The advantage to both UnRAID and SHR is you can upgrade your smaller disks one at a time to increase your overall pool size. I think both would give you roughly the same amount of usable space (approx 8TB) with dual redundancy. So your 1TB, 2TB & 3TB disks would be divided into 500GB chunks same as your 500GB drives. SHR works differently, in that it'd take your larger disks and split them up based on your smaller disks. With UnRAID, for a 2 disk redundancy you would need to dedicate your 2 x 3TB to redundancy. If you want them all in a single pool, then you need to go UnRAID or SHR (Synology Hybrid Raid). Theres already many many many threads here that explain the difference between the most common, and their advantages/disadvantages Which one should I use for my situation? I'm considering to 2 HDD redundancy, in case that a maximum of 2 HDDs will fail at the same time. This NAS it will be used only for personal use, storing personal files (photos, videos and some movies).Īlso I'm lost in zfs, unraid, raid 5, shr or beyondraid. Question, what should be better to use Xpenology or UNRAID for such a NAS with this PC parts? Intel Core i3-2100 3.1 GHz (from DELL VOSTRO D11M)Īlternative: MICRO-STAR MS-7466 (from HP, i7 proc.)Ĭorsair RM850, RM Series, 80 Plus Gold Certified, 850 W I want to build a modest NAS (8TB or 12TB, if I will include the 500GB hard drives) from old pretty small capacity HDDs.
