What best describes raid 5 storage?
Is raid 5 faster than raid 0?
For read access, a RAID5 is expected to have similar performance to a RAID0, in theory even a bit better if the access is seek-time bound. i.e. for a total cache miss, a single write in RAID0 translates into n-1 reads and 2 writes for a RAID5.

Why does raid 5 need 3 disks?
The RAID 5 array contains at least 3 drives and uses the concept of redundancy or parity to protect data without sacrificing performance. Similar to a RAID 0
RAID 0
In computer data storage, data striping is the technique of segmenting logically sequential data, such as a file, so that consecutive segments are stored on different physical storage devices.

array which stripes data across multiple drives to improve performance, RAID 5 stripes data but adds an additional stripe of data known as parity for protection.

What is the best raid 5 stripe size?
For RAID 5, RAID 50, RAID 6, or RAID 60, a stripe size between 256k and 512k would be ideal for tube sites and large file download sites hosted on hard drives, while a stripe size between 128KB and 256KB would be better when accesses are typically of small files, or when the data is stored on SSD.

Which is faster raid 5 or 50?
RAID 50 offers increased write performance and better data protection than RAID 5 in the event of a disk failure. RAID 50 is capable of faster rebuilds, a necessity at a time when downtime is considered unacceptable.
