[QUOTE="CyberSimian, post: 1137861, member: 141969"] I would like to suggest a slightly different solution. :) Your DS1512+ has 5 slots, and you will presumably use RAID5 (or Synology Hybrid Raid). One disk is used as a "parity disk", so you end up with a data space of 4x3TB = 12TB. In contrast, if you purchased 3x6TB disks, one disk would again become the parity disk, giving you a data space of 2x6TB = 12TB. So you would initially end up with the same usable space, but the difference is that you would still have 2 slots free, for future expansion (in, say, 2-3 years time). When I set up my DS1515+ a few weeks ago, I found that it was possible to find in the UK several sellers where the price per terabyte was virtually the same for all disk sizes (so no price advantage in buying the smaller disk sizes). So I chose 6TB WD Red disks for my DS1515+. You can never have too much disk space. :D I realise that the initial outlay is greater (3x6TB will cost more than 5x3TB), and the special discount that you can get on the 3TB disks may sway the argument in their favour, but I thought that this alternative was worth considering. If this alternative seems appealing, you shoud check that your DS1512+ supports 6TB disks, and that it can create a volume larger than 16TB (some of the older/smaller Synology units have a volume limit of 16TB). -- from CyberSimian in the UK [/QUOTE]
