Synthetic Benchmarks

Various synthetic benchmarks are available to quickly evaluate the performance of direct-attached storage devices. Real-world performance testing often has to be a customized test. We present both varieties in this review, starting with the synthetic benchmarks in this section. Prior to covering those, we have a quick look at our testbed setup and testing methodology.

Testbed Setup and Testing Methodology

Evaluation of DAS units on Windows is done with the testbed outlined in the table below. For devices with a Thunderbolt 3 Type-C interface (such as the TEKQ Rapide that we are considering today), we utilize the Thunderbolt 3 port enabled by the Intel Alpine Ridge controller. It connects to the Z170 PCH via a PCIe 3.0 x4 link.

AnandTech DAS Testbed Configuration
Motherboard GIGABYTE Z170X-UD5 TH ATX
CPU Intel Core i5-6600K
Memory G.Skill Ripjaws 4 F4-2133C15-8GRR
32 GB ( 4x 8GB)
DDR4-2133 @ 15-15-15-35
OS Drive Samsung SM951 MZVPV256 NVMe 256 GB
SATA Devices Corsair Neutron XT SSD 480 GB
Intel SSD 730 Series 480 GB
Add-on Card None
Chassis Cooler Master HAF XB EVO
PSU Cooler Master V750 750 W
OS Windows 10 Pro x64
Thanks to Cooler Master, GIGABYTE, G.Skill and Intel for the build components

The full details of the reasoning behind choosing the above build components can be found here. The list of DAS units used for comparison purposes is provided below. Not all benchmarks are available for all units, as our testing has evolved over the years, and more than three years have passed since the LaCie Rugged Thunderbolt and the d2 Thunderbolt 2 - SSD were evaluated. It must also be kept in mind that those two devices were evaluated using the Thunderbolt 2 port from our Z97-based Haswell testbed.

  • TEKQ Rapide Thunderbolt 3 SSD 240GB (exFAT)
  • TEKQ Rapide Thunderbolt 3 SSD 240GB (NTFS)
  • LaCie Rugged Thunderbolt 500GB
  • LaCie d2 Thunderbolt 2 - SSD 128GB

Synthetic Benchmarks - ATTO and Crystal DiskMark

TEKQ claims read and write speeds of 2700 MBps and 1500 MBps respectively, and these are backed up by the ATTO benchmarks provided below. Unfortunately, these access traces are not very common in real-life scenarios.

Drive Performance Benchmarks - ATTO

CrystalDiskMark, despite being a canned benchmark, provides a better estimate of the performance range with a selected set of numbers. As evident from the screenshot below, the performance can dip to as low as 46 MBps for low queue-depth random accesses.

    Why the hell you didnt plug a samsung m.2 960 probto maje tests ? You need to plug a higher soeed ssd m.2 and test to see ir resch 2.5gbps of write and if drops soeed or not after filling and wrutw mant times the drives Reply

    So gt a 960 pro or 960 and plug into this rapide box and giveus test numbers, thats the real important thing for all guys, not the stupid default crappy phison slow m.2 unit Reply

    I would also love to buy just the box without the drive, heck pay a good premium for it too. Reply
