Portable SSD Raid Storage (M.2 NGFF, USB-C)

This SSD Raid Storage is a portable drive that allows you to install 2 x M.2 SATA SSD cards of various capacities. Install your own M.2 NGFF SSD cards if you purchase just the enclosure ($69) or have it installed (512GB or 1TB x 2) and tested for you!

Features:

• Metal enclosure with removable silicone sleeve that protects against drops and slipping.

• Supports 2 x M.2 NGFF¹ SATA SSD cards of varying sizes (22*30mm, 22*42mm, 22*60mm, 22*80mm) and capacities (up to 1TB).

• Type-C USB3.1 interface with data transfer speed of up to 10Gbps.

• Independent power LED indicators for each card.

• Supports Windows 7/8/10, Mac OS X, iOS operating systems.

• Supports JBOD, RAID 0 and RAID 1 modes².

• Highly portable dimensions (116.5*65*15.5mm).

Why should you have portable RAID1 storage for your laptop?

Scheduled backup offers a history of your data, but it does not protect you from disk failure and the loss of data that you have spent hours working. There are also situations where the backup is unavailable when your laptop is not connected to a secondary storage device.  

Notes:

1. NVMe SSD cards looks similar to NGFF SSD cards but use a different interface. NVMe cards cannot be used with this enclosure. 
   
2. Brief explanation of different modes (RAID 1 configured as default).

• JBOD allows the installation of SSD cards with different capacities and combine them to a single larger drive. Data cannot be recovered from the failed card.
• RAID 0 requires the installation of SSD cards with the same capacity and combine them to a single larger drive. Faster speeds than other modes but data cannot be recovered if either card fails.
• RAID 1 requires the installation of SSD cards with the same capacity. Total capacity of the drive is the same as the capacity of one card. Data can be recovered if either of the cards fails.

Performance:

• The SATA interface has a theoretical throughput of 600MB/s. Most recent SATA SSD cards will be able to reach 500MB/s+ for read speeds in non-RAID configuration.

What is RAID Level 1 ?

RAID Level 1 consists of data mirroring, without parity or striping. Data is written identically to two drives, thereby producing a “mirrored set” of drives. If either drive fails, the other continues to function as a single drive until the failed drive is replaced.

This RAID level is often used in servers for the system partition for enhanced reliability but PC enthusiasts can also get a nice performance boost from RAID Level 1.  If a request is broadcast to every drive in the set, it can be serviced by the drive that accesses the data first (depending on its seek time and rotational latency), improving performance.
