Value for money-SATA
SATA is considered to be the earliest enterprise solid state drive, and the price is lower than similar products. This hard drive is divided into 2.5-inch and 3.5-inch box-shaped designs, with a bandwidth of 6GT/s.
Faster and more reliable-SAS
SAS solid-state drives have higher data transfer rates, support dual-port operation, and are more reliable in terms of error correction, data integrity, and high signal quality. This type of hard disk is mainly used for enterprise servers and storage arrays that require high availability and I/O capabilities.
Miniaturized design-U.2
U.2, also known as SFF8639, is the most commonly used interface design. This design is box-shaped and supports 4-channel PCIe interface, as well as SATA and SAS interfaces. Its power consumption is 20W, it can be plugged and unplugged, and it also supports redundant storage, such as JBOD/JBOF. Up to 24 U.2 SSDs can be supported in a 2U server.
Powerful interface-AIC (expansion card)
The expansion card is card-shaped and connects to the PCIe card slot inside the server. It only supports solid-state drives with PCIe interfaces. This kind of hard disk is different from U.2 and cannot be plugged or unplugged under power, but it supports more than 4 PCIe channels.
Compact form factor-M.2
The card-shaped solid state drive M.2 is mostly used in data centers. The interface of this hard disk is more compact than other hard disks. It uses PCIe or SATA communication. Amphenol ICC's U.2 can achieve 4th and 5th generation PCIe performance if used as an enterprise solid state drive. Similarly, Gen 3/4 PCIe and M.2 have 16GT/s performance, and 24G SAS can achieve higher bandwidth.
Next Generation Solid State Drive (SSD)
The shape design of solid-state drives has been improving to keep up with the increasing application demand. Amphenol ICC has always been one step ahead when developing next-generation products, and its advantages have been reflected in the early to current products. Early solid-state drives used SAS 2.0/3.0 and other standards, and future interfaces will be based on advanced standards such as SAS 4.0. Similarly, the development from PCIe 3.0 to 4.0 will meet the requirements of the 4th and 5th generation solid state drives.
PCIe 4.0 and 5.0
EDSFF and NGSFF, the two form factors of solid state drives, can meet the requirements for running the 4th and 5th generation PCIe/NVMe storage protocols in storage servers and flash memory arrays. The relevant design can be plugged and unplugged when power is on, and it is equipped with a dual-port interface that supports redundancy. It is an effective replacement for M.2 in front-end service storage applications. The interface design of EDSFF supports 12.5mm slot pitch storage arrays, and NGSFF solid state drives can form 11mm slot pitch arrays in a smaller space. Both can be adjusted according to heat dissipation requirements. EDSFF is designed to support three standard solid state drive shapes: 1U long, 1U short, and 3" to meet different usage patterns.
24G SAS
24G SAS has a high data transfer rate and is the first choice for mission-critical storage applications in the future. The transmission speed of SAS 4.0 is 24GT/s, which is comparable to the latest NVMe/PCIe solid-state drive interface, and the speed performance is also comparable to that of NVMe solid-state drives.
Amphenol ICC has a wide range of next-generation connectors that can support the next-generation solid state drives with the above-mentioned interface design. Our SAS 4.0 connector supports 24G SAS interface solid state drives, and the Cool Edge connector meets the PCIe standard.
