Customers shopping for an all-flash array are typically looking for a high end product at a premium price. As such, the products highlighted on this list could be thought as the "sports cars" of the enterprise storage market.

When shopping for flash, be aware that the gear on this list varies significantly by capacity and toolset. So realize that the base price of a unit is not the only consideration when evaluating your purchase. Instead, balance your decision with the knowledge, for instance, of cost per capacity, and cost for the total toolset. In some cases – and depending on your needs – a higher cost may be more than justified for an all-flash array.

The results of the Enterprise Storage Forum survey, Data Storage Trends 2018, provides insight into flash in the enterprise.

Our methodology for including these items focused on the legacy reputation of the vendor, the depth and breadth of the product offering, and the product's ability to meet the demands of a high performance environment.

Here then are ten of the top vendors offering all-flash arrays (AFA).

Top Flash Vendors Comparison Table

Kaminario K2

Kaminario’s software-defined storage platform aims to build high performance storage infrastructure at cloud-scale. It can scale up or scale out based on application requirements. It is available as an appliance or software. Features include optimized RAID6, snapshot-based replication and workload agnostic. At 1.5M IOPs and a solid 5 9's of availability, this is a solid choice.

X-IO ISE 900

The ISE 900 series is available in two models. The ISE 920 G4 is available with 9.6TB to 242 TB effective and the 960 G4, which starts at the same 9.6TB effective but can scale to 725GB, supporting 60 SSDs. The X-IO ISE 900 is designed to support enterprise applications including virtual desktop implementation (VDI), server virtualization, online transaction processing, (OLTP), data warehousing, business intelligence and big data. Features include deduplication, RAID, and performance metrics with a customizable widget-based layout.

Fujitsu Eternus AF

The Fujitsu Storage Eternus AF delivers flash performance plus management integration with existing disk storage environments. Mirroring and transparent failover ensure nonstop operation, and automated quality of service minimize administration. Its two models include deduplication and compression options, automated quality of service management and transparent failover. This unit's 1 ms of latency is particularly impressive.

IBM FlashSystem 9100

A leader in flash due to its flash module design and Spectrum software defined storage, the IBM FlashSystem 9100 is clearly a major competitor in the market. Be aware of the guarantee of only 5 x 9s availability, and that due to the FlashSystem's advanced design some features are new. But certainly IBM has major design expertise in storage hardware. Potential users are encouraged to test it in their own environments. As the FlashSystem's feature set matures, it could take business away from companies like Pure Storage, Dell EMC, HPE, and NetApp, based on its advanced design.
