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

  • Be careful about the seller MD TECH
I bought this item twice. The first one was received without much problem, and in the second one I didn’t realize the Amazon app defaulted to another seller and I didn’t notice this until I checked the SMART status after I received it. The SMART status was cleared out, which is totally unacceptable. The attempt to hide past stats and history is not only disgusting but also makes users not able to evaluate the reliability of the drive. There could be past relocation sectors and uncorrectable failures, which are important indicators that the drive won’t last long so user should be prepared for that. Update: I ran SMART self test on the drive. It’s been several days and it still says 90% remaining (immediately after the self-test started it already reported 90% remaining), which means the self-test is likely stuck. This didn’t happen for my previous drive from a different seller, which completed in about 2 days. ... show more

  • Works Great!
I bought two of these for my Plex server. Installation was easy - I did have to tape off a power terminal, but the instructions were perfect. They formatted perfectly and have been working great!

  • Just know that not all of these are Gems like on LTT.
Yes, I also saw the LTT video, and decided to jump in and try my hand at some of these for my Unify NVR. grabbed two for a great price -- which I'm happy about. The drives are in great condition, and packaged perfectly, Even come with a power cable. Buuuuuuuuuut... Unlike the low hour "Appears to never of been mounted" drives they got on LTT, mine came with 29,345 and 26,699 "power on" hours. Not a deal breaker, in fact I'm happy with the fact that they didn't reset it as part of the "Refurbishment" -- But now I'll most likely end up buying a third drive just for extra, extra, extra insurance, which starts moving me awfully close to the cost of just buying new drives in the first place. ... show more
