Synology NAS SSD with 2.5 and M.2 and new expansion cards


Synology starts with its own SSD product range, which is intended for use in its own NAS systems. With the SAT5200, SNV3400 and SNV3500 models, Synology offers three different models, which differ in the form factor and the interface used.

The SAT5200 uses the 2.5-inch format and the SATA interface with 6 Gbit/s. The SNV3400, on the other hand, uses the M.2-2280 form factor and Nvme with Pcie 3.0 x4. The SNV3500 uses the same interface but the larger M.2-22110 form factor.

The two Nvme Ssds are initially only available with a capacity of 400 GB, while the SAT5200 will be available in capacities of 480, 960 and 1,920 GB. The SAT5200 is specified with 1.3 Drive Writes Per Day (DWPD), which guarantees Synology that the SSD can be written over full capacity 1.3 times a day. For the SNV3400 and SNV3500, this DWPD value is 0.68, which is, for example, less than the Seagate Ironwolf 510, which can be fully described once a day.

According to Hewitt Lee, Director of Synology Product Management Group, the use of SSD cache in NAS systems increased 2.4 times in 2019 and pure SSD setups increased by 53 percent. According to their own information, they therefore decided to offer their customers themselves more reliable drives than those available on the market. For this purpose, the new SSD models have been tested for thousands of hours in their own systems.

Competitive IOPS at SSD debut


According to Synology, the SAT5200 consistently delivers up to 98,000 IOPS for random reading and 67,000 IOPS for random writing. The two Ssds of the Synology SNV series, on the other hand, provide 205,000 IOPS for optional reading and 40,000 IOPS for permanent optional writing. If you use the Seagate Ironwolf 510 with 480 GB for comparison, this reaches 193,000 IOPS in random reading and 20,000 IOPS in random writing. Seagate’s 960 GB model reaches 345,000/28,000 IOPS Read/Write. Synology estimates the sequential reading (128KB, QD32) of the SNV series to be 3,100 MB/s, the sequential writing (128KB, QD32) to be 550 MB/s.

Protection against power failure and 5 years warranty


The SAT5200 and SNV3500 protect the data integrity by a built-in protection against power failure. All new models support life analysis in Diskstation Manager, where Diskstation Manager 6.2.3 or later is required. The guarantee of the new Ssds is 5 years.

The SAT5200 has a suggested retail price of around 190 euros for the 480 GB model, 345 euros at 960 GB and 618 euros at 1,920 GB. The SNV3400 with 400 GB, on the other hand, is supposed to cost around 155 euros, while the RRP of the SNV3500 with 400 GB is 178.50 euros.

New expansion cards: Synology M2D20 and E10M20-T1


With the M2D20 Nvme SSD card, Synology is launching a successor to the M2D18. This is an M.2 SSD adapter card that uses Pcie 3.0 x8.

The E10M20-T1 expansion card, on the other hand, offers two M.2 slots, which support the form factors 2280 and 22110, and a 10 Gigabit RJ 45 network connection (10GBASE-T/NBASE-T), which supports 1, 2.5 and 5 Gbit/s in addition to 10 Gbit/s. This card also uses Pcie 3.0 x8.
