Capacity and interface

The SanDisk Fusion ioMemory SX350-3200 is a 3.2TB internal solid-state drive that connects through a PCI-Express 2.0 x8 slot. It uses MLC flash memory and is built as a PCIe application accelerator for read-intensive workloads.

Workload fit

This drive suits web hosting, data mining, seismic data processing, content caching, 3D animation and CAD/CAM tasks where low latency matters more than raw bandwidth. It is not intended for general-purpose consumer storage or boot-drive duties.

Headroom and limits

Sequential reads reach 2.80 GBps and writes 2.20 GBps, with random performance up to 345K read and 385K write IOPS. Latency sits at 79 microseconds read and 15 microseconds write, so the drive handles heavy read queues comfortably but will saturate on sustained write-heavy streams.

Questions about this item

Does this card fit in a standard PCIe 3.0 or 4.0 slot?

The card uses a PCI-Express 2.0 x8 interface and will operate in any slot that provides at least eight lanes at Gen 2 speeds or higher.

What read and write latency should I expect for random workloads?

Random read latency is 79 µs and random write latency is 15 µs, with up to 345K read IOPS and 385K write IOPS.

Is any additional software or driver required to use the drive?

The drive relies on SanDisk VSL (virtual storage layer) software for direct memory access and low-latency operation; the appropriate driver package must be installed on the host OS.
