Silicon Power Bolt B80 USB 3.1 External SSD Review

SSD by stefan @ 2018-02-20

The Bolt B80 USB 3.1 External SSD from Silicon Power does sport a premium look thanks to the aluminum construction but is also easy to carry along. It comes with military-grade shockproof protection, but also rubber covers/gaskets in order to prevent water and dust penetration. For signaling data transfer activity, the product is provided with a white LED and its modular design along with the easy disassembly procedure does allow the user to replace the mSATA SSD with any other model/capacity.

Introduction

 

 

We would like to thank at first Silicon Power for supplying a sample of their Bolt B80 USB 3.1 External SSD for testing and reviewing.

Packaging, A Closer Look

Silicon Power has recently launched a new series of portable SSDs, for fast transfer rates and low latency; these are available in 120GB, 240GB and 480GB variants and do support the USB 3.1 Gen 2 bus (also backwards compatible) and do use the Type-C connector. The product is shipped in a stylish cardboard enclosure, with some product highlights listed right on the top cover:

 

 

 

Some more product details can be found on the side:

 

 

 

On the bottom side of the enclosure, we will get to see the package contents list, but also the technical specifications:

 

 

 

After removing the top cover, we will get to see that both the Bolt B80 SSD and its bundle are held in foam material, so they won’t get scratched during transit:

 

 

 

A User Manual can be also found, which contains general instructions on how to operate the storage device:

 

 

 

 

B80 does only weight 53g, sports an aluminum housing and its dimensions are 75 x 75 x 11.9 mm; it is 122cm military-grade shock resistant (MIL-STD 810G 516.7 Procedure IV transit drop test):

 

 

 

The Type-C USB port is fully covered:

 

 

 

 

A Closer Look Contd.

The opposite side presents itself with two cut-outs, which do serve for fitting a possible lanyard:

 

 

 

On the bottom unit area, we can find a circular rubber foot; the total drive capacity is also written in the middle and in order to disassemble the unit, we must remove the six screws:

 

 

 

As we have seen with other high-end peripherals, the USB transfer cable is braided, while the connectors do follow the design style of the B80:

 

 

 

 

 

After removing the bottom aluminum cover, we will get to see the gaskets for vibration dampening purposes but also for keeping dust and water out:

 

 

 

Bolt B80 does feature a simple construction, with a mSATA to USB 3.1 Type-C adapter board and the mSATA SSD itself:

 

 

 

Thanks to the modular design, we can replace the supplied SSD with any other mSATA model, if desired:

 

 

 

 

The supplied SSD is a DRAM-less design:

 

 

 

This part is driven by a PHISON PS3111-S11 single-core SSD controller that supports technologies such as SmartECC, SmartFlush, GuaranteedFlush, SmartZIP, built-in static and dynamic wear-leveling, power saving features but also end-to-end Data Path Protection:

 

 

 

The NAND Flash ICs are from Micron and carry the NW838 code name; these are 3D TLC, so a drop in performance is expected after the SLC portion, which acts as a cache has been filled:

 

 

 

On the opposite side of the PCB, we have placeholders for two additional ICs (the 480GB version comes with these installed):

Conclusive Thoughts

The Bolt B80 USB 3.1 External SSD from Silicon Power does sport a premium look thanks to the aluminum construction but is also easy to carry along. It comes with military-grade shockproof protection, but also rubber covers/gaskets in order to prevent water and dust penetration. For signaling data transfer activity, the product is provided with a white LED and its modular design along with the easy disassembly procedure does allow the user to replace the mSATA SSD with any other model/capacity.

 

 

 

As we have mentioned before, Bolt B80 comes with TLC NAND Flash, which has a known behavior: after the SLC cache portion has been filled, the transfer speed will get slower, so if you are transferring large data quantities at once, you will eventually reach the minimum speed of about 47MB/s (as we have found from our tests):

 

 

 

The Write test of the HD Tune Pro utility does show the moments when the SLC cache kicks in:

 

 

 

At the moment of the review, the Bolt B80 120GB could be found online for about 72.25 Euros, the 240GB version for about 108 Euros, while the 480GB version could be had for about 185 Euros.

 

Silicon Power Bolt B80 USB 3.1 External SSD is Recommended for:

 

 

We would like to thank again to Silicon Power for making this review possible!
