If you are trying to build a NAS or similar then my suggestion is go with shucked WD EasyStore externals, you need to either use molex to sata power to bypass the 2.2v issue or tape the pin but they are WD Whites inside and work very well from my experience. I just keep waiting for the 14TB's to fall a little further so I can replace one of my 5TB parity drives with that so I can grow my array.

Shucked drives aren’t necessarily cheap, bare drives are always cheaper in my country

  What country is that if you don’t mind my asking? Unfortunately, in the USA shucked are often cheaper than bare. I wish bare were cheaper b/c you void the warranty when you shuck..

Looking to build an inexpensive DAS array. Any other good ideas for storage/connectivity?

  I might not be the best person to ask. I’m running 3 servers at home currently that are all desktop towers. With a 3->4 (3x5.25”->4x3.5” [0]) converter I can fit 12 drives in each tower. Across all 3 I have just over 150TB. There are some nice server chassis that can handle 20 but I’m more comfortable with tower hardware and when I hear “SAS backplate” my eyes glaze over... I’m a big fan of UnRaid for my server OS but I know it’s not as advanced as some offerings on the market. I enjoy it’s ease of use and management of VM’s/containers. I’m happy to share more if you are interested. [0] https://www.amazon.com/dp/B00DGZ42SM https://www.amazon.com/dp/B00DGZ42SM

> you need to either use molex to sata power to bypass the 2.2v issue or tape the pin You mean the 3.3v issue. In most cases, you can also just clip the 3.3v wire that goes to the sata power connectors from your power supply. It's orange, you won't be missing out by not having it anymore, and it's easy to clip with wire cutters. You should put a dab of electrical tape on the cut ends, but a clean cut isn't likely to short on anything. Consider it updating your power supply to the latest SATA spec. Some people do have sata enclosures that provide 3.3v, and they may need tape on their drives, or something more drastic.

  :headsmack: I couldn’t remember the right voltage and I googled “2.2v” and I found a few reddit threads and assumed that was correct. 3.3v is the right number, thank you for correcting me. Yeah I bought some tape to cover the pin if needed but I found the molex cables to be easier, I didn’t know you could just cut the wire, I feel stupid now lol.

    Well, now you know; I found a couple people mentioning it in different forums, but there's a lot more posts on reddit, and I didn't see it mentioned there.

Isn't that a bit totally though? I've heard that old one: molex to sata lose all your data
- joshstrange 7y ago
  I don’t think I’ve heard of this. It’s only the power that the cable is providing and I’ve been running for months if not 1-2 years without issue using this setup.

> tape the pin Been there, and it's worked well, but I did some research and used kapton tape. It's thin, and designed for use in electrical applications needing resistance.
- joshstrange 7y ago
  Yep, I’ve got a few rolls of Kapton tape sitting next to my desk. I haven’t used it yet since I just used the Molex to Sata cables for all my shucked whites.

I believe this issue is only for certain NAS devices, or maybe only certain versions of the drives. For reference, my Synology DS2015xs didn't require any modifications to the four 10TB WD EasyStore drives I shucked that I grabbed from BestBuy.

  It happens when drives are compliant with SATA 3.3+, but not the power cable: https://en.wikipedia.org/wiki/Serial_ATA#SATA_revision_3.3 https://en.wikipedia.org/wiki/Serial_ATA#SATA_revision_3.3 > Power Disable feature allows for remote power cycling of SATA drives and a Rebuild Assist function that speeds up the rebuild process to help ease maintenance in the data center. > The new Power Disable feature (similar to the SAS Power Disable feature) uses Pin 3 of the SATA power connector. Some legacy power supplies that provide 3.3 V power on Pin 3 would force drives with Power Disable feature to get stuck in a hard reset condition preventing them from spinning up. The problem can usually be eliminated by using a simple “Molex to SATA” power adaptor to supply power to these drives.
