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.
In a move that The SSD Guy wishes he had thought of for himself, SanDisk has begun to help corporations upgrade their fleets of notebook PCs by replacing their HDDs with SSDs.
SanDisk calls this program STAR for: “SanDisk Tech-Assisted Refresh”. According to the press release: “Through the STAR program, SanDisk relieves IT departments of having to manage all aspects of upgrading corporate laptops such as, endpoint inventory analysis, employee service scheduling, system upgrades, data migration, daily progress reporting, post-upgrade analysis and support.”
SanDisk points out that PCs slow down with disk utilization and software updates, lowering users’ productivity. Often faster storage can solve that problem.
This is not an altogether new Continue reading
Earlier this month Western Digital’s HGST division invited The SSD Guy to a launch of a number of products. On the HDD side there were:
- 6TB air HDD, HGST’s last air-filled enterprise HDD
- 8TB helium HDD, an incremental upgrade of last year’s 6TB helium HDD
- 10TB shingled helium HDD (pictured)
I view these as very solid evidence that HDD costs will continue to stay an order of magnitude cheaper than SSD costs, thwarting the price-per-gigabyte crossover that others have been predicting for years.
In fact, since my last post on the price crossover in 2011, very little has changed.
It’s safe to assume that the HDD industry will Continue reading
Seagate announced last week that the company had shipped a total of 10 million Solid State Hybrid Drives (SSHDs) over the lifetime of the product. This is far short of expectations by The SSD Guy and a number of other analysts and industry participants.
Why were our expectations higher? There were a few reasons:
- The hybrid drive can be viewed as an evolution of the DRAM cache already incorporated into nearly all HDDs today. Replacing or augmenting an expensive DRAM cache with a slower, cheaper NAND cache makes a lot of sense.
- An SSHD performs significantly better than Continue reading
SanDisk has just introduced the Ultra II SSD, an upgrade of the company’s original Ultra drive. The new device is being promoted as a 28 times faster HDD replacement that offers faster boot-up, longer battery life, and shock resistance, in an approach that appears to be a throwback to the early days of SSDs where the point was to sell the technology rather than the product. Although the press release shows sequential read & write bandwidth numbers of 550 and 500MB/s, neither the press release nor the online product literature even mention IOPS or other measures that are now commonly used to compare one SSD against the other.
SanDisk does tout the fact that this SSD uses Continue reading
This study breaks the market into 23 application types, and provides an explanation of each along with forecasts by major application category.
Virtualized systems will drive the greatest 5-year average unit shipment growth, at 85%, although the data center will retain its leadership in enterprise SSD consumption. Overall enterprise SSD unit shipments will grow at an annual average of 32% through 2018.
Since SSD prices are cost-based, with roughly 80% of the cost coming from flash chips, NAND flash price swings will cause Continue reading
On 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 results of the Storage Performance Council’s SPC-1 report, show Kaminario surpassing last year’s record performance by 20k IOPS.
Interestingly enough Kaminario set the 2012 record using DRAM while this year the company was able to do it with its fourth-generation all-flash K2.
Why is the SPC1 test so highly respected in Continue reading
Violin Memory and Microsoft have jointly announced a novel way of harnessing the power of Windows Server software. Violin will be shipping its memory arrays with a special version of Windows Server 2012 R2 pre-installed on the embedded server that manages the internal operations of Violin’s all-flash array.
Violin explains that native support of specially-optimized versions of Windows Server and System Center that have been tuned for an all-memory array will provide improved performance and economics for large-scale enterprise cloud deployments.
The system can internally run Continue reading
Today SanDisk announced that the company is now 25 years old and celebrated the fact by ringing the NASDAQ opening bell.
It’s intriguing to The SSD Guy that the company has reached 25 years, and has reached annual revenues of about $6 billion dollars, yet one of the founders is still the CEO. Sanjay Mehrotra has been leading the company since the retirement of co-founder Eli Harari, and has Continue reading
