Samsung's latest 2TB 'green' hard drive is targeted at the eco-conscious user who also values performance.
The Samsung Spinpoint F4EG 2TB (model HD204UI) enters the arena of 'green' hard disks. Besides the Samsung F4 EcoGreen, other 'green' disks in the market include Western Digital's Caviar Green series and Seagate's Barracuda Green series of hard drives. We test the hard disk and check whether it lives up to its eco-friendly credentials.
Samsung Spinpoint F4EG 2TB: Design and specifications
The Samsung F4EG 2TB is a standard desktop HDD with a 3.5in form factor. The hard drive features the standard SATA power and data connectors.
It comes with 32MB of buffer size and a standard SATA 3Gbps interface. The F4EG spins at 5400rpm and offers 1863GB of usable space after formatting. As per its specifications, this HDD's power usage 5.1W at idle, and an average of 6.3W during operation. Samsung offers a three-year warranty for this product. More details can be seen on this review's 'Specifications' tab or on Samsung's product page for the drive.
Under normal usage conditions, it was almost inaudible, like most normal hard drives. Even during heavy usage, the drive was relatively less audible compared to other drives. However, the vibration felt while in operation could have been lower, given that Samsung positions this disk in the 'green' disk segment, and that drives in such a segment are a good candidate for HTPC use.
The Samsung Spinpoint F4EG 2TB has three platters and six heads, with each platter having a density of 667GB. This is one platter less than its predecessor, the Samsung F3EG 2TB, as also most other 2TB disks in the market, whether positioned as 'green' or regular, that generally have 4 platters.
Samsung Spinpoint F4EG 2TB: Performance
We ran 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, 12GB of Silicon Power DDR3 RAM in triple channel, Tagan BZ-1300W PSU and Windows 7 Ultimate SP1 64bit edition. A RAMdisk drive was used for real-world file transfer tests.
While running synthetic tests, we measured a read speed average of 108.4MBps, and write speed average of 98.1MBps. Read and write access times averaged 15.75ms and 11.9ms (milliseconds) respectively. The drive notched up a HDD Score of 6855 in PC Mark 05.
Real world file write speeds stood at 147.7 MBps for a single large file (6.83 GB), but fell to 26.7 MBps when writing multiple smaller files (86,688 files totalling up to 3.25 GB). The speed seen while transferring the smaller files was expected as we used small files for a fairly intensive test. Real world read speeds were recorded at 103.2 MBps for large files, and at 61.3MBps for copying multiple smaller files.
Transferring a single big file (6.83 GB) from the first partition to a second on the same drive was done at 51.6MBps. Meanwhile, transferring multiple small files from the first partition to the second one was done at 15.54 MBps. A positive to take from this test, was that under heavy use, the hard disk barely felt warm to the touch.
These performance numbers are slightly lower than the 7200 RPM drives. This is as expected for a hard disk positioned in the 'green' segment, spinning at 5400rpm.
Screenshots shown below are some of the benchmarks. Note that performance recorded by different synthetic benchmark tools can sharply differ and is normal.

Read and Write Graphs from HD Tune Pro
The HD Tune Pro write graph above shows the dots spread across the vertical area, instead of being bunched together in the way the dots are on the HD Tune graph for read speed. This means access time varied drastically during testing, which is a bit unusual. It may not significantly affect user experience while using the HDD, but it's worth noting.
Read and Write, HD Tach RW Comparison Graph
The above HD Tach RW graph is a comparison between the Samsung F4EG and the Seagate Barracuda Green 2TB hard drives. As can be seen from the graph, the average read speed values of both the drives are similar. But comparing the write speed average of the drives, the F4EG (91.1 MBps) performs better than the Seagate Green drive (73.4 MBps).
The Samsung F4EG hard drive is a useful advance in storage density. Although, the fact that the F4EG can store 2TB across three platters, doesn't really translate to a significant advantage for this drive over other 2TB 'green' hard disks that achieve the same with four platters. However, replacing multiple smaller drives with a single high capacity drive is still advantageous in many ways.
