($337 isn't $20-%50, but...): > http://www.acard.com/english/fb01-product.jsp?idno_no=382&prod_no=ANS-9010BA&type1_idno=5&ino=28 It's 32GiB, 20K iops (8KiB?), 14 minute CF dump, 4hr life, but only specs at 200MiB/s over sata2 (a few drives in jbod can match that sustained xfer rate). They make a dual port version at 16GiB and 200MiB/s per port (400MiB host striped). It's ddr2 ram is nearly obsolete and at $80/4GiB is almost 4x more than ddr3. Optional 64GiB CF card $85 (or use non-ecc ram emulate and a 32GiB CF card $40). Optional whatever 12vdc source you want to rig to it. So to fill it out you're looking at $295 dev + $640 ram ... $1100 stoked. And the ANS-9010B is 48GiB for $250. There's old Gigabyte gc-ramdisk i-ram, 4GiB, sata1, DDR1, battery ... ~$100 STEC ZeusRAM 8GiB, DDR3, SLC, SAS2, $2500-$3000 It's about as hot as the price. Bus based... You can get a PCI-e 4GiB, 60 second SLC dump, supercaps, from ddrdrive.com for $2000, and they might even let you write a FreeBSD driver for it. It's price, size and flexibility are not that hot, performance maybe 40K iops (4KiB), on par with the above. www.fusionio.com/products/iodrive-octal/ NAND... SLC 20GiB ish ... $150 MLC 60GiB ish ... $75 There's still room for a cheap DDR3+SATA3 unit. Or just fill out your motherboard slots and add a UPS :)
