Solidata Crator Series – the most reliable SSD yet?

Solid State Disks have taken a bit of a beating lately with the demise of OCZ (purchased by Toshiba).  Talk focussed on reliability and the high failure rate of the consumer side of the OCZ brand let them down.  It seems that the strive for speed at a low cost is not acceptable when they then fail and you lose it all.

Look back to the early days of the USB pen drive, a technology that eventually lead to the birth of the Solid State Disk (SSD), and just pulling the USB drive out without cleanly closing the device within Windows, could cause the device to lose all that was on it.  How can this be?  It’s plug and play right? Well the answer is in the write phase.  As a Flash drive writes, it first needs to erase, this action and the writing of the data takes longer than the user notices as it is queued up within the drive.  Pull the USB out before this has finished and you could corrupt the whole index which the drive uses to reference where all of the data is located.  Faults can occur where on the next insertion of the USB pen drive shows an empty, unformatted drive where all data is lost.

The same can happen with Solid State Disks where they disappear from the system that they are installed in.  A lost index can mean a lost SSD.  Sudden loss of power can cause such a problem.  Crashed operating systems and blue screen of death that require a hard boot while the SSD is writing can be catastrophic. 

Solidata’s Novachips Power-loss Protection Mechanism

Solidata are a small but very professional Solid State Disk manufacturer based in the tech city of Shenzhen in mainland China, just next to Hong Kong.  The focus of their products is to focus on the niche market, finding solutions through product development to meet the needs of the industrial and military market.  They were the 1st to introduce a 2TB SSD in 2.5 inch format and one of the first to bring 1TB to market using MLC rather than TLC technology.

Introducing the Solidata Crator Series – there are 2 ranges available using MLC and SLC NAND Flash.  Using a SATA III interface, these drives have great performance at 470/470Mb/s Read and Write speeds with Max Random IOPS of 55000/60000 these drives offer consumer SSD type speeds but with the additional benefit of using a super capacitor which can provide up to 20 seconds of 3.8v power to the drive following abrupt power loss.

20 seconds of power!

That is many many times more than what is required, here’s the clever bit.  In very cold conditions (even as low as –40 deg C) when a capacitor decreases in performance of typically 10% for every drop of 10 deg C in temperature.  Therefore at even –40 deg C the capacitor will still work at 40% of its capability equating to 12 seconds of sustained voltage.  The drive will never need more than a couple of seconds to safely write the buffer and flush the data from the write bus.

This means that these drives will not only provide 100% power los protection, but they are able to do that even if used in extreme conditions.

The capacitor only gets used when power is lost from the drive and can be charged and discharged 500,000 times.

This Industrial Grade super capacitor is a physical part of the system board within the SSD and so is not built in by firmware or software.  It is ideally designed for military and high end industrial applications requiring 100% power loss protection and great read/write speeds.

Is this the most reliable SSD out there?  We think so.
