Product Overview of the M.2 SATA 2-bay Raid

The Lenovo 4Y37A09739 Thinksystem M.2 SATA 2-bay Raid Enablement Kit is an accessory kit that can be used to upgrade the storage capacity of Lenovo ThinkSystem servers. This kit is designed for M.2 SATA solid-state drives (SSDs) and includes everything needed to add a RAID 0 or 1 configuration to a server.


RAID stands for Redundant Array of Independent Disks. RAID is a technology that combines multiple physical disks into a single logical unit for the purposes of data redundancy, performance improvement, or both. There are several different RAID configurations, each with its own strengths and weaknesses.

RAID 0 and RAID 1

The Lenovo 4Y37A09739 kit supports both RAID 0 and RAID 1 configurations. RAID 0 is a configuration that stripes data across two or more disks, allowing for improved performance. However, RAID 0 does not provide any redundancy, meaning that if one disk fails, all data is lost.

RAID 1, on the other hand, mirrors data across two disks. This provides redundancy, meaning that if one disk fails, the other can still be used to access all data. However, RAID 1 does not provide any performance benefits.


The Lenovo 4Y37A09739 kit is designed specifically for M.2 SATA SSDs. M.2 is a form factor for SSDs that is smaller and more flexible than traditional 2.5-inch and 3.5-inch form factors. M.2 SSDs can be used in a variety of devices, including laptops, desktops, and servers.

SATA is a standard for connecting storage devices to a computer or server. SATA is widely used and provides good performance for most applications.

The Lenovo 4Y37A09739 kit includes two M.2 SATA SSD trays, allowing for the installation of two M.2 SATA SSDs in a Lenovo ThinkSystem server.


The Lenovo 4Y37A09739 kit is compatible with a wide range of Lenovo ThinkSystem servers, including the SR530, SR550, SR570, SR590, SR630, SR650, SR850, SR860, SR950, ST550, and SN550. Compatibility may vary depending on the specific model and configuration of the server.


Installation of the Lenovo 4Y37A09739 kit is straightforward and can be done by following the included instructions. The kit includes all necessary cables, brackets, and hardware for installation.

First, the M.2 SATA SSDs must be installed in the provided trays. These trays can then be inserted into the server using the included brackets. Once the hardware is installed, the RAID configuration can be set up using the server's BIOS or software tools.

Benefits of RAID

Adding a RAID configuration to a server can provide several benefits. RAID 0 can improve performance by striping data across multiple disks, allowing for faster read and write speeds. RAID 1 provides redundancy, ensuring that data is not lost in the event of a disk failure.

In addition to RAID 0 and 1, there are several other RAID configurations that can be used to provide additional benefits. RAID 5, for example, provides both performance and redundancy, while RAID 6 provides additional redundancy and fault tolerance.

In Summary, the Lenovo 4Y37A09739 Thinksystem M.2 SATA 2-bay Raid Enablement Kit is an accessory kit that allows for the installation of two M.2 SATA SSDs in a Lenovo ThinkSystem server. This kit includes everything needed to add a RAID 0 or 1 configuration to a server, providing improved performance or redundancy,

PC expansion cards

Are you looking to increase your system's functionality? The expansion module is your best bet to achieving this goal. Here on allhdd.com, we offer you some of the best PC expansion cards/expansion modules at the best prices. Kindly go through these categories, including Storage Controller, PCI-E, 10GB, and Controller Cards, to select the expansion cards that meet your needs.

What is An Expansion Module?

An expansion module, which is otherwise called an expansion card, or accessory card, is an integrated circuit board inserted into the expansion slot on a computer system's motherboard. It is also inserted into the backplane or riser cards to add extra features to a computer system through the expansion bus.

Why Do You Need an Expansion Module?

Your PC is highly modular by design, and expansion modules significantly increase the system's functionality or capabilities. PC expansion cards will broaden the capability of a system by adding extra resources.

Suppose some functionalities didn't come with your computer system out of the box, an expansion module can increase functionality by adding abilities that were not in the original system. The intuitive users will appreciate an even better functionality despite their PCs having it already.

For example, you may want to improve your video graphics by installing a video card even if your processor or motherboard came with integrated graphics.

While these cards are sometimes expensive, you stand to enjoy affordable prices on expansion cards from the best brands on the market.

Types of Expansion Module

Sound Cards

If you are an ardent gamer or watch a lot of TV or videos on your PC, then you'll need a sound card. In addition to better sounds, you'd need a dedicated sound card to shed CPU usage, although some dedicated graphics cards can help manage some of the processor's audio load. The sound card redirects the workload from your GPC or CPU, and as a result, you enjoy enhanced frame-rates while gaming.

Video Cards

Video cards or graphics cards tend to be a very wise investment over time. The Graphics Card has the job of delivering an image to your monitor. While modern PCs boast some high-res display, you can even make it better with a high-quality video card. Given that your PC has a free compatible expansion interface, you can install an independent video card if your PC didn't come with any.

Storage Cards

There are many storage solutions available on allhdd.com through the use of expansion cards. Suppose you wanted to integrate a SCSI tape array into your system. In that case, you can add an expansion card to connect to SCSI "Scuzzy" devices. In stock, we have expansion modules that are fully-fledged solid-state drives. Other notable expansion modules include the TV tuner cards that enable a PC to make a cable television connection, wireless/cellular cards, riser cards, video capture cards, and modem cards.

Enjoy affordability, warranty, free ground shipping across 48 U.S. states, and a commendable customer help center when you shop quality expansion modules on allhdd.com.
