Equipped with five 1TB SATA 3.5" Enterprise NAS hard drives in its five 3.5"/2.5" drive bays, the ioSafe 1517 5TB 5-Bay NAS Array (5 x 1) is engineered to protect business-critical data, enhance recovery times, and deliver strong reliability while protecting up to 5TB of data from natural and man-made disasters. It is fireproof up to 1550°F for up to 30 minutes and also protects data from while fully submerged in up to 10' of fresh or salt water for up to 72 hours. Cloud-enabled and powered by Synology's DiskStation Manager operating system, the 1517 NAS includes apps for collaboration, file syncing and sharing, video surveillance, and more.

ioSafe's 1517 has five drive bays, each of which natively supports 3.5" SATA hard drives, as well as 2.5" SATA hard drives and SSDs. It is powered by a 1.7 GHz Annapurna Labs Alpine AL-314 Quad-Core processor, which will allow you to run multiple functions simultaneously, while 2GB of DDR3L RAM will allow quick access to frequently used files and programs. Also featured are two USB 3.0 Type-A ports and two eSATA ports which allow it to be connected to your Windows or Mac system. Network connectivity is achieved via four Gigabit Ethernet ports with Link Aggregation and Failover support, or a separately wireless dongle for Wi-Fi connectivity.

The 1517 runs on Synology's DiskStation Manager (DSM) operating system, which helps simplify managing your NAS, as well as accessing and sharing data. A variety of RAID modes are supported, which help provide users with data redundancy, speed, or a combination of both. Supported RAID modes include RAID 0, 1, 5, 6, 10, Basic, and Synology Hybrid RAID. For those who do not require a RAID, JBOD is also available, allowing each drive bay to be individually utilized.

ioSafe has engineered this NAS to be energy efficient. Not only does it use dual 80 x 80mm fans to help keep the system running cool, the server supports numerous scheduled power on / off cycles and hard drive hibernation to further minimize power consumption and operational expenses. The 1517 operates on 100-240 VAC at 50/60 Hz and includes an accessory pack, a 200W AC power adapter, an AC power cord, and two RJ45 LAN cables. Protection is provided by a limited 5-year hardware warranty, along with five years of ioSafe's Basic Data Recovery Service (DRS). DRS includes free in-house data recovery, up to $5000 per TB coverage for third-party forensic data recovery services, coverage for servers or other devices attached to the ioSafe 1517, and advanced replacement of the ioSafe 1517.

Related Questions and Answers

Q: 1. Does it come with the drives installed and configured, or just bundled to purchase? Also, are the discs hot swappable?

A: The Synology 60TB DiskStation DS1522+ 5-Bay NAS Enclosure Kit with Seagate IronWolf NAS Drives (5 x 12TB), B&H # SYDS1522P60K, does not come with the drives pre-installed or configured; it is only bundled to purchase together. Excluding the M.2 slots, the drive bays have hot-swap functionality.

Q: 2. I found it really hard to look for footage inside the nas because it’s slow, what should I do to increase the speed? Already installed two fast nvme.

A: NAS performance can be linked to many factors, such as drive speed, the type of RAID you are using, and the speed of your local network. If you have your DS1522+ configured in RAID 1 or JBOD, consider using a faster configuration such as RAID 0 or 5. If the NAS is connected to a network switch, make sure that it is using a gigabit port. If it is connected directly to your router, make sure that your local network is operating with appropriate speed and bandwidth and that the computer you use for editing is using a wired Ethernet connection instead of WiFi.
