Hitachi Deskstar 7K3000 review

£117 inc VAT

Manufacturer: Hitachi

Our Rating: We rate this 4 out of 5

The Hitachi Deskstar 7K3000 SATA 6Gbps drive tries to offer both performance and storage capacity for enthusiasts.

The Hitachi Deskstar 7K3000 internal hard disk drive is an entry into the rarefied space of drives that offer three-terabyte (3TB) storage capacity. Other brands in this space include Seagate and Western Digital.

Apart from the obvious storage space benefit and the high price, we look at how this HDD performs and help you find out if it is time you got yourself a 3TB drive.

Hitachi DeskStar 7K3000: Design and specifications

This drive uses five platters and ten heads to achieve the 3TB mark. Though it weighed a bit heavier, it looks like any other internal desktop drive from Hitachi, all the way down to the colour shade of the metal covering. It is a standard desktop HDD, with a 3.5in form factor and SATA 6Gbps interface. It spins at 7,200RPM and has a 64MB buffer.

Power usage claimed is 6.8W at idle. While in use under normal conditions, it was barely audible, just like any HDD. While testing and in heavy usage, the drive was less audible than the Seagate Barracuda XT 3TB. Heat was in plentiful supply considering it has a number of platters, but again it ran less hot than the Seagate 3TB drive.

Storage hardware reviews

The Hitachi Deskstar 7K3000 3TB (HDS723030ALA640) provides 2794.52 GB of usable space, after formatting. Hitachi only offers a three-year warranty on their product, whereas you'd get a five-year warranty on Seagate's 3TB drive. More details can be seen on this review's "Specifications" page or on Hitachi's product page for the drive.

As explained earlier, drives with capacity higher than 2.2TB need to be initialised in a different way (GPT mode), unless intermediary software or hardware solutions are used. With current motherboards supporting EFI boot, this is not an issue anymore.

Hitachi DeskStar 7K3000: Performance

Our colleagues at PC World India put the Hitachi DeskStar 7K3000 through its paces in their testing labs.

We run synthetic benchmarks and real world tests using the fastest PC components at hand, to remove most bottlenecks that hold back performance.

The test-bed consisted of an Intel Core i7 965 processor, Intel DX58SO motherboard, AMD Radeon 5970 graphics card, Intel X25-M 80GB SSD, WD VelociRaptor 300GB HDD, 12 GB of Silicon Power DDR3 RAM in triple channel, Tagan BZ-1300W PSU and Windows 7 Ultimate SP1 64bit edition. We used the latest WHQL signed drivers available at the time of testing. A RAMdisk drive was used for real-world file transfer tests, and a SATA-III adaptor to operate this drive at full capability.

Real world file read/write speeds stood at 118.8 MBps for a single large file (6.42 GB), but fell to 86.1 MBps as expected, when copying multiple smaller files (1287 files totalling up to 2.33 GB). Transferring files from the first partition to a second on the same drive was at a speed of 43.4 MBps. Read and write access times averaged 15.8ms and 6.06ms respectively. The drive racked up a HDD Score of 9460 in PC Mark 05.

On average, we measured a synthetic read speed of 147.3 MBps, and write speed of 132.9 MBps. The actual speed numbers and access times noted above, are both ahead of Seagate's 3TB HDD by a tiny margin, so this Hitachi drive is a good performer. The Buffered Read speed however, did not go any higher than 249.5 MB/s and did not utilise the bandwidth available on SATA 6Gb/s - so I'd say this is yet another HDD that takes the SATA 6Gbps name in vain.

  • Overall: We give this item 8 of 10 overall

The storage industry is willing to serve your ever-expanding data storage needs. Need to store lots of data in a single drive, and need that drive to be fast as well? This Hitachi drive is a viable choice and comes out ahead of Seagate's Barracuda XT 3TB. It is just a bit faster, less noisy and runs slightly cooler, thus reducing perceived uncertainty of drive lifespan. The lower price makes one feel less uncomfortable in recommending a new top-end product.
