Who's who in SSD? - by
editor - October 2012
Renice Technology, founded in
and sells its own SSD
controllers, and also uses 3rd party SSD controllers in some of its SSD
The company markets SSDs in the
other things its SSDs compete in these form factors and interfaces:-
tiny SSDs, CFast,
PATA SSDs and
SATA SSDs, and
launched a native USB
3 SSD (no bridge chips) using its own controller IP which supports the
UAS (USB Attached SCSI)
protocol, has SMART and power interruption data integrity protection and R/W
speeds of 400MB/s and 320MB/s respectively.
From the customer perspective - if you've never gone down the customization
route for your SSDs - the first thought which might come into your mind is
this... Customization? That means doing more. Must mean more cost right? |

|Non-Balanced Wear Leveling
- a paper by Renice|
|Editor:- July 28, 2016 - Renice Technology
recently published a paper -
Wear Leveling Algorithm (pdf) - which outlines the thinking behind a
specific technique in its industrial SATA3 SSD controller - model
- to improve
upto 3x compared to traditional methods. |
This is one of the several techniques used in this
controller to overall get a 20x improvement in lifespan when using
the article (pdf)
Editor's comments:- Ever since the
first flash devices were evaluated it has been known that some blocks are much
better than others.
As an example in this paper Renice shows that
in a modern 16GB MLC flash chip - even after just 10 P/E cycles the controller
is able to see a 3x difference between the fastest and average program time and
over 30% difference between the slowest and fastest read times.
quality of wear resistance tells you something which can be used to grade
Renice's non-balanced wear leveling algorithm leverages
these naturally occurring process variations so that "the higher
wear resistance blocks are selected to be erased more times while the lower
ones get protected instead."
|Renice announces pSLC
|Editor:- March 22 , 2016 - Renice Technology
the imminent availability of a 2TB 2.5" SATA MLC SSD family for the
military market. The
R-SATA uses the company's
controller. Interesting aspects of this announcment are:-
- Renice says the drive can be used in pSLC mode - which halves the
capacity but "achieves nearer SLC performance and reliability".
Editor's comments:- Renice has a completely
different view about the efficacy of pSLC in this type of SSD - than
Cactus which dismissed
the notion that it was worthwhile in a recent
about memory geometries and ECC.
- the new SSD uses rugged SATA connectors which are work more reliably in
