I got 4TB of TLC for $230 (Silicon Power UD90). It even has SLC caching (can use parts of the flash in SLC mode for short periods of time).

True, I was looking at the prices for higher end drives with on-board DRAM, but DRAM-less drives like that UD90 are also fine in the age of NVMe. Going DRAM-less was a significant compromise on SATA SSDs, but NVMe allows the drive to borrow a small chunk of system RAM over PCIe DMA, and in practice that works well enough.

(Caveat: that DMA trick doesn't work if you put the drive in a USB enclosure, so if that's your use-case you should ideally still look for a drive with its own DRAM)
