#WD EASYSTORE SOFTWARE REVIEW REDDIT PORTABLE#High performance Micro USB 3.0 cable connects a portable external USB 3.0 hard drive to a computer for speedy file transfer or syncs and charges Samsung smartphones or tablets equipped with the USB 3.0 Micro-B port. “As with every Western Digital product, our product details, which include power, acoustics and performance (data transfer rate), are tested to meet the specifications provided on the product’s data sheet and marketing collateral.”ī&F thinks this is effectively saying WD has taken a 7200rpm platform and presented it as a 5400 rpm performance class drive. By doing so, we are able to leverage our economies of scale and pass along those savings to our customers. “We also fine-tune select hard drive platforms and the related HDD characteristics to create several different variations of such platforms to meet different market or application needs. We asked WD to comment and a spokesperson said: ‘“For select products, Western Digital has published RPM speed within a “class” or “performance class” for numerous years rather than publishing specific spindle speeds. Despite being classed by WD as a 5400 rpm drive its acoustic pattern is the same as 7200 rpm drives. There is differentiation between 7200 rpm and 5400 rpm drives until the WD Elements 8TB drive’s acoustic pattern is displayed. Here’s the pattern for a Seagate 4TB 5400rpm drive Ī Western Digital 1TB Blue 5400 rpm drive:Ī Western Digital Elements 8TB drive classed as 5400 rpm: ”Īnother poster has put up acoustic profile images on the thread, comparing the acoustic startup patterns for 7200 rpm and 5400 rpm drives. For 5400RPM this would be multiples of 90Hz instead (180Hz, 270Hz, 360Hz. If you have a disk spinning at 7200RPM (7200/minute = 120/second = 120Hz) then resulting vibrations will be at this base frequency or integer multiples (overtones) of it (120Hz, 240Hz, 360Hz, …). U/sbif writes: “The direct way to measure rotational speed is via the acoustic frequency profile.
