## Parts on hand
| Part | Qty | Form factor | Where it fits | Gain |
|---|---|---|---|---|
| 32 GB DDR5 SODIMM | 2 | SODIMM | **media only** | 32 → 64 GB, its board maximum |
| 2 TB NVMe | 1 | M.2 2280 | media's freed M.2 | +2 TB fast local |
| 1 TB NVMe | 2 | M.2 2280 | utility, cloud, or toc | replaces a 512 GB, needs migration |
| 16 GB DDR4 SODIMM | 4 | SODIMM | **nowhere** | cold spares only |
Status as of 2026-08-15.
The DDR4 has no home. data, utility and cloud each already run 2 × 16 GB DDR4-3200; data and utility are hard-capped at 32 GB, and cloud would need 32 GB sticks to gain anything. toc's two empty slots take **full-size DIMMs**, not SODIMM. Keep them as field spares for the three ThinkCentres.
| Part | Qty | Form factor | Disposition |
|---|---|---|---|
| 32 GB DDR5 SODIMM | 2 | SODIMM | **INSTALLED** in media — 32 → 64 GB, board maximum reached |
| 2 TB NVMe (WD Green SN350) | 1 | M.2 2280 | **INSTALLED** in media as VG `tank` → `/mnt/nvme2tb` |
| 1 TB NVMe | 1 | M.2 2280 | **used elsewhere** — moved into a laptop |
| 1 TB NVMe | 1 | M.2 2280 | **spare, earmarked for utility** (no date set) |
| 16 GB DDR4 SODIMM | 2 | SODIMM | **used elsewhere** — moved into the same laptop |
| 16 GB DDR4 SODIMM | 2 | SODIMM | spare |
| 512 GB Intel NVMe | 1 | M.2 2280 | spare — pulled from media, 0% wear, 9,791 hrs, holds a 2022 BitLocker Windows install |
| 16 GB DDR5-4800 ADATA SODIMM | 2 | SODIMM | spare — displaced from media |
Freed by the media work: one 512 GB Intel NVMe (0% wear, 9,791 hrs) and two 16 GB DDR5-4800 ADATA SODIMMs.
**Why utility is the target for the remaining 1 TB:** it has the fullest thin pool in the fleet (45% vs cloud's 23%) and the fastest-wearing drive — a 512 GB WD SN740 at **12% life used with 85 TB written in only 3,459 hours**, roughly 166 full drive-writes. Its single M.2 holds the boot drive, so this is a clone-and-swap, not an add. Its empty 2.5" SATA bay cannot take an M.2 drive.
The DDR4 SODIMMs had no home in the fleet — data, utility and cloud all already run 2 × 16 GB and the first two are hard-capped at 32 GB, while toc's empty slots need full-size DIMMs. Two went to the laptop instead.
