WD SN5000S 512 GB SDEPTSJ-512G-1012

The SDEPTSJ-512G-1012 is an SN5000S-series 512-GB NVMe SSD first tested by Notebookcheck in Oct 2026. A 22 by 30, PCIe 4 x4 model with QLC flash memory, it comes with no hardware encryption and no RAM for data caching. The series originally launched in Q1 2024. Interestingly enough, the drive we got our hands on in Oct 2026 as part of a Dell laptop review was made in 2024.

Its TBW and peak power consumption figures as stated in the spec sheet are an unremarkable 150 and 6.1, respectively.

Performance

AS SSD gives us 4.90 GB/s for sequential reads and 2.53 GB/s for writes, both pretty far away from the claimed 6.00 and 4.20 figures. The first test unit exhibited very noticeable throttling in a read stress test, too. This is a lower-mid-range PCIe 4 SSD as its performance still outguns peak PCIe 3 speeds (3.9 GB/s for four lanes).

Dell 14 Plus 2-in-1 convertible review: AMD offers key advantage over Intel

The Dell 14 Plus 2-in-1 replaces the older Inspiron 14 2-in-1 series with both a fresh new name and the latest processors from AMD and Intel. You might want to choose carefully between the Intel and AMD configurations, however.
