Notebook Battery Life
For more information on how we test notebook battery life, click here.
We expected Marvell's controller (built on a 28nm process) to fare better in our notebook battery life power test. Not only do Samsung's models deliver better battery life, but even the M6e Black Edition outperforms the Predator here.
We believe the HyperX Predator is working harder in the background than its competition to maintain high performance. This can be seen with the drive connected to power-monitoring hardware. Let's say you transfer a 500MB file to the Predator. It uses a lot of power once the transfer is finished, illustrating the additional background activity. Some products shuffle data at a slower rate to save power, while others are aggressive.
Background activity is also why we don't measure SSD power in four-corner tasks. A drive may sip power in these specific benchmarks, but then use more while it moves information around. This can materialize as a spike while shuffling data quickly or increased consumption over time as data is moved around. Both scenarios are represented incorrectly when looking at power use for short periods of time. The notebook battery life tests allow us to measure power over a much longer duration and in a meaningful way.
The PCIe-based M.2 SSDs all deliver nearly identical performance in a power-restricted state. SATA products often demonstrate wider variation between models.
After first disconnecting the old device though, because otherwise Windows won't boot - it assumes the presence of another Win inst with the same ID is suspicious. I'm surprised this isn't mentioned more often when free cloning sw is highlighted in an SSD's accessory package.
Re pricing, the tiny difference between the M.2 and PCIe versions shows just how much one gets ripped off when buying other types of HBA, given Kingston is happy for the gap to be just $12, though I don't get why the gap is larger for the 480GB when it's the same item that's excluded for the M.2 version.
Personally, depsite the performance of this device, the small warranty would put me off.
Yes, that and one good standard SATA3 for comparison, preferably the 850 Pro 512GB.
Btw, is it just me for whom all the thumbnail images in the results galleries are blank?
it would be nice to have comparison with regular SSD. Is it better than that. I can't tell from this review :(
At the time I didn't have the Intel SSD 750 400GB. I do now and the review should come out very soon.
I'm just about finished with an article that puts the SM951-NVMe and SM951 AHCI against an 850 Pro.
Even without the data to compare in this review we know that the 850 Pro (512GB and 1TB) does roughly 550 MB/s sequential read, a bit over 500 MB/s sequential write, 98K random read IOPS and roughly 90K write IOPS in my testing.
If you compare equal capacity sizes, nearly every product in this review performs better than 850 Pro.
I'm up against a hard limit of the number of products I can put in the charts without needing a magnifying glass to look at the data. I'll see about coming up with something a little better for the Best of SSD Monthly column.
great thanks, im looking forward to that
im currently on Sammy 830 and just wanted to know if this product would give me more performance. I wanted to know what difference i will see in boot times, loading applications/games times and basically if it's worth to get PCI SSD over regular SSD in real world applications.
There's something which is not directly an issue of the review, something what you might want to forward to this site development team though. It's the slider arrows. Probably the biggest ever :) It's OK in this review but in many cases in overlaps important content. There might be an option to pick different styles with smaller arrows,make them visible only when hover over etc. I bit of CSS could easily do miracles :)
While the power usage is a little high compared to other m.2 drives, this drive is designed specifically for desktops (you can tell from PCIE adapters, to the looks of the drive, and the power consumption) not notebooks.
