the Fastest in-production shipping SSDs - © STORAGEsearch.com

rackmount SSDs Earlier versions of this document only listed the single fastest rackmount SSD in each u-size (1U, 2U etc) - but there were some disadvantages in that method. So instead this now includes a mini list of the most important companies and product lines in this market space which covers a range of different interfaces and architectures. You'll have to look at each vendor's own offerings to get the exact specifications - but these are the vendors who are positioning themselves as the companies to beat in terms of latency and throughput. ultrafast rackmount SSDs (RAM SSDs):- Kove's XPD fast rackmount SSDs (fastest flash systems):-



IBM's FlashSystem

Mangstor's NX-Series

EMC's DSSD

SanDisk's ION Accelerator

Violin's 6600

Speed has a different value in fault tolerant rackmount SSDs - where the raw latency and IOPS may be outweighed by user preferences about the exact design and consequences of the differing FT architectures.

Memory technology, generation level (2, 3 or upcoming 4), the number of lanes and the API integration with critical apps are some of the vital filters in assembling any list of really fast PCIe SSDs. And that's before you get you controller architecture.



In the RAM SSD category - the fastest PCIe SSD is PMC's Flashtec NVRAM drive family . This RAM SSD in PCIe form factor has a x8 lane, PCIe 3.0 host interface - 16GB capacity - rated at over 10 million IOPS.



In the flash based PCIe SSD category - the fastest flash based PCIe SSD (at the time of writing - September 2015) is Mangstor's MX-Series . This is the fastest according to either IOPS or latency when compared to any of the previous industry leaders in this category listed in these pages.

3.5" Although the 3.5" form factor was at the sharp end of SSD performance in earlier phases of SSD history - it is no longer a launchpad for new high speed products. Although you will find some older legacy 3.5" SSDs which were fast at the time they were launched - they are mostly EOL - or simply available for old designs. Instead you'll get better results by installing one or more smaller SSDs in a 3.5" carrier module.

1.8" The question arises - what kind of interfaces are available for 1.8" SSDs?



At the time of writing this I'm unaware of any 1.8" PCIe SSDs.



That leaves the speed race to SAS SSDs. .

M.2 SSDs This form factor is becoming a surprising hotbed of innovation and (surprisingly) even speed.
