Hi All,

I was able to get a Dell branded PM1725b 6.4 TB off of Ebay. It came with firmware 1.0 which I was able to update to 1.2.1. I did notice a bump in benchmark numbers using CDM. Does anyone know if this is the latest version of the firmware?

Also, Samsung's spec sheet says that it can be "user-enabled firmware change to capacity-optimized" changing it from 3 DWPD to 1 DWPD changing the drive space to 7.68 TB. Can this be accomplished on the Dell firmware? I can't find Dell or Samsung's documentation on this.

Thanks!

Most enterprise SSD drives are indeed overprovisioned at the firmware level. Sadly I believe Dell never actually underprovisioned that particular model, purely because they gave customers the option to purchase different models right at the start.
