If all you use this drive for is occasional backup AND you unplug it after each use (which is what Seagate marketting suggests) then ALL of this is irrelevant because the drive wont get enough use to park itself to death. I recommend always passing an APM 255 command to drives that run 24/7 and an APM 250 command to drives that run more than an hour a day. So even though the 5400RPM drive will inevitably last longer due to better thermal performance and less inertia when "banged around" eventually the loading ramp will fail and cause physical wear to the heads or the platter edge. Many of these 2.5" drives are rated at low as 100,000 load/unload cycles but some are rated as high as 1,000,000. This data cane be seen on the first page under load/unload count 0000000D (which is 13) for a drive that has only been powered on 5 times and has less than an hour of use.

To combat this, manufactures have introduced very aggressive head parking, which causes wear in other areas of the drive.

Samus - Tuesday, Auglink Personally I don't trust a 7200RPM drive "locked in a cage."ĥ400RPM drives are much less prone to thermal runaway when being hammered with a few TB of data over a short period, say, during an initial backup.

In the next section, we will take a look at the value-add features and provide some concluding remarks.

This is not the intended use-case for portable hard drives, but the results are just presented here for the sake of completeness Seagate Backup Plus Portable 4TB PCMark8 Storage Benchmarks (MBps) Results might appear low, but that is part of the workload characteristic. Note that the bandwidth number reported in the results don't involve idle time compression.

Usually, PC Mark 8 reports time to complete the trace, but the detailed log report has the read and write bandwidth figures which we present in our performance graphs. The command line version allows us to cherry-pick storage traces to run on a target drive. The storage workload involves games as well as multimedia editing applications. The internal disk temperature was only slightly more than 40 C even after more than 127 GB of writes and 127 GB of reads continuously.įor the second use-case, we take advantage of PC Mark 8's storage bench. The above benchmark run was also instrumented to record the drive temperature as well as instantaneous transfer rates during the process. Seagate Backup Plus Portable 4TB robocopy Benchmarks (MBps)

BR: 10.7 GB Blu-ray folder structure of the IDT Benchmark Blu-ray (the same that we use in our robocopy tests for NAS systems).

Videos: 16.1 GB collection of 244 videos (MP4 as well as MOVs) in 6 sub-folders.

Photos: 15.6 GB collection of 4320 photos (RAW as well as JPEGs) in 61 sub-folders.

In order to tackle the first real-life use-case, we created three test folders with the following characteristics: Prior to taking a look at the real-life benchmarks, we first check what ATTO and CrystalDiskMark have to report for the Backup Plus Portable 4TB drive. The minor usage scenario is importing files directly off the DAS into a multimedia editing program such as Adobe Photoshop. The most common usage scenario is transfer of large amounts of photos and videos to and from the unit. Our testing methodology for DAS units takes into consideration the usual use-case for such devices.

The full details of the reasoning behind choosing the above build components can be found here. Thanks to Asus and Corsair for the build components AnandTech DAS Testbed ConfigurationĪsus BW-16D1HT 16x Blu-ray Write (w/ M-Disc Support) One of the USB 3.0 ports hanging off the PCH was used to connect the unit. In order to evaluate the DAS aspect of the Backup Plus Portable, we utilized the testbed outlined in the table below to test the performance.

Mac users can also download a NTFS driver for their system, making the unit truly portable across multiple operating systems.

The root folder also had setup files that opened up the default browser for registering the device / downloading the value-add software (Lyve / Seagate Dashboard). The Backup Plus Portable 4TB drive came pre-formatted in NTFS.
