Flash memory has also seen a recent drop in prices, and this has made high-capacity drives affordable.Current external flash storage devices fall under one of four categories.They belong to the second category in the above list, placing a SATA drive behind a USB 3.1 Gen 2 bridge.
![]() Capacities have been steadily increasing, though very few high-end models boast of peak performance in the 300 - 400 MBps range. Most low-end and mid-range thumb drives have write speeds of the order of 20 - 80 MBps, and read speeds of the order of 100 - 150 MBps. Over the last few years, we have had vendors place a 2.5 SSD board behind a SATA - USB 3.0 bridge. These have now evolved into M.2 SATA SSDs behind a much smaller and more power-efficient SATA - USB 3.1 Gen 2 Type-C bridge. Such external SSDs now make up the bulk of the mid-range and high-end bus-powered external direct-attached storage devices. Consumers requiring very bus-powered external storage with very high performance are served by Thunderbolt 3 SSDs that are surprisingly affordable despite their performance profile. These SSDs put a M.2 PCIe NVMe SSD behind a Thunderbolt 3 controller and deliver performance equivalent to an internal PCIe 3.0 x4 M.2 NVMe drive (up to 3 GBps). ![]() However, the WD My Passport SSD 2TB variant uses a different firmware (in addition to the changed capacity) that enables hardware encryption compared to the one in the SanDisk Extreme Portable SSD. Wd My Passport Can It Work On Pc Free Months OfValue additions include two free months of the Adobe Creative Cloud Photography Plan, and a bundled Seagate Rescue data recovery service plan. The internals are essentially the same as the Fast SSD - Toshiba BiCS 64-layer 3D TLC coupled with a re-branded Phison S10 controller behind an ASMedia ASM235CM bridge chip. The unit also has extensive thermal protection, similar to the Seagate Fast SSD. That version, despite sporting a USB 3.1 Gen 2 interface, was handicapped by the planar TLC-equipped SanDisk X400 inside. Western Digital has since updated the product line to use the WD Blue 3D NAND SSDs with 64-layer 3D TLC flash. ![]() Despite the adapters Type-C female interface, the included Type-C to Type-C cable can be plugged into it in only one orientation (indicated by a triangular mark on the adapter as the cable). Wd My Passport Can It Work On Pc Software Installers ToIt includes some software installers to enhance the utility of the product - WD Discovery Drive Utilities, WD Backup, and WD Security. The WD Backup software can be used to create scheduled backups of certain folders on the PC to the SSD. WD Security allows the setting of a password (up to 25 characters) that activates the hardware encryption features on the drive. The drive needs to be unlocked with the password upon system restart, or drive reconnect, or exit of the system from sleep mode. Evidence from a teardown video lends credence to the fact that the internal MILAN II M.2 SATA SSD is indeed a variant of the WD Blue 3D NAND SSD seen in the SanDisk Extreme Portable version. MILAN II is likely different from the retail variants of the WD Blue 3D NAND SSD in terms of firmware features such as self-encryption.
