TRIMįor a solid state disk (SSD), when using the drive without TRIM support over a longer period of time, the performance could be reduced. The SATA-III interface, also known as SATA 3 or SATA 6B/s interface limits the transfer rate to about 550 MB/s. SATA-III SSDĪ solid state disk (SSD), at least with most models nowadays, can usually reach the limit of the SATA-III interface. You can stripe multiple drives to achieve faster speeds but in most cases, the bottleneck will be the drive itself. SATA HDDĪ hard disk drive (HDD) uses one ore more rotating disks (platters) and due to the way the data is stored and accessed, such a drive is usually limited to a transfer rate of about 100-200 MB/s. In addition, there are certain limitations depending on the type of drive and its interface. The transfer speed can vary a lot depending on the drive model, even if it's the same type of drive, so it's always a good idea to check the specifications first and if possible, refer to an actual test result with that particular drive. Hard Disk Drives (HDD) and Solid State Drives (SSD) To better understand what might be slowing down your drive and how you can improve the data transfer rate to get better speeds, we will look at each of the components separately. Second: This value is very plausible, as I don't expect the H264 encoder in the GPU and/or the H264 decoder in the Quest can handle much higher bitrates.In this article, we are going to identify the bottleneck of external storage drives and attempt to get the best possible data transfer speed out of your Akitio product. If you don't even know this difference, I wonder how you start a discussion. Youtube compresses FHD somwhere beolow 5 MBit/s. At the maximum configuration in the Oculus Debug tool its a 2912x16xx side by side image.Įven in Virtual Deskop with its 35 MBit/s at max and compressed to HEVC (h264 is another story at this bitrate) the onliest difference I can see is 4:2:0 of VD vs. You can see the usage of the encoder, when you look at the right place in the Windows Task manager.Īnd its not 2 times FHD. And it's not 'Youtube FHD' (which is compressed as f*ck, to the point that 1080p is actually closer to real 720p), it's real FHD.Ĭompressed into a H264 stream by the hardware encoder of the GPU. We're talking about a 75 Hz FHD 3D video stream. But I don't need it to be sure that your figures are wrong.
