Yet another use of these synthetic benchmarks is the ability to gather information regarding support for specific storage device features that affect performance. The results translate to the instantaneous performance numbers that consumers can expect for specific workloads, but do not account for changes in behavior when the unit is subject to long-term conditioning and/or thermal throttling. Click Burn in iDVD and the PowerPoint presentations will be saved on the DVD as a video.Benchmarks such as ATTO and CrystalDiskMark help provide a quick look at the performance of the direct-attached storage device. Step 3: Insert a blank DVD into the Mac’s DVD drive.Follow these instructions to use the Format Painter:So there you go, various ways to share and edit PowerPoint files on your Mac, iPhone or iPad. You drag it over text to copy formats from one place to another. This nifty tool works something like a paintbrush.A simple, intuitive interface puts important tools front and center, so everyone on your team can easily add beautiful charts, edit photos, and incorporate cinematic effects. The performance is slightly behind the bridge solutions in terms of raw numbers.Keynote sets the stage for an impressive presentation. It does allow the visualization of change in transfer rates as the I/O size changes, with optimal performance being reached around 512 KB for a queue depth of 4. ATTO benchmarking is restricted to a single configuration in terms of queue depth, and is only representative of a small sub-set of real-world workloads. Tags:Kingston claims read and write speeds of 1000 MBps and 900 MBps respectively, and these are backed up by the ATTO benchmarks provided below - in fact, the numbers are actually higher than the claimed ones. Docx files on Mac, iPhone, and iPad.
![]() The 'Seq128K Q32T1' sequential traces use 128K block size with a queue depth of 32 from a single thread, while the '4K Q32T16' one does random 4K accesses with the same queue configuration, but from multiple threads. Internally, CrystalDiskMark uses the Microsoft DiskSpd storage testing tool. Two of the traces are sequential accesses, while two are 4K random accesses. For example, uses four different access traces for reads and writes over a configurable region size. In PowerPoint for Mac 2011, narration is not saved when you save a presentation as a movie.CrystalDiskMark. Powerpoint 2011 Copy Presentation To Thumbdrive Drivers On TheHowever, the benefits of a real SSD controller are evident in the high queue-depth random access performance, where the DT Max's performance is cut in half compared to the ASMedia bridge solution. This assumes that the host port / drivers on the PC support UASP.The sequential workloads' numbers are essentially the same for both the UFD and bridge solutions. If the numbers for the two access traces are in the same ballpark, NCQ / UASP is not supported. Comparing the '4K Q32T16' and '4K Q1T1' numbers can quickly tell us whether the storage device supports NCQ (native command queuing) / UASP (USB-attached SCSI protocol). The plain 'Rnd4K' one uses only a single queue and single thread. Home: Photos and document files totalling 18.86 GB over 7627 files in 382 sub-folders AV: Multimedia content with audio and video files totalling 24.03 GB over 1263 files in 109 sub-folders The evaluation involves processing five different workloads: Some users may even opt to boot an OS off an external storage device.The AnandTech DAS Suite tackles the first use-case. Other usage scenarios include the use of the unit as a download or install location for games and importing files directly from it 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. This process is repeated three times for each workload. Disk-to-Disk: Addition of 223.32 GB spread over 171 files in 29 sub-folders to the above four workloads (total of 317.91 GB over 9176 files in 535 sub-folders)Except for the 'Disk-to-Disk' workload, each data set is first placed in a 29GB RAM drive, and a robocopy command is issue to transfer it to the external storage unit (formatted in exFAT for flash-based units, and NTFS for HDD-based units).Robocopy /NP /MIR /NFL /J /NDL /MT:32 $SRC_PATH $DEST_PATHUpon completion of the transfer (write test), the contents from the unit are read back into the RAM drive (read test) after a 10 second idling interval. ISOs: OS installation files (ISOs) totalling 28.61 GB over 4 files in one folder It does include more amount of continuous data transfer in a single direction, as data that doesn't fit in the RAM drive is also part of the workload set.The workloads are processed in sequence, and the initial ones - particularly the read workloads - show great performance from the DT Max. The data is copied to the external unit from the CPU-attached NVMe drive, and then copied back to the internal drive. Bandwidth for each data set is computed as the average of all three passes.The 'Disk-to-Disk' workload involves a similar process, but with one iteration only. Whenever possible, the temperature of the external storage device is recorded during the idling intervals. Remote download wireless adapter netgear driverPerformance ConsistencyAspects influencing the performance consistency include SLC caching and thermal throttling / firmware caps on access rates to avoid overheating. To address this concern, we also instrumented our evaluation scheme for determining performance consistency. However, power users may want to dig deeper to understand the limits of each device. For all practical purposes, casual users will not notice the difference between them in the course of normal usage. Performance numbers are equivalent to what one might expect from bus-powered portable hard drives.As long as the workload is contained within the SLC cache (more on the sizing further down in this section), it can be seen that there is no significant gulf in the numbers between the different units. To avoid this problem, we have restricted ourselves to recording the temperature only during the idling intervals. However, we have observed that SMART read-outs for the temperature in NVMe SSDs using USB 3.2 Gen 2 bridge chips end up negatively affecting the actual transfer rates. In earlier reviews, we used to track the temperature all through. Finally, we have the single disk-to-disk transfer set. This is followed up with the large-sized ISO files set. Another small RAM-drive transfer gap is followed by three sets for the Blu-ray folder. A small gap (for the transfer of the video suite from the internal SSD to the RAM drive) is followed by three sets for the Home suite. Examples include booting an operating system or loading a particular game from the disk.PCMark 10's storage bench (introduced in v) includes four storage benchmarks that use relevant real-world traces from popular applications and common tasks to fully test the performance of the latest modern drives: Real-world access traces may be used for simulating the behavior of computing activities that are limited by storage performance. More serious benchmarks, however, actually replicate access traces from real-world workloads to determine the suitability of a particular device for a particular workload. We saw results from two popular ones - ATTO, and CrystalDiskMark - in a previous section. PCMark 10 Storage Bench - Real-World Access TracesThere are a number of storage benchmarks that can subject a device to artificial access traces by varying the mix of reads and writes, the access block sizes, and the queue depth / number of outstanding data requests. Once the cache is out, the performance goes down from close to 1GBps to around 80 MBps. It subjects the device to 23 GB of writes. The Quick System Drive Benchmark is a shorter test with a smaller set of less demanding real-world traces. It involves a total of 204 GB of write traffic. The Drive Performance Consistency Test is a long-running and extremely demanding test with a heavy, continuous load for expert users. The device is subjected to 15 GB of writes. These typically include NAS drives, USB sticks, memory cards, and other external storage devices. These types of use-cases are addressed only in the full system drive benchmark.The Full System Drive Benchmark comprises of 23 different traces. Many of us use portable flash drives as boot drives and storage for Steam games. This writes more than 23 TB of data to the drive.Despite the data drive benchmark appearing most suitable for testing direct-attached storage, we opt to run the full system drive benchmark as part of our evaluation flow. ![]()
