| ===Speed===
| |
| | |
| 12 Gbps = 1.5 GB/s
| |
| | |
| 15 Gpbs = 1.875 GB/s

| 25 FPS 4096 x 2304 raw uncompressed 12 bit video daterate: 353.9 MB/s

| | |
| Prices evaluated March 2017:
| |
| | |
| If we filter out micro sd cards that have advertized write speed above 90MB/s the prices start at 0.50€/GB, pro brands are in the 0.60€/GB - 0.80€/GB ballpark.
| |
| | |
| 2.5" SSDs with advertized write speeds of 450+MB/s start at around 0.25€/GB - 0.30€/GB
| |
| | |
| 1.8" SSDs offer only very few models with 450+MB/s write speeds to choose from and prices are around 0.80€/GB - 1.90€/GB
| |
| | |
| M.2 SSDs connected over PCIe 3.0 x4 offering 1500+MB/s writespeed cost 0.40€/GB - 0.70€/GB and are the smallest and fastest option.

| '''Conclusion:'''
| |
| Using just 5 micro sd cards in a raid gives roughly the same combined speed as using one 2.5" SSD. In this configuration the SSD is less than half the price per GB as the micro SD raid.
| |
| | |
| When using 32 micro sd cards in the raid it would require roughly 7x 2.5" SSDs in a raid to match the same speed resulting in roughly 7 times the volume of the micro sd card raid

| ===Size===
| |
| | |
| 2.5" SSD: 70 x 100mm
| |
| | |
| 1.8" SSD: 54 x 78mm
| |
| | |
| One micro SD card: 11 x 15mm
| |
| | |
| 6x3 cards with small gap between cards and space to insert them plus an 23x23mm FPGA would require roughly the space of 64 x 104 mm (just slightly higher as the current 57.15mm that dual plugin modules occupy. Different layouts of cards are of course possible.

| ==Research & Notes==
| |
| * Manually selecting how many cards are used for increasing speed and how many are used for writing copies/backups would be very convenient.
