The Samsung PM851 mSata 512GB is a 0" 512GB Solid-State Drive.
It uses the SATA 6Gb/s interface.
| Drive Type | Solid-State Drive | This defines whether the drive is a large-capacity slower hard disk drive, a smaller-capacity but much faster solid-state drive, or a hybrid | |
|---|---|---|---|
| Capacity | 512GB | The drive storage capacity is the limit to the size of files that can be stored | |
| Release Date | 01 Apr 2014 | The later the release, the more likely manufacturer support will still be around | |
| Read Speed | 540MB/s | The read speed is how fast the drive can read from data stored on it | |
| Write Speed | 380MB/s | The write speed is how fast the drive can store data | |
| IOPS | 100000 | The IOPS (Input/Output Operations Per Second) is a common benchmark used to measure drive performance | |
| Drive Interface | SATA 6Gb/s | The interface is the type of motherboard connection and defines the bandwidth limit of the drive |
The Samsung PM851 mSata 512GB is a solid-state drive, which means it stores data using flash memory similar to how USBs store data, but much more effectively. Solid-state drives perform much more effectively than hard disk drives, with faster read/write speeds, lower latencies, and even higher physical shock resistance, but come at a price premium. An SSD will cost much more than an HDD with an equivalent storage capacity - although SSDs are becoming cheaper and more viable over time. A common choice is to use a small SSD for an OS installation such as Windows for fast boot times and OS performance, and to use an HDD for applications and files. This avoids the negative point that over-use of data-writing can eventually lead to SSD degradation (although modern SSDs are said to take years before degradation), because Windows does not write much data, but its data is read often.
The Samsung PM851 mSata 512GB is a high-performance SSD and superior to any HDD.
Its read speed of 540MB/s is very fast, and should thus provide very quick loading speeds for applications and games. Its write speed of 380MB/s is quite fast, which should allow you to store data relatively quickly.
With a capacity of 512GB, the Samsung PM851 mSata 512GB has an impressive amount of storage space for an SSD and matches that of a small HDD. However big the drive, an SSD should always have enough unused memory to be able to rotate space and minimize the reuse of the same areas of the drive. Because each block of space has a limited lifespan, by spreading out the reuse of space it prolongs the lifespan of the SSD as a whole.
Using the SATA 3.0 6Gb/s interface this SSD will not be limited by its motherboard connection.
