in random speeds which represent the devices ability to read/write many tiny files as opposed to one long string of data (sequential) and can be almost a 100 times higher than those of HDDs! Read (MB/s) 141 138 Seq. PS4 external hard drive than you need. The sheer amount of various capacities and models can be quite confusing because they are so similar to each other.
Upgrade ps4 pro hard drive 4tb
The 8TB model is slightly slower than the others but is fast nonetheless at 160/170 MB/s sequential read and write. In a magnetic hard disk drive, a read/write needle has to seek out the place on the drive s platters where data has to be either read from or can be written.
Parity data ensures redundancy, meaning that the parts of a striped file that are lost when a drive fails can be retrieved fully via these parity bits from the remaining drives.

Source: hard - drive -parts/ At first glance, choosing the best internal hard drive may seem quite easy just find one that costs the least per gigabyte from a reliable, well-known manufacturer and youre done, right? Cheap:.04-0.08 per. The seeking, decoding/encoding, and many other forms of latency add up, making, lets say, one megabyte of data to be transferred more slowly. 104-110MB/s sequential read and 91-103MB/s sequential write performance (between the 4 capacities) will do just fine in everyday use but dont expect lightning-fast loading times with these drives. The large cache allows more of frequently used data to be stored in the flash memory and, in turn, to be accessed more quickly than having to read it every time from the drive s platters. All capacities of Red Pro cost 30-60 more than the corresponding standard models (4-6.1 cents per GB, 6TB the cheapest) because of the higher speed class and the extended warranty.
