Apple is considering a major investment that'd give it a sizable stake in Toshiba's storage business. Bloomberg says it could contribute $3 billion to Bain Capital's bid to take over the business. Just last week, Apple was reportedly playing a role in three separate bids.

The other current bids are from Foxconn and KKR (with the support of Western Digital).

Since $3 billion appears to be the most Apple has considered investing, it appears heavily committed to getting the Bain deal to work. Bain also has support from Dell and Seagate.
