SANDISK HAS ANNOUNCED the latest addition to its solid-state disk (SSD) drive offerings aimed at data centres and large scale servers.
The Sandisk Ulltradimm is an enterprise class, ultra-low latency memory channel connected DDR3 drive aimed at write-once, read-many applications such as social media storage, though its write performance is good enough that it can still be rewritten safely, too.
The first Ulltradimm uses the standard DIMM slots to add storage to memory on a single board, resulting in write latency of 150µs, and read latency of less than five µs.
Because of its low latency, it is also ideally suited to crunching large amounts of big data, storage to support processing of time-critical financial transactions, and server virtualisation.
Read rates measure up to 150K IOPS with a sequential read speed of 1GBps. Write rates hit 65K IOPS with a sequential write speed of 760MBps.
Based on chips fabbed at 19nm, the Ulltradimm is available in 200GB to 400GB capacities scalable across memory slots.
With power failure protection for business continuity and a minimum time between failure (MTBF) measured at 2.5 million hours, the Ulltradimm drives have a five year warranty.
By utilising DIMM sockets, the Ulltradimm range significantly reduces the size of each rack, as it does not have to accomodate 2.5in or 3.5in form factors. This also means that the system can run at significantly lower temperatures, reducing the cost of cooling.
Sandisk has already made a number of announcements in the solid-state storage arena this year. In April the company launched the first 4TB SSD drive, with a promise that it was just the beginning of larger capacity SSDs. Shortly afterwards it launched the X300s range of self-encrypting drives for business laptops and desktops, which it claimed manage to encrypt and decrypt without affecting the drive's latency. µ
