I’ve said it before and I’ll say it again, the increase in 2.5in ‘laptop’ hard drives is happening far too slowly. Toshiba may have joined the front runners this week by announcing a 200GB model, but flash memory is already posing a serious threat.
What makes this drive more interesting than the norm however is that is marks a breakthrough in data compression. Using perpendicular recording, the company has managed to squeeze 178.8 gigabits per square inch which is a sizeable increase on the previous record (which Tosh also held) of 133 gigabits over the same area. Consequently, while the 200GB capacity that this super squished data will debut at is not exactly stunning Toshiba says it means the ceiling for capacity increases at this form factor has been boosting significantly.
For the record, the 200GB drive itself is called the MK2035GSS, it spins at an unremarkable 4,200RPM, uses an SATA II interface, comes with an 8MB butter, provides an average seek time of 12ms and data transfer rate of 150MBps. Shipping will be as soon as early Q3 though no pricing has yet been released.
The capacity of the MK2035GSS may make it an industry equalling leader, but the real story here is the 30+ per cent increase in data compression. Personally, I won’t be happy until I’ve got at least a 300GB hard drive inside my laptop, but then that’s just me and I do like to carry around my high bit rate home movies… (*cough*).
