Newegg is running some specials: a 64G Kingston SSD for $140, a 256G (yikes!) Crucial SSD for $660, and a Sans Digital port multiplier for $110. The SSDs are good for using swapcache(8), though 256G is probably overkill. Doesn’t make me want it less, though…
The port multiplier’s SiI3726 chipset might be supported, or potentially supported, by the sili(4) driver. Someone have $110 to spare to try this out?
