Pulsed Media Dragon-R

The Dragon-R line is Pulsed Media's highest-tier shared seedbox product. Each Dragon-R server runs on AMD EPYC hardware with 128-256 GB of ECC RAM, connects at 20 Gbps (shared among approximately 26 users), and uses RAID10 storage, which combines the striping performance of RAID0 with the mirroring redundancy of RAID1.

The plans are named after fictional dragons: Mushu, Toruk, Shenlong, and Temeraire.

Plans

Toruk	5 TB RAID10	20 Gbps (shared)	50,000 GiB	Finland
Shenlong	10 TB RAID10	20 Gbps (shared)	75,000 GiB	Finland
Temeraire	16 TB RAID10	20 Gbps (shared)	Unlimited*	Finland

How Dragon-R compares to other PM plans

	V1000 / M1000	V10G / M10G	Dragon-R
Network	1 Gbps	10 Gbps	20 Gbps (shared)
RAID	RAID0 (V) or RAID5 (M)	RAID0 (V) or RAID5 (M)	RAID10
Drive redundancy	None (V) or 1 drive (M)	None (V) or 1 drive (M)	Mirrors every drive
Users per server	Shared	Shared	Shared (~26 users)
Software	PMSS	PMSS	PMSS
Torrent clients	rTorrent, qBittorrent, Deluge	rTorrent, qBittorrent, Deluge	rTorrent, qBittorrent, Deluge

All plans run the same PM Software Stack, use the same web interface, and support the same torrent clients. The differences are in network speed, RAID level, and storage capacity.

RAID10 storage

RAID10 creates a mirrored pair for every data stripe. In a four-drive RAID10 array, each piece of data exists on two drives. If one drive fails, its mirror contains a copy, and the array continues operating without data loss.

Compared to the RAID0 used in V-series plans, RAID10 sacrifices half the raw drive capacity for redundancy. A server with 32 TB of raw disk space yields approximately 16 TB of usable storage in RAID10, versus 32 TB in RAID0. What you lose in capacity you gain in fault tolerance and consistent read performance (reads can be served from either mirror).

Compared to the RAID5 used in M-series plans, RAID10 has faster write performance because it writes mirrored copies directly instead of calculating parity. Rebuild times after a drive failure are also shorter because only the mirror of the failed drive needs to be rebuilt, not the entire array.

20 Gbps shared network

The 20 Gbps figure is the server's uplink to the datacenter network, shared among all users on the server. Under normal conditions, each user has access to a large share of this bandwidth. During peak usage, when many users are actively seeding or downloading, the 20 Gbps pool is divided across active connections.

This is still significantly more bandwidth per user than a 1 Gbps plan. Even split 26 ways evenly (worst case, all users maxing out simultaneously), each user would have roughly 770 Mbps, which is above what a 1 Gbps plan can provide at full allocation. In practice, not all users are transferring at maximum speed at the same time, so available bandwidth per user is typically much higher.

For private tracker racing, the 20 Gbps uplink provides a large seeding capacity during the critical first minutes after a torrent is posted.

Who Dragon-R is for

Dragon-R fits users who want more network headroom than 10Gbps plans provide, combined with the peace of mind of RAID10 redundancy. Typical use cases:

Private tracker users who race large content (season packs, 4K remuxes) and want maximum seeding bandwidth
Users with large media libraries who want both speed and drive redundancy
Users who transfer large amounts of data between the seedbox and home or cloud storage

If you do not need the 20 Gbps headroom, the V10G and M10G plans offer 10 Gbps at a lower price point. If redundancy is not important and you want maximum storage per euro, V-series RAID0 plans give the most space.
