Description

Laying the foundation for a worry-free data center, HGST delivers capacity to conquer the data explosion – Ultrastar He12 HDD. Designed to handle workloads up to 550TB per year, the Ultrastar He12 HDD is the industry’s first 12TB drive and uses PMR technology to make it drop-in ready for any enterprise- capacity application or environment. The stable internal environment created by fourth-generation HelioSeal technology enables a new 8-disk design, increasing the capacity by 20% when compared to the 7-disk design of the prior generation. This highest capacity helium drive offers the lowest power profile in the industry to help data center architects meet eco-environmental goals and requirements. Targeted at 2.5M hours MTBF, the Ultrastar He12 HDD provides the highest reliability rating available of all HDDs on the market today by building on the successful design of its 10TB, 8TB and 6TB predecessors. Trust HGST and the Ultrastar He12 HDD to deliver more capacity, more efficiency, more reliability and more value to your data center. This drive includes a “Power Disable” feature which allows the host system to easily power cycle the drive to perform a hard reset. Ensure that your system will support this feature.

    • Great value, even if there is a snag - I would buy more again!
I am writing without the help of ChatGPT (I know, weird concept, huh?) so this is totally authentic. I bought 4x of these for a used Western Digital PR4100 NAS I bought off of ebay (Western Digital nix'd the product; they don't sell them new anymore - but it as an excellent NAS compared to others). At first, all drives joined the set just fine - no SMART data issues to report, not a peep for a day or so. I was doing the happy-NAS dance because of it. Buying 4 at the same time makes sense when you do this since the best practice with RAID configurations usually have the same model of drive across the entire set so that there's no timing inconsistencies when writing data (which can foul up the RAID quickly). So I setup everything right. But on day 2, I had one of the drives fail on me - so said the NAS, so when I investigated it, it turns out that there were some sectors that were "bad enough" to warrant the NAS to taking the drive offline. I went through Amazon's replacement process (which is awesome, BTW) and once I dropped off the drive at the UPS store, a replacement one was FedEx'd to my house. I got it the next day. So it's better support than most IT companies frankly, and 10x better than CDW. I'm not sure how long non-Amazon tech businesses compete anymore; it's hard to beat that kind of service. The supplier was the one who sent it (not Amazon) and they did so so quickly and it came packaged so nice (it looks brand new in every way; if it didn't say 'renewed' in this listing, you'd never know). I put in the replacement drive and whallah - it works fine. Moral of the story: buying renewed drives can *feel* scary. But in my exhaustive experience buying harddrives - and I've been doing so for 35+ years (I bought MFM drives and would convert them to RLL just to get 1% extra storage back-in-the-day), even when you buy new ones, there's about a 10-20% chance that it's DOA. This is not a manufacturing problem per se - but imagine yourself in the life of a harddrive, these get kicked around by the sorting machines that the likes of UPS, USPS and FedEx use as well as LTL Freight services, so the mere fact that they work after being shipped is a miracle. So that said, I had the around the same luck with these drives as I do when buying new drives but here's why I actually think this is better: when there is a problem, at least the Amazon/Seller combo I used, you get a replacement drive *the next day*. When you buy a new one and go through the manufacturer - don't hold your breath as it's like 1-2 weeks. And while, yes, you could always buy a new one through Amazon and have a quicker turnaround, this is $100 cheaper per drive than buying new. So save your money, buy this drive, and realize that with any hard drive new/refurb/used, you will have the likelihood of it not working from the get-go.. at least buying this refurb here, you are actually getting better service for a lower cost, which is a total win for the customer. Lastly, these drives are performant and actually have superior stats to new ones of the exact same model! Especially if you are using them in a NAS, these are a no-brainer; and they power save and all of that stuff (and I didn't use the tape or had to convert the "pins" for an older setup but all of the stuff to do that is in the box when you buy it). A+++! ... show more

    • Failed right off!
Ordered and placed in External SATA Case. Quick Format worked fine, and drive recognized. Soon as I copied more than a couple hundred GB of data, drive failed. Tried doing a proper format, wouldn't do it, fails and reverts to RAW Requested replacement, only giving them two shots to make this work then refund. (Update) Second drive arrived, took 24 hours to format (not quick format) as NTFS, in external case and power, using USBC connector. Succeeded in format. - Started copy, again first few hundreds of GB (below 1TB) succeeded then drive went offline (required powering off then on again). Sitting in case on table, plenty of ventilation. - Started second attempt to copy, but now as it trying 'past' those initial first few hundred GB fails right off and won't copy. As seeing other comments these are all bad/worn out drives, not "REFURBISHED" to Amazon standard and non-functional/unreliable. PASS ON THESE - DO NOT BUY! ... show more

    • Great drive for the price!
At first the drives wouldn't spin up, but I didn't take the time to read the information on the drives. They had very good instructions on overcoming the no spin up problem with older chassis. They even included a special jumper so you wouldn't have to come up with your own solution. Great price for a solid drive that works great for a media hub. I bought two of them so i could mirror them to secure my data in case one of the drive fails. So far they work perfect and are performing really well. ... show more

    • High capacity at a great price
I have purchase about 10 of these over the past year. None have failed though one had a few bad sectors. They have a lot of hours but that’s to be expected.
