Battery life isn’t great, but this is par for the course with a laptop of this type. In our light-use test, the Satellite S70-B clung on for 5hrs 14mins. With the screen brightness cranked to maximum and the CPU working flat out, the Toshiba lasted only 1hr 14mins.The huge 17.3in, Full HD display ought to be a highlight, but this is where the Satellite S70-B begins to lose its lustre. Rather than the IPS panel technology found on most high-end laptops, Toshiba has saved money by opting for a low-quality TN panel. Colours look cold and unnatural even to the naked eye, and our X-Rite i1Display Pro colorimeter gave the display a damning report.The panel’s high 362cd/m[sup]2[/sup] brightness is the only plus point. Contrast is low, at 492:1, and the panel covers only 86% of the sRGB colour gamut, so colours aren’t as rich and saturated as they should be. Colour accuracy is woeful – everything from games to photographs is dogged with an unnatural tint – and vertical viewing angles are infuriatingly narrow.

HP has revamped its line-up of mobile and desktop workstations, adding support for Thunderbolt 2 and PCI Express-based SSDs and ushering in Intel’s Haswell-EP Xeon CPUs.Thunderbolt 2 is now available across all of HP’s mobile and desktop workstations, and the Z Turbo Drive – HP’s catchy moniker for a blisteringly quick PCI-Express M.2 SSD – comes as an optional upgrade.HP’s family of desktop workstations also now support Intel’s Xeon E5-2600 v3 range of processors. These CPUs are based on Intel’s new Haswell-EP architecture, which spans a range of dual-, quad- and eight-core parts. At the top end of the desktop family, HP’s Z840 workstation is ready to accomodate a pair of the new chips – the air-cooled chassis is rated to cope with CPUs with a maximum TDP of 160W.

So how does it perform? We used the Black[sup]2[/sup] to upgrade an Ivy Bridge Core i7-powered Dell laptop, replacing the standard 5,400rpm 1TB HDD. We found Windows 7’s boot speed halved from 40 seconds to a speedy 21 seconds, and our benchmarks also saw a performance boost: the Responsiveness element of the benchmarks, which opens and closes Explorer windows and a series of apps, showed an 11% improvement. We then connected the Black[sup]2[/sup] to our standard test rig, and ran AS SSD on the SSD partition to determine absolute read and write performance. In this test, the Black[sup]2[/sup] returned sequential read and write speeds of 359MB/sec and 140MB/sec, and 4K read and write speeds of 25MB/sec and 46MB/sec respectively. This isn’t anywhere near as high as our A-List SSD, the Samsung 840 Pro, but there’s plenty of speed here to give an older laptop a big lift.

Finally, to measure the performance impact of accessing both partitions simultaneously, we ran AS SSD’s sequential test on both the SSD and the mechanical disk at the same time. Read and write speeds on the SSD to dropped to 95MB/sec and 77MB/sec respectively, although the system remained perfectly responsive.The idea of squeezing an SSD and HDD together into a single case is attractive, but it only makes sense if the price is significantly cheaper than a standalone SSD. Fortunately, the dual drive scores well on this front: its £230 price works out to 22p per unformatted gigabyte. The Samsung 840 Pro costs more than three times this, and even the cheaper version – the 840 Evo – costs more than double.The Black[sup]2[/sup] dual drive may not be the fastest SSD around, but if you’re after a performance boost for your single-bay laptop, it’s the only drive we’ve seen that offers both speed and capacity, making it a highly appealing upgrade.

Perhaps it was due to manufacturing efficiencies – you can cut more squares from a sheet of LCD than round ones, after all – but a square watch, particularly one as bland and boring as the LG G Watch, just doesn’t look as good as a round one, as the Moto 360 proves. It isn’t only the shape, though. Everything about the design of the Moto 360 screams sophistication and high-end charm. The edge of the glass front is sharply bevelled, and that bevel slices backwards towards the watch’s steel body, where it plummets abruptly into the watch’s vertical sides. There’s a good-sized button on the side for waking the watch up and turning it off, and the thick leather strap feels beautifully well made.The Moto 360 looks great whether you buy the silver model, which comes with a grey strap, or the black one, which comes with a black strap. It’s also comfortable to wear, which isn’t something we can say for all the smartwatches we’ve tried. And there’s a good selection of alternative watch faces preinstalled; you get six as standard, and there’s already an extensive selection to choose from on Google Play.

Flip it over and you’ll see seven small dots on the back – evidence of the fact that the Moto 360 is equipped with an optical heart-rate monitor – and in another triumph of clean design over clutter, no exposed charging contacts. The Motorola Moto 360 employs Qi wireless induction charging, and a charging cradle comes supplied in the box. Plug that charger into the supplied mains USB adapter, or a spare socket on your PC or laptop, and all you need to do to charge the Moto 360 is drop it into place. In a neat touch, the watch face rotates sideways into an alarm-clock mode whenever you do this, indicating the amount of battery charge remaining with a blue line that extends gradually around the circumference of the watch face.

Like other smartwatches we’ve tested, the Moto 360 is tough, too: an IP67 rating means it will survive being worn in the shower or even the swimming pool, although we wouldn’t advise diving too deep as it’s only rated for immersion in 1m of water for up to 30 minutes. Up front, the watch face is made from scratch- and shatter-resistant Gorilla Glass 3.The round design certainly sets the Moto 360 apart from the Android Wear competition. However, since it’s running Android Wear, there’s little difference in the way it works. You navigate around the watch’s interface by swiping and scrolling, notifications pop up on Google Now style cards, and you can use voice recognition to set alarms, calendar entries and kick off navigation, among other things.

Android Wear was designed from the start to support round watch faces, so the Moto 360’s round design works perfectly, and the 1.56in-diameter, 320 x 290-resolution IPS display beneath the glass is bright enough for comfortable viewing in most conditions (we measured it at 502cd/m2 with a mostly white watch face). It has noticeably more get up and go than the G Watch at maximum brightness (404cd/m2), and since it’s the first Android Wear device to have a light sensor, it will adapt to its surroundings as well.By default, the Moto 360’s display remains off most of the time, but the screen will activate whenever you lift your arm and twist your wrist. It’s a gesture that works 99% of the time, and much more reliably than on the LG G Watch, so there’s no need to leave on the screen permanently.http://www.dearbattery.co.uk

As with many other wearables (such as the Samsung Gear Live), the Moto 360’s heart-rate monitor can only take a one-off measurement and can’t continuously monitor your pulse, rendering it useless as a training tool. It’s affected by movement, too, so you have to stay still while it does its thing. On the plus side, the measurements appear to be reasonably accurate, and we do like the Motorola Heart Activity app that goes with it. This works in a similar manner to Android Wear’s standard pedometer app, displaying your heart rate over the past week, and keeps its beady eye on things by measuring your pulse rate periodically when it spots you’re up to something more active than sitting at your desk.

It will have difficulty monitoring any kind of activity if you happen not to be wearing the watch at the time, though, and poor battery life means you’ll likely spend a fair amount of time with the Moto 360 off your wrist. With the screen in default mode and set to switch off periodically, the Moto 360 never lasted longer than a day and a half for us.It’s an improvement on the performance US customers experienced before a recent update, but still not brilliant. We also ran our new smartwatch battery test on the Moto 360: we connected it to a test Gmail account set up with reminders every five minutes, set the screen to its minimum timeout setting and full brightness. After a few hours of testing we were able to project a full runtime of 27 hours. The LG G Watch gained 50 hours in this test, and the Samsung Gear Live 36 hours.
