Seagate IronWolf Pro, 4 TB, Enterprise NAS Internal HDD –CMR 3.5 Inch, SATA 6 Gb/s, 7,200 RPM, 256 MB Cache for RAID Network Attached Storage (ST4000NT001)

I am giving for stars mostly for the support I got from Amazon customer service regarding my order. I bought two 12TB drives on the 23rd nov during the sale period. I got them on the 15th Dec. I was traveling during that time, but when I got home, I installed them right away in my brand new NAS. Unfortunately only one worked without a problem. The other one was spinning but was not loading and reading nothing. I tried to put in intro a PC and also a 3.5 sata adapter and connected to a laptop. The same problem-it wasn't readable. Luckly amazon customer service undarstood the problem and gave me a refund. I bought a WD drives this time.

I attached this directly to my QNAP TR-004 DAS, it was ok from the start but after few weeks it starts showing some warning signs on my QNAP software. The problem is there's no way to fix it but to change the drive, but because i bought this online, there's no way to exchange this after few weeks of using. As a user of NAS/DAS, this is a big "no recommendation" for me.

two our four HDDs that I received had controller-level failure. I inserted them in my brand-new QNAP and I received I/O error. tried many solutions but the error is there and I had to return the two of them. maybe the reason is that it was shipped from US to UAE using DHL post. but anyhow, I faced a 50% failure

This was one of the drives I returned. I ordered 5 x 8TB drives. The 1st and 2nd came good, 3rd one has some bad sectors but it’s ok I accepted. The 4th one was simply not running. So I returned this item and ordered a 5th one to replace it, it also was defective. So: 3 out of 5 drives - I would normally give 3 stars, but I can’t because of the disappointment and waiting . So 2 stars because atleast the first 2 were perfect and the 3rd was just ok.

Velocissimo. Solo un po’ rumoroso.

So far so good. I sees a few complaints but mine have been working non stop since my purchase. Also the noise level is close to none. I spend most of my time in the same room as the product these are installed in and I don’t hear a peep. The storage capacity is more than I will need for a while. The price was very competitive for the market when I purchased. Will be sure to purchase more once these are filled up since the quality of these is so good.

Excellent

I bought 4 of these, 3 were working and 1 spoilt.. i almost returned it but found out i could send to Seagate for RMA to get a replacement.. so i did that as i bought it at a super price.. returning it would mean i'd have to buy another at a much higher price. Overall still happy since i can get a new one from Seagate as they have international warranty. Update 18May'25: i sent in the 12TB to Seagate for RMA, and they sent me a replacement 18TB.. how awesome is that.. :-)

Bom desempenho, silencioso
