Scope
Use this Family for enterprise SATA or SAS solid-state requirements with a defined platform and condition expectation.
Request preparation
Share platform, interface, capacity, form factor, OEM or manufacturer reference, firmware context, carrier requirement, quantity, and traceability needs.
Technical parameters and selection boundaries
Published configurations differ by manufacturer and exact part number. These are selection dimensions, not one combined specification.
| Parameter | Documented example or choice | Verify for this request |
|---|---|---|
| Interface and enclosure | FORESEE UNCIA 3856 examples use SATA III in a 2.5-inch enclosure. | These are SATA examples only. SAS products require their own controller, backplane and exact drive specification. |
| Dimensions | 100.20 × 69.85 × 6.80 mm for the named examples. | Confirm carrier, connector position, mounting and bay clearance; a nominal 2.5-inch label does not establish fit. |
| Capacity and NAND | 480 GB and 960 GB examples use supplier-described 3D eTLC NAND. | Capacity, endurance grade and firmware belong to the complete MPN; do not substitute a different capacity without review. |
| Sequential performance | The named rows list 560 MB/s read and 520 MB/s write at a 128 KB transfer size. | Published manufacturer figures, not a guarantee in every workload. Queue depth, steady-state condition and platform need confirmation. |
| Random performance differs by variant | 4 KB read: 95K IOPS. Write: 40K for RSYE3856N-480G, 45K for RSYE3856N-960G and 75K for RSYE3856T-480G. | Do not combine the capacity of one row with the performance of another. Test conditions and supplied firmware require confirmation. |
| Endurance grade | The N examples list 1 DWPD; the T example lists 3 DWPD. The supplier table lists a five-year warranty period. | Confirm workload, TBW and the exact endurance/warranty terms. The supplier warranty is not a warranty commitment by this site. |
| Power and thermal limits | Idle below 1.3 W; active below 4 W; case temperature 0–70 °C in the named rows. | Confirm host power, cooling and workload. Case temperature is not inlet-air temperature. |
Standard configurations and project options
| Configuration area | Documented option | Project decision |
|---|---|---|
| Capacity versus write workload | Choose the complete N or T part for the intended workload and capacity. | Endurance tier is a different drive selection, not a field adjustment to a finished SSD. |
| Integration details | Specify the server/backplane, carrier, required firmware, usable capacity and write workload. | SATA/SAS/NVMe labels must remain distinct; compatibility needs the complete platform and drive identity. |
Representative models and configurations
Examples illustrate real product variation. A listed manufacturer or model is not a statement of our stock, authorization, or confirmed availability.
| Manufacturer / series | Published configuration | Important scope |
|---|---|---|
| FORESEE RSYE3856N-480G | 480 GB; 1 DWPD; 40K listed 4 KB write IOPS; SATA III; 2.5-inch 6.8 mm enclosure. | Exact supplier catalog example. Confirm current revision, firmware, platform support and orderability; no stock is implied. |
| FORESEE RSYE3856N-960G | 960 GB; 1 DWPD; 45K listed 4 KB write IOPS; SATA III; 2.5-inch 6.8 mm enclosure. | Exact supplier catalog example. Confirm current revision, firmware, platform support and orderability; no stock is implied. |
| FORESEE RSYE3856T-480G | 480 GB; 3 DWPD; 75K listed 4 KB write IOPS; SATA III; 2.5-inch 6.8 mm enclosure. | Exact supplier catalog example. Confirm current revision, firmware, platform support and orderability; no stock is implied. |
Applications and procurement context
- For a SATA enterprise SSD replacement, match the existing bay and controller, required capacity, write workload, firmware and carrier. A higher write-endurance tier should be selected deliberately from the correct MPN.
Compatibility, current supply, lead time, origin, and acceptance documents must be confirmed for the actual order.
