2.5” U.2 NVMe SSD HDD Adapter Hardwar Raid 0/1 2.5” allows add 2 slot SATA SSD B Key M.2, the transfer rate up to 10Gbps

Shentek 55014 2.5” U.2 HDD Adapter – 2 slot SATA SSD B key M.2 Card to Hardware Raid 0/1, The working speed is 10Gbps. It uses U.2 SFF-8639 to link with M/B. It is NVMe transfer and it also cost effect.


2 slot SATA SSD B Key M.2, it supports 2230, 2242, 2260, and 2280. The SSD supports with SATA spec, but to host transfer signal spec is U.2 SFF-8639. As we know NVMe spec is 32Gbps. Shentek 55014 it supports with 10Gbps, What is different? SATA SSD vs PCIe SSD. 55014 designs with 2 slot SSD, it has few reasons. –

Working temperature – SATA SSD has low working temperature

Cost effect – SATA SSD’s price is low then PCIe SSD

Hardware Raid – normally U.2 HDD Adapter does not supports Raid function, 55014 has design with Hardware raid function that is more safety.

2 slot SATA SSD B key M.2 – because of 2 slot SATA SSD, that is why 2.5” U.2 NVMe SSD HDD Adapter 55014 can support Hardware raid 0/1.


System requirements, Compatibility information Q&A

U.2 it supports with Windows 10 and up, for hardware you need a one port U.2 Host port(SFF-8643), one U.2 cable SFF-8643 to SFF-8639 the cable also needs to have one SATA 15pin for power in. With both, that we can add 2.5” U.2 NVMe SSD HDD adapter to your system.

It also supports with USB to 2.5” U.2 NVMe(PCIe) HDD Adapter,. With USB3.1 it supports 900ma 5V Bus power, it is enough for 55014 2.5” U.2 NVMe HDD Adapter. You do not need external power input for USB 3.1 Gen2 10G(USB3.2 Gen2 10G), just use USB Bus power is good enough.


Q: Does 55014 can add PCIe SSD to M.2 slot?

A: 55014 2.5” U.2 NVMe SSD HDD Adapter, it can not support PCIe SSD(NVMe SSD). Because the design is with SATA SSD, and it has few reasons. PCIe SSD is much high Then SATA SSD. Also working temperature is more low then PCIe SSD.


Q: Can U.2 cable work with SATA HDD

A: It could not work, because U.2 cable is PCIe signal not SATA signal. That is why U.2 NVMe cable could not work with SATA.


Q: What is different between 2.5” U.2 NVMe HDD Adapter(55014) vs 2.5” SATA HDD Adapter?

A: 2.5” U.2 NVMe HDD Adapter(55014), shentek designs with NVMe signal, that can support more transfer rate then SATA spec. But we use SATA SSD spec replace PCIe SSD.

A; SATA SSD’s price is much low then PCIe SSD

B; 2.5” U.2 NVMe HDD Adapter speed is 60% up then SATA 6Gbps speed, 55014 2.5” U.2 NVMe HDD Adapter supports 10Gbps transfer rate


Q: What is U.2 connector – SFF-8639?

A: It looks alike SATA 22pin connector, but SFF-8639 has total 58pin. One side is 29pin, it has two sides. It supports PCIe x 4 lanes with PCIe Gen3 spec. Total transfer rate up to 32Gbps. But we could not use SATA 22 pin cable to connect with SFF-8639. With 32Gbps transfer rate, it is full speed.


Q: 55014 – 2.5” U.2 NVMe HDD Adapter why does not support 22110 M.2 Card?

A: 2.5” U.2 NVMe HDD Adapter only supports with 2230, 2242, 2260, and 2280. It is with our 22110. The reason is 2.5” U.2 HDD Adapter does not have enough space for 22110 M.2 card. But supports with 2280 and 2260, that is for most of M.2 card’s spec.


Q: What Windows OS supports?

A: 2.5” U.2 NVMe HDD Adapter, it supports Windows 10 and up. It does not supports with Windows 7, XP. When you connector with Windows 7, it will show unknow device server on Device Manager. But we could not formate it. Because Windows does not support NVMe PCIe SSD spec.


Q: Who needs the 2.5” U.2 NVMe HDD Adapter?

A: shentek 55014 2.5” U.2 NVMe HDD Adapter is for all users to use. It is supports with SATA SSD M.2 Card. SATA SSD M.2 is much chip then PCIe SSD. Also SATA SSD is main SSD in marketing. Because is main SSD, that uses can easy to get it

With 55014 transfer rate up to 10Gbps. What which marketing – Gaming, DIY users, Enclosure users, and who needs date protection. With Gaming users, as we know it always want high speed and higher, it is 80% fast then SATA spec. DIY users, they just want to have better transfer speed, but care about the cost. Enclosure users. For NVMe enclosure, it supports with USB3.2 Gen2(USB3.1 Gen2) spec, as we know it is 10Gbps transfer, even we connector with full speed U.2 NVMe SSD, it is only can run with 10G, therefore, that is why 55014 2.5” U.2 NVMe HDD Adapter it supports with 10Gbps, that just good with USB3.2 Gen2(USB3.1 Gen2 10G) speed. With the 2.5” U.2 NVMe SSD HDD Adapter, you can get more better date transfer when you use with enclosure, also it save more cost for NVMe SSD.


Q: Does it support plug and play?

A: It does not support with Plug and Play. Because it is internal 2.5” U.2 NVMe HDD Adapter, it needs to open computer case, that is why it would not support with plug and play. But if user uses USB to NVMe Adapter or Enclosure, it will support with plug and play. The reason is it uses USB3.2 Gen2(USB3.1 Gen2 10G) function for plug and play, it does not support with U.2 HDD Adapter for plug and play.


Q: How to instill the 2.5” U.2 HDD Adapter and it needs driver?

A: 55014 2.5” U.2 NVMe SSD HDD Adapter, the case is standard 2.5” HDD 95mm size. it works all kind of Computer case’s 2.5” HDD space. Also it supports with 2.5” HDD Enclosure. It does not need driver for Windows 10 OS. It is just plug and play. We do not need to worry any Windows 10 OS does driver.


Q: Where we can buy?

A: So far we does not have partner yet. You can buy from our website or Amazon or eBay or PChome,….


Q: 2.5” U.2 NVMe HDD Adapter supports with Raspberry Pi or Arduino?

A: the 2.5” U.2 NVMe SSD HDD Adapter does not support Respberry Pi. Because it does not support with Driver.
