Synology Video Station:Manage all your movies, TV shows, and home videos. Stream them on multiple devices or share them with friends and family. In the first of our enterprise workloads, we measured a long sample of random 4k performance with 100% write and 100% read activity using the SMB protocol. The DS1513+ was in line with the DS1515+ (Reds) in terms of write functions (532 IOPS and 546 IOPS, respectively), but it fell short in read functions, which were best in the DS1515+ loaded with Reds (365 IOPS). When configured in iSCSI, the DS1515+ loaded with Reds claimed the top spot in both read and write functions, with 1412 IOPS and 299 IOPS, respectively (although the standings were fairly even overall). Hunting around on the web it looks like there are a couple of issues with the DS1515+ including the atom chip issue and resistor failure related to the power button.

Added support for the configuration of date and time formats in personal account settings and Control Panel. Fixed an issue where CMS-managed servers might disconnect from a CMS Host that has been updated to DSM 6.2.4. Fixed the issue where the LED indicators on the drive slots of RS4017xs+ and RS2818RP+ might not work properly. After this amount of time I’m willing to try things that make sense, but still suspect the power supply. I wish I had a way to test under load at home.Synology has upgraded the cooling of the DS1513+ to include detachable fans and this feature has been carried on to the DS1515, which should make it easier to clean or replace if they fail. According to DS1512+ users, this machine recognizes 4GB of RAM. To install 4 gigabytes, you will have to remove the 1GB module and replace it with 4GB module. Fixed an issue where iSCSI Manager might not open for the incompatible format of iSCSI LUN configuration files set up before DSM 5.2. Synology Office: Create documents, spreadsheets, and slides in a multi-user environment. Real-time synchronization and saving make collaboration.

Fixed an issue where when users access files on DSM using Windows software via SMB, system performance might be affected. This is because of Windows software's continuous attempts to access the shared folders to which it has no permissions. Maximum Internal Raw Capacity: 30TB (6TB HDD x5) (Capacity may vary by RAID types) (See All Supported HDD) Fixed the issue where the application permissions settings might not be applied properly to the Domain Users group when such group in Windows AD domain was named other than "Domain Users". Enhanced the stability of SSD caches when multiple processes are accessing the same cache at the same time.

Compatibility and Installation

Fixed an issue where external hard drives of WD My Book might not be recognized if DSM is rebooted while the drives are in hibernation. Improved system responsiveness by reducing the latency of the Btrfs file system in certain scenarios. Fixed an issue where after users updated to DSM 6.2.4, iSCSI targets mapped with LUNs created on DSM 6.0 and before became offline and couldn't be enabled. What can both NAS server’s do? Before I get down to which of these units is better at what task, I think it is important to know the things that BOTH of these NAS devices can do. So, whether you decide upon the Synology DS1517+ released recently, or the Synology DS1515+ released in 2015, you will definitely be able to: Fixed an issue where the date and time formats for scheduled tasks were inconsistent in the widget and system settings.

Fixed an issue where local users may fail to log in via SMB on specific Windows versions after adding their NAS to a Synology Active Directory domain. It theoretically can be replaced with another larger volume module, but you should keep in mind that if you tamper with a preinstalled RAM module, the warranty will be void. Fixed an issue where the fan couldn't resume in full speed mode after a system reboot on models with the V1000 platform.When first creating SHA cluster, user new to SHA can choose to only replicate system configuration to shorten setup time. Adjusted the fan speed to fix a potential overheating issue when a Synology network interface card (E10G18-T1, E10G18-T2, E10M20-T1, E10G21-F2, E25G20-F2) is used as the Heartbeat connection in an SHA cluster or for Open vSwitch. Specifically, the process, which can't be canceled, took about a day for my three 8TB hard drives in an SHR setup, during which the server worked at a slower performance. The similar "data scrubbing," a recommended periodical maintenance, also takes an incredibly long time to finish. Thin Provisioning LUN will become protected upon insufficient volume space, preventing clients from writing data to the LUN while allowing read-only access to the existing data.

Surveillance Station must be updated to version 9.0.1- 7673 or above to be compatible with this update.

Synology launches a cheap Amazon-powered NAS appliance

The Alpine processor has an integral AES-NI encryption engine but it's not as efficient as the Atom C2538. Copying our 25GB test file to an encrypted share on the DS1515 returned 63MB/sec whereas the DS1515+ mustered a higher 82MB/sec. From the Storage Manager app, we chose a single SHR (Synology Hybrid RAID) storage pool using all drives. You can opt for classic RAID arrays, but SHR is more flexible as it allows disks of different sizes to be mixed together without taking a hit on capacity and it supports single and dual-drive redundancy. Performance differences However in longer testing the NAS just sits with a flashing blue LED power light (no drives installed) which lead me to believe after further reading online I suspect it could be a corrupt bios or motherboard perhaps. The company skipped the 2019 model year. After that, we had the DS1520+. And now the latest DS1522+ is the 6th generation in the product line. The DiskStation DS1515 is aimed at home users as well as small businesses. Out of the box this NAS can handle five 3.5" hard drives, giving it a maximum capacity of 40TB using the latest 8TB drives, while the addition of two DX513 expansion units boosts capacity to a whopping 120TB.
