This article covers トランセンドジャパン Transcend Mac専用SSD 480GB アップグレードキット(Thunderbolt 対応ケース付) MacBook Pro.

Overview

The Transcend TS480GJDM855 (JetDrive 855) is a dedicated SSD upgrade kit designed to breathe new life into aging Macs. It features a 480GB NVMe PCIe Gen3 x4 SSD with sequential read speeds up to 1,600MB/s and write speeds up to 1,300MB/s. The package includes a precision screwdriver set (T5 & P5) and a Thunderbolt-certified aluminum enclosure, allowing you to repurpose the original SSD as a portable drive after the upgrade. This kit targets MacBook Pro (Retina), MacBook Air, Mac mini, and Mac Pro models from 2013 to 2017 running macOS 10.13 or later. It's a cost-effective midrange solution for users who want to dramatically improve system responsiveness without buying a new Mac. The bundled Thunderbolt case adds versatility for data migration and external storage.

Compatibility Guide

Compatible models: - MacBook Pro (Retina): 13" (Late 2013 – Early 2015), 15" (Late 2013 – Mid 2015) - MacBook Air: 11" (Mid 2013 – Early 2015), 13" (Mid 2013 – 2017) - Mac mini: Late 2014 - Mac Pro: Late 2013 Requirements: macOS 10.13 or later. Note that Mac mini and Mac Pro upgrades require a separate Phillips screwdriver (not included). The internal SSD is M.2 2280 form factor with NVMe interface; the included Thunderbolt case works with any Thunderbolt-equipped Mac.

Product Info

Released around 2018, the JetDrive 855 carries a typical retail price of ¥30,000–¥40,000 depending on availability. It comes with a 5-year warranty. Market positioning is entry-to-midrange; it offers NVMe speeds at a more affordable price than Apple's own upgrades. The kit contains the SSD, two screwdrivers (T5 & P5), the Thunderbolt aluminum case, and a manual.

Best Use Cases

Reviving older MacBooks: If your MacBook Air or Pro feels sluggish, swapping the original SSD for this NVMe drive will noticeably speed up boot times and app launches. Creative professionals: Photographers and video editors handling large media files will benefit from the faster read/write performance, both internally and as an external drive via the Thunderbolt case. Budget-conscious Mac users: For those who aren't ready to splurge on a new Mac, this kit offers significant performance gains at a fraction of the cost, and the enclosure ensures the old drive isn't wasted.

Things to Consider

Compatibility is limited to specific model years; verify your Mac's exact model before purchasing. The 480GB capacity may fill up quickly for users with extensive media libraries. Mac mini (Late 2014) and Mac Pro (Late 2013) require a separate screwdriver not included in the box. While the NVMe Gen3 x4 speed is a huge leap over SATA SSDs, it's not as fast as modern Gen4 drives – but for the targeted older Macs, it's more than adequate. Additionally, upgrading to macOS Monterey or later may require temporarily reinstalling the original Apple SSD to complete the firmware update before swapping back to the JetDrive. Note: This kit does not support Macs with soldered storage or models newer than 2017.*
