Deliver Time

  • Once your order has been handed over to the carrier for delivery, you will receive a shipment notification email with an estimated delivery date. Please note that it is not possible to expedite your delivery and receive your package earlier than the scheduled delivery date. Therefore, we are unable to accept requests for expedited delivery. Our carriers are unable to provide an exact time of day for your delivery. If you ordered multiple items, you may receive separate shipments.
  • All estimates are based on business days. We only make deliveries in the specified areas of Hong Kong from Monday to Sunday except on the first two days of the Lunar New Year and when typhoon warning signal No. 8 or above or black rainstorm warning is in force.
  • All rescheduling of delivery, additional purchases, new sales memos and amendments must be made 3 days before the scheduled delivery date. Otherwise, a double delivery charge will be incurred.
  • We may deliver the merchandise in one or more installments, and some of the merchandises may be delivered directly from suppliers. Any times and dates given for dispatch of merchandise, or the length of time that merchandise will take to be delivered, are only estimates. If we are unable to meet any stated dispatch or delivery dates or times we will inform you as to the progress of your order. You agree and accept that under no circumstances will we accept cancellation of order or refund.

Signature On Delivery

  • Most of our shipments contain valuable items. If you will not be in attendance to accept delivery of your purchase, consider shipping to someone you trust will be able to sign for your package. For your convenience, you may prefer to have your order delivered to your office address. If you choose this option, please include the name of your business in the address. Please note, if you choose this option, goods may be left with reception or the Mail Room.
  • As our carriers require a signature on delivery, the carrier will leave a calling card if you are not at home. Please contact the carrier to reschedule delivery.
  • For postal deliveries, no signature is required and order status tracking is not available.
  • Delivery failure due to no one answering the door upon the arrival of goods at the appointed time, or to circumstantial limitations such as the entrance being too small, will require a rescheduled delivery and therefore incur double delivery charges.
  • We will deliver the merchandise ordered by you to the address you give us for delivery at the time you make your order through our staff or a third party provider. You agree to present your photo identification upon request when you acknowledge receipt of the merchandise. The merchandise shall be, and shall be deemed to be, delivered and accepted by you when the merchandise are delivered to the address you give us for delivery. You agree and accept that we are entitled, at our option, to charge you additional costs or cancel your order in the event of your failure to accept delivery for whatever reasons.


  • You will become the owner of the merchandise you have ordered when they have been delivered to you. Once merchandise has been delivered to you they will be held at your own risk and we will not be liable for the loss or damage.
  • You may not export any products purchased at CHINAM online store. We sells and ships products to end-user customers only. Notwithstanding order confirmation, CHINAM may cancel any order where it has reasonable grounds to believe the product is not being purchased for end use.
  • If there is any inconsistency or ambiguity between the English version and the Chinese version, the English version shall prevail.
  • We reserve the final right to terminate or alter the above terms and conditions. In the event of any dispute, our decision shall be final and conclusive.

Add up to 16TB of SSD Storage! Install Two 2.5-inch SATA SSDs into a PCIe Card Slot

If you need faster, high-capacity internal storage for your desktop computer or server, 2.5-inch SATA SSDs are the cost-effective choice. Sonnet’s Fusion™ Dual 2.5-inch SSD RAID PCIe card enables you to upgrade your system in a flash, mounting one or two SSDs (sold separately) with up to 16TB capacity in a single full-length PCIe card slot, with no power or data cables, adapters, or mounting trays required.

Great 2-Drive Hardware RAID 0 Performance

Install the Sonnet Fusion card into a PCIe 3.0 slot of a computer or Thunderbolt 3 expansion system and achieve great transfer speeds up to 1000 MB/s!

Still use a Mac Pro® 5,1 tower? Enjoy performance up to 800 MB/s now, and migrate the Sonnet card to the new Mac Pro (2019) to enjoy even better performance.

Disk Striping

Increases performance by interleaving data into blocks (stripes) across two or more drives simultaneously to increase speed.

Fast RAID 1 Performance

Looking for the safety of a simultaneous backup? RAID 1 performance of up to 560 MB/s may be obtained with any compatible computer or expansion system.

100% Redundancy

If primary drive crashes, the mirrored drive will automatically replace the primary drive.

Hardware RAID Controller Onboard

A high performance RAID controller manages the SSDs you install, supporting Fast (RAID 0), Safe (RAID 1), Volume (Span) and, particularly important to pro audio users, JBOD (Just a Bunch of Disks) configurations, so you can choose the mode that best suits your needs:

  • Fast - Choose RAID 0 for the best performance.
  • Safe - Choose RAID 1 for a mirrored backup of your data.
  • Volume - Choose Span to create a single large volume bridging both drives.
  • JBOD - Choose JBOD (Just a Bunch of Disks) to work with twice as many audio tracks.

Regardless the mode you select, changing the configuration is easy – with no software to install or jumper blocks to move around, a turn of a switch and the press of a button is all it takes.

Fast USB Speed and Plenty of Power for Bus-powered Devices

Sonnet’s Fusion Dual 2.5-inch SSD RAID card also includes a SuperSpeed USB-C (USB 3.2 Gen 2) port that supports data transfers of up to 1000 MB/s, and provides up to 15W of power to support bus-powered devices—you can connect a fast external drive without installing another card.

Thunderbolt Port? Connect Two SSDs Through One Cable

Got a Thunderbolt connection, but no PCIe card slot? Fusion Dual 2.5-inch SSD RAID card provides full performance and is ideal for use in a Sonnet Thunderbolt expansion systems. The combo enables you to add two SSDs plus a USB-C port to any Mac (M1, M2, M1 Pro, M1 Max, M1 Ultra, Intel), Windows, and Linux computer with Thunderbolt ports.
