V7000 V5000 stripe width Tier1 Flash

The lsarrayrecommendation on a V5000 and V7000 gives me the advise to use a Stripe Width (12) when creating a DRAID-6 arrays with 300GB drives.

When I use a larger Stripe width (16), I will get more useable capacity (in this case with 18xSSD drives: 4TB instead of 3.8TB). It will be much more using the larger SSD’s

When using Tier1 Flash is there a performance impact when using this larger stripe width?
Or are there other considerations?

Thanks
