What is U.2?

Formerly known as SFF-8639, is an interface standard defined by SSD Form Factor Work Group.

It was developed for the enterprise market and designed to be used with new PCI Express drives along with SAS and SATA drives. It uses up to four PCI Express lanes and two SATA lanes.

U.2 connector supports NVMe standard protocol and PCI-E 3.0×4 bus, which makes the U.2 SSD have a theoretical bandwidth up to 32Gbps and have advantages of high speed, low latency, and low power consumption.

Currently, HGST Ultrastar SN100, OCZ Z-Drive 6000 and other enterprise-class SSDs have a common feature, that is, they provide two form specifications. One is the traditional PCI-E expansion card model, and the other is the 2.5 inch U.2 interface disk style.

In November 2015, Intel introduced the 750 series SSD which is available in both PCI Express and U.2 variants.

However, the U.2 SSD that can be bought by ordinary consumers includes the Intel 750 series, which includes three capacity specifications: 400 GB, 800 GB, and 1.2 TB.

The sequential reading and writing speed of the Intel 750 U.2 SSD of 1.2TB capacity can be up to 2400 MB/s and 1200 MB/s, respectively. As for its random reading and writing speed, this SSD can reach 440000 IOPS and 290,000 IOPS, respectively. In a word, the performance is very strong. If you want to know the explanation to terminologies about disk performance, please read the recommended article.

In addition, ASUS, Gigabyte, MSI, ASRock, and other vendors have announced support for U.2, and demonstrated the new U.2 data line and U.2-M.2 converter. At present, the ASUS ROG Maximus VIII Extreme motherboard has been equipped with a U.2 interface.

The U.2 connector is mechanically identical to the SATA Express device plug, but provides four PCI Express lanes through a different usage of available pins.[3][4]

U.2 devices may be connected to an M.2 port using an adapter.

U.2 compared with M.2

  • U.2 allows hot-swap, whereas M.2 does not.
  • U.2 can use 3.3 V or 12 V for power, while M.2 only supports 3.3 V.

How to initialize a new disk using Disk Management

If you add a brand new disk to your PC and it doesn’t show up in File Explorer, you might need to add a drive letter, or initialize it before using it. You can only initialize a drive that’s not yet formatted. Initializing a disk erases everything on it and prepares it for use by Windows, after which you can format it and then store files on it.



If your disk already has files on it that you care about, don’t initialize it – you’ll lose all the files.

To initialize new disks

1. Open Disk Management with administrator permissions.

To do so, in the search box on the taskbar, type Disk Management, select and hold (or right-click) Disk Management, then select Run as administrator > Yes. If you can’t open it as an administrator, type Computer Management instead, and then go to Storage > Disk Management.

2. In Disk Management, right-click the disk you want to initialize, and then click Initialize Disk (shown here). If the disk is listed as Offline, first right-click it and select Online.

Note that some USB drives don’t have the option to be initialized, they just get formatted and a drive letter.

3. In the Initialize Disk dialog box (shown here), check to make sure that the correct disk is selected and then click OK to accept the default partition style.

The disk status briefly changes to Initializing and then to the Online status.

4. Select and hold (or right-click) the unallocated space on the drive and then select New Simple Volume.

5. Select Next, specify the size of the volume (you’ll likely want to stick with the default, which uses the whole drive), and then select Next.

6. Specify the drive letter you want to assign to the volume and then select Next.

7. Specify the file system you want to use (usually NTFS), select Next, and then Finish.

About partition styles - GPT and MBR

Disks can be divided up into multiple chunks called partitions. Each partition – even if you have only one – has to have a partition style – GPT or MBR. Windows uses the partition style to understand how to access the data on the disk.

As fascinating as this probably isn’t, the bottom line is that these days, you don’t usually have to worry about partition style – Windows automatically uses the appropriate disk type.

Most PCs use the GUID Partition Table (GPT) disk type for hard drives and SSDs. GPT is more robust and allows for volumes bigger than 2 TB. The older Master Boot Record (MBR) disk type is used by 32-bit PCs, older PCs, and removable drives such as memory cards.

To convert a disk from MBR to GPT or vice versa, you first have to delete all volumes from the disk, erasing everything on the disk.
