UnverifiedNAS用SSD应优先选择DRAM缓存版本，无DRAM(HMB)的固态盘在NAS多任务并发和随机写入场景下掉速严重，长期读写延迟明显高于带独立缓存的型号80% similar Unverified机械盘阵列若要跑虚拟化或数据库随机IO，必须配SSD缓存(读写缓存)或SSD Trim/Tier存储池，纯HDD的RAID在随机小IO下IOPS极低会拖垮虚拟机响应75% similar UnverifiedSSD缓存或全SSD NAS虽快，但机械硬盘阵列在千兆/2.5G网络下已跑满带宽，除非上万兆(10GbE)否则SSD高速优势体现不出来，家用普通场景机械盘足够75% similar Unverified读写速度对NAS存储盘意义有限，因为绝大多数NAS走千兆网口(约113MB/s上限)，只有2.5G/10G网络或SSD直接做缓存时高速盘才能发挥价值74% similar UnverifiedNAS硬盘应选专用NAS盘（如西数红盘Plus/希捷酷狼），其针对7×24运行和RAID振动优化，普通桌面盘长期运行故障率更高74% similar
