Black SN850X 1TB
1TB · PCIe 4.0 x4 · 7300 MB/s
$164.99
Overview
Samsung's Gen4 flagship, saturating PCIe 4.0 x4 at 7450/6900 MB/s without inflating the numbers. The DRAM cache keeps random I/O steady once the SLC burst runs out, which is where cheaper drives stumble. 1TB and 600 TBW make it a strong boot drive, though the 2TB is the better value if you need the room.

- Andre F.Jul 27, 2025Cool and consistent
Never seen it throttle under my board heatsink. Saturates Gen4 reads. Samsung Magician makes health monitoring easy.
- Lydia N.Mar 15, 2025Great, but 1TB fills fast
No complaints on speed at all. Just know that with modern game sizes 1TB goes quick, so size up if it is your only disk.
- Nour H.Dec 28, 2024Solid but the 2TB is better value
Per-gig the 2TB makes more sense, but if you only need 1TB this is a top-tier drive. Zero issues in six months.
- Bruno K.Sep 19, 2024Perfect OS drive
1TB for the OS and core apps, everything snappy. Full DRAM so it does not fall apart under sustained load like DRAM-less drives.
