Toshiba Announces Latest Series Of 1.8in HDDs

Making things more power efficient and with higher capacities was not enough for Toshiba, as they have announced the world's first HDD which uses the low insertion force (LIF) SATA connectors to reduce the space they take up.

While SSDs may be the future, until the price of the technology comes down we will be being HDDs in our gadgets for some time to come. Toshiba has therefore announced its largest capacity 1.8in single-platter Hard Disk Drives which are aimed at the portable market of phones, tablets and PMPs. Toshiba did however release the MKxx33GSG series in 2009 which had a top capacity of 250GB but these were dual-platter and 8mm in height compared to these single platter devices which are only 5mm in height.

Toshiba has opted to equip the three new MKxx39GSL HDD series with LIF SATA connectors, which gains a 10 percent footprint reduction over similar devices employing microSATA. The MK2239GSL, MK2039GSL, MK1639GSL have capacities of 220GB, 200GB and 160GB respectively and are all designed to work with portable devices such as the ever growing tablet market.

While Toshiba has increased the capacity and reduced the footprint of its new HDD series, it claims that it has also made major power efficiency changes. The MK2239GSL, for example, uses 30 percent less power than previous models according to Toshiba. The lower power consumption will increase battery life, which is essential for mobile multimedia devices such as notebooks or tablets which can require a lot of battery power when viewing movies.

Each HDD also has a buffer memory of 16MB and interface transfer rate of 1.5 Gb/sec. It is claimed the new series will have a vibration robustness superior to the 2.5in form factor. The MKxx39GSL series weigh just 48g and externally measures just 54 x 71 x 5mm. The HDDs will be available in February and though Toshiba are reticent about issuing pricing at the moment though we will bring you an update as soon as we hear.

I'm probably just being stupid but my current laptop has a 250Gb 1.8Inch hard drive @ 5400rpm. So how is this bigger?

Or is this a totally different connection that is smaller?

The laptop is a thinkpad t410s if that helps

@Chris Hamer: I think this is a single platter 5mm drive, rather than a dual platter 8mm drive.

Oh that makes sense :) Hope they make a 500GB 8mm drive :p

@Chris Hamer

I would have thought it has a 2.5" drive, not a 1.8"? There are very few laptops that do.

Here's that 250GB 1.8" Drive. David Gilbert should eat his socks for that headline :)

@MGDdrinker First things first. I received the press release from Toshiba which opened with the line: "Please find below the latest news from Toshiba, announcing the launch of its largest 1.8-inch Hard Disk Drive to date." From there on I, for better or worse, took Toshiba at its word.

Secondly while the HDD you point to has a capacity of 250GB, it is I believe dual platter rather than single platter like the MKxx39GSL series announced here. However it matters not a jot whether it is single or dual-platter as they are all HDDs and obviously the MK2533GSG has a larger capacity.

I have requested clarification from Toshiba and while we wait on that, I will keep my socks on standby.

@MGDdrinker Ok so I've just spoken to Toshiba and they confirm that the MK2533GSG was dual-platter and 8mm in height compared to the single-platter 5mm-high MKxx39GSL series. Now obviously the headline is misleading and is in the process of being changed but whether it merits me eating my socks is open to discussion I think!
