A solid state drive is an advanced form of storage technology that uses microchips to store data instead of physical disks. They have several advantages over traditional hard drives, including no moving parts and almost instant data access. They also use less power and are smaller, making them a great choice for laptop computers. In addition, SSDs typically have a better chance of surviving sudden shocks and drops than HDDs. They can also withstand extreme temperatures and magnetic fields.
An SSD uses a flash controller paired with NAND memory chips to deliver high read/write performance for sequential and random data requests. The memory chips are arranged in a way to optimize the performance of each block. SSDs are found in most modern computers, laptops, tablets and digital cameras, as well as in some smartphones and thumb drives.
Solid-state drives are available in a wide range of capacities and prices, making them accessible to many PC users. The cheapest models use 32-bit MLC (multi-level cell) memory, while more expensive options offer up to four times the capacity in 3D V-NAND.
Most SSDs are designed to run at very fast speeds, which is why they’re ideal for gaming and other applications that demand lightning-fast storage performance. The fastest SSDs on the market are capable of delivering read/write speeds that rival those of mechanical hard drives.
If you’re looking to upgrade your computer, B&H Photo and Video offers an excellent selection of SSDs to choose from. The WD Black SN770, for example, is one of the fastest SSDs around and is backed by a five-year warranty. The drive uses Phison’s E26 SSD controller paired with 232-Layer Micron TLC flash and communicates over the PCIe 5.0 x4 bus. It’s compatible with 12th- and 13th-Gen Intel systems as well as AMD processors that drop into the AM5 platform.
An SSD can improve the performance of your laptop, desktop, or tablet PC by reducing boot time and application loading times. It can also lower overall system energy consumption by consuming 30-60% less power than a traditional hard drive. Saving just a few watts here and there might not seem like much, but it adds up over the course of a year or two on a heavily used system.
Solid-state storage technology has its roots in the 1950s, when it was used to store data in early vacuum tube computers. In the 1970s and 1980s, solid-state drives became popular for supercomputers. However, they were still quite expensive for consumer use, and their storage capacity was small (2 MB-20 MBs).
Today’s SSDs are based on NAND memory. There are a few different types of NAND, but the vast majority use MLC and TLC memory. MLC is more cost-effective than SLC but has slower write speeds. TLC has even more storage capacity than MLC but suffers from a higher risk of bit rot than SLC.
