How do we test?
Testenvironment
We recommend that readers who aren't interested in test procedures, jump over the following page and head directly to the test results.| Model | Western Digital WD300BLFS | 300 GByte |
| Motherboard | Gigabyte X38-DQ6 | |
| Chipset | Intel X38 | 1066 MHz |
| CPU | Intel Xeon 3060 | 2.4 GHz |
| Memory | Corsair Dominator 9136 DDR2 | 2 GByte |
| Graphics card | Gigabyte GeForce 7200 | |
| Storage (system) | Maxtor | 160 GByte |
| Operating systems | Ubuntu 8.10 Hardy | Kernel 2.6.27-11-server |
| Filesystem | XFS |
We think everybody reading this article can imagine the following scenario: You just bought a hard drive, which according the specs sheet should transfer 120 MByte/s reading and writing. In the reviews you read about astonishing 110 MByte/s but after you put the drive into your system it feels much slower. The whole story gets even worse when you start a benchmark which does random read/write of 4 KByte blocks. There you only get two to three MBytes/s.
Because of this we don't want to publish screenshots of standard programs like HD-Tach, HD-Tune, ... we want our tests to be
- reproducible,
- accurate
- meaningful and
- varied
We test with activated caches and NCQ (Native Command Queueing) because they're also activated in daily use condition. The amount of data when the drive is tested is at least twice as much as the amount of memory in the testsystem.
We noticed that the measuring error is constantly within ±2%. Therefore we mention it only here.
Additionally we evaluate the S.M.A.R.T. data to assess if there are already errors.
The following table gives you a brief overview to which points we turn our centre of attention.
| Test | Observations |
| Sequential Read/Write Tests |

| Random Read/Write Tests |

Linux, XFS, why?
There are different reasons why we choose an operating system based on a Linux Kernel instead of a fresh Windows Vista/XP installation with all Service Packs.
- The filesystem XFS offers you flexibility you don't get from NTFS.
- The testprogram iozone runs natively under linux and offers a wide variety of possibilities.
- The test partly aims to server applications.
- Iozone gives you data on a statistical basis (error, deviation, etc.)
The filesystem is going to be built as follows:
mkfs.xfs -f /dev/sdbWe mounted with the following options:
mount -o rw,noatime,logbufs=8 /dev/sdb /mnt/ssdThe throughput is being measured using the following parameters:
iozone -Rb test_xk.out -i0 -i1 -i2 -+n -r xk -s4g -t2The operations per second are being measured using the following parameters:
iozone -Rb test_xk.out -i0 -i1 -i2 -+n -r xk -s4g -t2 -O
Why do we test different block sizes?
It is important to reproduce daily usage scenarios. Certain parameters need to be variable during the test to make a statement about the product. In our test the those parameters are the different block sizes. It defines the size in KBytes which is written/read on the drive during a transaction.
With this method one can test the reading and writing of either small or big files. In a normal personal computer environment you usually don't find files smaller than 16 KByte because the smallest amount of data which is written matches the block size. Even if your operating system wants to write/read an only 0.5 KByte small file a whole 16 KByte block is read. Furthermore the standard blocksize in Windows XP is 16 KByte.
In bigger RAID arrays the hard disk cache is usually disabled and the RAID-Controller takes over the job of caching. Exactly in such setups hard drives need to be very fast when reading or writing small amounts of data. Sequential throughput isn't interesting in this case.

Conclusion
With the Veloci Raptor 300 GByte Western Digital has a hard diks in its portfolio with very good performance figures. If we look at the sequential performance values we see that the drives only small problem because it isn't able to catch the leaed under these conditions. But on the other hand, when we look at the random read and write tests, we discover the strength of Western Digitals Veloci Raptor. Only under random write conditions with 4 KByte blocks the Veloci Raptor has to pass the lead to the much faster rotating Seagate Cheetah otherwsie the preformance figures mostly are way better than the competitors ones.
As MTBF (Meantime Between Failure) Western Digital declares 1'400'000 hours. Compared to earlier models the 2.5'' small Veloci Raptor got much more silent. During accesses the noise level is subjectively audible. Idle the Veloci Raptor is subjectively silent.
To a price of CHF 360.- you can buy Western Digital Veloci Raptor 300 GByte at PCP.ch.
