Hard drive size sweet spot may be 18TB, Sept. 2021


Recommended Posts

What hard drive purchase makes sense today, Sept. 2021? 

For me, it is 18TB Seagate Exos, w 5yr warranty.  Amazon $400.  ($22/tb)

 

Shucked drives?  Currently I am seeing no bargains.  Back in July Aug. 2021 Costco had Seagate 8TB for for $130  ($16/tb).  Now everywhere seems to be $170 ($21/tb).  No warranty when shucked.

 

Internal w 2 to 3 yr warranty: Also currently 8TB for $170  ($21/tb).

 

Why do I prefer to pay $22/tb for an 18TB vs waiting for an 8TB sale ($16/tb)?  Because:

     1) 5yr warranty

     2) Lot more TB in a single unraid enclosure (tower or case).

 

Of course all of this may not apply to those who do not need more storage to fit in their enclosure.  

I only buy Amazon as last resort, since power corrupts.

 

If anyone knows what is going on with the Amazon seller "Seagate Store": Is it the same as "Seagate Technology Inc."?  When I did online warranty check on the serial of the 18TB I received, it did show 5yr factory warranty.  But I am curious if this is a way for the factory to circumvent the dealers and compete with their own dealers?  My guess is they use a loophole in the dealer agreement, by creating "Seagate Store" as a company, and we do not know if it is the same owners?

 

I gave up on trying to figure out which of the 3 major makers make more reliable drives.  So I buy the cheapest which tends to be Seagate more often.

I see some slightly older model Seagate Exos X16 16TB drives around $325 or around $20.32 TB.

 

I see some saying the warranty starts from date of manufacturing and not date of sales. It all depends if you get an OEM or Retail unit. That seems rather difficult to find out on some of the Amazon listings. I also see statements where "The limited warranty extends only to the OEM and may not be assigned or transferred without Seagate’s consent."

@xrqp did you order from "Seagate Store" which now shows as HyperHawk storefront on Amazon? I've been going through the Q&A on the X18s and X16s trying to figure out which resellers are with full 5 years and which are OEM meaning no direct coverage from Seagate.

 

It's a bit of a hassle, but its a savings of $75 for 1 drive or $225 for 3, which I'm looking to pickup. I'll definitely need to setup Parity Tuner if I expand to 16TB or 18TB drives.

 

 

 

I had a power outage last week Thursday that killed an 8TB drive completely, despite being on UPS. It won't power up even in other systems or enclosures. The other 3 drives are fine. I ordered an 8TB drive that could be delivered Friday. The preclear took 33-35 hours for 1 Pass to ensure the drive was suitable. I started the data rebuild this morning. Should be finished in another 6-8 hours. It will be nice to be back on a protected array.

I don't consider SMR drives to be a bargain, even at $130 per 8 TB prices.

Yes.  I did not even notice until you mentioned it, but my order record shows it is from HyperHawk.   I would be upset about the switch (if it was a switch or hidden), except I got the 5yr factory warranty, so it is OK.  Ordered Aug. 30, recvd Sept 6, warranty to Sept. 30, 2026.  I think they go by mfg date plus 1 month to sell, plus 5 yr., or something similar.

It is difficult to know if you are getting factory warranty, or dealer warranty which is more risky.  In this case, if Seagate factory did not show for the serial number I received, I would have returned it.  But it is scary since the listing does not say "factory" warranty.

Is Exos an SMR?  If it is not SMR, then that's one more reason it is a sweet spot for me.

I was referring to the 8TB drive sold by Costco.

There are currently no SMR drives in capacities of 10TB and larger.

With the exception of the recently announced Seagate 20TB model (still unknown at this point when it will hit retail)

You are correct, this Exos is CMR.  Here it the Amazon listing title:

Seagate Exos X18 18TB Enterprise HDD - CMR 3.5 Inch Hyperscale SATA 6Gb/s, 7200 RPM, 512e and 4Kn FastFormat, Low Latency with Enhanced Caching (ST18000NM000J).

All of Seagate NAS (IronWolf/IronwWolf Pro) and Enterprise (Exos) HDDs in any capacity are always CMR.

For me it would be because Seagate 8TB externals are SMR drives which are not even worth $10/TB in the NAS environment, IMHO.

I have had disk errors and disk failures lately, and it seems to be with 8TB SMR drives (mostly shucked).  On-line I only see info about how slow they can be.  Can't find much about failures.  But I think they fail more too, and fail within about 2 years.  I am regretting them.

I have ~60 harddrives with 24 of them being 8TB Seagate Archive drives that is using SMR technology. They are all 8 years old and not a single one of them have failed so far, so I do not think SMR have a general failure problem. 

 

These Archive drives are actually the oldest drives I have. The rest of the drives is a mix of Western Digital Red, Seagate Ironwolf and Exos ranging from 8 to 18TB. I have had failures in all of these series of drives. but nothing out of the ordinary. In general I consider all of them quite stable. 

 

But it is a small sample size. Would be interesting to see some larger statistics on this.

For me it is mostly either Seagate Exos 18TB or Toshiba MG09 18TB Series of hard drives. Here in Europe they are priced very similar and they both comes with 5 years warranty. I prefer these larger drives for the same reasons as you and would like to add power consumption. Larger capacity = Less drives = Less hardware (HD's, HBA's, Cabinets etc) = Smaller electrical bill.

Hey RecycledBits, thanks for your post.  I had not thought about the energy saving of one 18TB vs two of 9TB, but it makes sense.  

 

I would give more weight to your experience since you had a lot more drives than me.  Were many of your 8TB SMR used in unraid array? 

Not sure if that makes any difference.  Other posts said SMR worked very well in unraid.
