The command line version allows us to cherry-pick storage traces to run on a target drive. The storage workload involves games as well as multimedia editing applications. It comes out on top in the majority of the benchmarks.įor the second use-case, we take advantage of PC Mark 8's storage bench. In the above use-cases, the Supersonic Rage 2 manages to handle itself very well. BR: 10.7 GB Blu-ray folder structure of the IDT Benchmark Blu-ray (the same that we use in our robocopy tests for NAS systems).Videos: 16.1 GB collection of 244 videos (MP4 as well as MOVs) in 6 sub-folders.Photos: 15.6 GB collection of 4320 photos (RAW as well as JPEGs) in 61 sub-folders.In order to tackle the first use-case, we created three test folders with the following characteristics: The minor usage scenario is importing files directly off the DAS into a multimedia editing program such as Adobe Photoshop. The most common usage scenario is transfer of large amounts of photos and videos to and from the unit. Our testing methodology for DAS units also takes into consideration the usual use-case for such devices. As evident from the screenshot below, the performance can dip to the KBps range for 4K random acceses.īenchmarks - robocopy and PCMark 8 Storage Bench That said, these access traces are not very common in real-life scenarios.ĬrystalDiskMark, despite being a canned benchmark, provides a better estimate of the performance range with a selected set of numbers. These might be achievable in specific benchmark modes with appropriate queue depths, but they are not backed up by the ATTO benchmarks provided below. Patriot claims read and write speeds of 400 MBps and 300 MBps respectively. Synthetic Benchmarks - ATTO and Crystal DiskMark The full details of the reasoning behind choosing the above build components can be found here. Thanks to Asus and Corsair for the build components AnandTech DAS Testbed ConfigurationĪsus BW-16D1HT 16x Blu-ray Write (w/ M-Disc Support) This port supports UASP, even though the drive we are considering today doesn't advertise support for it. For devices with USB 3.0 connections (such as the Patriot Supersonic Rage 2 that we are considering today), we utilize the USB 3.0 port directly hanging off the PCH. Testbed Setup and Testing MethodologyĮvaluation of DAS units on Windows is done with the testbed outlined in the table below. The controller was introduced at CES earlier this year. We see that the Supersonic Rage 2 uses the Phison PS2251-08 controller with firmware version 5.00.10. Without opening up the unit, it is possible to identify the controller and flash inside the unit. As we can see from the photograph below, the Supersonic Rage 2 256GB is the smallest flash drive that we have evaluated in its capacity class. The design also supports hanging the flash drive off a keychain. There is also no need for an explicit cap on the USB connector. It still features a retractable USB connector, allowing for a compact design. In terms of external design and features, the Patriot Supersonic Rage 2 doesn't depart from the older members in its lineup. The list of flash drives used for comparison purposes in this review is provided below. Today, we will be looking at the performance of the Patriot Supersonic Rage 2 256GB, a high-end USB 3.0 flash drive sporting a recently introduced native USB 3.0 flash controller. Controller vendors have recently started to introduce native high-performance USB 3.0 flash controllers. However, this increases the drive cost in what is essentially a price-sensitive market. High-performance flash drives have traditionally employed a SATA SSD controller behind a USB 3.0 - SATA bridge. USB flash drives are a dime a dozen, but there is scope for manufacturers to differentiate themselves. The rise of USB 3.0 as a high speed interface for PCs and the increasing affordability of flash memory has led to some very interesting products.
