Seagate Exos X18 16TB Enterprise HDD - CMR 3.5 Inch Hyperscale SATA 6Gb/s, 7200 RPM, 512e and 4Kn FastFormat, Low Latency with Enhanced Caching (Renewed)

These industrial-grade, non-shingled, refurbished hard disks give you about twice the storage for same price as "red label" consumer drive. I've bought 8 of them so far with no problems. The head seeking is a bit noisy, and this noise can be passed-on to the docking bay (if you use the disk this way). I stuffed a Q-Tip into the mount which prevents it from passing the vibration, and that helped a lot! Needless to say, it's very fast.

I've bought a batch of 5 enterprise grade hard drives. One of them was detected, and I was able to initialize and format the disk after a couple of unsuccessful attempts. However, the drive started its life with a long screeching sound, which is a clear indication of physical damage. The other 4 drives weren't even detected, and they each consistently emitted every sound one would expect from a dead hard disk drive during the spin-up phase. Normally a "refurbished" HDD simply means a returned HDD that is unboxed, since it's not possible to actually refurbish hard disk drives, and it's not possible to sell it as new either. These drives however, are clearly all end-of-life, dead units.

Perfect for my Synology 5 bay, I run 2 X16's for data and bought 2 of these X18's for surveillance. These drives have over 4600 hours of perfect runtime and will likely last a long time (my X16's have over 20 thousand hours on them! I ran these HARD for about a week with read, write, and smart tests to make 100% sure they are good drives, and they are! I wanted the best, so I bought the Exos line, these are enterprise class drives, an absolute workhorses of the data industry.

AVOID You are accepting a risk purchasing. These drives as they are refurbished but this one arrived completely dead on arrival. Hard drive clicked and wind as soon as I plugged it in. These probably go through absolutely zero quality assurance or checks. Luckily Amazon takes them back, but don’t waste your time. Spend the extra couple of dollars to get brand new drives.

Picked 1 up for the NAS. Packaging was great, wrapped in anti-static bag, then high-grade bubble-wrap followed by spacers within a box. Zero wiggle room in the packaging. Have started hearing the head after just under 500 hours, so will likely need to be replaced. Surprising considering the Exos reputation but this is a renewed and included no details on it's prior usage.

This drive was at 0 hours when I first powered it on. I didn't think to take a screenshot immediately. Thus far working perfectly. ( I have multiple other drives 12-16 TB I have bought renewed as well, all have been problem free). If anything changes I will update, but I do not anticipate any issues

I have been in the software industry for 45 years. I have purchased hundreds of hard drives in that time. I have never had one go bad in weeks, or even months. I purchased 3 of these refurbished drives. 1 went bad about 3 weeks later. It was within the return window. The 2nd went bad in the 4th month of use. 1 of the 3 is still working. I don't know what 'refurbished' means, but I would suggest that there really is something wrong with them, and that is why they are 'refurbished'. I recommend paying a few extra bucks, and getting the one that is new from the manufacturer.

These Seagate drives (at least the 16TB one that I bought) were sourced and originally sold in the Chinese market (not the U.S.). Because these aren't drives intended for the U.S. market, Seagate will NOT offer any warranty assistance. These drives essentially have no warranty at all! Should the drive fail (which is highly likely) outside the 90-day return window you'll be left without options. Amazon really needs to hold their resellers to higher standards. It's wrong to sell a refurbished product without any warranty whatsoever.

とても使い勝手が良く静音です。

正常に動作しています。ロジテックのHDDケースに入れて外付けドライブとして使用しています。 整備済み品はお買い得ですね。

再生品ということで不安はありましたが価格で選びました。使い始めて4か月経ちましたが 問題なく動作しています。

安価な価格で整備済み品を購入しましたが、非常に残念なことに、製品を接続した際にピープ音がなり、HDD自体が正常に動作しない状態でした。このような不具合があると、購入者としては非常に落胆しますし、整備済み品を購入する際に対する信頼感が揺らぎます。 整備済み品を選んだのは、予算を節約しながら高品質の製品を手に入れるためであり、整備済み品には信頼が置かれていました。しかし、この経験を通じて、整備済み品の品質については慎重に検討する必要があることを痛感しました。 これらの問題は、購入者としては避けたかったものであり、非常に悲しい結果となりました。今後は信頼性の高い販売者や整備済み品の品質について詳細に調査し、信頼性の高い製品を選ぶことが大切です。購入者としての経験から得られた教訓を活かし、今後の購入に活かしていきたいと思います。

しっかり稼働しております！お得でした！
