A 3.84TB enterprise SATA SSD rated around 1.3 drive writes per day with power loss protection. SATA caps throughput near 550MB/s, which sounds slow next to NVMe until you remember that six of them in a ZFS pool saturate 10GbE anyway. The cheapest route to bulk flash in a server with no spare NVMe slots.
Across 33 listings tracked in the last three days, the median total cost in USD including shipping is $525, and the lowest is $400. RackSniper flags a listing once it falls at or below 70 percent of the trailing 30 day median, which for this product means roughly $368 or less. Condition and configuration vary widely on used enterprise hardware, so treat the median as a reference point rather than a target.
