Kingston 256GB MicroSD XC card review
This expensive Class 10 card is Tardis-like but not the fastest we’ve tested
- Whopping 256GB capacity
- Not the fastest
- Only comes with SD card adapter
A gargantuan capacity for such a tiny device. But dropping down to 200GB slashes the cost and improves performance and value.
Price$ 349.00 (AUD)
We were amazed when Lexar provided us with a super-fast 200GB, corn-flake-sized MicroSD card back in June but now here’s Kingston with 256GB!
Like Lexar this is rated as a Class 10 and UHS-1 device which means it’s certified to record at a minimum of 10MB/s. These class ratings are designed by the SD Association to inform (primarily) videographers of the ability of SD-based media to record (extremely) high resolution footage. Class 10 is currently the highest rating. Kingston also claims a read speed of 45MB/s.
We threw a barrage of tests at it (using Lexar’s MicroSD USB 3 card reader) and here’s what we found...
We ran the CrystalDiskMark benchmark several times in order to get consistent results (which were not always forthcoming in these tests.
In the important 4K sequential test the Kingston consistently scored over 10MB/s and topped out at 12.16MB/s write speed. The Lexar score on the right is lower in this test, but in other runs was much higher. In the straight data transfer write speed test however, the Lexar was always consistently ahead by some way with Kingston never getting higher than 13.13MB/s while Lexar pushed up to 39.87MB/s. But these scores reflect a wild ride. We’d say the Lexar was faster at writing here though.
When transferring our 1.62GB of 1000 AMD driver files it averaged 8MB/s – which might be under 10MB/s but many of those files are tiny so consistent writing speed is impossible. It read them back at 38.5MB/s. However, the Lexar was faster at writing with its 13.2MB/s write speed but similar with a 34.5MB/s read speed.
We also moved our new 30GB test file. The Kingston card scored 20MB/s write and 86MB/s read speeds. Conversely, the Lexar scored 30MB/s write and 75MB/s read.
So in terms of performance, both cards are very fast but the Lexar was consistently faster at writing by more than 50 per cent. Tests were pretty wayward though: we wouldn’t be surprised if heat issues played a part here as the tiny cards got pretty warm when testing. Both should be more than adequate for any current video camera or phone storage applications though.
At $349 RRP Kingston’s card is tremendously expensive. It will cost less when availability increases but it’s unlikely to be near the cost of the $143 Lexar for some time. Furthermore, the Lexar comes with a useful USB 3 card reader while the Kingston only comes with an SD card adapter. So the Lexar destroys it for value and has noticeably-faster write speeds. However, at this end of the market price will be irrelevant for many users and having a 256GB capacity in small, fast card will make it most attractive.

The HP OfficeJet 250 Mobile Printer is a great device that fits perfectly into my fast paced and mobile lifestyle. My first impression of the printer itself was how incredibly compact and sleek the device was.
Wireless printing from my iPhone was also a handy feature, the whole experience was quick and seamless with no setup requirements - accessed through the default iOS printing menu options.
A smarter way to print for busy small business owners, combining speedy printing with scanning and copying, making it easier to produce high quality documents and images at a touch of a button.
I've had a multifunction printer in the office going on 10 years now. It was a neat bit of kit back in the day -- print, copy, scan, fax -- when printing over WiFi felt a bit like magic. It’s seen better days though and an upgrade’s well overdue. This HP OfficeJet Pro 8730 looks like it ticks all the same boxes: print, copy, scan, and fax. (Really? Does anyone fax anything any more? I guess it's good to know the facility’s there, just in case.) Printing over WiFi is more-or- less standard these days.
As a freelance writer who is always on the go, I like my technology to be both efficient and effective so I can do my job well. The HP OfficeJet Pro 8730 Inkjet Printer ticks all the boxes in terms of form factor, performance and user interface.
I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.
