$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.

$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!

I remember a 18TB for $200 shuckable deal on BF that I missed out on. Since then, I've been waiting for something similar (under $250).

About a decade or so ago, I had two or three seagate drives go bad on me (two + a warranty replacement) so I've been specifically looking at WD

What's wrong with serverpartdeal? Are they unreliable? I do recall to beware of certain types of server drives that are managed by special controllers thus won't work in PCs. I think it was "SMR"?

Think its just the fact its used vs new so not apples to apples. I just bought 4 20TB WD HC560 for about $185 each from SPD so for me Ill take the savings as but I understand those that dont want the risk

I remember that best buy deal. I think it was for Members Only, but was supposed to open to all but then disappeared before that.

Serverpartdeal......used/refurb drives. Some people go through and get their panties in a bunch about new vs used...it's way too much of a pain to deal with a dead drive, not adding extra chance of failure into my server.

If your budget will only allow for used/refurb drives then just go with what you can do.

I agree new vs used is not apples to apples, but the price is significantly lower too. I just bought a used NVME for my laptop. I probably feel more comfortable about that then a spinner.
On the other hand, this new drive I'm shopping for will be used as an online backup drive for my plex storage so it isnt the end of the world if it dies (other than the money). I currently have a pair of 10TB, one as backup. Now I'm out of space.

Good to know I didn't really miss out on that deal I suppose

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.
Here is [was] the WD version @ $500

So unlike buying a used SSD, which one immediately determine the TBW figure. The issue with buying used HDDs is it's usually not possible to truly ascertain how heavily the drive was utilized. You can get overall on time and general stats, but not written/read utilization. Plus HDDs are susceptible to vibration and shock that can be easily experienced in handling of the drive, unlike an SSD. You also usually will not be able to ascertain that from S.M.A.R.T. stats .

Though at the end of the day you're weighing your budget vs risk tolerance in buying used vs new.

Server part deals last straw was when they sold me a new drive that had been sitting on a shelf for almost 4 years yet claiming 5 year warranty. Then selling me a drive claimed to have warranty only for them to change the listing shortly after they shipped and when I found out the drive's SN was designated OEM, without one. They did too many shady things and lost my business.

Buying new directly from WD guarantees you will have the most ideal experience of the given drive model and size. Plus you're basically guaranteed they will package the drives correctly and appropriately for shipping. An important reason why I would never buy any HDD regardless of condition from Amazon if it's fulfilled by them. They are easily the worst company at packaging that I've dealt with, and in general, not just drives.

SMR is just that the data stripe is shingled. It takes longer to write data to, so you want to avoid those, unless it's for archival needs and you won't be using it much.

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.
I'm honestly not sure. It's was a Synology setup in SHR1 using BTRFS and when I started getting data loss, I decided to migrate to UnRaid. When I put 5 drives into the UnRaid array, it reported CRC errors on 3/5 drives (all 18Tb). I don't have more info than that. WD is replacing all 3 under warranty.

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 . 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.
I did manage to pull 2 of the drive logs off before sending them in (I didn't for the first one because I didn't think to do it). Maybe it means more to you than to me. But my point is, I found it odd that only the 18Tb drives in the Syno array had issues.

Anyone know the sweet spot for $$/TB?
Are you maybe remembering the deal on the 26th of November for $200 Seagate IronWolf Pro 16TB drives at B&H Photo? That worked out to $12.50/TB before tax. https://slickdeals.net/share/iphone_app/fp/893620

Man in 2022 you could get the 15% off coupon stacked and the PayPal + discover cashback and I was getting these for 12-13$/tb. Really haven't seen anything like that sense as most deals are usually over $15/tb
