It goes through the compatibility and installation points worth checking before you buy, and the uses it is not suited for. ## Overview The Synology RackStation RS822+ — 4-Bay Rackmount NAS Kit is a 1U, 4-bay NAS that fits a standard 19-inch rack. In short, it is a strong choice for small offices and home labs that already have a rack and want DSM snapshots and backup tools in a compact unit. It is a poor fit for homes without a rack, or for anyone who mainly needs video transcoding. It runs an AMD Ryzen V1500 (4 cores, 2.2GHz) with 2GB of DDR4 ECC memory, which can be expanded to 32GB. It is a diskless kit, so your budget has to include the drives. It runs Synology DiskStation Manager (DSM), which lets you manage file sharing, snapshots, and PC and server backups from a browser. On Amazon. co. ## Compatibility Guide ### Rack and Space It measures 44 x 435 x 492 mm (1U) and weighs about 5.1 kg. Height is rarely a problem at 1U. Depth is what people miss: once you allow for cables at the back, you need extra room. It may not fit shallow wall-mount racks or small network racks. Before buying, check which mounting hardware is included and which is sold separately, and whether it matches your rack posts. ### Drives It takes 3.5-inch and 2.5-inch SATA HDDs and SSDs, and the drives are hot-swappable. Maximum internal capacity is listed as 72TB (18TB x4). Note that recent Synology business models are designed around Synology's own compatibility list. Drives that are not on the list may still work, but DSM can show warnings and support may be limited. For business use, drives on the list, such as Synology's HAT3310 series, are the safe choice. ### Memory It ships with 2GB of DDR4 ECC and supports up to 32GB. It expects ECC memory, so don't plan on reusing non-ECC desktop RAM. Modules from Synology's compatibility list help you avoid support problems. ### Expansion Slot and Network One PCIe Gen3 x8 slot accepts a 10GbE network card or an adapter card for M.2 NVMe SSD caching. Because there is only one slot, you would need a combo card on the compatibility list to have both 10GbE and NVMe cache. The article data lists two 1GbE RJ-45 ports. Some listings and documents give a different port count, so check the official spec sheet if you are planning the network around it. There are two USB 3.2 Gen 1 ports, and a UPS is usually connected over USB. ### Expansion Unit The optional RX418 expansion unit adds bays beyond the four in the chassis. The article data says up to 12 bays, but the number of units you can attach and the maximum drive count depend on the model. If you are counting on expanding later, confirm it on the official spec sheet. ### File System and RAID Choose Btrfs if you want snapshots. | Layout (4 x 12TB example) | Approx. usable | Drive failures tolerated | |---|---|---| | RAID 5 / SHR-1 | ~36TB | 1 | | RAID 6 / SHR-2 | ~24TB | 2 | | RAID 10 | ~24TB | 1 (2 if the right pair fails) | | RAID 0 | ~48TB | None | These are rough raw figures, and DSM will report less usable space. With four bays and business data, the first decision is whether you value the safety of RAID 6/SHR-2 or the extra space of RAID 5/SHR-1. ## Product Info The Synology RackStation RS822+ was released in 2022. | Item | Value | |---|---| | CPU | AMD Ryzen V1500 4-core 2.2GHz | | Memory | 2GB DDR4 ECC (up to 32GB) | | Drive bays | 4x 3.5/2.5-inch SATA HDD/SSD | | Max internal capacity | 72TB (18TB x4) | | Network | 2x 1GbE RJ-45 | | USB | 2x USB 3.2 Gen 1 | | Expansion slot | 1x PCIe Gen3 x8 | | Dimensions | 44 x 435 x 492 mm (1U) | | Weight | Approx. 5.1 kg | | Warranty | 3 years | Amazon. co. Business hardware prices move with stock and exchange rates and change during sales, so check the product page for the current price. That price is for the chassis only. Four drives, any extra memory, a 10GbE card, and rack mounting hardware cost extra. The warranty is 3 years. In business use, the unit is unavailable while it is being repaired, even under warranty, so keep a separate backup destination. ## Compared With Desktop Models Among Synology's 4-bay NAS units, desktop and rackmount models suit clearly different settings. | Aspect | RS822+ (1U rack) | 4-bay desktop | |---|---|---| | Placement | Requires a 19-inch rack | Shelf or desk | | Noise | Small fans tend to be louder | Usually easier to keep quiet | | Cabling | Shares a rack with the switch and UPS | Each device placed separately | | Best place | Server room, office with a rack | Living space, small office | Without a rack, a desktop 4-bay unit such as the DS923+ or DS425+ is easier to place and usually quieter. If your network gear already lives in a rack, the RS822+ keeps cabling and power in one place. If you need eight or more bays from the start, a larger desktop unit such as the DS1819+ is simpler than adding expansion units later. ## Setup Steps 1. Check rack depth, free rack units, and power outlet location 2. Pick drives from the compatibility list and decide on RAID layout and capacity 3. Mount the drives in their trays, insert them, and secure the unit in the rack 4. Connect to the LAN, install DSM from a browser, and create a storage pool 5. Set up shared folders, user permissions, and snapshot schedules 6. Connect the UPS over USB and set up safe shutdown for power outages UPS integration is often put off. But a sudden power cut is a real risk to a RAID array, so set it up on day one. ## Best Use Cases - **IT staff at small businesses that run a rack**: It works well as a file server or backup target sitting in the same rack as the switch and UPS. DSM snapshots make it easier to restore files that were deleted by mistake or encrypted by ransomware. - **Home lab users with a rack**: The PCIe slot allows 10GbE or NVMe cache, so it can grow into storage for virtualization or a backup target. ECC memory support helps with long-term data storage. - **Offices that want backups in one place**: DSM's Active Backup for Business can collect backups of Windows, macOS, Linux, and virtual machines on one box. ## Before You Buy - **Without a rack, there is little reason to choose it**: A 1U unit only pays off inside a rack. On a shelf or the floor, cooling and noise get worse, not better. - **1U fan noise**: A 1U chassis is cooled by small fans, so it tends to be louder than desktop models. It is not suited to living rooms, bedrooms, or sitting next to a home-office desk. - **Weak at video transcoding**: The Ryzen V1500 has no integrated graphics, so don't expect hardware 4K transcoding in Plex or similar apps. If media serving is your main goal, look at a model with an integrated GPU. - **1GbE limits**: The standard network ports are 1GbE, which works out to a little over 100MB/s per link. Link aggregation does not speed up a single transfer to one PC. If you move large video files often, budget for a 10GbE card and a matching switch. - **No redundant power**: This model has a single power supply. If your work requires redundant power, consider an RP+ model instead. - **2GB of RAM is tight**: It is fine for file sharing, but plan to add memory if you run several packages, virtualization, or caching. - **Drive compatibility list**: As noted above, drives not on the list may trigger warnings or limit support. Check the list before reusing drives you already own. - **RAID is not a backup**: RAID protects against drive failure, not against accidental deletion, ransomware, or the whole unit failing. Keep a copy on another NAS or in the cloud. - **Check the listing carefully**: The collected store data had mismatches; for example, the overseas price field pointed to a Japanese Amazon page. Port count and maximum bay count also differ between sources. Confirm from the product photo and title that the model is the RS822+, and check specs in Synology's official documents. ## FAQ **Q. Are drives included? ** A. No. It is a diskless kit, so you buy 3.5-inch or 2.5-inch SATA drives separately. **Q. Is it OK for home use? ** A. It works, but it is awkward without a rack, and the 1U fans are noticeable. A desktop 4-bay model is easier at home. **Q. Can it do 10GbE? ** A. It ships with 1GbE, but you can add a compatible 10GbE card in the PCIe Gen3 x8 slot. Check which cards are supported on the compatibility list. **Q. How much memory can it take? ** A. Up to 32GB of DDR4 ECC. **Q. What if four bays are not enough? ** A. You can add the optional RX418 expansion unit. Check the official spec sheet for how many units it supports. ### Product Disclosure (Amazon) - Manufacturer: Synology - Seller: Amazon US - Fulfilled by: Amazon US - ASIN: B0B4DGP86W - Note: This article covers a manufacturer-made product based on Amazon listing details.
