Modern consumer SSDs still benefit from TRIM, but are mostly able to keep up with GC just fine without it when subjected to typical consumer IO workloads, which are full of idle time for the drive to catch up. But if you fill an SSD to the brim, it'll slow down, and the cheapest SSDs will slow down a lot.

There are no hardware RAID solutions for NVMe, though there are now several hardware platforms supporting software RAID for NVMe devices in their motherboard firmware so you can boot from a NVMe RAID array. As with any other RAID solution, translating trim/unmap/deallocate commands takes a bit of effort, and less mature NVMe RAID solutions don't necessarily bother.
