Description
Hikvision is better known for surveillance hardware, and the G4000 reflects that background: its rated endurance of 3600 TBW is three times the Samsung 990 PRO at the same capacity, which is the figure that matters when a drive is written to continuously rather than in bursts.
Key specifications
- Sequential 7450 MB/s read, 6750 MB/s write
- Random 860K / 690K IOPS (4K)
- 3600 TBW endurance, 5-year limited warranty
- 3D TLC, DRAM cache, graphene heatspreader on the label side
Where it fits
NVR and video-capture storage, CCTV workstations, and any always-writing role that would burn through a consumer drive's write budget. Also a straightforward PS5 expansion drive.
Trade notes
Retail-boxed. A separate SKU ships with a full aluminium heatsink; the version listed here carries the thin graphene layer only. Brand recognition is lower than Samsung and Kingston — lead with the endurance figure, not the badge.
