HGST Ultrastar He8 HDD HUH728080ALE604 8TB 7200RPM 128MB Cache SATA 6.0Gb/s 3.5-inch Enterprise Server Data Center Hard Drive (Renewed)

Great value, I'd far rather have a used Ultrastar than a new SMR drive. Bought a couple of Seagate drives for a new NAS without realizing that they were SMR. Within 2 weeks, I was noticing performance issues, especially under heavy usage. Adding a new drive to the NAS took days. Running an integrity checkup on a backup? Yeah... painful.Wasn't sure about buying used/refurbished drives, but once I finished replacing the Seagates with these, I was a convert. Zero SMART errors on any of the 5 drives I've purchased so far, zero slow-down even after filling the drives to 75%+ of capacity. Only complaint I COULD make is that they are a bit loud, but they're enterprise-class drives and so I expected that. Mine are in a Synology NAS which is in the closet about 6 feet from my desk. I can definitely hear them, but it isn't annoying, and isn't any louder than the rest of the networking equipment in the closet with them.FWIW, Backblaze named these among the most reliable drives that they have in service. Hard to argue with that.

Solid hard drive. I haven't had it long enough to say anything about its long-term durability, but here are some objective specs & details. (which for some reason were left out of the product description on amazon, as well as the actual data sheet PDF from HGST) Average speeds are in the attached photo. On arrival I tested for bad sectors and other errors. The drive was completely clean and safe to use out of the box. Physically, the drive (refurbished) was totally spotless as well. You always wonder why refurbished stuff got returned obviously but I haven't seen any sign to differentiate the drive from a brand-new drive. As for my opinions - I like the idea of helium drives for RAID arrays. They are technically denser, because helium reduces friction, allowing drives to be packed closer together, which in turn allows them to put SEVEN disks in this thing. But as of right now, HGST isn't really taking advantage of that, drawing fewer bytes per disk than normal 3 or 4-disk drives. In the near future that will probably change, and when it does helium drives will have the highest capacities you can fit into a 3.5" magnetic disk drive. But for right now, the highest capacity consumer helium drive from HGST is 12TB, so it's directly competing with Seagate's 12TB non-helium drives. And those 12TB drives are virtually impossible to find on retail. You can either order them wholesale or you can pay well over a thousand for a used drive on eBay or something. So that's obviously not the reason to pick up a helium drive.The area in which the helium drive wins out versus the Seagate drives is its mechanical efficiency. The drive requires less power per byte AND less power per byte per second. Up to about 20% actually. Not only does it require less power in operation, but even if it were set to operate at the same wattage, it produces less heat. This is really important if you're going to have lots of drives in close proximity, like in a RAID array. If you're looking for a drive for a NAS server or even a dense drive bay in your PC, this one's great because it allows you to run fans at a lower rate. For my applications, this was really important. I put three 5x3.5" drive bays in the front panel of a full tower, for a total of 15 hard drives, all running off just three small fans. Realistically, this setup could still safely cool regular drives, but the issue has been noise. I'm still looking into replacing the fans in the drive bays with quieter, higher-quality fans, but for the time being I'm stuck with these super noisy fans. The drive bays have a switch allowing you to swap between high fan speed, and low fan speed. The high is incredibly noisy, and the low is only slightly quieter. The noise quickly gets overwhelming on high speed, but in this setup, running non-helium drives on low speed is only safe for normal operation, where most of the drives are effectively sleeping. If you start any kind of major write operation (1TB+) on the RAID volume which recruits 5 or more drives, the temperature quickly goes up to 50-55 degrees celsius. This is a safe temperature for the drives themselves, but they're not just in a little storage enclosure. If you're using the drives for an NAS server or a massive PC like mine, your drive fans will likely end up blowing hot air all over the rest of your components. Since my system is air-cooled, the CPU and GPU are cooled by fans which pull air from inside the case. That arrangement depends on the air inside the case actually being colder than the CPU/GPU, obviously. You could say that means it's a bad setup, but 1) there isn't really another way to fit 15 drives into a PC tower case, and 2) most hot-swappable server systems position the drives in front as well, so in practice this is an extremely common cooling arrangement, just more for rackmount systems than for desktops.Anyway, the arrangement works just fine with the fans on low, and especially when the drives themselves only ever reach 40 degrees. Sorry it was so long-winded - that is the real benefit of the helium drives, in my experience. So the only concern I had left was the price. Helium drives are more expensive per TB than other drives, as well they should be, since the technology is more complicated. They aren't just pumping helium into the drive and hermetically sealing it. The main advantage of helium is that it allows them to put a completely different mechanism inside the frame. Like I said, 7 super thin disks, and thin write heads and arms. So the price jump is fair, since you're not just paying for the cost of pumping and sealing the helium inside, but also paying for 2-4 extra disks and the R&D that goes into designing the thinner mechanism. Still, the issue of price comes down to whether it's worth it to you, not whether it's technically fair for the manufacturer to charge more. That's why I bought the refurbished drive instead of the new drive. I started with just one because I wanted to test the quality and reliability. So we'll have to see if I have problems in the future, but based on my initial experience it seems like you get way more than what you pay for. This drive is less than $25 per TB, which is extremely low. In the ballpark of the lowest quality drives. Here you're getting better performance in just about every way than the top quality drives from Seagate, for at least a 15% lower price. The only issue is whether the drive being refurbished really matters. But what really sealed the deal was the 3 year manufacturer's warranty. If you buy this drive brand-new you only get a 1-year warranty. But because it's used, you get an extended warranty for free. Now obviously if your drive breaks down you're likely going to lose the data on it, so if you intend to use it as a simple volume, then the warranty may not matter, since replacing the drive won't replace your data. But if you're using it for a redundant RAID volume like me, this is just fine. If one of my drives breaks down, no worries, the other 4 can pick up the slack while HGST sends me a replacement... If this thing falls apart in the next 3 years, I'll be just fine. After 3 years I'll probably have moved on to a new system anyway.So for the money this is really the best value you can possibly get if you have any need for RAID storage. Obviously these read/write speeds pale in comparison to any SSD, but if you're trying to build a high-storage PC or storage server, you're going to need HDDs, period. I chose samsung 960 pro for the boot & cache drives, and there's no reason to go beyond that for me. For the high-capacity, relatively colder storage component of your PC, or for your NAS server, this is by far the best value I have seen anywhere. For all the other components in my system, their high quality and performance justified spending outrageous sums of money for the top tier parts. But when it came to hard drives, I was able to buy the best hard drives I could find, for a cheaper price than some of the WORST hard drives I could find. Really a rare deal, and I'm hoping it doesn't just go away immediately.

UPDATE: I had 2 drives start throwing SMART errors at the same time (not a full on failure yet). Used spare drives to rebuild my RAID configuration and sent the old drives out. 2 weeks later I received replacements. One of the replacements was one of my original drives. Avoid.Original reveiw:The good: Drives all work and function as you would expect. Full drive scan passes with no errors. Purchased 4 drives to configure a home NAS (nothing critical, but still don't want pure garbage)The bad: These do not appear to be cleaned up in any way shape or form, just a used drive that is error free.In face, running CrystalDiskInfo on each drive, they are all between 52,613 and 52459 hours of use, how precise that they are all 6 years and 2 to 4 days of use. They are obviously data center dumps. Wish I had checked more of the lower star reviews and noticed, otherwise I would have just purchased 4 brand new drives.

I bought the drive to be used as an internal storage drive. It arrived way ahead of the estimated date provided by Amazon very well packaged, identically to any new hard drive I have bought in the past. I mounted it in my PC, connected it up, formatted it, and started tranasfering files to it. The read and write speeds under real usage are faster than a Seagate 8TB EXOS drive that I have mounted in the same system. Using Hard Drive Sentinel, it has a lot of hours on it, but very few power cycles, and shows 100% health. I imagine it was used in a NAS type situation or possibly in a Crypto rig. However it was used, it is well worth the price I paid and would definitely buy another if I needed one. It is quiet and it runs at normal temps. The seller reached out to me to make sure everything was satisfactory and reminded me that if there were any issues within the warranty period that I should contact them directly and they would make sure the issue was resolved. Just a genuine, "we're here if you need us", contact after receiving the drive.

Quiet and seemingly solid drives. Mounting screw holes on the bottom of the drive did not match removable cage drawer holes in my Fractal Design enclosure, although the Toshiba 3GB drives from 2012-13 that were replaced matched exactly. Maybe the spec has changed or enterprise drives are different, but it's something that might affect if you mount drives from the bottom rather than the sides.

This drive was used in a data center probably, 24 times started 50,000 hours ran. I like the rebuild, and refill of helium in it's case. I wonder if 2 of these would get too hot in my Asustor Drivestor 2 AS1102T NAS that right now has two 4TB Ironwolfs in there at 5900 rpm. It's a 2 bay, It has a good controllable fan. I'll look to see. This one I used to backup the NAS. I want two more of these 8TB to stuff in there.Edit: just bought another one, I previously bought two for RAID 1 on my NAS, the one I bought today is just a backup drive if one of my other two 8TB drives fail.Edit: Just bought my fourth one, two have been running 24/7 in my server for the past year, not a single hiccup or problem. I have it set to test them for bad blocks once a month and a SMART scan weekly, they have never had a problem. Excellent drives I run a newer server now with these, an Asustor AS6702T, so much better than the one I started with these on that weak Asustor AS1102T. I love these drives in my great server, then newer one that I just made the last payment on today, 12 payments over the year's time. Get this drive, you won't regret it.

These drives arrived in good packaging.Tests run:- SMART short test- SMART extended test- badblocks- custom read/write sampling script testing I/O averagesSMART results showed the drives ranging from 5.9 years power on to 6.5 years.One drive did not pass the SMART extended test, due to an issue with low helium.The warranty process was very easy, and support was willing to be flexible and work with my schedule. The replacement drive arrived a few days later, and passed all tests.Both drives are now live, and seem to be operating well around 29 degrees and reasonable I/O against random automated small nfs read/write transactions as well as large SMB file transfers. They are occasionally audible, which is to be expected.Used drives are always going to have a few bad outliers, stuff happens in transit, etc. What matters more with used drives is that the company was willing to stand behind their warranty. Very happy with customer service and would place future orders!

I honestly don't really have anything bad to say about these drives. I ordered and received 30 of these drives with an average power on time of just over two years. That is perfectly acceptable to me. Since they were used, I expected them to look used, so nothing to report there. I can say they were clean, every drive sealed in a anti static bag, and more than adequate protection for shipping.The only negative I can give these drives is HGST/WD 8TB and above drives have higher than normal vibration. I know they are built to withstand the vibration, it's just something that I look at as a area of quality they could improve upon. And this goes for my brand new retail 8TB WD Red's as well. As an example, my 12TB Seagate EXOS drives are smooth as silk. I'm honestly not a fan of Seagate, so that should mean something coming from me.As to the seller goHardDrive, I have been buying drives from them for years. Unfortunately I have had to use their warranty on some of my 2TB WD RE4's a couple years ago. I have to be honest, it was 10 times easier than dealing with WD directly. I simply emailed them with my original order number, and the serial number of the failed drive. A couple hours later I received a response with a RMA# and a pre paid shipping label. I sent the drive off and literally had my replacement drive the same week. Anyone who has ever had to deal directly with a manufacturer knows it is never that easy, takes longer, and is rarely free return shipping. So as far as the warranty or the service after the sale, it doesn't get any better than goHardDrive.

I have bought 3 of these renewed hard drives. All of them arrived on time and in good good condition. I will be the first to tell you that I am a bit skeptical when it comes to used, renewed or refurbished hard drives. But I took a chance on these HGST hard drives, mainly for the price and the higher RPMs. One of the hard drives was on for 1484 days, one was 2032 days and the last one was 2382 days. All are quiet and spin fast at 7200RPM. I used these drvies as backups. I would buy them again when I need more and if they are available.

Estan bien los discos duros pero al menos el que me mandaron tenia mas de 35000 horas de uso, se me hace demasiado

高耐久のヘリウムハードドライブを使ってみたかったので(リファービッシュ品)ですが安いので試しに購入。配送予定日いっぱいの10日間掛かって、宛名が「Yuan Chong」・・・全く違う名前になっていたので、配達から持ち帰りで営業所止まりになってました。電話で確認し営業所まで取りに行きました。動作確認：使用時間が47294時間と5年物、電源投入回数17回異音無し、状態はDiskInfoとDiskMarkを見て下さい。個人的には思ったより遅い？　東芝MN05ACA800の方が読み書きが早いロットもあるので、新品のそっちの方が良いかも？7200RPMのHDDは、HGSTの方が少し温度が高いです。裸でUSB外付けでコピーしてたら50℃まで上がってビックリしたが、ケース内でファン付き環境だと47℃ほど、アイドリングで43℃で、東芝MN05ACA800と差ほど変わらなかった。外気温が29℃の時なのでこんな物かなと思うが、7200RPMのHDDはどのみち温度高めなので、夏場は無風で長時間は厳しそうです。あと、いくら高耐久だとしても、駆動時間5年物なので、もう少し安い方が嬉しいかな、初期不良以外の保証もよく分からないし・・リファービッシュ品（言ってみれば中古）な訳なので、細かく気にする人は手を出さない方が良いとは思う。梱包も商品写真の小箱？を、緩衝材無しの袋に入れて送ってきたので、ぱっと見精密機器に見えないので、配達業者がどこまで丁寧に扱えるか心配ではある。※初期不良は無かったですが宛名ミスも気になった・・マーケットプレイスだとしても、Amazon購入なのに全く違う名前とか何故起こるのが不思議。もし壊れれば追ってレビューします。

I needed some additional storage and decided to take a gamble on this HGST Ultrastar He8- HUH728080ALE604 drive and so far so good.The drive is sold my Evrymm, and shipped from the USA. The drive I received was manufactured 7 years ago, and has been powered on for over 5 years (48000 hours showing in SMART stats). All of the drive's stats look good including the Helium Level indicated. The drive was well packed and not reporting any bad sectors or any other issues. I completed a full format (which took about 30 hours) to put the drive through its paces and check for any bad blocks and SMART stats still looked good after the full format was completed.This drive comes with a 90 day warranty from Amazon, and I was able to confirm with Evrymm's customer service that they will cover the drive for 3 years as stated in the listing for this product.I am very happy with this purchase so far.
