SilverStone Launches TS434U External 4-Bay 10Gbps SATA Hot-Swap Hard Drive Enclosure

SilverStone has launched the TS434U, a compact external hard drive enclosure designed for users who need high-capacity storage with modern connectivity. Measuring 158 mm × 173 mm × 210 mm, it holds up to four 3.5-inch HDDs or 2.5-inch SSDs using regular SATA I/II/III connections with full hot-swap functionality support. The enclosure has a USB 3.2 Gen 2 connection with a USB Type-C plug, delivering transfer speeds up to 10 Gbps. Inside, it has an ASMedia ASM2074 controller working with four ASMedia ASM235CM bridge chips to manage the drives. It runs on 100-240 V AC power and puts out 12 V/7.5 A DC, which is enough to run multiple drives. To keep things cool, it has a 120 mm fan at the bottom. It also has built-in protection to prevent the drives from overheating. The magnetic front door design allows removal and side attachment while concealing LED indicators when closed. Status monitoring includes power, fan, and individual HDD activity indicators using color-coded LEDs.

It's worth mentioning that the device operates as a non-RAID unit, requiring software RAID configuration through OS utilities for array functionality. You can get the SilverStone TS434U in black or white, and it comes with a 120 cm USB cable and a 1500 mm power cord. Price and exact store availability have yet to be announced.

Orico has some very interesting multi-bay drive solutions including ones that come with Hot and cold storage.

Very nice looking case, the internals seem very similar to the FS304-V 4-bay hotswap unit they just released some months ago.

If the 120mm fan is competent enough to cool down the drives (let us say maintain at the 40s at load), I will be getting some.

It would be nice to also have a 8-bay with 2x120mm like the QNAP TL-D800C (USB)


I hope it hits the shelves soon.

It sounds like an external power supply and not a build in one.

I do not see all sides of the product. I expect worse for the backside. Or a full picture of a real life scenario which includes an external brick power supply unit. Some companies do this on purpose to give a "clean look" impression.

These days I expect 20Gbps USB.

I found the backside picture. ( sorry I don't know how to not make that sound a little naughty )

You can't possibly max that out with 3.5" drives, and 2.5" are not too economical to put in these enclosures (plus they don't much need them).

I'm more concerned about the lack of vibration and noise proofing. HDDs can get extremely loud nowadays, especially if you put 4 in a closed case like this.

Yup, 4 drives in RAID 0 is still under 1 GB/s so a 10 GB/s USB C connection is really just a quality of life feature.

I'm still waiting for external HDD enclosures with OcuLink connection and a slot to put an HBA card there.

6-8 bays will be good.

@SilverStone Technology Is there any ETA on this?

A 8-bay would be great too, adding 2 x FS304-V and 2 x120mm fans

I wish I could attend IBC 2025 :S

Thanks in advance.

The TS434U should already be available in some Asian markets now. North America availability should start in first half of October 2025 with Europe to follow in second half of the month.
