ahead of the curve
Not that my array has(or will get) FAST(v2) like technology, but I guess I'm ahead of the curve in that using 100% sata in my enterprise storage system to provide both good performance and high capacity when all disks are striped together. It doesn't scale low all that well but at a certain point(I'd say for 3PAR architecture at least 100 disks) it works well. Our system has 200 disks, going to 300 next year. Previous array had more than 500 disks, half of them being 10k RPM, new system is faster overall and has more net usable storage because of the added performance.
