Does the Lenovo ThinkPad T420s Take an NVMe SSD?
Lenovo ThinkPad T420s
Every one of 112 field reports observed SATA storage rather than NVMe.
That is useful evidence about the reported machines, but it does not prove that every configuration lacks an NVMe slot or that the installed SATA drive is 2.5-inch rather than SATA M.2. Check the service manual, connector, dimensions, and current drive before ordering.
Field reports can’t tell us whether the SATA drive is a 2.5-inch bay or a SATA M.2 slot, nor which M.2 length fits — check the service manual before you buy.
Reported by field data
- Storage controller:
- Intel Corporation 6 Series/C200 Series Chipset Family 6 port Mobile SATA AHCI Controller
- Platform:
- Intel Corporation 2nd Generation Core Processor Family DRAM Controller
- Drives seen:
- INTEL SSDSA2BW16, Samsung SSD 850, Samsung SSD 860
Drives people actually had installed when they ran the report — not a compatibility list, and not the only drives that fit.
Capacities seen
- 500 GB (37%)
- 128 GB (27%)
- 160 GB (20%)
- 250 GB (17%)
Sizes found installed in field reports — not a ceiling. Larger drives work fine.
How we know
This answer is derived from 112 independent hardware reports for the Lenovo ThinkPad T420s, of which 0% observed an NVMe drive. We read the PCI device list in each report to tell NVMe apart from SATA.
