Sequential Steady State
128KB Sequential Mixed-Workload Steady State Performance
In this section, we look at steady state performance - where the drive has been worked into a worst-case scenario. Under normal workloads, this is a difficult state to achieve. But taxing video manipulation with heavy sequential writes can cause this type of performance.
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.
