PCPer File Copy Test
Our custom PCPer-FC test does some fairly simple file creation and copy routines in order to test the storage system for speed. The script creates a set of files of varying sizes, times the creation process, then copies the same files to another partition on the same hard drive and times the copy process as well. There are four file patterns that we used to try and find any strong or weak points in the hardware: 10 files @ 1000 MB each, 100 files @ 100 MB each, 500 files @ 10 MB each and 1000 files at 1 MB each.
Well now, those figures are certainly impressive. File creation and copying for the 512 and 1TB models is right up there with the Intel SSD 730's fire breathing overclocked enterprise controller. The 256GB and 128GB models progressively fall off as the available die count is reduced by those lower capacities (meaning the controller has less dies to spread writes across, which slows ultimate write speeds). The older SandForce driven SX900 is handily beaten, yet still bests the SP920 of the same capacity – most likely due to the fact that our copy test is compressible data and the SandForce controller is not physically writing as much data to its flash in order to achieve the measured speed.
Great to see a new entry in
Great to see a new entry in the 512GB/1TB market. I would argue that now the major data-destroying bugs have been worked out of the SSD controllers, the major factor in the consumer market is price/GB. I’m hoping this new entry helps to force prices down further.
we are ever so close to the
we are ever so close to the ssd sweet spot, which i think is about $0.30-$0.35. $300-$350 1TB , or more importantly $175-$200 for 500GB is the point where fast silent ssd technology will be viable in every mainstream system, leaving the spinning drives for ultra budget systems and those of us who need crazy TBs of storage.
It’s good to finally see a
It’s good to finally see a competitor for the Samsungs and that there is actually a trend to give a price break to go larger. However, the main thing I worry about is reliability with these things. Only time tells the truth there. Glad you led off with the controller.
The 512GB version would be
The 512GB version would be fantastic in my new SFF build but it is a bit overkill considering I have a 2TB WD Black in there. These seem very promising.
I’ll take two 256 GB ones
I’ll take two 256 GB ones (instead of 1 512 GB one) please. #IfYouKnowWhatIMean
Despite the slightly slower
Despite the slightly slower writes at that capacity, it's still a better way to go if you can go RAID-0.
