MLC vs. eMLC – What’s the Difference?

eMLCFrom time to time IT managers ask The SSD Guy if there’s an easy way to compare SSDs made with MLC flash against those made using eMLC flash.  Most folks understand that eMLC flash is a less costly alternative to SLC flash, both of which provide longer wear than standard MLC flash, but not everyone realizes that eMLC’s superior endurance comes at the cost of slower write speed.  By writing to the flash more gently the technology can be made to last considerably longer.

So how do you compare the two?  OCZ introduced MLC and eMLC versions of the same SSD this week, and this provides a beautiful opportunity to explore the difference.

As you would expect, the read parameters are all identical.  This stands to reason, since Continue reading

OCZ Comes Roaring Back with NVMe SSD Debut

The OCZ Z-Drive 6000It’s really something to see a company recover from a big challenge, and signs of that happened this week with OCZ’s introduction of a new NVMe-based PCIe SSD they call the Z-Drive 6000 series.

This replacement for the company’s Z-Drive 4000 series is a complete redesign with an obsession for performance.  OCZ tells me that they moved from a 2-hop design to a 1-hop by using the PMC Princeton PCIe SSD controller, and have passed the University of New Hampshire Interoperability Labs’ compliance tests to NVMe 1.1B compliance.

But how does it perform?  Well the 1-hop design helps reduce latency (which is just starting to overshadow IOPS in users’ minds) and the latency of this SSD is significantly lower than competing NVMe SSDs: between 25-30μs, figures that OCZ tells me are very consistent, a big plus for enterprise applications.  As for IOPS, the device can perform under a 70/30 Read/Write load at 330K.

The 6000 series is provided in both standard MLC and eMLC for those who want the security of eMLC and are willing to sacrifice a little performance to sleep better at night.

This product is a good fit for the market needs, and shows how devoted OCZ and its parent Toshiba are to providing high performance in the SSD marketplace.

 

OCZ: Bankruptcy Certain, Outcome in Question

OCZ Corporate HeadquartersOn Wednesday OCZ announced that its bank accounts had been seized by one of its creditors and that the company would file for bankruptcy, but it did not commit on which of two courses of action it would take:

  • To file for bankruptcy and sell itself as an ongoing business to Toshiba
  • To file for bankruptcy and liquidate

If the company is sold to Toshiba the bankruptcy court will require an auction to be held to assure that the price that Toshiba pays is the best price that the company can get.  This means that there is still the possibility of another company actually acquiring OCZ.  Although Seagate was rumored to be interested there are certainly others who are also preparing bids.

OCZ has good technology and a loyal retail customer base, but one year ago Continue reading

The Week of CEO Changes

SSD Companies that Changed their CEOs Sept 17-19This week has gotten off to an odd start.  On Monday OCZ CEO Ryan Peterson resigned, after having built the company from a supplier of PC cases, power supplies and DRAM for gamers into a leading SSD maker, and then launching a successful IPO.  On Tuesday STEC’s CEO Manouch Moshayedi announced (via an SEC filing) that he will step down “pending resolution of a civil complaint filed against him by the Securities and Exchange Commission.”  Finally today Virident announced the hiring of Mike Gustafson of BlueArc repute to become CEO while former CEO and co-founder Kumar Ganapathy shifts his focus to business strategy, new product development and strategic partnerships.

What will Thursday and Friday bring? Continue reading

DensBits Debuts with eMMC Controller

DensBits Promises Higher Performance While Reducing CostDensBits, a flash memory controller company, has just introduced its new DB3610 “Memory Modem” eMMC controller for 3-bit or TLC flash.  The controller is the first to use DensBits’ new technology which the company claims can coax better reliability out of 3-bit flash than most controllers can out of 2-bit MLC, to provide important cost savings to OEMs.

Read and write performance is also said to be nearly on a par with 2-bit MLC.

DensBits’ Memory Modem is a blend of Continue reading

Intel Jumps Into the PCIe SSD Market

Intel's 910 PCIe SSDIntel has gotten into the fast-growing and lucrative market for PCIe SSDs.  The company has announced a PCIe SSD, the 910, that provides the high performance you would expect of a PCIe drive with the quality guarantees that customers expect of Intel.

Who could blame them?  Fusion-io has become a Wall Street darling for creating the PCIe SSD market, and still rides it to continually growing revenues.  LSI is fascinated by the growth of its Warp Drive.  Micron attained a significant design win at EMC, Texas Memory Systems (TMS) has had success in its own narrow markets, and Virident, OCZ, and STEC have also participated in the PCIe SSD’s market growth.

Intel’s 910 consists of four Hitachi SAS SSD Continue reading
