Security researcher on HBF hype: matching HBM's 4.8TB/s needs ~4900 NAND planes and a tricky programming model

Security researcher lauriewired cautions against HBF (High-Bandwidth Flash) marketing hype. To match an H200's 4.8TB/s bandwidth, napkin math says you'd need roughly 4900 NAND planes — achievable only through extreme parallelism. She points to FlashAccel and FLINT as the key reading, stresses the programming model is genuinely tricky, and argues physical data arrangement will matter enormously in this space going forward.
