Ooo I recognize this as the ssd in the Dell 7440s we just bought at work (256 gigabytes).
When your sequential read is basically the limit of SATA and you are pushing 9000 -12000 iops at a queue depth of 1 - 2 the bottleneck is no longer the storage device, it's the storage interface, SATA.
Having said that the only way to really compete is:
1. Battery Life (40 minutes is noticeable between this drive and the Samsung)
2. IOPS at a queue depth of 1 - 4 (Basically so you can put a higher number on the packaging)
3. Write Speed
I use a Patriot Memory 256GB Supersonic Magnum 2 with the Windows 7 Bootable install and I'm able to install a fresh Windows 7 in about 10 minutes on a computer with this ssd.
Windows update is blazingly fast.
I use this combination to create WIM images that I capture for use on other computers.
The read speed of the flash drive, 400 MB/s, is faster than the write speed of the Sk Hynix 261 MB/s.
I would have rathered a Samsung 960 Pro or even a Samsung 850 Evo, but I'm just glad Dell didn't give us an ADATA ... (with that write speed 62 MB/s)
We've had Sata 3.0 since 2009.
Hopefully we can see some SATA 3.2 motherboards / ssd releasing soon.

NVME / m.2 is faster but you are limited in the amount of drives that can be attached to the motherboard.
