Mi recomendacion para realizar insert de gran cantidad de datos, es utilizar tablas externas. Estas son extremadamente rapidas.
Para esto
1 tenes que definir un archivo de texto con los datos. 
2 crear la tabla externa en firebird
3 realizar el insert a la tabla definitiba de los registros de tu interes

Not surprisiing at all, Stripe Set is the amount of Data a RAID moves for every read/write
so if you have 16 KB or 4KB you still move 64KB each time but with much less usable Payload per transfer
go for a Stripsetsize of 16 KB and a Pagesize of 16KB for best match
