Key points to note on these 0X2N98 Dell T340 Cables and limitations of different technologies where they are used:-

Dell PERC (PowerEdge RAID Controller) and other controllers can support a variety of hard drive types. There are four main types used in Dell 9th generation servers and up. There are specific configuration limitations and the specifics should be checked for the type of controller used. In addition, the types cannot be mixed in the same RAID set.

There is also transfer differences referred to as SATA 1, 2, or 3. They may also be seen as 3Gb/s, 6Gb/s and 12Gb/s. In order to get the maximum speed the hard drive, backplane, cables, and controller all have to support the set rate. In most cases, the higher specification is backwards compatible to the lowest common speed. Example - plugging a 6Gb/s hard drive into a 3Gb/s backplane will result in the speed being 3Gb/s.

• ::  Serial ATA (SATA): SATA drives are base hard drives in Dell PowerEdge servers. Serial ATA was designed to replace the older parallel ATA (PATA) standard (often called by the old name IDE), offering several advantages over the older interface: reduced cable size and cost (7 conductors instead of 40), native hot swapping, faster data transfer through higher signaling rates, and more efficient transfer through a I/O queuing protocol. On some systems without a controller, these can be cabled instead to the onboard SATA connections on the motherboard. On smaller servers with a controller, they can still be cabled because these systems will not have a backplane. Cabled hard drives are not hot swappable.
  
   
• ::  Near Line SAS: Near Line SAS are enterprise SATA drives with a SAS interface, head, media, and rotational speed of traditional enterprise-class SATA drives with the fully capable SAS interface typical for classic SAS drives. This provides better performance and reliability over SATA. Basically it is a hybrid between SATA and SAS.
  
   
• ::  Serial Attached SCSI (SAS): SAS is a communication protocol used in Enterprise hard drives and tape drives. SAS is a point-to-point serial protocol that replaces the older based parallel SCSI bus technology (SCSI). It uses the standard SCSI command set. These have extra connections through the top of the SATA connection. These are the top end in performance for electromechanical drives.
  
   
• ::  Solid-State Drive (SSD): An SSD is a data storage device that uses integrated circuit assemblies as memory to store data persistently. SSD technology uses electronic interfaces compatible with traditional block input/output (I/O) hard disk drives. SSDs do not employ any moving mechanical components, which distinguishes them from traditional magnetic disks such as hard disk drives, which are electromechanical devices containing spinning disks and movable read/write heads. Compared with electromechanical disks, SSDs are typically less susceptible to physical shock, are silent, and have lower access time and latency. Typically because of these features, SSD drives can be the fastest I/O in the market today in standard hard drive form factor.
