They're more expensive, but a lot faster. That's when an SSD is the smart option over an external hard drive. Speed can be of the essence if you have gigabytes of big image or video files and don't want to be stuck watching the progress bar crawl along at a glacial pace. The best external hard drives and best external SSDs If you're looking for more accessories, you might also want to take a look at our pick of the best power banks and the best internal hard drives. If you're looking for a device specifically for gaming, see our guide to the best SSD for PS5, and remember you can also back up files with the best cloud storage. See how we test and review for more on our process. Based on our own experience and thousands of customer reviews, as well as reputation, we whittled the options down to these stellar choices. So what made our list, and why? We've considered price, storage capacity, upload speed and connectivity – crucial specs for hard drives and SSDs.

If you're not sure how to choose between them, skip down the page to our section on how to choose the best external hard drives. So to make it easier for you to pick the best external hard drive or the best external SSDs for you, we've chosen a selection of our favourite options for both PCs and Macs. The program measures operation time.You'll need to store, share, transfer and back up files and assets easily, efficiently and safely, and it's likely that you won't want to spend more money than you need. Test ends in the middle of the testing area. The first block in the first pair will be Block 0, the second block in the first pair will be Block N (where N is number of last block for testing).

  • Butterfly Read mode is similar to Read mode difference only in blocks' order.
  • The program tests blocks one by one from minimum to maximum. The program sends the block of data to the drive and the drive writes the block (All previous data in the block on the drive will be overwritten with the pattern and cannot be recovered after that!) The program measures operation time for each block.
  • In Erase mode the program prepares block of data field with special pattern and an LBA number.

    The program reads block of data into a temporary buffer and measures time of operation for each block. In Read mode device reads block of data and transfers it thorough interface to the host controller.The program measures operation time for each block. In Verify mode device reads block of data into drive's internal buffer only and checks for consistency, there is no data transfer through an interface connector/cable.Verify test may work in unreliable way on USB/Flash devices.

  • Verify test may have restrictions on Block Size with 256, 16384 or 65536 sectors because of Windows limitations.
  • Author wasn't able to get stable test results with two or more simultaneous tests.
  • The program should not be run from a read-only device/media.
  • Windows XP SP3, Windows Server 2003 (with restrictions), Windows Vista, Windows 7, Windows 8, Windows 10.
  • Spindle start/stop function on ATA/SATA/USB/FireWire/SCSI HDD.

  • Reporting defect information on SCSI HDD.
  • Changing AAM, APM, PM parameters on ATA/SATA/USB/FireWire HDD.
  • Reading and analyzing identity information from ATA/SATA/USB/FireWire/SCSI HDD.
  • Temperature monitor for ATA/SATA/USB/FireWire/SCSI HDD.
  • SMART tests running on ATA/SATA/USB/FireWire HDD.
  • Reading and analyzing Log Pages from SCSI HDD.
  • Reading and analyzing SMART parameters from ATA/SATA/USB/FireWire HDD.
  • Reading in Butterfly mode (synthetic random read).
  • USB BACKUP HARDDRIVE VERIFICATION

    Reading in linear mode – same as verification but also transfers data to the host.Verification in linear mode – fastest way to determine if your drive needs data rescue, has recoverable errors or in its perfect shape.USB Flash (pen drives) – surface tests only.

  • RAID volumes made of ATA (IDE) / SATA / SCSI HDDs (surface tests only).
  • FireWire or IEEE 1394 HDD (see Appendix A).
  • External USB drives and all major USB boxes (see Appendix A).
