SDSSDH-XXX or SDSSDH2-XXX

hi,

I want to know what is the difference between these two :

SDSSDH-XXX

SDSSDH2-XXX

thank you

SDSSDH = SanDisk Ultra SSD, Sandforce 1200 serise controller SATA Gen 2

SDSSDH2 or SDSSDHP = SanDisk Ultra+ SSD, Marvell controller, SATA Gen 3

thank you for that answer.
what is the difference between SDSSDHP and SDSSDH2 ?

No difference the SKU was wrongly printed on the label of the first batch. The current shipping SKU is SDSSDHP. 

thanks again.
