5400.4 The drive is the second generation Perpendicular Recording 5400RPM drive Seagate, offers some improvements on the old model. On paper, these articles draw less electricity, to accelerate the speed of internal messages, higher density allows for platinum greater capacity, and the best of all Seagate reliability. While all the specifications to look at the paper in large part, how this player works plays in our real world tested?

Design
5400.4 The new hard drive Seagate has some differences compared to 5400.3 elderly, including a recent motherboard layout, label difference cases, and a small port chimney. Most of these changes are relatively low and most people wouldn 't able to detect changes. In total, which gives 'is inside the importance of the role, and the reader can read pink for all I care, because it won ' t be seen once installed inside the laptop.
The performance
5400.4 speed reader is quite impressive, far beyond my original expectations. Going on paper specifications, the persistence of internal transfer speeds were 58MB / s in the new 5400.4 readers across the board, regardless of its capacity, where, as 5400, 3 were 44MB / s And in 7200.2 59MB / s for the ability I had in hand. This speed is well 5400RPM player in the field of 7200RPM drive at an affordable price. For purposes of the test, we HDTune and ATTO Disk Benchmark compare all three discs, all with my Lenovo ThinkPad T60-Notebook.
As you can see not only the new drive 5400.4 blow away 5400.3 oldest, but also my reader 7200.2 damage in all categories, but the speed of access. Although my player pushes a year today, I originally paid $ 120 for 120 GB drive, where now a 250GB hard drive is faster and cheaper to only $ 109.
Another amendment, but not so obvious is the difference between the power of newer and older generation 5400RPM-ROM. Slow and ensure draw remained the same at 0.6/0.2W between each model, where reading / writing was something different. Former 5400.3 has less electricity to read with 1.9W, with the new 5400.4 as 2.0W. Of the new posts on the reader is better measured in 1.6W, and the elderly consume 1.8W. Given that these changes are so small, you probably won 't even notice a difference but it could add an extra battery for 3-4 minutes of racing.
The new products offer, that the reader
With this player beat the market only a few months, most manufacturers are still pushing its record of former Seagate and other manufacturers ' pushes it chose to make. We have yet to see, all laptops in our online shop with one of these readers, but we have seen in a new external USB storage drive. I hope that consumers won 't have to wait too long for this player, but given that breath he really far the oldest model transfer rates, and the best of all offers much more capacity.
