One page, two clear sections each led by its chart: price-per-TB over time
(the crunch), then how often drives go on sale. Adds sale-frequency-trend.png
(branded chart matching the $/TB one).
Per-model and weekly computed figures: how often each current 8TB+ drive
goes on sale (best price 5%+ below its own rolling-median baseline) and how
deep. NAS lines discount several times more often than enterprise; similar
depth. Computed values only, compiled from Amazon price history.
Computed monthly medians (Jul 2024 onward) plus a chart and a write-up
(the trend, method, buyer takeaway, and usage note). Aggregate only - no
underlying per-drive price observations.
