    • Excellent HDD Drive for Synology DS923+!
Review Image by Adalberto
Review Image by Adalberto
The seller was incredibly helpful and provided tracking information and was shipped the same day! Received this HDD the following day early morning and was very well packaged and arrived without any damages! I installed this HDD to my Synology DS923+, went through the process of formatting and creating a storage pool, as this was the first HDD to use on this new NAS. The Seagate Exos X22 20TB SATA 6Gb/s 7200RPM 3.5-inch Enterprise HDD - ST20000NM004E (Renewed) HDD Drive contained an available storage capacity of 18616GB or 18.616TB of available storage, according to the Storage Creation Wizard of Synology. I performed a S.M.A.R.T test, took about three days to complete and my Synology NAS didn't detect any issues with this drive. I performed a stress test and transferred significant large sized files/videos over to my NAS using this HDD, and it handled everything very well! This HDD can handle read/write speeds of 25GB large filed videos. I recommend transferring large files to your NAS by hardwiring it directly to your PC, instead of transferring over WiFI to get better transfer results. I will be adding large SSD cache NVMe M.2 drives to significantly increase read/write speeds on my NAS. Noise level on this HDD is not to loud, but you can definitely hear the click/clack sounds when there's activity on the HDD. It's not loud for me, as I store my NAS on my server cabinet of my home office. This is a great purchase and highly recommend it from this awesome seller! ... show more

    • So far so good
I am pretty paranoid about second-hand core computer parts (graphics cards, HDD, SDD, and CPUs). The fact that these refurbished units have a 2-year warranty on them helped ease my mind. I purchased 3 20TB drives. 1 of the drives made an unnerving clicking noise while idle. I sent that one back and quickly got a replacement. All 3 of my drives are healthy and shipped with less than 30 hours of run time on each drive. They now happily hum away in my NAS I am not sure what would constitute a noisy drive. I am used to the muted clunking noise of HDDs and have never ran enough at the same time, under load, for the noise they make to be offensive. The drives work well in my DS1522+ and I am having no problems with them. The drives now have 800 hours under their belt and are performing just fine. ... show more

    • Better than what I had expected
I bought this Seagate (Renewed) Exos X22 20TB disk with some trepidation because I did not know what to expect of a "Renewed" product. The disk that I received says "Recertified product" on it but for all I can tell it looks and works like brand new. I have been copying files to it for the last four days, nonstop, and probably have two or three more days to go. The copying is slow because the disk is hooked to my machine through a USB port as I have no additional internal slots available inside my computer. Monitoring the progress, I see no error messages in my dmesg (this is in Linux), which is reassuring. In short, I am very happy with this purchase and I hope everyone else buying a Renewed disk will have a positive experience like mine. ... show more

    • Not a good drive
I ordered this to replace another bad drive from Amazon. This one beeped, never showed up on the motherboard and not recognized by Windows 11 pro. I set it up by disconnecting another drive, nothing! Sent it back. Hopefully when I order a 4th drive I can get another one that works. 1 good Toshiba and a bad Seagate and HP. Really sucks to be me! ... show more

    • Good drive but not stated size
Well my new 22TB drive show as 20TB formated. Well this 22TB refurbished shows as 18TB. It was a good price and I already filled a good chunk before realizing this but otherwise has worked well.

    • Drive was DOA
Drive was DOA. I tested it in two different machines and with an external docker. Seller offered to replace, but I returned the unit for a refund and purchased a new one instead. New one from Seagate worked without any issue.

    • Tons of Storage, Reliable Shipper
After researching forever to find a good $/TB to upgrade my NAS, I finally settled on recertified drives and went with this seller (Serverpartdeals wouldn't ship to APO). Despite warnings on Reddit about recertified drives from Amazon, my experience with these have been so far solid. I bought 2x20TB Exos X22s Both drives were shipped in anti-static bags, and each drive was in a specially fitted extremely padded bubble wrap enclosure within a cardboard box. There was even more padding in the outer box, so I wasn't worried at all that they were damaged during international military shipment (notorious for being the roughest on USPS packages). Plugged both drives into my Unraid and they were detected no issue. Ran SMART tests on both and both were good to go. On the Exos front, there is a bit of noise on first boot, and if you are doing heavy writing/reading then they are a bit loud, but that's what you expect from this level of drive. Transferred 5TB+ of data to one of the drives without issue. Price was killer and product was solid, no reason to worry about them being recertified! ... show more
