notamment chez ADATA sur les SSD en M.2 NMVe ...

this new feature can offer better performance than regular SSDs, with less overprovisioning and less DRAM

ce prochain modèle est attendu pour pas moins de 6500 Mo/sec en lecture et 5000 Mo/sec en écriture..

pas tant de gain en pratique ... car ce ne sont pour l'instant pas des SSD beaucoup plus performant
