A comment on SanDisk 1TB MicroSD Card Review.

I imagine at times like this a small USB-3.2 device which is a RAID-6 array of 20 or 30 microSD cards, probably a small FPGA to provide the 30 port SDIO device that can do 100MB/s per channel, a two gigabyte static ram with battery backup (coin cell) for holding open stripe state, and a SCSI or SAS export point for reporting out as a drive. Device is probably the size of a deck of cards, maybe smaller, consume or feed data at a GB/s all day.

That would be pretty freaking amazing.

Have you seen the T series portable ssd’s by Samsung. Nowadays multiple companies make portable ssds that use the same nand in their internal ssds but in a smaller custom form factor. They’re exactly like what you described, about the size of a deck of cards and much much more reliable and cheaper than micro as cards.

There are devices kinda like this, but they are hacky and unreliable.

It would offer good throughput but there is no way to hide the latency.

Could you elaborate on that thought? My experience is that it is possible to create a storage element with arbitrary throughput and latency (within a fairly wide design space) by composing storage elements.

You can create a storage element with arbitrarily _large_ latency...

You mean, you want a homebuilt spit-and-bailing-wire Beowulf cluster of these things?
