The storage industry continues to move at a rapid pace as Japanese manufacturer Toshiba has today announced its largest-ever 2.5in hard drives with the introduction of its MK7559GSXP and MKxx59GSM series.

Starting off the range is the new 750GB MK7559GSXP, pictured above. Featuring just two platters, the compact 2.5in drive measures 9.5mm thick and provides an areal density of 541.4G bit/inĀ².

Operating at 5,400rpm, the drive features an 8MB buffer and provides an average seek time of 12ms. Scheduled to ship in the third quarter of 2010, the drive will arrive as the higher-capacity successor to the 640GB MK6465GSX introduced last September.

Prior to that, Toshiba will introduce a pair of thicker 2.5in drives in the second quarter as part of its MKxx59GSM series. Available in 750GB and 1TB capacities, the drive will follow in the footsteps of Western Digital, using three platters to achieve the required density at the expense of drive dimensions. Measuring 12.5mm thick, both drives won't be compatible with the majority of today's notebooks, but will instead be aimed at upcoming gaming notebooks or external storage solutions.

Both 12.5mm-thick drives will again feature speeds of 5,400rpm - making the 1TB offering slightly quicker than the 5,200rpm Western Digital alternative - and come equipped with an 8MB buffer and a 12ms average seek time.

Awesome. And about time too.

I have this preconception, however, that 2.5 inch drives are more prone to failure than 3.5 inch drives. I don't know where I got this from: perhaps the number of drives in caddies I have had go wrong, but that, in itself, is probably a side effect of carting them about all the time, and the (relatively) rough treatment they get.

Are there any stats on this? Logically, I'd imagine failure rate should probably be about equal.
How do they fit 2 platters into those? :o
They have three platters in the larger sizes, not two. They are also thicker at 12.5mm.

It probably has more to do with 2.5" drives being in caddies/laptops etc so getting moved around/dropped etc like you say.
These drives r too big to fit into most laptops mayb apart from a dell xps or an alienware! useless for the rest of us
