This press release is for a PCI SSD but they are the exact same memory chips that are in a 2.5 SATA SSD. 10 Petabytes of writes is a HUGE amount of data and the average user will never come anywhere near this (Even in a server environment 10PB of writes is extremely rare).
The P420m is rated for 10PB of total drive writes (~4 drive fills per day for 5 years)
