Yes, still in use in some legacy stuffs.

There may be some inroads into the 10 bits per byte, but tcp is so old I 
doubt that synchronization portion took a hit.  Thats what it is, is 
keeping everything in synch. Even USB has that same data format. Sata 
for disks, being much newer, may have abandoned that, particularly for 
the disks whose native format is a 4096 byte sector. I've also found 
sata cabling is about 1000% flakier, requiring more frequent 
replacements.
