Review on 💾 WD Western Digital 2TB 2.5" 128MB SATA III Hard Drive for Laptops, PS4: Faster & Reliable Storage Solution by Kichiro Norimatsu ᠌

There was an idea to make an external drive myself from a low consumption internal drive and a USB 3.0 enclosure. It turned out that after a long recording of data in random sectors, the disk in the background starts to overwrite something itself. These are the very grunts that other users are talking about. This behavior significantly affects not only the further speed of SEQUENTIAL writing, but also, as I remember now, even reading (the latter is not observed with other disks). Apparently, this is how the tiled recording (SMR) technology is implemented in this disc, forcing the disc to overwrite tracks superimposed on each other. Within 10-15 minutes. This technology is currently used by at least ALL laptop and external drives with a capacity of 2 TB or more (which is very sad). As a result, it is not comfortable to use modern disks for any tasks for which you have to write a lot to different areas of the disk: downloading torrents, writing many small and medium files. Also, sooner or later there will be high fragmentation on the disk and subsequent recording on it will become problematic. And defragmentation will become almost impossible - after all, this is the recording of a bunch of data in different areas of the disk. Probably their only use is to write large files infrequently and then read them frequently (for example, movies). I hope that the firmware and the disks themselves will be finished soon (if possible). Before the drive is completely overwritten for the first time, it will show an artificial read speed of 250 MB / s over SATA-II. Sequential read speed (at the beginning of the disk, in the middle, at the end and average, respectively): 120 MB / s, 95 MB / s, 55-119 MB / s and 94.8 MB / s. Sequential write speed: 118MB/s, 95MB/s, 57-118MB/s Sequential write speed after activating SMR background overwrite from 6 MB/s to 44 MB/s, average about 18 MB/s. I returned this drive and took the risk of taking the TOSHIBA L200 HDWL120EZSTA into a laptop, without an external case.
