SK Hynix Canvas SC300 SSD Review

[Guest]

SK Hynix is the least well-known NAND flash manufacturer. Most of the company's flash sells directly to the mobile market, but with increased manufacturing capacity we'll see more SK Hynix on the market.

One question that pops up when reading SSD benchmarks nowadays, especially the Real world software performance, is how much the SSD's are hamstrung by the SATA interface?
I know I'll be aiming for an M.2 NVMe model when I get a new rig next year.

How is PCMark real world?
Try transfering files, one big file, tons of small etc

The sequential write test at QD1 and QD2 show your large file transfers. The QD1 and QD2 random tests show what to expect when transferring many small files.

We like to look well beyond simple file transfers. PCMark 8's Storage Tests are traces of actual workload. The trace is replayed in the software and does a very good job representing what you would reasonably expect in a real world environment.

The rational for my question was that when looking at the "PCMark 8 Real-World Software Performance", World of Warcraft, Battlefield 3, Adobe, etc. all of them results are so alike across all the SSD's that it seems they're 'artificially' capped. Is that a SATA interface bottleneck we're seeing?

Mavikt - There is more to it than just the SATA 6Gbps bus but you are on the right track. Sequential transfers (copy and paste type operations) can be limited by SATA with large block size loads.

Most applications use small block size loads so performance can be limited by SATA's efficient overhead and Window's file system. This is why we test 4KB blocks and measure in IOPS.
