Nyland: "En vergeet het trim-commando niet", merkt Nyland op. " Servers in een bedrijf draaien meestal in raid mode. Logisch ook natuurlijk. Dus trim zal niet goed werken meneer Nyland! In raid heb je GC garbage collection op SSD's. TRIM is a function of the OS, while BGC is a function of the SSD controller. If you have two drives in RAID, each drive's controller will perform the BGC command. This action is done completely independent of any other drives (even if the drives are in RAID) and the OS. TRIM, on the other hand, will recognize the two drives as one (because the OS does not recognize the RAID array as more than one drive), and therefore won't be able to function correctly. Sandforce drives are supposed to have great BGC, Crucial drives are a close second, and Intel drives have none. Yes, unlike TRIM, BGC is active when the drives are in RAID. Dus geen Intel SSD's nemen als je raid gaat draaien.
