WD Black˛ Dual Drive Review - The Benchmarks (I)

The Comparison Drives:
1. Sandisk Extreme 120GB 2.5in SDSSDDX120GG25
2. WD Caviar Blue 500GB 3.5in WD5000AAKX-00ERMA0
3. Toshiba 750GB 2.5in MK7575GSX
4. WD Black˛ Dual Drive 2.5in WD1001X06X-OOSJVT0



*Note. Full SATA 3 speeds are not attainable with mechanical hard drives. Both WDC Blue and the Toshiba 750GB are tested using SATA 2 connections. Even the mechanical drive of the WD Black˛ is under this limit even if connected to a SATA 3 port. AHCI Mode is enabled through the BIOS.



Now we head on the numbers.

Anvil's Storage Utilities 1.1.0.337
Download Link

Anvil's Storage Utilities is a powerful tool that was designed in order to provide users with a simple means of assessing the read and write performance of SSD or HDD. The tests were done using the default settings and with a 1GB test size.



The Read Score of the WD Black˛ SSD is a few points higher compared to the SanDisk SSD. The Write Score of the SanDisk SSD however is around 43% higher than the WD Black˛ SSD. The Read Scores of the Toshiba HDD 5400RPM and the WDC Blue HDD are just a few points in difference but had a 28% advantage for the WDC Blue in Write Score thanks to its 7200RPM speed. The WD Black˛ HDD side is impressive, which came out on top of the mechanical HDD comparisons even if it only spins at a speed of 5400RPM.


AS SSD Benchmark 1.7.4739.38088
Download Link

Testing the sequential or random read/write performance without using the cache, AS SSD Benchmark reads/writes a 1 GB file as well as randomly chosen 4K blocks and additionally performs the tests using 1 or 64 threads and it determines the SSD's access time.



The WDC Blue scored only few points higher over the 5400 Toshiba HDD. The WD Black˛ HDD once again reigned better than the rest of the mechanical hard drives in Read and Total Scores. The WD Black˛ SSD won over the SanDisk SSD in these tests either be it in read or write and in total score which obtained 33%, 11.5%, and 28% advantages respectively.


ATTO Disk Benchmark 2.47
Download Link

ATTO is one of the oldest drive benchmarks still being used today and is still very relevant in the SSD world. ATTO measures transfers across a specific volume length. It measures raw transfer rates for both reads and writes and places the data into graphs that can be very easily interpreted. The test was run with the default runs of 4096kb through 4196kb transfer sizes with the total length being 256mb.



As expected, the Toshiba HDD is slower compared to the WDC Blue, but the WD Black˛ HDD is beating the WDC Blue by 15% in Read speeds and by 16% in Write speeds. The 4K test ruled out the 29% Read speed and 71% Write speed advantage of the SanDisk SSD over the WD Black˛ SSD. Yet the scores of the WD Black˛ SSD are to be appreciated, running past its specified transfer rates.


CrystalDiskMark 3.03b
Download Link

CrystalDiskMark is a disk benchmark utility that measures performance for sequential and random reads/writes of various sizes for any storage device. It is useful for comparing the speed of both portable and local storage devices.



The Toshiba HDD only gained advantage in the 512K Write field against the WDC Blue. The WD Black˛ HDD on the other hand outscored the WDC Blue in every field except for the 0.051 MB/s loss in the 4K Read. Good scores once again for the WD Black˛ HDD against the mechanical drives. The SanDisk SSD excelled only by 47MB/s in Sequential Read and 1.7MB/s in 512K Read along with 18.12MB/s advantage in 4K Write against the WD Black˛ SSD. An impressive speed scores across the chart for the WD Black˛ SSD.


DiskBench 2.6.2.1
Download Link

Most of them run a single specific test that often doesn't tell you much about how your disks perform in a real-world situation, such as copying large files and even whole directories. Disk Bench is a free benchmarking tool that lets you choose which files or folders to copy. It then copies the data, benchmarks the speed, and deletes the copied data from the destination, though you can also keep the copied data. It also creates test files with a repeating 128-byte string, which is a preferred method for benchmarking a single disk, as well as batch files for testing. The Copy Directory was used with mixed data of 3.96GB in size. The Read file was used with a 148MB.



Having the real world tests of DiskBench, the Toshiba HDD still showed inferiority in read speed over the WDC Blue, especially in write speeds. The WD Black˛ HDD on the other hand still maintained to beat the WDC Blue by a few points in read and write tests. The WD Black˛ SSD maintained to stay close to the SanDisk SSD in terms of Read speed and gained advantage of around 10% in write speed.


HD Tune Pro 5.5
DownLoad Link

HD Tune Pro is a hard disk / SSD utility with many functions. It can be used to measure the drive's performance, scan for errors, check the health status (S.M.A.R.T.), securely erase all data and much more.



Using the File Benchmark tab of HD Tune Pro, the Toshiba HDD showed lower read speed and gained a very minimal 515KB/s over the WDC Blue. The WD Black˛ HDD Still stood with high read speed against the mechanical drives and lost around 13% in write speed. The WD Black˛ SSD performed close to specifications having around 340.6MB/s and 146.9MB/s read and write speeds respectively. The SanDisk SSD on the other hand plunged below specifications and ran only at 406.4MB/s read and 155.8MB/s write speed.


Passmark Version 7
Download Link

PassMark Software has delved into the thousands of benchmark results that PerformanceTest users have posted to its web site and produced charts to help compare the relative performance of different hard drive models with storage capacities from gigabyte to terabytes. The charts include results from many major hard drive manufacturers, including but (not limited to) Seagate, Western Digital (WDC), Hitachi, Maxtor and Samsung. Our data can help you assess the performance of your hard disk drive (HDD) in comparison to similar models, or help users decide whether newer hard drive technologies represent good value for purchasing when it comes to high performing data storage and retrieval.



In here we still see a good consistency in performance from the WD Black˛ HDD over the WDC Blue and Toshiba HDD. The WD Black˛ on the other hand stood firm in its specified write speed against the SanDisk SSD but got only around 16% of the SanDisk’s speed in the Random Seek + RW test and only 51% of the Sandisk’s read speed.
