SK Hynix Canvas SC300 SSD Review

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.

Early Verdict

SK Hynix is already showing what it is capable of doing. Armed with LAMD IP and NAND flash production, the company can be a major player in the SSD market. 2D planar NAND is on the way out, so Hynix will need to ramp up 3D production to take on Samsung with equal footing.

Pros

  • +

    The SK Hynix Canvas SC300 delivers mainstream performance for near entry-level SSD prices. The heavy-workload performance is better than that of many mainstream SSD products currently on the market. The five-year warranty is a nice addition, and it matches the 850 EVO's warranty but not its endurance rating.

Cons

  • -

    The low 72TBW rating is half that of the Samsung 850 EVO, but the price doesn't represent the shortcoming.

    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.
