About this deal

I had a slightly different experience from what is expressed here, though I’m not casting any doubt on the validity of the information. I have a Nimbustor 4, populated with 4x8TB, for 24TB of storage.

BTW, also worth noting, the weight of the NAS might become significantly higher when you are using more drives (noticeable after 8x drives IMHO)

I hope you will be able and willing to answer my question. I have a DS218+ with 2 8TB seagate iron wolf harddrives. I want to have an upgrade so I’m buying a DS420+ nas and 2 18TB seagate iron wolf harddrives. My plan is to replace my 2bay synology to the new 4bay synology and I want to know if I can just put the 2 8TB drives into the new synology and then also add the 2 new 18TB drive in bay 3 and 4.. Bigger disks means less options for redundancy as you have less individual disks, less theoretical throughput and often higher cost because even though the cost per GB drops the amount of GB’s per disk is significantly higher. I assume the home/office/prosumer market is all-but free-riding on their megala-enterprise/corporate market success.

More disks is more power draw, more vibrations more heat production and more physical space used. With the added redundancy comes less capacity as the redundancy means disks are there just to cover the situation where one or potentially more disks fail protecting you from data loss in those cases.When I originally set it up, it had two drives in it. It was kind of noisy but no more than I expected. When I added a third drive, the noise and amount of disc access was much greater than it had been. This change in policy is significant for users needing specific storage solutions or those accustomed to a broader choice of drives. It contrasts with other NAS brands, which continue to support a variety of third-party drives, including the latest high-capacity models. When choosing a NAS hard drive in 2023/2024, it’s crucial to consider not just the drive’s specifications but also its compatibility with your NAS system. This ensures that you can take full advantage of the NAS’s features and avoid potential compatibility issues. Thks again Robbie & it’s nice to see synology supporting the home/office/prosumer market a little more. However let me remember us ; Business-wide you should replace your HD’s every 3 years (5 years, max) but for the average user at home, you replace when really needed. (or after 10 years?) Before selecting the right NAS hard drive, it’s essential to grasp some key terms in the data storage industry. This knowledge ensures that the drive you choose meets your requirements to the highest standard. Here are some crucial terms you need to know, updated for 2023/2024, to decode the marketing jargon and understand the strengths and weaknesses of each drive:

In recent years we have seen Seagate reshuffle their range of available capacities to align the capacities from 1-12TB to arrive in the standard Ironwolf range and Capacities of up to 18TB and 22TB to arrive on the PRO series (likely due to those larger capacity options requiring the more enterprise hardware as standard and making a non-PRO version impossible without purposely nerf’ing the lesser drives intentionally. There is crossover in 4-12TB models in between, however, the distinction in RPM, cache, build design and TBW rating is wide enough to justify this. The noise level of the Ironwolf HDD series in PRO is noticeable higher, but given these are designed for larger arrays, this noise increase will be less noticeable over the ambient noise of the whole system generally.

Seamless integration with your mobile devices

The NAS itself represented the best box I could justify. Being four bay, it also gave me the opportunity to spread my expenses over a longer period.

The drives themselves are fantastically dull in appearance of course, as one might expect from the enterprise tier and also feature quite an aggressive spin up noise. However, in much larger scale environments, you will almost certainly not hear the drive media over the ambient system fan noise. Overall still an oldie but a goodie! Unlike the best external hard drive or the best portable SSD, NAS devices offer a unique advantage: internet connectivity. This allows you to access your stored files remotely, ensuring you have the convenience to retrieve data from anywhere in the world. SATA – Despite it’s age, SATA still remains the most popular connection of HDDs in 2023/2024 (despite the rise of M.2 NVMe SSD use in NAS). SATA allows up to 6 Gigabits per second throughput. However, mechanical HDDs rarely exceeded 280MB/s. By 2023/2024, while SATA remains prevalent, advancements in connections like SAS, NVMe, and U.2, particularly in SSDs, have become more significant in enterprise settings. More means higher throughput can be achieved and higher levels of redundancy can be gained making the setup more resilient when it comes to disk failure. Saturation – This term refers to the amount of data flowing through an interface/bandwidth. For instance, a SATA HDD might allow up to 600MB/s, but most NAS HDDs achieve around 180-280MB/s due to their mechanical design. Therefore, the saturation for a single drive is lower, at 180/280MB/s.Certainly one of the most expensive NAS HDDs out there, but provides a very good level of storage, performance, durability and overall is a very dependable drive for SMB users (Small/Medium Business) that want a drive they can rely on. The differences between the Synology HAT3300, HAT5300/HAS5300 are pretty much exactly as you would find if you compared WD Red and Seagate IronWolf versus that of Seagate Exos and WD Ultrastar. Indeed, I am a little surprised that Synology has not introduced a middle ground in the form of a pro series drive, but perhaps this is something that will roll out later down the line. Nevertheless, this results in quite a void of performance, durability, and scale between these two ranges when compared to long-term established server hard drive ranges from these other companies filling the gaps of capacity and pro middle ground choices. It should be immediately highlighted that regardless of which Synology hard drive you opt for, you still benefit from firmware updates being actionable from within the Synology DSM software, easier and more streamlined warranty support, and firmware optimization that is specifically tailored towards Synology hardware deployment. We have discussed this at length previously when discussing the Synology enterprise hard drives and SSDs, and although you pay a premium for Synology’s own branded drives when compared to third-party alternatives that people have been using for decades, there are nonetheless merits in using drives specifically geared towards your NAS system rather than requiring a slightly broader design that suits more diverse servers. Here is how the Synology enterprise SATA, enterprise SAS, and mid-range plus hard drives differ in their specifications: I understand that they dont add 20TB HDDs on the list if they dont have have their own supported HDDs go up to 20TB. In a company meeting someone might ask “could we go for 20? a simple NO is better than “well we could, but it’s not 100% supported” and then the whole mess would come up… in the end the boss would say “this is to complicated… lets go with another comapny” (welcome to corporate world). In the end it is mainly about certificates that you can hold up and say “this paper says it’s not my fault”. As an Arch Linux user, I was torn between buying an expensive (new) tiny RAID machine with 4 x new HDD’s or using an old (but free) monstrous 12 bay Supermicro server with 12 (free) smaller HDD’s. So.. can I just take the 2 older 8TB drives (in SHR) out of my 2bay synology and put them together with the 2 18Tb drives into the new 4 bay synology without losing my data or without having to figure out a way to transfer the data off the drives first.. I do not have the external drive space to temporary store 8Tb worth of data. I don’t really care all that much about any settings from my old nas, all I want is to keep all my own data safe when transferring to the new nas.
