Overview

• The PCIe 4.0, DRAM-less SN5100 pairs SanDisk’s controller with Kioxia BiCS8 QLC in a single‑sided M.2 2280 design offered at 500GB, 1TB, 2TB and 4TB.
• Official specs peak at up to 7,100 MB/s reads and 6,700 MB/s writes with up to 1,000,000 read and 1,300,000 write IOPS on the 1TB and 2TB models.
• Vendor comparisons cite up to roughly 29% faster sequential reads, 34% faster sequential writes, 37% higher random reads and 44% higher random writes versus the SN5000.
• Endurance ratings are unchanged at 300/600/900/1,200 TBW by capacity, and the drive carries a five‑year limited warranty.
• MSRPs are set at $54.99 (500GB), $79.99 (1TB), $149.99 (2TB) and $299.99 (4TB), representing notable increases over the SN5000; included extras feature Acronis True Image and Host Memory Buffer support with a hybrid SLC cache.
