ICYDOCK’s latest product for NVMe U.2 SSD brings the next level of ultra high speed storage in a compact package with the ToughArmor MB699VP-B. The ToughArmor MB699VP-B is a ruggedized full metal SSD cage with hot-swappable drive caddies, supporting up to 4x NVMe U.2 SSD in a single 5.25” device bay.
Countless Options in a Single Bay
To fully use the speeds of NVMe SSDs, each drive bay uses its own miniSAS HD (SFF-8643) connector, maximizing NVMe U.2 SSD 's potential transfer bandwidth rate of 32Gb/s.
The MB699VP-B features hot-swappable EZ slide trays found throughout the ToughArmor series, allowing for easy swaps of U.2 drives and utilizing the hot-swapping function that U.2 SSD natively supports.
For extra protection, the EZ-slide trays are fully constructed with metal provided maximum protection to your valuable SSD inside and outside of the unit.
Not just the EZ-slide trays are made out of durable metals, the entire unit is also full metal construction, ensuring that the drives are safe and secure while inside the unit.
To bring more utility to your hard drives and SSDs, a LED is installed into the front of the mobile rack to provide drive status information at all time when the drive is powered on, off and accessed.
Active Power Technology (APT) allows each LED and the cooling fan to be active only when a hard drive is inserted into the enclosure. When the unit does power up, two 40mm cooling fan placed strategically behind the rear panel provide airflow throughout the entire cage cooling all 4 bays effectively and efficiently.
With two ball-bearing fans attached and three fan speed settings: high, low and off, depending on the drive usage, user can manually select the proper cooling option accordingly.
Never forget which drives belong in what bays. With our individual drive ID labels you’ll always know which drive tray belongs in your RAID array or which drive contains certain files. Freely unplug and rearrange them to better suit your configuration or simply remove them for a more simplified look.
The ToughArmor MB699VP-B supports 15pin SATA power cables with locking latches so you’ll never need to worry about cables unintentionally disconnecting from your enclosure. Once these cables are connected, they’ll lock into place and stay that way.

Optional M.2 to U.2 SSD Converter Adapter


If you have M.2 NVMe SSD, an optional ICY DOCK EZConvert MB705M2P-B M.2 NVMe SSD to U.2 NVMe SSD converter adapter can be used as an alternative inexpensive solution to transform your M.2 to U.2 form factor without the need to purchase another U.2 SSD.

"We used a hot-swappable IcyDock drive cage to house the U.2 drives. The MB699VP-B 4-bay 2.5" U.2 makes working with 15mm Z-height SSDs easy.

We didn't have many nice things to say when we first heard Intel would bring U.2 form factor SSDs to the consumer SSD market. The cabling is bulky and requires a second cable from the power supply to plug into the data cable. In a world filled with petite M.2 and body builder-like PCIe SSDs, U.2 SSDs feel old fashioned.......Read full article

"The ToughArmor MB699VP-B will only take one 5.25” device bay and handles the bulky cables and extra power cables that U.2 NVMe SSD’s require with ease. Many of our workstation cases and a handful of server cases have 5.25” device bays that often go unused; this makes the MB699VP-B very handy if you are planning on using U.2 NVMe SSD’s in your build......."

Frequent Asked Questions

The mounting screws for the device seem to be too short to secure the device onto my system, what should I do?


A: For computer cases that have a thick metal sheet, the included mounting screws (M3*2.5L) may not fully secure the device. Please use longer screws (M3*4L) to secure the device or contact us at for replacement screws.
Q: I'm using Intel/Broadcom Tri-Mode HBA and RAID cards with the MB699VP-B, but the drives do not show up in my system?

The issue is caused by RAID card manufacturers using a different pinout for Tri-Mode cards than is typically used for U.2 connections. When using the Tri-Mode cards with U.2 NVMe drives, a U.2 enabler cable must be used for Tri-Mode card to detect the U.2 drive, which reverts the pinout back to standard U.2 specifications. For more information, please Click here.

Q: I'm connecting my Oculink PCIe switch add-in card to the MB699VP-B via miniSAS HD (SFF-8643) interface, but the U.2 drives did not show up in my system.

The issue is caused by card manufacturers using a different pinout for Oculink card, which does not match the Oculink to miniSAS HD cable in use. It is recommended to consult the card manufacturer before purchasing the cable to avoid compatibility issue.


Please see the following Oculink Add-in cards we have found that may require special Oculink to miniSAS cable, please contact the card manufacture for more information
