Yes. My Google-fu is not up to finding them but I happen to be familiar with this company's products and here is one.

One application of this kind of product is chip fabs because they are so sensitive to power disruptions.
Whether Toshiba/WD had this type of system and if so, why it didn't prevent loss of product was not mentioned in the linked article. I have heard that there is a glut in chips for SSDs so a reason to cut production can't be ruled out. However it seems like Toshiba/WD would pay the price for this outage while their competitors would reap the benefits (unless the competition agreed to somehow share the cost.)
