Flash Memory on PCI Express

The concept sounds rather simple: Fusion-io takes a PCI Express add-on card and puts Flash memory and a powerful controller on it. The result is the ioDrive, which in fact should not necessarily be called a drive, as it has little to do with hard drives as we know them. Fusion-io calls its product a NAND flash cluster, and it was designed to provide DRAM-like performance. In fact the ioDrive cannot be used as a drive: it connects via PCI Express and hence it is not possible to boot an operating system from it--at least not yet--Fusion-io says it is working on that...


Application scenarios for this product are few in the desktop space; the product was designed for high performance servers. That said, it is definitely possible to install it into any desktop PC that has a x4 or wider PCI Express slot, if you think you have an application for it. When we first received the sample we were still limited to Linux, but Windows 64-bit drivers have been around for several weeks now. There are no 32-bit drivers available at this point.

Intel’s X25-E SSD Walks All Over The Competition

Intel's new X25-E professional flash SSD is a rocket when it comes to fast I/O performance. Is Intel now the source of the best server drive? We compare the X25-E against its mainstream predecessor, competing SSDs, and 15,000 RPM HDDs.

They Did It Again: X25-E For Servers Takes Off

The first solid state drive by Intel was the mainstream X-25 M, which we reviewed last September. It is available in capacities of 80 GB and 160 GB, and its performance and power efficiency set new standards for desktop systems and notebooks. However, since it is based on MLC flash memory, its write throughput and I/O performance generally aren't considered suitable for servers and workstations. That all changes with the introduction of the X25-E SLC-based SSD.


X25-M/X25-E: Why Two SSDs?

There are two different types of flash memory on the market: multi-level cell (MLC) and single-level cell (SLC). MLC stores multiple bits of data in each flash memory cell, making it less expensive. SLC costs much more, but allows direct access to each bit of data, which enables better performance for random access and write operations.
Let me give you an example: the X25-M, which has been Intel’s desktop flash SSD product, reaches a level of 200 MB/s in read throughput, but it only writes at up to 75 MB/s. And although it provides great I/O performance, an SLC-based flash SSD can do much better.
