Hi there,
On my Marvell based Intel 510 120GB SSD (latest firmware PPG4) I've noticed unexpected behavior: Host Writes information (E1) would overflow at 4TB value. After reaching 4TB it starts counting from 0 (see attached pictures; before and after). It happened several times before, this time I paid attention and made sure it's really the issue and took screenshots. I didn't see this problem reported before.
Running on laptop machine, Intel i5 processor with HM55 chipset, SATA Gen2 enabled. No other issues with SSD observed.
