- What Is An SSD?
An SSD (Solid State Disk) is a hard drive where the primary storage medium is through Semiconductors (Non-Volatile Flash Memory Chips) rather than a magnetic media, such as in a traditional Hard Drive. In other words, an SSD is a NAND flash memory chip based storage device that replaces the mechanical Hard Disk Drive (HDD), the last analog device remaining in a computer.
- What Is The Warranty For RocketDisk's SSDs?
The MemoRight GT Series eSSD & MemoRight rSSD Series comes with a comprehensive 5 year warranty from MemoRight.
The Mtron PRO 7000 Series & Mtron PRO 7500 Series comes with a comprehensive 5 year warranty from Mtron.
The Mtron MOBI 3000 Series & Mtron MOBI 3500 Series comes with a comprehensive 3 year warranty from Mtron.
- Why Upgrade To An SSD?
SSDs are most effective for Server applications & Server systems, where I/O response time is crucial. Data stored on SSDs should include anything that creates bottlenecks, such as Databases, Swap Files, Library and Index Files, and authorization & login information. SSDs do not have any moving parts - while a traditional HDD has drive motors & needs to spend time spinning up the Magnetic Platters & the Drive Heads to access individual blocks, all the storage on an SSD is handled by NAND Flash Memory Chips. This provides three distinct advantages:
1. Faster data access with less than 0.1 milliseconds Access Time, & speeds of upto 130MB/s Read & 120MB/s Write.
2. Far higher reliability, with Hard Drive crashes virtually eliminated
3. Significantly less power usage
The most salient advantage of the flash-memory-based SSD is that it can improve the speed of the computer far better than the Hard Disk Drive. As it has outstanding durability and stability, and consumes little electricity, it is emerging as the next-generation memory for Computers & Servers. Enterprise applications place a premium on performance, reliability, power consumption and space. Unlike traditional Hard Disk Drives, Mtron & MemoRight SSDs have no moving parts, resulting in a quiet, cool storage solution that also offers significantly higher performance than traditional server drives. Imagine replacing up to 50 high-RPM hard disk drives with one Mtron or MemoRight SSD in your Servers; handling the same Server workload in less space, with no cooling requirements and lower power consumption. That space and power savings, for the same Server workload, will translate to a tangible reduction in your Total Cost of Ownership (TCO).
Drawing from decades of memory engineering experience, the MemoRight & Mtron SATA SSDs are designed to deliver outstanding performance and reliability, featuring the latest-generation native SATA interface with an advanced architecture of NAND flash channels equipped with single-level cell NAND Flash Memory for even greater overall performance and reliability. These SSDs deliver higher input/output per second and throughput performance than other SSDs on the market today - and drastically outperform traditional HDDs. These Mtron & MemoRight drives also feature low write amplification and a unique wear-leveling design for higher reliability, meaning that they do not only perform better - they last longer.
- What Are The Unique Features Of MemoRight SSD?
MemoRight is critically acclaimed as being the leading SSD manufacturer in the world, when it comes to enterprise-class, SLC server, workstation & laptop solutions. MemoRight uses the highest quality SLC NAND flash memory chips available in the world marketplace. The design of MemoRight SSD is centered around corporate users, who need incredibly fast performance & unique, 100% data integrity.
MemoRight released the current GT Series eSSD in late 2007, and other manufacturers still can not compete with some unique characteristics of MemoRight SSD:
-
All MemoRight's SSDs contain an "In Drive UPS" which ensures 100% data integrity at all times, which is key in the military, the enterprise & is proprietary to MemoRight. The "In Drive UPS" is a large capacitor, which flushes the cache upon experiencing any power offs or voltage changes. There is no need for a SATA command to make this happen. This is an automatic process which happens upon self-detection of power spikes, dips or losses. When the MemoRight SSD is powered off, the "In-Drive UPS" provides energy to flush the cache. There is a Schottky diode in place, which prevents the "In Drive UPS" from leaking back out into the enclosure. This capacitor writes the data in cache to the NAND flash memory chips in less than 0.3ms. So there is no need for "quiet time" at all. The data integrity features of MemoRight SSD is what has made it the 1st choice storage solution for the US DoD.
-
MemoRight SSD suffers absolutely no performance degradation over time. In other words, MemoRight SSD has 100% constant speed, at all times, regardless of environment or application.
MemoRight's second generation (2G) SSD is well into development and is scheduled for release at the end of Q1 2010. The preliminary performance benchmarks for this SSD are jaw-dropping, with hugely superior performance in every category to every other SSD in the marketplace. Expect MemoRight to continue to lead the way in SSD enterprise-class performance. They are the market leader & this is the most compelling reason for you and your customers to standardize on MemoRight SSD.
- What Are The Differences Between SLC And MLC SSDs?
Flash memory stores data in individual memory cells, which are made of floating-gate transistors. Traditionally one (1) bit of data is stored in each cell. This is Single Level Cell (SLC) flash memory. SLC memory has the advantage of far faster throughput speeds, lower power consumption & much higher cell endurance. However, as SLC stores only one (1) bit of data per cell, it costs more per GB of storage to manufacture.
Multi Level Cell (MLC) flash memory stores two (2) or more bits of data in each cell. By storing more bits per cell, MLC memory achieves lower manufacturing costs, but they have much slower transfer speeds, particularly in random writes, higher power consumption and much lower cell endurance than SLC memory. Although MLC beats SLC on density and cost per bit, SLC has the advantage for reliability, performance, power consumption, and operating temperature range. Normally MLC flash is intended for basic consumer products, where problems and data integrity is regarded as not being as critical as it is in the enterprise.
Sequential read speeds between SLC and MLC are comparable. However, any kind of random reads, any write operations, and random access times is not. MLC simply can not keep up with the speeds of SLC in the most common real life applications.
MLC supports only 10% of the number of erase/program cycles of SLC, which means that the endurance of SLC Flash is ten (10) times more than MLC Flash. MLC has this lower endurance rating due to the complex interaction of discriminating multiple logic levels reliably, coupled with the intrinsic failure mechanism of wear-out. This means that a data driven enterprise can expect their MLC SSD to wear out many years sooner than if it were SLC.
The reliability differences between SLC and MLC are plentiful, with many well documented issues regarding MLC available for online reading – with stuttering, freezing & compatibility issues being at the top of the list.
Remember, not all SLC has to be “unaffordable”. If you are an enterprise, cost per GB becomes secondary to cost per IOPS. If you are a consumer and an SLC SSD like the MemoRight GT Series eSSD is not in your budget, we encourage you to look at the Mtron MOBI 3500 Series. This product range is entirely SLC based, at extremely affordable prices.
- Are SSDs The Same As USB Flash Drives?
No. SSDs have a dedicated CPU (processor) supporting ECC (Error Correction Code) to reduce the risk of data corruption & ensuring that your data is stored safely. Reliability is increased by evenly distributing the data across all available cells (a specific location in each Flash chip) in the SSD. USB Flash drives do not have these features.
- What Is Wear Levelling?
Like all electronic devices, SSDs have a useful service life. In the case of SSDs, it is the number of times data can be written to an individual cell. Our MemoRight and Mtron SSDs contain a built-in wear levelling algorithm, which is a feature of the SSD that ensures all cells are worn down evenly, thus extending the useful life of the SSD. There is virtually no limit to the number of times data is read.
