Are all SSD made equal?

No, not all SSD are made equal, there are different categories of FLASH memory, and occasionally a newer technology is invented, thus expanding the variant.

Today, the marketplace is serves with two types of FLASH memory, the SLC (single level cell) and MLC (multi-level cell).

Are FLASH Memory and SSD the same thing?

Technically they are not the same, SSD are classify as drive category, while FLASH are classify as memory technology, while most of the SSD in the market today are made of FLASH memory to store data, instead of rotating disk medium like hard disk drive, people often use both terms interchangeably.

Are SSD better than the traditional hard disk drive?

Yes and no. SSD are by far faster than the traditional hard disk drive, due to its design using solid state materials, unlike the traditional hard disk drive that still employs servo motor (spindle) and mechanical arms for seek and write. The only tradeoff in SSD is the capacities, but as technology improves, it will be a matter of time before SSD match the terabyte capacity of hard disk.

Also in terms of energy cost, SSD consume less power than hard disk, since there are no moving parts involves.

Do I need to do TRIM regularly with LiteON SSD?

No. LiteON SSD is design with Instant Restore, this is similar to TRIM command, except Instant Restore is perform in real time, user do not need to execute a TRIM command in order to remove the unwanted block of data.

Does controller makes a difference?

Yes, LiteON SSD is design with Marvell® server class controller, one of the best in class in SSD technology. If FLASH memory is the heart on a SSD, controller is the brain of the SSD, it manage and handle all the processing, and data handling, ensuring speed and data reliability all the time.

Does SSD write and read performance degrade over time?

Yes. Once a new disk like hard disk or SSD is use, constant write, modify and deletion of files will result in a cluster or spread of data in the disk, in the traditional hard disk, fragmented disk occurs, in SSD, this is called dirty drive. When a dirty drive occurs, the write or read process takes longer due to the need to process the information in different cell, this is when the degradation occurs.

With LiteON TrueSpeed™ SSD, the disk write and/or read are guaranteed to perform near or equal a new drive performance.

How do I know if my SSD will really help in performance?

In everyday we process information with our computers, four process occur with our storage, (1) the write or data being written into storage, (2) the read or the data being access for use or process, (3) the modify or data being update with newer information, and (4) the delete or data being wipe off from storage.

The bottleneck or constraint is in the write function, the longer it takes to write your data into the storage, the longer the wait for your computer to do the next process. The faster it writes the data into the storage, the more tasks can be accomplished by the computer. Therefore consistent write performances in a SSD such as LiteOn TrueSpeed SSD™ guarantee performance and efficiency.

How do I know which SSD is right for me?

SSD like hard disk, are market with a benchmark, many of these benchmark will show a significant difference between brand and model, some of these benchmark will provide misleading information. Therefore when selecting a SSD, three main factor to look for,

  • The FLASH memory use, does the vendor indicate which brand of FLASH is being used? What type? The reliability, the quality and the performance of the product will pretty much be told by this information.
  • The controller used, if the FLASH is the heart of the product, the controller is the brain of the product, a server grade controller like the one made by Marvell will ensure reliable and consistent performance.
  • The firmware, this is the soul of the product, this indicates what the product will do and can do for you, a good design firmware guarantees the FLASH and the controller will work all the time without failure. This is the intangible part of the product.

How is FLASH Memory differing from regular memory?

FLASH memory, like EEPROM, can indefinitely store the data even if power source are remove, whereas DRAM that are used in computer, losses the data once the power is remove.

How reliable are FLASH memory?

Flash memory comes in different grade and different quality, ensuring a long lasting investment in SSD will need to be guaranteed by the quality of the FLASH memory itself. LiteON SSD FLASH are made by Toshiba®, it comes with a multi-year warranty, giving the end user a peace of mind in the SSD investment.

I saw the price, I still can’t afford it.

The cost of SSD per GB have drop significantly over the last few months, if we are to look at the SSD cost alone, the price may still be expensive than the hard disk, but the total cost of ownership is less than what hard disk can provide. Power and energy saving, time save with the speed and performance of the SSD compare to hard disk, investment cost as SSD last as long as hard disk if not longer.

Is there also read performance to consider?

Yes, as mentioned, one of the process occurs other than write is the read, running a spreadsheet, database application, or enjoying multimedia file in your computer, relies in how fast it can read the stored information in your SSD, the faster it reads the data, the less lags or delays in the process, the better is the users experience.

What are SSD?

SSD stands for Solid State Disk, a product that is mainly made of solid state parts, without any mechanical moving parts. SSD that are found in the market today are made using FLASH Memory, although there are still some SSD that are made using combination of RAM with some form of battery backup and FLASH.

What are the difference between SLC and MLC?

Single level cell stores memory in single level cell, which result in faster, reliable and lower power consumption. Whilst MLC stores memory in multiple levels per cell, this allows each cell to store more data (bits) than the single level. Therefore in the same form factor comparison, MLC store more data than SLC, and in cost comparison, MLC cost less than SLC on a per GB basis.

What is dirty drive?

Dirty drive is similar to fragmented hard disk drive, when a user use a new drive, the data are written in sequential manner, after prolong use with write and delete being perform over time, some of the cell in SSD (sector in hard disk) will contain deleted bits, SSD will retain is deleted bits and marked as garbage for block deletion later.

What is FLASH Memory?

FLASH memory is a non-volatile computer storage chip, it can be electronically program and erase. FLASH memory is primarily used in memory cards, USB flash drive, solid-state drives .

What is Lite-On True Speed and what benefit does it give to end users?

True Speed is a system that allows Lite-On manufactured drives to deliver real-life sustained high-performance. This means that end users experience consistently fast read and write speeds across the long life-time of their SSD drive. True Speed is not simply based on the server-grade controller and other advanced hardware used in our SSD solutions; it consists of complementary elements which include in-house firmware and an extensive burn-in procedure.

 

In some cases other manufacturers produce drives that experience drastic slowdowns in write performance after a relatively short period of use. They may even quote performance figures using optimized test results with artificial all 0 or all 1 test data. The True Speed system prevents drastic performance loss , and our performance tests are undertaken with more realistic random data sets,. This ensures happy and satisfied end users are in both the long-term and the short-term.

What is the other advantage of SSD?

Weight, speed, robustness are among the few advantages, speed such as boot time is typically half of that required for a hard disk. Read and write speed is several times faster than the hard disk.

Energy saving and eco-friendliness is a wow factor, SSD consume less energy to operate, energy require for boot up or wake up is zero compare to hard disk that will require spindle motor to boot, speed up, then the seek arm to move and access data.

Reliability is also the biggest factor in the quick adoption of SSD; as no moving part is require by SSD, the product is reliable even when bump and shock occurs.

What is TRIM function?

Trim command is an Operating System (OS) supported function, such as Windows 7, this function will inform the SSD controller which data blocks are no longer in use, and can be deleted.

What is TrueSpeed?

TrueSpeed is a LiteON proprietary technology, that employs and Instant Restore algorithm, LiteON SSD regularly perform a garbage cleaning similar to TRIM, except this is done without user intervention, and are done in background process.

True Speed not only clean the dirty drive for better performance with instant restore, but also manage the use and reuse of memory cell to prolong the life cycle of the SSD.

What should I look for when choosing SSDs for notebooks or desktops?

Whether an SSD is being used in a notebook or desktop, as a main disk or boot disk there is a set of key factors to consider before choosing an SSD. The first is performance and not just initial out-of-the-box performance statistics, but sustained long-term performance statistics. Now that SSD use is entering the mainstream, users are becoming increasingly aware that with some brands the initial performance used in marketing material is unrelated to the performance level experienced a relatively short time later. A few brands offer systems to prevent this problem primarily those based on Lite-On's True Speed system.

 

Secondly quality, SSDs offer high capacity storage and users expect drives to store every piece of data totally reliably. To ensure that your drive has this reliability select a manufacturer that fully tests every drive and uses high-quality NAND flash from a major brand such as Toshiba. Ideally look for a maker that puts their SSDs through more than 20 hours of burn-in testing, because the longer the burn-in test the lower the chance of data being stored on unstable cells.

 

Finally warranty, many manufacturers talk about quality, but the most direct proof of their certainty in the quality of the product is the length of warranty they are prepared to offer. We back our products with a 2 year warranty giving value and confidence to our users.
