16 Gen5 NVMe drives in RAID 0 hit 208GB/s, matching 4-channel DDR5
carrigmat · x · 2026-08-27
carrigmat addresses the two biggest objections to running frontier LLMs from NVMe instead of GPU/RAM:
- SSD wear: modern SSDs have virtually infinite read lifetimes; weights are copied once and then it's all reads.
- Bandwidth: one Gen5 NVMe gives 13GB/s; 16 in RAID 0 reach 208GB/s, equivalent to 4-channel DDR5.
