Sorry to revive a dead thread, i have now after careful thought bought this card. I have a OWC Aura Pro X2 2Tb as the main middle 'Apple' drive, flanked by a pair of Sabrent 2Tb drives giving me 6Tb in total.
Using AJA System Test , All three drives perform well
The OWC performs at 1410 Write and 1421 Read
Sabrent 1 performs at 1364 Write and 1414 Read
Sabrent 2 performs at 1367 Write and 1414 Read
No noticeable difference in fan noise, Same annoying Red light on bottom of card taped over
The Sabrent 2Tb drives are good value on Amazon UK @ 189
Added 128Gb OWC ram into the pot and its a little beast now
Not really a Newbie either, just never post lol
