Hard Disk Driver (Hard Disk Driver) is a few years ago the PC industry mainstream storage devices, Hard Disk also really have a piece or even a few parts of "Disk," but also limited to the Disk this physical structure, the traditional Hard Disk read speed limit is not high, even if the desktop level 7200 drive Hard Disk is also run dissatisfied with SATA bandwidth.
With the continuous progress of semiconductor technology, solid-state hard disk (SSD) is also popular. The current mainstream notebook products are all using SSD. Solid-state drives don't have a disk itself; they typically have a master chip +RAM+ flash memory, and their read and write speeds are an order of magnitude or faster than traditional HDDs.
The computer's internal memory speed has been improved, and the external memory, of course, needs to be upgraded. Today, I'm going to bring you the experience and performance test of Western Digital's My Passport accompanying SSD version. Here first, thanks to the public test Jun and to provide trial products of Western Data.
Unpacking and exterior design
The SSD My Passport is the SSD version of Western Digital's classic My Passport mobile hard drive series. It uses USB 3.2 Gen2 interface and NVME technology, with a theoretical transfer speed of 1050MB/s, twice the standard SATA interface rate.
The yellow and white packaging is simple. The unpacked family photo includes the hard drive, USB-C to USB-C data cable, USB-C to USB-A adapter, and instructions.
My Passport has a metal-encased design that measures just 100 x 5 x 9mm and weighs 45.7g. The oblique stripe design on the front makes the fuselage no longer monotonous, while the back is made of white plastic material. The whole machine's appearance is considered to be anti-impact, which can resist falling 1.98 meters high.
Compared to the WD Elements portable hard drive I bought a few years ago, the SSD in My Passport has a considerable advantage in both body and weight. The SSD in My Passport has a maximum capacity of 2TB, and the WD Elements in My hand is also 2TB. The difference in size and weight is apparent. In addition to the size advantage, SSD is even more potent than HDDs. Except for scenarios where super-large storage requirements are not required, SSD has indeed completely replaced HDDs.
The SSD that comes with the Passport uses USB-C. Officially, it supports both Windows and Mac platforms, but in tests, iPad Pro, iPad Air, and phones can connect directly. Large files like video can be copied to a portable SSD and edited using the iPad without taking up too much of its storage capacity.
The SSD that comes with the My Passport is small, and it has a significant advantage over a traditional mobile hard drive that you carry around daily. If you calculate a 5MB image, 1TB is enough to store 200,000 photos, and if you figure a 100MB video, 1TB can hold about 10,000 videos. For the storage needs of ordinary users, 1TB/2TB My Passport is enough.
The performance test
The capacity of the accompanying SSD of My Passport in My hand is 1TB. The model identified in CrystalDiskinfo is SN550E, and the interface type is NVME Express.
Under Windows using CrystalDisk Mark test, sequential read speed is 933MB/s; sequential write speed is 962MB/s; this speed has been much faster than any SATA SSD (about 500MB/s), the performance of it to do Win2Go hard Disk is enough.
Copy the file using a 44GB large file for testing; the measured write speed reached 824MB/s.
In addition to Windows, My Passport can also support Mac platforms, but due to the lack of IO capability of My M1 Mac Mini itself. The measured write and read speeds are 771MB/s and 717.9MB/s, respectively, but the read and write performance is sufficient for Prores 422 HQ and Cinema DNG Raw 4K video clips.
conclusion
My Passport's accompanying SSD is a tiny, portable, mobile SSD with a metal body designed for business users and a fast reading and writing speed of 1,000 megabits per second. Encryption is supported to store both corporate data and personal privacy files for security. The maximum 2TB capacity can also store enough project files or video material. Compatibility with Windows and Mac platforms and up to five years of warranty are also bonus points.
A worthy improvement is that there is no free portable bag. If you can randomly attach a hard disk + data line storage bag, it will be more convenient for users to use.
