10^18 bytes in petabytes = 888.17 petabytes

or basically a million terabytes if you round up.

basically 3 million 1TB hard drives in raid 5 (1M x 3). you can probably fit a 500 1TB 2.5" drives into a single rack if you really try, and 2,000 racks can fit easily into warehouse-sized facility. (grid of 100 x 20 racks)
