive and object-capacity servers, qualified SATA often provides the better price and enough real throughput. The mechanical drive is the limiter, not the 6Gb/s link.

When SAS is the practical answer

For SAS-standardized drive groups, controller policies or redundancy models that expect SAS, buy 4XB7A93007 and keep the drive group consistent.

Frequently asked questions

Are 4XB7A93007 and 4XB7A93008 interchangeable?

No. They have different interfaces and must match the server, controller and drive group requirements.

Which Lenovo 24TB option is SED?

Neither cited ThinkSystem server option is listed in the SED/FIPS HDD table. DE Series has a separate SED option, 4XB7B13111, for arrays.

Does 12Gb/s SAS mean twice the performance?

No. A 7.2K nearline HDD is not normally limited by 6Gb/s SATA for sequential transfer.
