$274.99 per unit for those without a calculator. I just bought a 16TB Red Pro with a 10% off coupon for $288 (before tax). Decent deal if you need two!

Aye. Thanks for confirming. I could have sworn there was a BF deal for cheap $$/Tb, but nope.
Anyone know the sweet spot for $$/TB?

$15/tb was the sweet spot. Haven't seen any shuckable (easystore) deals from bestbuy in the sub 15/tb in a while

Hopefully all the people "just go to serverpartdeal and blah blah..." dont chime in.

Just ordered yesterday 18TB EXOS from newegg last night for $255 each. Not sure how these compare with the Seagate drives, it looks like at least the cache size is doubled on the WD. Kind of wish I waited for this, getting OEM drives from newegg is sometimes dicey.

Best deal at the moment for someone needing 2 and cant wait for something better. Obviously for those that want to shuck you can get 18tb for 200 or less from BB on many occasions a year.

Bought these for the very specific purpose of them being the largest WD red drive supported by a qnap TR004, which I use as a raided external backup drive. Thanks for the post, been waiting for something along these lines to pop up for the 18tb red pro

I'm sure it's just an isolated incident, but I just had to RMA 3 of these drives for CRC errors. My Synology had a BTRFS hiccup and decided to corrupt some of my data and when I migrated to UnRaid, it kicked back CRC errors all over the place (which Synology didn't report). WD was cool about the RMA, but my other Red Pro (3x 8Tb) drives weren't affected. Only the 18Tb drives…

Thanks for the deal but Exos drives are $4 more all day. Wish WD would cut the prices down a little more.

Crc where? In the raid stripe? Software raid.. was it comparing the data with the parity? To get crc errors you typically have to compare the data that was attempted to be written then read it back off and see if it's the same sometimes in combination with some hashing. I have had 4 synology machines. Each of them 8 drive versions. Could you supply more info please? Thanks.

Adding a bit more. Sorry I am a storage guy and i want to buy some of these drives but losing that much data and/or the rebuild time or having to go raid 6. Maybe its time to get another array just for testing Smilie

. Anyway…. Synology validated some seagate drives and they kept falling out of the raidset I was just using ext4. (Synology doesnt have a hardware raid controller its all software). They validated the drive but only a specific version of the firmware which they didnt document. They couldnt supply the firmware. I think it was c51 and i was running c52 or something like that. Having 8 of those things was expensive. Turned out to be head-parking etc. power management stuff was too aggressive. It caused raid consistency errors. Most of the time CRC errors are either raid stripe data or a controller/cable problem. Synology doesnt really expose anything interesting in the logs in the interface. You have to log in via ssh and start digging around in /var/log etc. to find anything interesting. Did you long format the drives or long initialize them in the unraid box? How many drives were in it?

Errors that the drive logs it will typically remap those sectors. Silent bit corruption happens rarely on drives. I saw once where a solderball on an asic for a fibre channel storage array was causing multi-bit flips. Another one was raid controller firmware was corrupting data on a san volume somehow. One of the latest weird ones was writing data to a san volume would work fine unless it was sent to the server over the network via nfs then written to the san drive via a fc hba. Writing it directly to the drive didnt cause the issue. I stopped paying attention to that one when redhat started rewriting code. I think they addressed it with some scatter gather fix but they never explained why it would just do it with nfs. Ohh something else i did was you can build a synology VM. I was doing it in esx and i had a bunch of hard drives I had to manually make RDM disks then map them to the synology vm and let it do its software raid thing. That way I could put them in a synology array and it would boot up. Doing snapshots in vmware then screwing around with the bits and/or learning how to mess with the raid set without risking blowing up data was fun too. Im done, cheers.

In case anyone was wondering, i got 2 for $500 around May 2023. During Amazon Prime day, this has went down to $240 for one. B&H also had that same deal. I believe that is the cheapest I have ever seen it.
