• A solid-state drive (SSD) is a data storage device that uses solid-state memory (SSD grade NAND) to store data on “blocks” of memory
• General SSD Components:
• PCB
• Interface (SATA)
• Controller
• NAND
• Array. Configurations x8, x12, x16

What is an SSD?
4/13/2012 Commercial Division
NAND Flash
• Each SSD grade NAND component is comprised of “blocks” where data is stored
• Two different ways to store – Use the whole Block or use the Page within the Block
• PNY SSDs store data using Page-based management
• Keeps the SSD performing at optimal levels – write speed doesn’t drop dramatically after extended use
• Requires sophisticated controller to handle this process
Controller
• The Controller is responsible for communicating between the SATA interface AND the Blocks of NAND to store data, organizing the data into “Pages” within each Block

SLC vs. MLC
4/13/2012 Commercial Division
MLC Multi Level Cells
MLC memory stores 2 bits per memory cell.
With 2 storage areas available, MLC cells have to be tested with 4 different electrical levels (empty / full x 2).
To check the level of use on flash memory cells, the system sends a request to the transistor which will examine the content in sending different levels ofelectrical flow :
SLCSingle Level Cells
SLC memory stores only one bit per memory cell.
With one storage area per cell to check, the transistor sends 2 different electrical levels (answers empty / full).
• Fast access• Low level of storage / cell
• Answers approx. 3 x slower• Twice the storage for the same physical size.
atios
• Sequential Read & Write – measured in MB/s, higher is better (think max
speed)
• Random Read & Write – measured by writing 4KB data files in a
completely random pattern over a portion of the SSD drive, higher is better
(think typical speed)
• Simulates the type of random access a user would experience while
running an OS
• Random Read & Write IOPS (Input/Output Operations Per Second) –
measured in 10,000’s(K) operations – 20K, 30K, 50K, etc.
• Simulates the type of heavy workload and random access an
Enterprise/POS system would experience
Key Performance Terms

Sequential vs. Random/IOPS
4/13/2012 Commercial Division
Random Access
Radom Read/write gets directly to the data/adressa Wheeler It is on the storage area.
Sequential Access
Sequential read/write actions are performedin a continuous way.
To access data stored in the 15th block, the system will go directly to the location.
To access a data store in the 15th block, the system will have to read the block 1 to 14
prior getting to the location.
IOPS (Input Ouput Per Sec) are based on sustained operations, meaning they measure the maximum amount ofread/write speed performed in 30 sec.
As OS’s use mostly small files in random access, the most important IOPS measurement is based onRandom 4k read/write amounts. It deals with the maximum amount of 4k read/write cycles performed inone second.
HDD vs. SSD
4/13/2012 Commercial Division
Current operating systems mostly perform random operations with small-sized files. Large files aren’t accessed thatoften.
RANDOM Access (Random Read/write speed) is essential in measuring the speed of a computer. It impacts applicationlaunches when others are already running.

- Fast access on large files when stored in thesame area of the disk
- Random writes- Slowed access when datas are spread all
around the disk
- Fast read/write on small files- Constant access time wherever the datas are
stored
- Performances loss over time called « SlowDown» phenomenon

SSD are used as replacement for traditional Hard Disk Drives. As they have no moving
parts they are typically less susceptible to physical shock, more durable, silent, have
lower access time and latency, and use less power than HDD.

HDD a PR Issue• Why do people buy an SSD?
– Performance (speed, durability)
– Price
– Power consumption
• Bottom line question: "How long will my SSD last?”
Fact: Traditional HDDs are one of the most historically failure prone electronic
devices.
Fact: Consumers & Corporations worry about protecting their data from HDD
failure.
Solution: SSD’s solve this problem.
Endurance is the area that users are concerned about over performance.
4/13/2012 Commercial Division
SSD Endurance• Flash memory endurance is the parameter describing how many times
each cell can be programmed and erased.
• You can write a page but you have to erase a block.
• There are several MLC Flash endurance grades available on the market: 10k, 5k, 3k, 1k and <1k.
• Wear leveling in the controller can help maximize the P/E.
• For a given controller technology, the Flash endurance has a linear impact on the SSD lifetime.
• Over Provisioning can create a Spare pool of Blocks to mitigate impact.
• Different use cases will affect Endurance differently.

TBW=Terabyte write=the amount of data that can be written to the drive/PB=Petabyte Values shown are estimates based on a specific use case, actual numbers will vary based on individual use cases
Endurance – Use Case• Client: Storage Drive Used for Mostly Reading Data, Some Writing:
– A typical user with a laptop, desktop or mobile device surfing the web, streaming music and video, or running programs are performing read operations. A user would be writing data while running their operating system, installing programs, transferring data to their system or saving files. For this type of user an SSD with a rating from 1K to 3K should last 10 years or more.
• Compute: Storage Drive Used for Mostly Writing Data, Some Reading:
– If someone is running an enterprise server or workstation they’re typically running larger programs or performing various transactions which require more writes. For this group 5K to 10K rated SSDs would be able to withstand this type of data throughput.
• Enterprise: Storage Drive Used for Heavy Writing of Data and Archiving:
– Large corporations, cloud deployments and sensitive data (NASDAQ, Medical, IT) would require 10K rated flash since those machines are performing millions of small write operations in those systems.
