Introduction

The benchmark tests are based on those produced for Windows, where details and results can be found in DiskGraf Results.htm and CDDVDSpd Results.htm. Virtually the same tests are used in Linux Disk, USB and LAN Benchmarks. and a subset in An Android Version. The tests comprise:

  • Writing and Reading Large Files - Five files each of 8 MB, 16 MB and 32 MB are used.
    System is instructed not to cache the data.


  • Writing and Reading Cached Data - Five files of 8 MB are used. Performance normally
    reflects memory speed.


  • Reading Bus Speed - The same data is read repetitively at block sizes between 64 KB and
    1 MB. This normally reads data from the disk’s buffer to show maximum bus speeds.


  • Random Reading and Writing Speed - 1 KB blocks are read and written randomly from 7
    file sizes between 2 MB and 128 MB. Results reflect the disk's buffer size and rotation speed.


  • Writing and Reading Small Files - 500 files are written, read and deleted at 6 different
    file sizes each between 2 KB and 64 KB. Besides speed, milliseconds per file is provided
    to reflect overheads.


The execution file is drivespeed32.exe. This and source code, along with compiling and running instructions, can be downloaded in drivespeed32.zip. The benchmarks are simple execution files and do not need installing. Details are displayed when the tests are running and performance results are saved in log file IOspeed.txt. Drivespeed32.exe should be copied to the disk/partition to be tested and is also appropriate for measuring speed of devices on USB or networks. Following is an example of log file results.

Drive and Bus MB/Second - Large Files

The PC main disk drive is slightly faster using the inner partition C: for Windows, but see later results for small files. Compared with older drives, at over 500 MB/second, the measured bus speed reflect the 6G bits/ second specification. Overall performance is better than the other devices shown.

Speed of this particular SSD is not that good but the bus speed results (rereading the same block) suggest a bus faster than SATA 3 (PCIe?).

SDex USB 3 Flash Drive maximum reading and writing speeds are a little faster than the specifications, with MSDE MicroSDHC card reflecting that for reading, but both fall down on average performance on writing. The disk drive higher cached writing speeds suggest deferred write back, as opposed to USB 3 devices with settings “optimised for quick removal”. Typical USB 2 results are shown, where USB 3 is up to six times faster.

Random Read milliseconds

Disk drives can have faster random access times than Flash drives, at smaller block sizes, where data fits in the disk’s buffer. With data larger than this, minimum average access time is likely to be that for half a revolution, or 4.17 milliseconds at 7200 RPM (HD D: 64 MB buffer with some hits) and 5.56 milliseconds at 5400 RPM (HDS1 16 MB?). USB 3 can be more than twice as fast as USB 2, where data is read from the buffer.

SSD random reading time is better than 0.005 milliseconds, with all data cached and that fast bus.

Random reading can be a lot slower on older USB Flash Drives and fairly constant on later devices, over the file sizes used here. FAT and NTFS response times can be similar. USB 3 speeds are only 50% faster than via USB 2, at the smaller file sizes.

Random Write milliseconds

Random writing times on disk drives is slower and more variable than random reading. In this case, USB 3 can be more than three times faster than USB 2, with the smaller files.

SSD random writing times are the fastest.

The variability can lead to USB 2 appearing to be faster than USB 3 and FAT formatting better than NTFS.

500 Files Write milliseconds and Delete seconds

Writing numerous small files can identify significant performance differences. It frequently shows that there is a larger overhead when writing to the disk partition containing Windows. In the case of the USB disk, writing time via USB 3 is two to three times faster than USB 2.

The SSD performance is not outstanding at all file sizes.

It was this area where FAT formatting could be unacceptably slow, on older USB sticks but, on the latest Flash Drives, performance can be close or even faster, where speed in inconsistent.

500 Files Read milliseconds

The disk drive on Ci7-2 is again much slower reading small files from the Windows partition. As on writing, the USB disk is two to three times faster via a USB 3 port.

For some reason, the SSD is slow on this section of tests.

FAT formatting, via USB 3, appears to be faster than using NTFS, where USB 3 is shown to be up to six times faster than USB 2.

Drive and Bus MB/Second - Large Files

SATA and PATA Disks - Most of the disk drives are in PCs from the same supplier, indicating maximum data transfer speed increases of more than three times, over 7 years. These disks mainly have more than one partition where, as expected, later partitions, with less data per track, are generally shown to be slower (but see small files).

With caching, the older Operating Systems appear to be slower on writing, later ones probably using deferred lazy writing to update disks over a period. In other cases, and with cached reading, performance depends on memory speed, best being Ci7-2 with four channels. The latter also had 6 Gb/s SATA ports, compared with 3 Gb/s on the others, providing greater than 520 GB/second.

USB Disks - USB 2 performance is dependent on bus speed, in this case, different hardware and software having little impact. For these drives, cached writing does not appear to be supported (appropriate for plugged in devices). USB 2 (High Speed) is rated as 480 Mb/s or 60 MB/s and USB 3.0 as 5 Gb/s or 625 MB/s. Measured USB 3 speeds were not too close to this 10.4 times difference, but 3 to 4 times with data to/from the disk surface or 6.8 times from the disk’s buffer.

Asus USB 3 Boost Option - This is an option selected via Asus AI Suite II. In this area, the only improvement was in the bus speed test, producing 277 MB/second (but see small files).

Random Read milliseconds

SATA and PATA Disks - Random access time, for the file sizes used here, normally depend on the size of the disk’s buffer (mainly 16 MB, Ci7-2 64 MB), half disk rotation time (4.17 milliseconds at 7200 RPM and 5.56 at 5400 RPM) plus bus or disk data transfer speed (Ci7-2 fastest and disk HDX slowest - see bus speed above). Netbook NB1 is slower than expected.

USB Disks - These have the added overhead of slower data transfer speed. USB 3 provides some improvement when data is in the buffer.

Asus USB 3 Boost Option - This has little effect with random access.

Random Write milliseconds

There is more variability on random writing, compared with reading, but access times appear to be lower when data transfer is not from the disk’s buffer, then higher when cached there. As with random reading, USB 3 can be somewhat faster.

500 Files Write milliseconds and Delete seconds

SATA and PATA Disks - There are variations, but average writing times can be fairly constant at all the file sizes used on a particular configuration. Partitioned drive results are particularly of interest where, except for Netbook NB1, with XP, file writing times are considerably longer using the C: Windows partition.

USB Disks - The same drive with FAT formatting is somewhat slower than using NTFS but not as significant using the Core i7 PC. The latter also appears to be more efficient using NTFS. USB 3 results are around 2.2 times faster with the smallest files, increasing to nearly three times at 64 KB.

Asus USB 3 Boost Option - In this case, the UASP protocol used produced severely degraded performance, with an average of greater than 20 milliseconds per file and deleting time of 6 seconds.

500 Files Read milliseconds

SATA and PATA Disks - Even with Netbook NB1, reading speeds are significantly slower using a C: Windows partition.

USB Disks - Unlike on writing, reading speeds with NTFS formatting are much slower than with FAT. USB 3 file reading times are 2 to 3 times faster than via USB 2.

Asus USB 3 Boost Option - UASP appears to have no effect on reading speed of small files.

Drive and Bus MB/Second - Large Files

SSD Drives - The only result available does not demonstrate particularly fast speeds on writing and reading large files, but bus reading speed is exceptionally fast. As a reminder, this test rereads the same block to measure speeds from a disk’s buffer. For this particular device, the high speeds were consistent up to the maximum block size used of 1 MB. indicating a much larger cache than on disk drives.

USB 2 Sticks and SD Cards - NTFS and FAT formatting has little effect of writing and reading large files and speed is fairly consistent using different PCs, USB 2 speed and the age of the technology are the limiting factors.

USB 3 - The SanDisk Extreme USB 3.0 Flash Drive appears to produce higher maximum speeds than the specification, and can be much faster than disk drive HDS1 (see above), but wide variations lead to lower average writing speeds. Reading speeds are up to eight times faster than usins a USB 2 connection.

The inexpensive USB 3 card reader performs well with the 16 GB San Disk microSDHC Extreme Pro card, at up to five times faster than via USB 2.

Random Read milliseconds

SSD Drives - Compared with other devices, the SSD random reading speed appears to be impossible. However, the process reads 1 KB blocks out of up to 128 MB and the SSD may well have a 256 MB cache feeding a 6 Gb/s bus, making the impossible possible at less than 0.005 milliseconds per access.

USB 2 Sticks and SD Cards - Access times of the smaller files are similar to USB 2 disk drives, but continue at constant values using larger files, where disks have buffer size limitations. Typically, FAT and NTFS formatting, or the age of the device, make no difference except, perhaps, on the later SDex device, where NTFS appears to be faster.

Using PC built-in readers, the SD cards tested were slower than USB 2 sticks and FAT formatting could be somewhat faster than NTFS.

USB 3 - The SanDisk Extreme USB 3.0 Flash stick is mainly 50% than via USB 2. The 16 GB San Disk microSDHC card provides fewer gains via the USB 3 reader.

Random Write milliseconds

SSD Drives - Random writing time from small files is similar to that for the USB 3 disk drive above, but much faster accessing larger files.

USB 2 Sticks and SD Cards - Note the slow speeds on the older USB stick and SD card, with improvement on the later devices. There are extremely wide variations on the Pat drive but some suggestion that performance is better using FAT format. Then, NTFS might have the edge on SDex.

USB 3 - Average USB 3 speed is 20% faster than using USB 2.

500 Files Write milliseconds and Delete seconds

SSD Drives - Average time to write files is by far the fastest, in this section, but similar to disk drive HDS1 on USB 3 above, with the smallest ones.

USB 2 Sticks and SD Cards - Again note the slow speeds on the oldest device, where FAT formatting is much slower than NTFS and file deletion time significantly longer. This is due to the unavailability of the option to optimise for performance and involves frequent updating of the File Allocation Table to enable “safe to remove”. With later devices, FAT appears to be sometimes faster.

USB 3 - Speeds are quite variable, but the average USB 3 speed gains for FAT/NTFS are 2.1/1.8 for the USB stick and 1.8/1.6 with the SD card.

SSD Drives - Reading speed of small files is not as fast as some of the SATA disk drives, nor some of the USB sticks.

USB 2 Sticks and SD Cards - FAT or NTFS format can produce similar reading speeds, later devices are somewhat faster and the CPU type/speed seems to make a difference.

USB 3 - USB 3 provides a performance gain of 2 to 3 times over USB 2.
