Whats the diff. between a PX-708A/T3K and a PX-708A/T3?

Ok silly question Im sure but what is the difference between the PX-708A/T3K and the PX-708A/T3 ? Ive seen both drives listed on sites, few £’s diff. in price but spec seems the same.

Thx in advance.

Not absolutely sure but my guess would be the K is for black hardware rather than beige.

No, a ‘K’ means Bulk version. A ‘B’ means Black version
