I received two 18TB disks yesterday and installed them with RAID 1 on an old TS-230 NAS. Everything worked flawlessly. Surely, if someone wants absolute silence in their space, it will be a problem, but for me, it's not. However, this is not a problem specific to this disk, it is a general problem with mechanical disks.
I will come back regarding the reliability of the disks in the next period.
I have had it for about 3 months and I am very satisfied.
I am using it with the "Icy Box Docking Station IB-1121-U3" (Code skroutz 40902467) and everything runs smoothly.
If something goes wrong, I will come back with an update.
The best value for money at the moment for high-capacity drives. I have been using them for a few months in my NAS (TrueNAS SCALE with ZFS) and they have satisfactory throughput, low noise, and do not raise temperatures. Will update in 2-3 years.
Excellent value for money if you want a very high capacity. 8 were purchased and installed in a NAS. So far, everything is good.
It has been working flawlessly for a few days now on a QNAP TS-230 NAS, along with an additional WD Blue 4TB and an additional WD Green 4TB in an external enclosure connected as Hybrid Backup. The impressions so far are very positive
I have two X18 18TB drives as single drives, for over 18 months. Their operation is silent, their temperatures are low, consistently staying at 22-31°C.
They have a high but stable (very important) Transfer Rate: 195-245MB/s. Average Write Speed: 215MB/s. An exceptional disk, with better performance than the X16 series.
P.S. Measured in Raid0 in Sequential Read: 430-440MB/s
The spin-up is not audible at all and they only make a muffled noise during recording/reading, which is not bothersome.
Two disks were purchased (2X18TB for RAID 1 connection) for use in an office file server, which came in OEM version (white label). No noise issues that you will read here and there. With the chassis open, only the heads can be heard during startup. A slight "whirring" sound every now and then. With the chassis closed, nothing special (in a space under the desk - not next to me). We are talking about datacenter disks where noise is not desired. Our SSDs have probably spoiled us. However, when someone needs large storage space at a low price, magnetic disks are the way to go. They are chosen for reliability and longevity - that's what matters. Unfortunately, disks, from any manufacturer, usually come in their simple antistatic bag with a little bubble wrap around them. This is where the care of the seller, luck, and good wishes come into play for everything to go well. I hope I don't need to come back for an update on these comments.
For the NAS Synology that I installed, it is excellent. It is noisy since I installed 2, but with a temperature of 38 degrees, it is excellent.
I bought 2 and they work in RAID1 as part of my 3-2-1 data backup.
They are currently about 20% full.
The noise is somewhat subjective.
The model is noisy compared to a regular PC disk BUT... I would say that in the enterprise category it belongs to, it is one of the quietest. The spin-up is not heard at all and they only make a muffled noise during read/write.
They have been installed in a Dell R720 and so far they are delivering on their promises in terms of speed and temperatures. If any issues arise over time, I will update my evaluation.
So far, they are value for money with one of the lowest € per GB ratios.
If you don't know exactly what you are buying, choose another disk.
UPDATE: After a year of daily use (almost 24/7) and about 70% full, they continue to work flawlessly like the first day. If nothing better comes out soon, I will buy the same ones again.
Stay away from Seagate. It broke down in 2 years with minimal use. Get another company unless you want them for short-term use because they have low prices (and low reliability)
I bought 3 for DS920+. I have been using them for about 3 months and they work flawlessly 24/7 (read/write).
4 stars instead of 5 because they do make a LOT of noise (but it's understandable, they are meant for datacenter use and not for home NAS).
If any issues arise, I will update.
Very good and silent disk, something I definitely wanted. It has never gone above 46°C (measured with Hard Disk Sentinel) in the well-ventilated full tower case I have. It is quite fast for a SATAIII mechanical drive, but I haven't gone through the process of measurements and comparisons because I want it for backup purposes and not for everyday use
It was purchased for the QNap TS-230 NAS as it is compatible with supported hard drives.
The setup was not completed with a hard drive because it had a Read and Write Error, obviously DOA.
Seatools returned an RMA code.
An RMA return request was submitted to the store.
update:
- 27.12.21 delivered for inspection. Waiting...
- 07.01.22 The hard drive was replaced. Although I bought it to install it in the NAS, I will no longer take the risk, it will be tested thoroughly on the PC and then installed in the NAS.
I am upgrading the rating to 2 stars because it is functioning.
It passed the SEAGATE tests and seems to be quite fast and relatively quiet.
- 31.03.22 I am upgrading the rating to 4 stars. I am satisfied with its performance on the PC.
Verified purchase from GoldenByte
For now, it works flawlessly 24/7 for hourly backup of my server.
