SNV3400 alternative

I have a DS1621xs+ device and I'd like to buy some M.2 NVMe SSD in order to have SSD cache in the device.
Synology recommends their SNV3400, but this SSD - unlike its 'big brother' SNV3500 - has no PLP (Power Loss Protection) which is quite essential for me.
Ufortunately SNV3500 doesn't fit to my device because of its size.

So I wanted to find an M.2 NVMe SSD (tpye 2280) from another vendor with PLP function, but I only found one: Kingston DC1000B. This would do the job, however its random write speed is very slow comepring to Synology SNV3400. (20.000 IOPS vs. 40.000 IOPS).

Do you know about any other M.2 (2280) NVMe SSD with PLP function?

Thanks in advance!
