我有一个配置为RAID 10（8x 2TB WD BLACK）的8托架Synology NAS。多少个驱动器可以在不丢失我的数据的情况下发生故障？
谢谢

RAID10 can lose one drive and be able to repair; in your case, you stand a 25% chance of dataloss on your second lost disk.
If the second lost drive is anything but the mirror of the lost drive, then your data is still safe, but if you have a RAID10 of 8 drives (so a striped mirror of 4x 2TB, so ~8TB logical space), then you have a 25% chance on the second lost disk of losing the remaining replica of the first lost disk.
RAID10 and RAID1+0 are similar in this regard.
Synology Hybrid RAID offers better durability through Reed-Solomon encoding and could grant you 12TB logical space with these same HDDs if that's an option to you.
