The Synology DS620slim is one of the most compact NAS servers available today. It supports up to six HDD/SSDs for plenty of storage if you equip it with large-capacity drives. We measured power consumption to be low, and the same goes for its operating noise.

operating noise is variable based on the hard drives you use so YMMV. The price isnt tooooooo bad(????) but at least they've specc'd it with an Intel CPU and not some mediocre and woefully underpowered Marvell SoC along side expandable memory. Providing they fixed the power issues with their previous units then this seems like a decent buy.
 
DSM is still the best OS and this product had so much potential... :( but the lack of 10gb network connection on an all SSD NAS is not really excusable by Synology versus their competition. Having an anemic low power CPU is typical of Synology, but dual core is kinda pushing it these days. Also not that this unit has much grunt to be used as a small server with VMs and Docker services, but the optional Intel Spectre/Meltdown patches also slow down these NAS units quite a bit.
 
Oof that thing is a real dog!
 
@crmaris the spec table needs to be updated.
Storage
6x 3.5"/2.5" SATA II/III​
 
I would have liked to have seen support for at least one NVMe (two being ideal), at least one PCIe port if no built in 10GbE support and at least one eSATA or eSAS port.

I guess we should be glad this isn't an Atom SoC or an ARM processor but realistically this isn't much better.

Synology does make some good products and DSM is IMO great. However, their hardware design choices are sometime very perplexing.
 
While these reviews are interesting as it relates to advances in technology. I sorely miss the opportunity to look at how it impacts every day usage. How often does one do a rebuild ? How often does large amounts of data get transferred to a disk ? Im not suggesting the data isn't usefil in a strict hardware evaluation sense. Being able to see how it delivers in the real world would add a lot to its usefullness. We no longer use an NAS and to my eyes, the best thing about it was if there was a fire... it' real easy to "Grab 'n Go",

We have a SOHO network in a 200 year old dairy barn where the engineering office is in the hayloft. We design water / wastewater/ industrial plants, commercial buildings, bakeries, restaurants, commercial kitchens, etc. The network has (5) office PCs / Laptops w/ 34 years of business and work product files and (6) PCs / Laptops w/ 34 years of personal data on the HO side. On the SO side, one would typically open 1-6 files a day, along with 2-3 spreadsheets, site photographs and 1-3 WP files, as well as web browsing for product info. HO side I imagine is similar to very one else. Would love to see everyday performance .

In consideration of who is using an NAS, it's not datacenters, it's not offices with > 10 - 15 PCs, ... it's not grandma looking at pics of the grandkids or mom keepimg track of her recipes . It's small business owners, its those with substantial media libraries. It would be useful to see how a top end NAS impacts a small network ... is the NAS performance bottlenecked by network performance ? How long does it take to open / save a file from NAS storage device to user's desktop ? How does it differ ?

a) How long to open / save the average size CAD file ? Our largest is < 12 MB. Median size is 300 KB
b) How long to open / save the average size Word Processing file file ? Our largest is < 272 MB with tons of embedded JPGs. Median size is 102 MB
c) How long to open / save the average size Spreadsheet file ? Our largest is < 8 MB. Median size is 35 KB
d) How long to open / save the average size JPG file ? Our largest is < 17 MB. median size is 94 KB
e) How long to open / save the average size MOV file ? Our largest is <1 GB. median size is 2 MB
 
Have you read the review carefully? I use a custom made app that does exactly what you ask for, real-life file transfers with various types of files. It also moves files from one folder of the NAS to another, which is the toughest part. Moreover, the diskspd sessions with the IOPS are a good indication of the performance under all scenarios.

Rebuilding: no modern NAS will rebuild without a good reason (a problem in one of the HDDs). In case you need it though, I provide time periods and Wattage readings.
 
I would have like to see pics with a SSD installed like you did with the HDD. I'd like to think noise would be reduced with all SSDs but I'm sure replacing the cheap loud fan would do better.
