The SSD market has been steadily gaining traction. Prosumers who work in areas like videography and photography saw real benefits with SSD, which is able to provide improved reliability and higher transfer rates. As mainstream consumers are increasingly educated with the advantage of SSD technology, many are slowing migrating from traditional hard disks to SSDs as a main back up and storage solution. Price and availability is perhaps the only reason limiting a full scale mainstream adoption of SSD technology.
Plextor released the Plextor EX1 earlier this month. We managed to get our hands on a unit, and in this review, we will be testing out the new Plextor EX1 Portable SSD in terms of its design and performance.

The Plextor EX1 interfaces with the host computer via the USB 3.1 standard. The new USB 3.1 standard promises better signalling between the device and host computer. This has resulted in a much higher transfer rate capabilities for peripherals. Specifically, USB 3.0's bandwidth is rated only at 5Gbps, while USB 3.1 is rated at 10Gbps. We were sure that the SSD's memory speeds will not be bottlenecked by its own transfer interface with USB 3.1.

The specifications of the system that was used for the tests are as follows :
- Intel Core i7 6770K at stock settings
- ASUS Sabertooth Z170 S motherboard
- 8GB DDR4 RAM
- ASUS STRIX RX470
- Cooler Master V1000 PSU
- Windows 10 64 bit Enterprise Edition
- Plextor EX1 SSD (128GB)
- ASMedia USB 3.1 Controller (on the ASUS motherboard)
Seq Read : Up to 550MB/s
Seq Write : Up to 500MB/s

Noting that most users who uses a SSD as an external storage medium are mainly videographers and photographers, the type of files they deal with are usually multiple large files. Since files are large, the sequential read and write speeds should show the kind of speeds that is provided by transferring these videos and photo files. In fact, these astonishing numbers could possibly make the Plextor EX1 portable SSD one of, if not in fact, the fastest external SSD available in the market (based on the time of the review).

Windows File Transfer
In a real world test, we transferred a single large zip file from a local SSD to the Plextor EX1. The NVMe Plextor M8Pe was selected as the sending SSD. This prevents any form of read bottlenecks from other storage units.
We managed to consistently reach a transfer rate of 398MB/s by sending a 4GB zip file from the Plextor M8Pe to the Plextor EX1. This test was done with the EX1 plugged into an USB 3.1 port. These numbers really do show how fast and furious this external SSD is!

The EX1 will be available in three different capacities (128 / 256 / 512 GB) to choose from, and the entire series comes with a 5-year limited warranty from Plextor.
