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 you system it feels much slower. The whole story gets even worse when you start a benchmark which does randomread/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
We test with activated caches and NCQ (Native Command Queueing) because they're also activated under daily use. But the data size tested is always at least twice the amount of the memory.
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 give you a brief overview to which points we turn our centre of attention.

There are different reasons why we take a operating system based on a Linux Kernel instead of a fresh Windows Vista/XP installation with all Service Packs.
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/sea
It is important to reproduce scenarios of daily usage. Certain parameters need to be variable during the test to make a statement about the product. In our test the 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 and big files. In a normal personal computer environment you usually don't find many files smaller than 16 KByte. The relative amount of small files is much bigger on a mail or database server. Therefore tests with small block sizes are of interest for database-based applications.
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.
The test first builds a file 4 GByte big (sequential, initial write) and afterwards there will be read from this file (sequential, read). One step later there will be the same on a random basis to see the influence of the access time (random reads/writes). You can compare 4 KByte block size with a text file with only few letters in it. MP3s and movie files conist of 256 KByte and even bigger blocks. If one for example copies 10'000 text files with a size of 25 MByte it takes much longer than copying a 25 MByte movie file. This is becauseauf of the access time which has a big influence with small files. Big files on the other hand aren't affected by the block size.

The throughout very well performance in sequential write and read is outstanding. With peaks of 109 MByte/s the Barracuda 7200.11 1 TByte reaches values which exceed even the claimed specifications of 105 MByte/s sustained read and write performance. As expected the performance breaks in when the hard drive does a lot of random read and random write operations. In this case you can clearly see the influence of 7'200 rpm against 15'000 rpm of a Cheetah high-end disk. But also in this test, compared to the other SATA competitors the Barracuda 7200.11 1 TByte does a good job but compared to the 1.5 TByte model there unfortunately is a performance gap.
This test shows the same characteristic like the one before. The difference is that we get the number of opertations per second.

The bigger the data blocks the lower the resulting value is a logical conclusion because the throughput is constant and gets much higher priority. Compared to the 1.5 TByte model this one can only keep up in the sequential write test. In all disciplines it can't cope with the performance of it's bigger sister.

With the Barracuda 7200.11 1.0 TB Seagate presents a hard disk with an above average capacity. The throughput is also astonishing: 109 MByte/s when the drive does sequential writing operations. When you consider that in the specifications only 105 MBytes are mentioned this value is even better. As usual with mechanical hard drives the performance decreases with smaller block sizes. So one can see pretty poor performance when the block size is 32 KByte or smaller and random reads and writes are performed. But compared to the other drives the Barracuda still reaches nices numbers.
When operating the Barracuda 7200.11 1.0 TB is very quiet. Even when the drive reads or writes data one nearly can't hear it. So the proclaimed acoustic pressure of 27 dB respectively 29 dB won't be crossed. The maximal power consumtion of 12 Watt and 8 Watts in idle are also respectable values.
The Seagate Barracuda 7200.11 1.5 TB is a solid product and we can recommend it as a data gatherer, as a fundament of a game PC or for a worstation.
The Seagate Barracuda 7200.11 can be bought at PCP for about CHF 196.-
