nas disk vs sas disk?

[Dennis Lindström]

Hello! whats the diffrent between nas disk and sas disk?

 

iknow nas is network attuch storage and sas is serial attach storage.

but a network disk can also be use by multiplie users.

 

so here is my question im going to buy some ssd disk for Virtual machines.

why should i buy sas disk insted of nas disk?

nas disk for 1 tb cost around 100 euro and 1tb sas disk its way more expensive maybe 500-1000 euro.

how much do i earn by buying sas disk insted of nas disk.

sas is a storage interface

nas is just a type of network storage

SAS disk are going to be enterprise grade faster drives than NAS on SATA

Network Attached Storage refers to a complete storage system holding the data, and the method you use to access it. A complete NAS system is really just a type of server.

 

SAS refers to Serial Attached SCSI which is a type of hard drive interface, like SATA. You could build a NAS device out of an assembled motherboard, an operating system, and some SAS drives, just like you could out of a motherboard, operating system, and some SATA drives.

thx for the answers. but i google some more and i figureout that sata can only write or read in full speed at same time. but with sas its possible to do both at same time.

SAS drives are very expensive and are not supported on consumer platforms.
