Yapt

Yapt (yet another performance test) is a benchmark recommended by a pair of drive manufacturers and was incredibly difficult to locate as it hasn't been updated or used in quite some time.  That doesn't make it irrelevant by any means though, as the benchmark is quite useful.  It creates a test file of about 100 MB in size and runs both random and sequential read and write tests with it while changing the data I/O size in the process.  The results are a good look at overall drive performance.

Starting at the bottom, sequential write spread plainly points out the write speed tiers of the bottom half capacities of the SP920. Reads are looking good for both sequential and random. Random writes never play well with SSDs on this test, as they may not be 4k aligned, and that effects various SSDs in various ways, as noted by the Intel SSD 730 taking an unexpected (and unrepresentative of real performance) nose dive. Lesson: ensure you align your SSD partitions or bad things happen.

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 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 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 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 (instead of 1 512 GB one) please. #IfYouKnowWhatIMean

Despite the slightly slower writes at that capacity, it's still a better way to go if you can go RAID-0.
