Top Secret: 20+TB SSD is nothing

Utah has much bigger, and you're in it. Anyone do a raw component and assembly cost workup on 25 / 50 / 100 TB class units? Jim?

Sorry about the delay. I've been out of the SSD business for 28 years. when in, the only thing we had was DRAMs, which at the time were 4Meg chips, and 9 of them fit on a 9-chip 30-pin SIMM card. The largest SemiDisk we made held 54 megabytes of these (14 SIMMs, back when hard drives typically held 200 megabytes. Micro SD cards are truly amazing things, the size of your pinky-fingernail.. When I built my 64 kilobyte main memory "Bellyache I" Z-80 computer (Parody name from "Illiac IV", a massively parallel computer in the late 1960's, https://en.wikipedia.org/wiki/ILLIAC_IV ) I had 8" floppy disks which held 240 kilobyes on a single-sided, single-density floppy. I first paid $5 for a Maxell. The capacity seemed huge! Nearly would hold a paperback book size of data. It would be possible to imagine a small box that held as many micro-SD's as could be crammed into the volume. The lowest-cost-per-gigabyte units are probably about 256 gigabyte micro-sd. $35 each, maybe, .https://www.amazon.com/SanDisk-256GB-microSDXC-Memory-Adapter/dp/B0758NHWS8/ref=sr_1_3?keywords=micro+sd+card+256&qid=1585687886&sr=8-3 (Warning! Most 'off brand' micro-SD devices are FAKE) One hundred of those things packed into a 3 1/2 inch hard disk size, maybe? Of 25 terabytes? Add another $200 for the controller CPU, hardware, etc. Something like that should be available already. But I haven't looked. Jim Bell

256GB generic (probably OEM Adata's) USB 3.1 $28, work fine. 256GB generic SD 10uhs-1 is $33. 25TiB of either would be around $3100. 1TB of SATA SSD is $1000, 25TiB around $2800. Retail flash is at least 5x more $ than platters. That's all retail so a production run would be quite cheaper once you get a PCB run, some bulk trays of flash and junk, and an easybake oven to flow solder in house, seems pretty clear you could make a killing bidding the likes of whoever they were selling 25TB to at $40k. The chip makers will quote you trays without much fuss. Or try OEM the whole thing. Marketing a either 10x size, or speed, or both... will profit.

Capacity fill test. Flash and hard drives do compression now, so to speed test you can't use /dev/zero, use /dev/urandom instead.
Something like that should be available already.
Haven't seen anything. Users with basic 10Mbps internet would take 255 days to fill one.
