Samsung 840 Pro 512 GB review: ample SSD with 100k IOPS read performance


Samsung has worked hard from a nearly standing start to gain consumer mindshare as a premium supplier of SSDs for after-market upgrades. With Toshiba, the Korean giant is one of only two brands that can control the whole design and manufacture of the flash memory, the controller and the controller firmware. See all Storage reviews.

In 2012 Samsung split its range into two: the 840 and 840 Pro Series. The latter tested here is a development of the previous 830 Series, while the standard 840 perhaps marks the larger departure from the beaten path: the world's first SSD using three-layer cell flash in order to reduce costs. See Group test: what's the best SSD (solid-state drive)?

Samsung keeps with its DDR2 memory cache, perhaps for power economy, and ups this to 512 MB. In control is a proprietary three-core ARM processor, running Samsung's own firmware. Flash itself is also from Samsung's fabs of course, 21nm toggle NAND, reduced from its previous 27nm process. Take a look at the Corsair Neutron GTX 240GB SSD review too.

Samsung backs this MLC-based drive with a 5-year warranty, although platform support is resolutely limited to Windows. It's possible to adjust over-provisioning using the SSD Magician for Windows software, as well as run rudimentary benchmark tests.

We did experience an unusual issue using this drive in our MacBook Pro workhouse became inoperable with this drive fitted, due to Bluetooth inteference. Two samples supplied to check if the first was rogue proved defective too, although this was later traced to Samsung issuing broken customer-returned RMA drives as review samples.

100,000 IOPS was the goal, and that's what Samsung has achieved given the right metric. AS SSD indicated lower but still impressive figures of 86.7k and 81.1k for 4kB read and write IOPS. The same benchmark tool also indicated the second-best nominal score here, with 1094 points not far behind Plextor's 1124. We tried the SSD Magician tool, which reported 98.4k read IOPS.

But halving the number of threads to 32 in CDM, we found the best peak IOPS result of the group, with a stunning 103.8k read IOPS. Write IOPS weren't so very far behind either, at 93.5k.

CDM clearly showed the Samsung's indifference to data type. Not only did the random data test match that of compressible data, it actually exceeded it. The best results here were 516 MB/s reads and 496 MB/s writes, while ATTO returned the highest sequential read results of 562 MB/s.

Synology Mesh Router MR2200ac Review

You probably know Synology for making NAS drives but the firm has also turned its hand to mesh networks. Here we review the MR2200ac.
Should I Buy The Synology Mesh Router MR2200ac?
Synology could do a little more to explain the many features of the MR2200ac for first-time users, but the strong performance of this mesh system, and the fine-control provided by its web browser interface make it a good option for business users or home users who have a little more experience of networking technology.

Huawei P Smart 2019 Review

Huawei has updated its budget Android phone for 2019. It’s faster and better than before, but should you buy it? Read our review to find out.
Should I Buy The Huawei P Smart 2019?
The P Smart 2019 is a great upgrade from the 2018 model with a bigger screen and better performance. However, as with the original P Smart, Honor's version is better value.

Oppo RX17 Pro Review

Though similar to the OnePlus 6T the Oppo RX17 Pro is very different thanks to the software. Here’s our full review
Should I Buy The Oppo RX17 Pro?
The RX17 Pro is a great looking phone with good performance and a lush display. But with a Snapdragon 710 rather than the better 845 it’s just impossible not to compare it to the OnePlus 6T which looks the same, has better software for the western market and, importantly, costs less.
If you like the look of Oppo’s interface though then there’s a lot to like. The two colour options are premium as is the build quality and the cameras are above average if not great.

Moto Z4 Play Release Date, Price & Spec Rumours

We investigate rumours surrounding the Moto Z4 Play, which could be announced in June 2019 with an in-display fingerprint sensor.
Announced in June 2018, the Moto Z3 Play was never joined in the UK by the standard Moto Z3. It's possible that for the Z4 series we will again see only the Play model go on sale here, with the Moto Z4 Play expected to be announced in the UK in mid-2019.

Nokia 9 Release Date, Price & Spec Rumours

We've waited two years for the Nokia 9, and at the end of this month the company could finally put us out of our misery. Here's what we know about the Nokia 9 PureView, which could feature a penta-lens rear camera.
Nokia made its comeback to the Android market in January 2017 with the Nokia 6, and we've been waiting two years now for its long-rumoured flagship Nokia 9 to arrive. At MWC 2018 we thought that time was here, and then we got the the Nokia 8 Sirocco. But now the wait could really, really be over, as the Nokia 9 is tipped to land before the end of January 2019.
