( i'm old Apple Raid user ) So yes - I install SOftRaid XT ( leaflet says SoftRaid - but lite version rejects enclosed code) I initialize four 500 GB sticks ( 3 are directly / unformatted - I format one beforehand in AFPS just to test if the enclosure recognise it ) and create Striped ( RAID 0 ) volume with 2 partitions 1 TB each . All is good to start with - initially very good performance measured (around 2000 MB / s ) ( empty ) Unfortunately - after first tries to copy stuff from my original disk I get i/o error dialog from SoftRaid - It says Disk 3 is failing. After a verification process from SR - I get I/o errors on 2 disks now - But the numbers of the disks are changed . ( like 5,6,7 ) After restart I get a finder Disk error as well. Thank You for any suggestions . 2017 Imac / high Sierra - OWC Express 4 M2 connected with T3 cable ( I have another T3 external drive in the chain - but Express comes first ) I cannot attach original d.supt document created directly after problems occur - as it was exceeding 1MB limit. So i made another document - this time it is under 1 MB but the forum tool says it is invalid type of attachment. ]]> High Sierra Issues Jann Lipka https://forums.softraid.com/high-sierra-issues/new-express-4m2-unusable-with-softraid/#post-2785 https://forums.softraid.com/high-sierra-issues/new-express-4m2-unusable-with-softraid/#post-2784 Sat, 21 Jul 2018 22:08:03 +0000 High Sierra Issues SoftRAID Support https://forums.softraid.com/high-sierra-issues/new-express-4m2-unusable-with-softraid/#post-2784 https://forums.softraid.com/high-sierra-issues/new-express-4m2-unusable-with-softraid/#post-514 Sat, 21 Jul 2018 20:39:44 +0000 High Sierra Issues Jann Lipka https://forums.softraid.com/high-sierra-issues/new-express-4m2-unusable-with-softraid/#post-514
