a raid card with bbu or cachevault will be a little bit faster because write requests are committed to raid card memory even before the SSD has finished writing the data.
mdadm raid 10 for 8x sata ssds should provide adequate performance, but if the raid card is not expensive it is worthwhile to get a bit more performance.
If possible, a pair of 8tb nvme in sw raid 1, or 4x 4tb nvme in sw raid 10, would be even better.
