Synology DS620slim External HDD/SSD Overview

Built to blend into modern workplaces or apartments, the DiskStation DS620slim 6-Bay NAS Enclosure from Synology is an all-around file management solution that fulfills professionals' needs of advanced data protection and high-quality media streaming. It supports near-instantaneous snapshot technology and real-time dual-channel H.264/H.265 4K video transcoding and is equipped with six 2.5" SATA HDD/SSD drive bays that support RAID 0, 1, 5, 6, 10, Basic, and Synology Hybrid RAID. Each RAID mode provides performance gains, data redundancy, or a combination of both. For those who do not need the benefits of a RAID, JBOD is also available.

The DS620slim runs on Synology DiskStation Manager (DSM) OS, which is a browser-based operating system which helps to simplify managing your Synology NAS. Its CPU is a 2.0 GHz Intel Celeron J3355 Dual-Core and its 2GB of DDR3L RAM allows frequently-used files and applications to be quickly accessed. The NAS is capable of achieving sequential read speeds of up to 226 MB/s and write speeds of up to 198 MB/s. Also featured are two USB 3.0/3.1 Gen 1 Type-A ports which allows it to be connected to your Windows or Mac system, and network connectivity is achieved via the dual integrated Gigabit Ethernet ports that support failover and link aggregation, while also allowing your stored data to be shared with users throughout the network. Data may also be made remotely available through the free iOS and Android applications.

The DS620slim is engineered to be energy efficient. Not only does it offer an 80 x 80mm fan to help keep the system running cool at all times, its noise dampening design of 20.5 dBA makes for quiet operations. The server supports numerous scheduled power on / off cycles and hard drive hibernation to further minimize power consumption and operation expenses.

The DiskStation DS620slim 6-Bay NAS Enclosure operates on 100-240 VAC at 50/60 Hz and includes a 250W AC power adapter, a power cable, and two RJ45 LAN cables. It is protected by a limited 2-year warranty.

can you use this with SATA SSDs? Is it fast enough to do 4k editing? any reason not to use SSDs in a NAS?
Asked by: Jaskanwar
It can be used with 2.5" SSDs. Per the Compatibility chart on the Synology website, there are Consumer, Business, NAS, and Enterprise class SSDs that are compatible with this unit. Synology recommends using the NAS or Enterprise-class SSDs, particularly if you expect heavy write action on the unit (SSD life is limited by the number of writes). This unit can do 4K-to-720 transcoding, but I do not know about editing. As far as I know there is no reason not to use SSDs in an NAS. The NAS has a 2 year warranty, and your SSDs may outlive the NAS. That is the only downside, as far as I can tell.

How/Why is Max ram listed as 6GB and unit has two dimms capacity. Why not 8GB RAM?
Asked by: William
Unfortunately we do not have information as to why the max supported memory of the Synology DiskStation DS620slim 6-Bay NAS Enclosure is 6GB instead of 8GB. This is just the hardware limitation of the enclosure.

What is max HDD capacity per drive bay?

What is max HDD capacity per drive bay?
Asked by: Christopher
The DS620slim only takes 2.5" drives drives up to 15mm high (twice as high as most slim notebook 2.5" drives), not 3.5" up to 1" high (like typical desktop or NAS hard drives) drives. E.g., a 22TB 3.5" will not fit. Same with other, popular 20TB, 18TB, 14TB and 8TB drive sizes in 3.5". Synology has tested the following capacities in 2.5" form factors. NAND SSD (max capacities of model-series): - Micron 5300 PRO (7.68TB) MTFDDAK7T6TDS - Micron 5210 ION (7.68TB) MTFDDAK7T6QDE - Samsung PM883 (7.68TB) MZ7LH7T6HMLA Platter HD (max capacities of model-series): - Seagate BarraCuda (5TB) ST5000LM000 I'm using my DS620slim with (4) 5TB ST5000LM000 platters in RAID-5 (15TB = 13.6TiB usable), and (2) 500GB Crucial MX500 NAND drives in a RAID-1 (500GB = 465GiB usable) read-write SSD Cache. For more information, see Synology's site on the DS620 HDD/SDD compatibility, as well as the SSD Cache articles. The SSD Cache requires 416KiB of RAM per 1TiB of storage, so 192MiB (0.2GiB) of RAM for my 500GB SSD Cache.

Your older drives can be used with the Synology DiskStation DS620slim 6-Bay NAS Enclosure, however the data may not be accessible. Drives do not have to be the same size.
