OWC 40TB SSD: RAID-0 Transfer Size Performance

OWC Thunderbay Mini

The Thunderbay 4 Mini RAID-5 edition is available with SSDs in capacities from 1TB to 40TB. MPG strong recommends the RAID edition.

Thunderbay 4 Mini configurations (non RAID) are also available, as well as hard drive configurations are also available.

The graph below shows transfer speed for transfer sizes from 32KiB to 512 MiB with a RAID-0 stripe utilizing a 64K stripe size.

Any transfer of 32 or 64K essentially is a single-drive access, since these sizes are less than or equal to the stripe size. At 128 KiB, two drives get involved, and 4 drives with 256 KiB start taking full advantage or the RAID-0 stripe.

Transfers must be fairly large for peak speeds to be achieved, which is true of all drives. A well written application will use large buffers and perform overlapping I/O to “feed the beast”. Realistically, a device this large is probably being used to store huge amounts of data that has to be written or read very fast, so the most relevant performance figures are the 1 MiB and larger transfers.

Figures are in MiB/sec. Multiply by 1.048576 for MB/sec.
