The performance numbers show that the My Passport 4TB performs better than the LaCie Porsche Design Mobile Drive 4TB for reads, while the situation is reversed for writes (which is similar to the behavior we encountered in the CrystalDiskMark traces). The same procedure is adopted for the Videos and the BR folders. This process is repeated thrice and the average of all the runs is recorded as the performance number. The segments end with the purge of the contents from the storage device.

The first segment gives the write speed, while the second one gives the read speed for the storage device. robocopy is again used to transfer the content, but, from the storage drive under test to the RAM drive. The content on the RAM drive is then deleted. robocopy is used with default arguments to mirror it onto the storage drive under test. The test starts off with the Photos folder in a RAM drive in the testbed.

The 'Seq Q32T1' sequential traces use 128K block size with a queue depth of 32 from a single thread, while the '4K Q32T1' ones do random 4K accesses with the same queue and thread configurations. Internally, CrystalDiskMark uses the Microsoft DiskSpd storage testing tool. Two of the traces are sequential accesses, while two are 4K rando accesses. Real-world performance testing is done with our custom test suite involving robocopy bencharks and PCMark 8's storage bench.ĬrystalDiskMark uses four different access traces for reads and writes over a configurable region size. CrystalDiskMark is used for a quick performance overview. You'll get around 150MB/s for reads and writes, which isn't particularly peppy (compared to an SSD), but it's a lot of space to potentially back up multiple PCs.Our evaluation routine for hard-drive based direct-attached storage devices borrows heavily from the testing methodology for flash-based direct-attached storage devices.

If you can no longer access your data, Seagate will attempt to retrieve it for you.Īs for the drive itself, it's an 8TB HDD stuffed into a portable enclosure with a USB 3.0 interface. It doesn't matter how your drive died, either, whether it's a mechanical failure, an accident on your part, or a natural disaster like a flood. Seagate says its in-house data recovery service boasts a 95% success rate, but in the event it can't recover your files, Seagate will either "destroy your drive in a secure and environmentally friendly manner or return it" to you, whichever you prefer. The turnaround time is up to 15 business days. Seagate even hooks you up with a prepaid shipping label. The way it works is, if the drive goes belly up for any reason while under warranty, you can file a claim to have a team of pros try and extract your data. Rescue Data Recovery Services is a big value addition here.
