KingSpec E3000S Challenger SSD Review – EMLC Endurance and LSI SandForce Performance

Kingspec Challenger E3000 SSD Featured3Our SSD analysis this week displays only the second consumer available SSD to hit the streets with eMLC 10,000 P/E rated memory.

The KingSpec Challenger E3000s SSD is enterprise grade, LSI SandForce Driven, and relies on Intel eMLC memory.  Unlike other SSDs tested to date, the E3000s was able to provide great low 4K random write performance of 112MB/s, surpassing that 100MB/s 4k random write plateau that has eluded so many others.

THE KINGSPEC STORY

KingSpec is an ‘SSD and SSD only company’ that has been in business since 1995 and is located in Shenzhen, China. KingSpec has 1200 employees and is situated within a 15000 square foot facility and, if you might believe it, is capable of producing 3 million SSDs per month.

As much as we might tend to believe that this type of operation would be more concerned with volume than quality, we were set straight when we took a good look at this web page dedicated to their certifications which include REACH, ISO, CE FCC and RoHS.  Not only does it speak to each certification, but also, each is fully available for examination by the reader and includes specifics of the accreditation, many that describe SSD build quality measures specifically.  We found this accreditation, particularly interesting.

E3000S SPECIFICATIONS

The KingSpec E3000s is available in capacities of 60, 120, 240 and 480GB and all contain a standard KingSpec two year warranty. KingSpec lists different performance specifications for each capacity which is a bit unusual for LSI SandForce Driven SSDs, however, the performance listed for our 240GB capacity is 500MB/s read and 480MB/s write with a high of 50,000 IOPS.  We are confident in stating that all capacities will exhibit much the same performance, as with all LSI SandForce based SSDs, and KingSpec specifications are a bit conservative.  Typically, we might see specifications of 550MB/s read and 520MB/s write with about 80,000 IOPS.

BUILD AND COMPONENTS

The KingSpec E3000s SSD exterior casing is of a two piece smooth black aluminum with rounded silver edging and is only 7mm thick for use in ultra style laptops.  It is secured by four screws on the bottom of the SSD, one of which is covered by a quality inspection sticker that also acts as security tape.  Any damage to this whatsoever would void the warranty.

This memory has a product number of 29F16B16MCME1 and has a program and erase rating of 10,000 cycles. To keep this simple, this means that each memory module can be written to and erased 10,000 times and, as garbage collection ensures that all memory wears equally, it quantifies this as meaning the number of times the SSD can be written to.

In today’s world, SSDs are now typically being manufactured with memory capable of 3,000 program and erase cycles.  If we used the basic calculation of  (GB x P/E)/GB Written Daily, this would mean our 240GB SSD would last us 48000 days or 131.5 years if 50GB was written to it daily. If, on the other hand, the manufacturer had used 3,000 P/E memory, it would only rate at 14400 days or 39.45 years.

Now we can consider that there probably isn’t a consumer alive that is pushing 50GB through that SSD every day, just as there isn’t likely to be a consumer using the same storage medium for 40 years. Realistically, the importance of eMLC memory endurance is only the concern of the enterprise environment where we might see much higher volumes of data pushed through this SSD daily.

CAVEAT:  The use of this formula, as stated, is very basic and does not include such things as over provisioning, write speed and write amplification.  We are also NOT stating that any SSD will last 133 years, but rather, providing a time related example that displays how this SSD can last more than three times longer than same with 3,000 P/E memory.

Why is it that the majority of “Enterprise” SSDs are only available SATA interfaces and not SAS?

It is a combination of the fact that SATA is more common and, with respect to enterprise, there are much fewer SAS SSDs to be tested. We can compound this even further with the fact that these drives usually value considerably higher and many companies have yet to rely on such testing by SSD review sites.

This is correct. Just like PNY there will be shallow support for firmware and they will never get on the LSI supported drive list. If you are not on the LSI or Adaptec supported list, the first answer from support will be – you are not using a supported drive. End of support. The PNY Prevail reviewed here, I had to return due to ghetto wire (patch wires) which is pretty scary. I can only hope this company will update their firmware and fix the bugs quickly. PNY did not and was an epic fail. Also remember Mixing sata and… Read more »

That’s not entirely correct. All SF SSDs are on the supported drive list and FW is forwarded as validated. PNY is up to date and had to wait for exactly that.

Thanks for the input!

Awesome the black PCB and the 10 000 times P/E nand chip
