The storage specialist Symply has significantly upgraded the storage volume of its portable Spark Thunderbolt Shuttle RAID systems thanks to Seagate's new hard drives, which enable even larger capacities than before. By using Seagate's 30 TB Exos M hard drives with Heat-Assisted Magnetic Recording (HAMR), the 8-bay models now achieve a capacity of up to 240 TB (8 x 30 TB), while the 4-bay variant offers a maximum of 120 TB (4 x 30 TB). This increases the storage density by around 25 percent compared to the previous generation. A typical application for the SPARK Shuttle RAID drives is post-production, where large amounts of raw material are often processed.

Technical Basis: Mozaic HAMR from Seagate
The new hard drives use heat-assisted magnetic recording (HAMR). In this process, areas to be written are briefly heated by means of a focused laser, which reduces the magnetic resistance of the material and allows data to be arranged more densely. After cooling, the information remains stably stored without the need for renewed heating during reading.
RAID Options and Interfaces
The Spark Thunderbolt Shuttle RAID systems support various RAID modes, including RAID 5 and RAID 6 for increased reliability. The drives are hot-swappable, enabling quick replacement during operation.
Two Thunderbolt 3 ports serve as interfaces. The maximum read and write speeds depend on the RAID mode used (RAID 0, 1, 5, 6, 10 or JBOD). Depending on the configuration, the standard SPARK models achieve up to 1,711 MB/s when reading and 1,639 MB/s when writing. The SPARK-XT variant with Multi-Actuator-Drives increases the transfer rates in RAID 5 to up to 2,950 MB/s when reading and ~1,980 MB/s when writing.
