Review on High-Performance Enterprise HDD: WD Gold WD101KRYZ 10TB SATA 6Gb/s 7200 RPM by Jnis ubars ᠌

But don't crystal brands and so on lie, giving out average speeds according to tests? I checked it in Victoria v 4.47Rus, having received the first results, put the harddisk on the foam rubber, screwed a 50mm fan from below (also through the foam rubber) - special cooling for hard drives (since the controller still heats up) and in such ideal conditions (32 degrees, there are no vibrations) - 1) 4 surface tests in Victoria in a row showed from 300 to 600 "green" sectors (!) with a read delay of up to 120ms For comparison - the same test for wd red 3 tb shows 1 -2! green sectors for all 3 TB! But a long recheck showed that all the green sectors each time in a new place. there are no repetitions in the same sectors. Otherwise, I would have decided that the disk is starting to crumble and ran to take it. 2) SPEED of reading in Victoria during the surface test. looks like this - first 50 seconds 200-210 mb sec, cool! then . 60 seconds of speed 120-130 mb sec. again 50 seconds shows a speed of 195-200 mb / sec, . and long dips of 130-120 mb sec went. Throughout the first 400 GB. I even thought that I should first cram any 400 GB files onto the disk, and only after, when the slow sectors are over, and put the system so that it stands next to the sectors. So the entire surface test speed jumped like a seismograph during an earthquake - 60 seconds at a speed of 120-130, then 45-50 seconds of the test goes at a speed of 180-190 mb / s. + many intervals with a speed of 140-150 mb/sec. very uneven schedule. Tests with 7sp1, everything is unloaded from memory, only clean Windows and Victoria with the test. without swap, 16g of RAM, i7 4.3GHz, top-end mother under cooling. That is, it remains only to sin on the controller of the gold disk. Wd red has a much smoother graph, almost a diagonal line. His reading speed will be constant. 2 screenshots of Victoria tests:
