Frequently Asked Questions
How much total storage can the Yottamaster PS400C3 actually hold?
Up to 88TB. It has four bays, and each bay supports a single 2.5" or 3.5" SATA drive of up to 22TB, so four maxed-out drives reach the 88TB ceiling.
Does the PS400C3 support RAID for redundancy?
No, this is a non-RAID enclosure. Each drive is presented to your computer independently, so there's no built-in mirroring or striping — you get flexibility to mix drives, but no automatic redundancy.
Will it work with both hard drives and SSDs at the same time?
Yes. Each of the four removable trays accepts either a 2.5" or 3.5" SATA HDD or SSD, so you can mix desktop drives, laptop drives, and SSDs across the bays.
How fast is the connection on the PS400C3?
It uses a USB 3.1 Type-C interface running the SATA III protocol, rated at transfer rates up to 6Gbps maximum. That bandwidth is shared across all four bays.
Is the PS400C3 compatible with Mac and Linux, or just Windows?
It's compatible with Windows, Mac, and Linux systems, so it fits into mixed-OS setups without needing special drivers.
How noisy is the cooling fan?
The enclosure uses an 80mm intelligent fan that automatically adjusts its speed based on drive temperature, ramping down for lower noise when the drives are running cool and speeding up as they heat.
