This category lists all Western Digital drives that are members of the WD Marvell family PebbleB. PebbleB improves the maximum platter capacity in a 15 mm 2.5" HDA from four in the previous Shrek LT, to five. Spyglass is a direct improvement of PebbleB; in fact, the very same R/N is present in Spyglass, as in PebbleB. PebbleB is the final CMR 2.5" family.
