Solid State Drives Explained
Solid State Drives Explained
An SSD is a solid-state drive that is a solid-state storage device that uses integrated circuit assemblies as memory to store data. Although a SSD functions like a hard drive (HDD), an SSD contains nonvolatile flash memory which has no moving parts to break. This results in a much faster drive and instant boot and load speeds because there are no mechanical moving parts. SSDs are not only much faster, but they are also much more durable and reliable because there are no mechanical moving parts to break. SSDs also differ from HDD in that they consume much less energy, again because there are no moving parts…this allows for much longer battery life for laptops and less energy consumption for desktops and servers. Installing an SSD along with a memory upgrade is the best way to improve your system.
Are all SSD the same? Definitely not! There are many key attributes to any SSD drives. When comparing SSDs, simply comparing storage capacity is not apples to apples…
- Capacity. Yes capacity is capacity. NEMIX RAM Solid State Drives, for example are available in 240GB, 256GB, 480GB, 512GB and 1TB. There are other manufacturers that offer different capacities such as 500GB.
- Transfer Speed. This is key…Today’s best SSDs use 6 gigabits per second transfer rate (Gbit/s). NEMIX SSDs (SATA III & M2-2280) utilize minimum of 6 Gbit/s. Please compare SSD transfer speed when shopping for SSDs.
- Flash Memory. The newest SSDs including all NEMIX RAM SSD use 3D TLC NAND-based flash memory. 3D TLC NAND is a type of non-volatile memory that retains data when power is lost. Make sure you compare SSDs utilizing the newest flash memory technology.
- Form Factor. Today’s Internal SSDs come in a variety of form factors. The most popular and widely used is the 2.5” SATA III along with M.2 2280. SATA (Serial Advanced Technology Attachment) is the standard form for connecting an internal storage drive to the system’s motherboard. Other form factors may also include M.2-2242 SSD, M.2-2260 SSD and mSATA SSD. These are much less used form factors however that may be used in proprietary systems. Other proprietary SSDs include Enterprise based SSD that are typically using SAS interface, PCI-Express 3.0 interface or PCI-Express 3.0 x4 / x8 interface. Enterprise SSD are typically separated from client based SSDs by distinguishing the Flash Storage Controller (often called SSD controller) and the non-volatile NAND Flash memory used to store data. In a nutshell, Enterprise SSDs are built using higher standards of retention and materials allowing for usage in much more extreme temperate environments.

5.Interfaces. The SATA is the most prevalent interface for connecting internal storage drives including HDD, SSD and optical drives. The SATA interphase has undergone three major revisions, resulting today’s newest format SATA III. Other Interfaces include PCIe. Peripheral Component Interconnect Express (PCIe) is a computer bus standard with extremely high bandwidth potential which makes it the fastest bus option that most systems have available. Like the SATA bus standard, PCIe has undergone several revisions over the years and is still improving speeds. PCIe 2.0 is the most common PCIe revision found inside computer systems.
Apple / Mac SSD: Apple started releasing systems with solid state drives in late 2010. Apple utilizes a wide variety of SSD interfaces including proprietary SSD connectors. For a complete guide to Apple SSD, please refer to our Apple Upgrade Center https://www.nemixram.com/apple-memory-upgrades.
Apple Mac Pro SSD:
NEMIX RAM specializes in production of early MAC PRO SSD which are a proprietary connection. If you have a MAC PRO and need an SSD, you will not require an adapter if you purchase our SSD. NEMIX Mac Pro SSD drives are ready to be installed into any Mac Pro system other than the Mac Pro 2013.
