The Register's sources claim the first 1TB 2.5" notebook HDDs from WD will arrive by early 2010, if not the end of 2009, while 750GB models are expected by mid-2009. The site also suggests Seagate may be even faster with its 750GB and 1TB notebook hard drives.
Our sources say WD and Fujitsu will have 750GB 2.5-inch drives by mid-2009 and 1 terabyte units by early 2010, if not the end of 2009. WD is building quite a track record of pipping Seagate by introducing notebook drives at progressively higher capacity points first, doing this with 250GB, 320GB and now 500GB models. This may not continue as Seagate has been catching up and will strive to match and exceed WD.
Seagate may well have its 750GB and 1TB notebook drives available before WD.
