Lenovo's current ThinkSystem 24TB server options are 4XB7A93007 for SAS and 4XB7A93008 for SATA. Both are 3.5-inch 7.2K hot-swap 512e options.
The purchase decision is platform qualification first, interface second and price third.
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.
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.
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.

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.
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.
For SAS-standardized drive groups, controller policies or redundancy models that expect SAS, buy 4XB7A93007 and keep the drive group consistent.
No. They have different interfaces and must match the server, controller and drive group requirements.
Neither cited ThinkSystem server option is listed in the SED/FIPS HDD table. DE Series has a separate SED option, 4XB7B13111, for arrays.
No. A 7.2K nearline HDD is not normally limited by 6Gb/s SATA for sequential transfer.
