What is the write endurance of LNM790X001T-RNNNU?
The published rating is 1000 TBW. It describes rated writes, not a predicted failure date. Warranty eligibility also depends on the manufacturer's terms.
What connection does LNM790X001T-RNNNU need?
LNM790X001T-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 LNM790X001T-RNNNU provide?
Its nominal capacity is 1000 GB, approximately 931.3 GiB before formatting. The filesystem, reserved space and any RAID redundancy reduce usable capacity further.
What warranty is listed for LNM790X001T-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.
