OWC Thunderblade Thunderbolt 3 SSD: Speed vs Transfer Size
Related: Other World Computing, OWC Thunderblade, SSD, storage, Thunderbolt, Thunderbolt 3, USB
MPG tested the 8TB OWC Thunderblade Thunderbolt 3 SSD. Available in 1/2/4/8TB configurations.
This page shows the sustained transfer performance of the 8TB OWC Thunderblade using I/O transfer sizes from small to very large.
Performance as tested: speed vs transfer size
During this test, the Thunderblade barely got warm and was completely silent.
Transfer speeds with 32 KB transfers is already higher than many SSDs peak at, with 64KB transfers exceeding the speed possible with USB 3.1 SSDs. By 128KB, speed exceeds that possible with USB-C/USB 3.1 gen2.
At 256KB, speed reaches levels that only the fastest SSDs can achieve, substantially faster than even possible with Thunderbolt 2 devices. Thereafter, speed climbs steadily to the 2600 to 2700 MB/sec maximum.
Note to application developers (Adobe?): this graph shows clearly that transfers should be at least 8MB in order to to extract 90% or more of the peak performance.
Speed in is real-world, including operating system file system overhead (not unrealistic driver-level calls).
