DELL/Seagate Constellation ES ST4000NM0033 4TB 7200RPM 128MB Cache SATA 6.0Gb/s 3.5" Internal Enterprise Hard Drive - 5 Year Warranty (Renewed)

Excellent deal and also passed onto friend who also ordered one - I stalked in my main system and a happy customer .

All almost perfect except one disk. Long SMART test passed for all 3 disks. RAID 5 was successful, though one disk started to be above a threshold for couple rates and require attention or replacement. RAID is heavy task and tear disks, though for server grade shouldn't go above treshold at least for first array proccessing... I using RAID, it was a trade off and planned for refurbished disks from start. fail will not make a big problem, though it could be needed to have spare disk too soon.

I purchased two of these in Feb 2021 with 5 year warranty. One of them failed in Jan 2024. Amazon contacted reseller regarding my issue and advised me reseller would contact me within 48 hours. Reseller never reached out to me. Apparently the reseller has no intention of honoring warranty by replacing or refunding.

I work in the Post Audio Film & TV industry and like how well and fast this 4G Hard Drive keeps up with Pro Tools 12

Seems like a great value. It arrived in a sealed bag supported on the ends for shock protection and appeared brand new. Windows needed to initialize the disk, and format partitions and has run flawlessly since then (24 hours of hard core data transfer).

I ordered 2 of these, an HP version came in. I checked power-on time and it was zero hours. Relatively fast and quiet, enterprise grade and 5 year warranty.

It arrived dead, would not accept a format. Honestly, not worth the trouble to return. Just stay away from renewed drives. It might have looked fine at the refurbisher, but after shipping it may just have died. Remember there is a reason these are being pulled out of production environments!

Okay so 2 of the 4 drives I purchased have failed in a 1 week timeframe so removing 3 stars for the failure of these. I still believe if you get good drives this is a tremendous value and the company does ship them quickly when they are in stock. In my case I was unlucky and received 2 that failed. One failed my NAS integrity tests and reported "The drive has failed" and the second drive reported hundreds of "I/O failure" and "An I/O failure occurred on the drive". I purchased two of the Toshiba N300 drives that are on the Synology compatibility list (although the other 2 Constellation drives seem to be running fine in my unit so far.)Original review below...All hard drives are used once you plug them in. Will a refurbished unit die faster than a new one? Who knows - but at half the cost of new disks I can populate my NAS with good quality 16TB (12TB usable) storage and replace a failed drive if needed without any data loss. These drives came in sealed in antistatic bags. They were clearly cleaned, tested, and worked as designed. I performed a long destructive test prior to placing them into production and they were amazingly free of bad sectors. They came very professionally and carefully packaged to avoid shipping damage. Best of all they arrived extremely fast - much quicker than promised. It's great dealing with a vendor that under promises and over delivers! I just purchased 2 more - thanks for the great service.
