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 RE: ?? -- Raid card. - lingu - 06-14-2020 11:32 PM Pls turn this into an overview of raid card so as to maximize its value.

W1. extend the SATA ports? W2. Using Raid card to raid some HDDs to get data redundancy?
