WD Red 2TB 3.5 Inch NAS Internal Hard Drive - 5400 RPM - WD20EFRX

Product Information

I’m thinking about getting a DS423+ (home media server) and by doing my research i found this great channel and learned a lot about the NAS world. BTW, also worth noting, the weight of the NAS might become significantly higher when you are using more drives (noticeable after 8x drives IMHO) You may feel SATA and SAS is mature tech and there should be no compatibility problems, but there are and there will be more. I’ve worked with (from memory) Adaptec, Areca, Raidcore, 3Ware and LSI. Sometimes the compatibility problems are blatantly obvious, but sometimes they are a creeping problem that takes time to develop, and they don’t get better with time. Sometimes a firmware upgrade of the drives or the controller can help, but there’s no guarantee that either is coming if you start out with incompatible hardware. Cache – This memory area on the NAS hard drive compiles and distributes data being processed by the disk. Larger capacity NAS hard drives typically have a larger cache, as do drives using Shingled Magnetic Recording (SMR), which requires more handling space due to its unique writing style.

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: 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. 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?) But more drives also means more power-use as you already indicated and also more heat. (more cooling might be needed)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. 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”.

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!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.

The Ultrastar series of hard drives will often be compared against the WD Red Pro range of NAS hard drives when considering populating a server. It is worth remembering that the Ultrastar series is designed for both a higher performance AND a much more enduring performance – i.e it can maintain that level, as well as switch between processes, for much longer. Indeed in testing, the Ultrastar even features a much higher Read and Write performance than pretty much any other drive that peaks as high as 280MB/s in our ATTO DiskBenchmark testing below with just a single HDD. Even the IOs (IOPS_ went as high as 19,000, which although low when compared with modern high-end SSDs, for a single HDD is really impressive).Personal use 20tb should be more than suffice. which is probably 4x5tb or 5×4 tb. 450-500 usd probably. All my photos from 2010 is only around 400gb jpg. and since current hdds are 4-5tb or so, yea I can manage to save more copies in more drives. 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.

Magnetic Recording – This refers to how data is stored on the platters. As of 2023/2024, there are several prevalent types: SMR (Shingled Magnetic Recording), PMR/CMR (Perpendicular/Conventional Magnetic Recording), EAMR (Energy Assisted Magnetic Recording), and HAMR (Heat Assisted Magnetic Recording). Each type has its pros and cons, but PMR/CMR remains the most popular for NAS hard drives. Alls I’m a-saying is; we should be more graceful for synology support to their home/office/prosumer market all-the-while still politely reminding/nagging them of our desires/dreads (aka catching more flies with honey whether than vinegar).The WD Elements external HDD comes in a variety of sizes from 1TB to 5TB and is an extremely affordable storage solution. It is compatible with PC, Mac, PS4, and Xbox and has both USB 3.0 and 2.0 ports. It measures a diminutive 4.35 inches long and 3.23 inches wide and won't take up much room on your desk, TV stand, or travel bag. 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.
