H2testw is described as 'Data integrity test for USB sticks and other media' and is a Benchmark tool in the os & utilities category. There are more than 10 alternatives to H2testw for Windows, Linux and Mac. The best H2testw alternative is HD Tune, which is free. Other great apps like H2testw are F3, USB Flash Drive Tester, Flash Memory Toolkit and ValiDrive.
HD Tune is a hard disk / SSD utility with many functions. It can be used to measure the drive's performance, scan for errors, check the health status (S.M.A.R.T.), securely erase all data and more!.
F3 is an open source command-line tool that assesses the real capacity of USB sticks and other media. An advantage over other tools is, that it does not need administrative rights to access the device.
Better than. Has same functionality (even can produce h2testw files) BUT HAS MORE. Probe facility to rapidly identify known fakes - much much quicker than h2testw. runs on macs as well as linux and doze. Open source. Brew designed to help learn techniques of fakery - if you are interested.
open source and being developed further
Flash card/drive tester allows testing of any removable media including SD, MMC, CF, USB flash pen drives for bad or unstable sectors. Especially useful for testing for fake sizes often seen on low quality USB pen drives.
Flash Memory Toolkit is a small package which has some very useful options like file recovery, benchmark and error scanning.
Quickly spot-check any USB mass storage drive for fraudulent deliberately missing storage.
Macrorit Disk Scanner is a third party disk surface portable tool for scan disk bad sectors which provides you with better options and better performance than Windows native disk scanner.
MediaTester can test any media (SD, microSD, USB thumbdrive, etc) and verify it stores the expected number of bytes. The testing method is similar to h2testw but MediaTester can detect fake or defective media much faster by performing quick reads as data is written.
Tests USB Flash drives and Flash memory SD cards to determine if they are fake (not full capacity). Much quicker than H2testw.
Tool to test a USB drive or memory card to find out if it's a fake. The tool performs a simple test to determine if the full capacity is usable or not. All it does is fill the volume with test data and verify if the data on the volume is correct.
Quick Disk Test fills a disk with test data and verifies that it can be read back without errors.
Very good linux alternative to hwtestw. Very similar app. Need to install default-jre.
Reads disk files or directories and stops on the first read error.
There are two versions: a command-line perl script and a Java GUI.
sdspeed is the only product that measure the read and write rate and testing every bit of your SD memory card you can trust with no "conflict of interest".
