Write and read speeds of 5200 rpm hard drive

Twitter Facebook Google Plus Linked in Higher revolutions per minute represent a faster hard drive, but the rate of media transfer is just as important for data storage solutions.

Back then, HDD technology included washing machine-sized monstrosities with platters up to 14 inches in diameter spinning at a mere revolutions per minute RPM.

Since then, the industry has experienced dramatic innovation. The physical footprint of hard drives has continued to decrease while storage density and performance have dramatically increased. But even as hard drive technology has matured, the way of measuring the performance of new hard drive models has remained relatively consistent and closely related to two specifications: This is commonly referred to as data throughput and typically measured in gigabytes or gigabits per second.

In either case, data throughput is directly related to how densely data is packed on the hard drive platters and how fast these platters spin. Comparing measurement methods For the areal density specification, we can measure data density on a hard drive in two ways: As tracks are placed closer together, TPI increases.

Similarly, as data bits are placed closer and closer to each other along a track, BPI increases. Together, these represent areal density.

As a rule, when areal density increases on a hard drive, so does data throughput performance. For the RPM specification, platters need to spin faster to increase performance in a hard drive.

Consequently, this specification is important when evaluating the expected performance of a hard drive or when comparing different HDD models. So RPM should still matter, right?

Therefore, when data is requested by host computers there is typically not a dependence on pulling this data directly from the spinning media in the hard drive portion.

Sometimes, however, data will be requested that is not in the NAND flash, and only during these instances does the hard drive portion of the device become a bottleneck.

Since the technology is so effective at identifying and storing frequently used data in the NAND area, SSHD technology is much more efficient in delivering data to a host computer quickly.

Instead, let solid state hybrid drives take your digital lifestyle to a higher level.Laptops are convenient because of their portability and small form factor as compared to a desktop computer.

Unfortunately, laptops are not as easy to upgrade. One of the few ways to upgrade a laptop that can have a huge impact on performance is to install a laptop hard drive. Fortunately for Newegg. Install some hdd benchmarking software and see how much your current hdd gives you in MB/s.

Compare that to the / MB/s read/write speed of the samsung pro for example. To give you a real world idea, switching from a gb rpm hdd to a samsung gb ssd reduced my windows load times from seconds to 10 . But a RPM hard drive like the WD WDBPKX Black is (slightly) faster than a RPM drive.

According to some benchmarks that I saw, the WD Scorpio Black is capable of achieving up to MB/s read speed, and around MB/s write speed. That is definitely faster than the RPM hard drive that my laptop has. Jul 06,  · The drive is about a year and a half old and causes no problems what so ever, excluding the speeds.

The problem I am having is that read and write speeds are extremely slow. For SSDs, 4k read/write speeds of about MB/s is typical. With a QD32, this can reach MB/s. The drive is reading/writing multiple files in parallel from the perspective of the computer.

RPM vs RPM: When Slower Is Actually Faster Friday, September 30th, platter-based hard drive. five year old RPM drive with a lower areal density and linear recording technology topped out at roughly 50MB/s read write speeds.
