Usb img burner diskmark7/7/2023 ![]() ![]() Why do they perform so much worse in this benchmark? Thermals The Arcanite was only a tiny bit slower than the SSDs and the Corsair in the quick sequential tests, and the Ultra Fit was actually slightly faster than the Ultra Flair. The Arcanite and the SanDisk Ultra Fit perform much worse for long-duration file copies than all the rest. I believe that the scale should be 'Mbps', but I need to go back to my data and verify what exactly was measured, and re-generate the graph below. This test doesn't sustain the maximum sequential throughput for the drive, but it does take a long time and tests how well the different devices handle heat from constant write activity. And the Corsair GTX is by far the fastest USB flash drive I've ever tested.īut there's one other test I wanted to do before closing the book on performance, and that's a 10 GB file copy over the network. So overall, it looks like a decent quality NVMe drive and USB enclosure is going to give the best overall performance. And the XPG NMVe drive is at least twice as fast as every other option when it comes to random write performance. The performance of the older flash drives remains abysmal, with even the microSD card trouncing them in random 4K write performance.īut the Arcanite also falls off quite a bit in comparison to the SSDs and the Corsair. Random IO performance paints a more complex picture. The Arcanite does well here, but it does lag a little bit behind the SSDs and even the Corsair GTX. The sequential results show a huge gap between the SSDs and fast new USB flash drives and the cheaper older-generation flash drives and the microSD card.įrom what I've found, it seems like most USB flash drives perform the same as a microSD card in a USB adapter: So how did all these drives perform? I ran all the tests booting the Pi from the device that was being tested, and I also ran the same benchmarks on my fastest microSD card, a Samsung Evo Plus. I ran benchmarks on every one of these drives, testing their sequential read and write performance with hdparm and dd (to test large file operations), as well as their random 4K read and write performance with iozone (to test more general usage patterns when booting or running apps on a Pi). ![]() (Inside the Raspberry Pi) Samsung Evo Plus 32GB microSD card. ![]() SanDisk Ultra Fit 128GB USB 3.0 flash drive.SanDisk Ultra Flair 16GB USB 3.0 flash drive.Corsair Flash Voyager GTX 128GB flash drive.TDBT M.2 NVMe Enclosure and XPG SX6000 Lite 128GB.Inatech SATA enclosure w/ UASP and Kingston 120 GB SSD.I added a couple other drives to the test, pictured below:Ĭlockwise, from the Inateck case in the top middle: The interface is clear and clean, and multiple configuration options allow you to view what you need anytime, anywhere.So I took Rob up on the offer, and he sent me an XPG NVMe drive in a TDBT enclosure and an Arcanite AK58 USB 3.1 flash drive, touted by some as 'one of the fastest USB flash drives available'. From its dashboard, you can quickly view a long list of the latest system data, so you can know when things are going well and if there are problems.ĬrystalDiskInfo is a good free choice, if you have good computer knowledge and want to keep abreast of the latest developments in the system. Generally speaking, once a drive starts to crash, it quickly goes downhill, so if you start to see an increase in failure rates, it is usually best to assume the worst.ĬrystalDiskInfo provides you with all computer SMART information and complete readings of current temperature and health status. When various factors approach the critical threshold, CrystalDiskInfo will remind you that it is time for a backup. This includes details such as the current drive temperature, the number of failed read or write attempts, how long the drive has been running, and how often it is started and stopped. ![]() Most hard disks are included in the recent system and may appear to tell you the disk status.
