Toshiba has some SSHD's too, but I think they're also 5400rpm. You're probably SOL unless you want an old model like the Momentus XT, and given the areal density improvements in newer drives, a newer 5400rpm drive is almost certainly faster than an older 7200rpm drive with lower areal density.
Toshiba product page for Toshiba's SSHD's:
SR benchmarks of an old (circa 2013) Seagate Momentus Thin vs. the even older Momentus XT... note in actual application traces, the Momentus Thin is faster... the newest one is the Seagate FireCuda, but I'm not seeing any reviews yet...
The current (circa 2015) Seagate Laptop SSHD 1TB smokes the 750GB one in desktop benchmarks, but I think it's now technically one generation behind the Seagate FireCuda 2.5" line.
