UBOs are limited to 64KB on most hardware, while SSBOs support gigabytes of read/write structured data directly inside compute shaders.

SSBOs support atomic operations (atomicAdd, atomicExchange), making them perfect for GPU particle simulations and indirect draw buffers.

Using std430 memory layout in SSBOs avoids the strict 16-byte alignment rules of std140 in UBOs.
