Looking for a new raid card which is mainstream in 2020 with fair price.

I search for some ranking website of raid card:
https://www.6to23.com/raid-controller-cards/
https://www.msn.com/en-us/lifestyle/rf-b...rs-reviews
and chinese website : http://top.zol.com.cn/compositor/raid_crad.html

Looks HP RocketRaid 640L is the value one. Speed 6.0Gbps per SATA port
around 410-610 RMB on Taobao,
can't find this card in JD.
65 USD on amazon

Our CDMR9460---RAID卡 9261-8i is still a great part. maybe Raid card not really improving.
869 RMB on taobao
180 USD on amazon

Also LSI MegaRAID SAS 9211-8I is another great one, but this card need PCI port. Speed 8-port 6Gb/s SATA
365-599RMB on taobao
can't find on JD .
98 USD on amazon.

If we need cheaper one with 2 SATA port we can choose HP RocketRaid 640L
But 9261-8i is a anchor point, cheaper means lower functional.

yujia -- please kindly comment
