Synology RS4826xs+ overview
The second XS+ model that has been released in APAC and announced today by Synology is another 2U NAS mimicking the RS3626xs+ in almost all elements while still pushing the bar just a bit higher.
The main thing to mention here is that so far, we have not had this model number before, so this represents a new member of the XS+ lineup. Here is the brand new RS4826xs+.
Arriving in a standard 2U chassis, the new RS4826xs+ on the outside is identical to any other model, even outside the RS segment. It is always the internals that make the difference anyway, so let's see what this new NAS has under the hood.
High-speed performance: Over 135,000 4K random write IOPS and 6,200/3,700 MB/s sequential read/write performance supports demanding workloads
As already mentioned in the RS3626xs+ overview article, all new XS+ models are sticking with the Intel Xeon CPU, but this time around, Synology decided to use the D-1739 CPU model instead of the D-1726 in the RS3626xs+.
What that means is that we have an additional two CPU cores and four more threads, a total of 8-cores (16-threads), but also more TDP (83W to be exact), and more RAM to spare. Yes, unlike the limitation of 48GB for the RS3626xs+, the RS4826xs+ comes with 16GB of RAM and has a hard deck of 96GB across six (6) slots. It is obvious that the motherboard in question is identical in both models, and the RAM limitation is a Synology-driven one and not a limitation of the MBO or the CPU when comparing the two models.
So, what exactly is this model replacing, if anything? So far, we have had the 36xx segment, as well as an RS4021xs+. The latter was the 96GB RAM model, but in a 3U chassis and 16 drives to boot. Its maximum capacity, as stated by its name, was 40 drives with two additional 12-bay expansion units.
Scalable capacity: Simple expansion to up to 48 bays is available as needed with three Synology RX1225RP expansion units
Now it becomes a bit clearer why the new RS3626xs+, while still having overall better hardware than its direct predecessor, had some compromises (lack of RAM, to name a few). It was to make room for this new "hybrid" model.
With the RS4826xs+, Synology has still offered a successor to the RS4021xs+, essentially, but in a 2U chassis with better hardware upgrades as well. The only downside is the lack of four initial bays (2U vs 3U), but the overall number of supported drives has increased to a total of 48 drives.
With the new lineup of X26 2U models, customers will be able to get more for less (smaller 2U device) while also not paying a premium should they want a decent enough 2U all-around NAS such as the RS3626xs+.
So, to sum up, Synology will probably depricate the RS4021xs+ and replace it with this RS4826xs+, and in case customers want a 3U 16-bay model, they can opt for yet another new model, the RS6426xs+ (more on that one in a dedicated overview).
The overview of this NAS is not much different than the RS3626xs+. Based on the same architecture and a slight difference in CPU, the main upgrade is the increased RAM, as well as support for three (3) RX1225RP expansion units to accommodate all 48 drives.
Being almost identical, the PCIe 4.0 support is here as well, with two Gen4 x8 slots (x8 link), dual 10GbE, two USB 3.2 Gen 1, and a single 1GbE management port replacing the old console one. Of course, the redundant power supply is here as well.

What the RS3626xs+ lacks, this NAS can offer. The mentioned lack of 1PB single-volume support is here (as it was on the RS3621xs+ due to RAM capacity), so anyone looking to upgrade from the X21 model to a new 2U device, this would be it.
The RS4826xs+ can be configured as part of a hot or cold storage tier depending on deployment requirements

It is also interesting to note that this model can be upgraded with 16GB stick modules as opposed to 8GB ones in the RS3626xs+, and with the current pricing, going beyond the standard 16GB that the RS4826xs+ comes with might be a decision that many will think about before committing.
Looking at the optional accessories above, the disk compatibility is as expected, enterprise one. Once again, all XS+ models need to use only Synology-branded drives under the HCL 4.0 policy.
This especially applies to the optional cache scenario. Using either SATA or M.2 SSD drives, the requirement is that those be Synology SAT5200 series or the SNV3400/5400 ones.
Apart from this, again, standard 2U chassis, 14.5 kg, with a 5-year Synology warranty. Global launch is May 13th, like the RS3626xs+, with a currently unknown price tag.
