What is the write endurance of LNM790X004T-RNNNU?
The published rating is 3000 TBW. It describes rated writes, not a predicted failure date. Warranty eligibility also depends on the manufacturer's terms.
What connection does LNM790X004T-RNNNU need?
LNM790X004T-RNNNU requires a M.2 2280 slot that supports PCIe/NVMe. Check supported PCIe generation, available lanes and heatsink clearance; a SATA-only M.2 slot is not sufficient.
How much usable space does LNM790X004T-RNNNU provide?
Its nominal capacity is 4000 GB, approximately 3725.3 GiB before formatting. The filesystem, reserved space and any RAID redundancy reduce usable capacity further.
What warranty is listed for LNM790X004T-RNNNU?
Manufacturer specification: 5 years, subject to manufacturer terms. A renewed, used, OEM or imported offer can have different coverage. Check the serial number and seller terms before buying.
