What is SSD (Solid State Storage) storage

SSD (Solid State Drive) is a game-changer. It is the most common storage device today. You can find it in computers, notebooks, servers, NAS (Network-Attached Storage), and other devices. Comparing them to HDDs (Hard Disk Drives), SSDs are faster and they are more resistant to physical shock.

SSD is a non-volatile storage device that uses flash memory to store the data, they don’t have spinning disks and movable read and write heads. SSDs run silently. All of these factors are very relevant reasons to replace your old HDD with SSD (if possible).

However, SSD has a limited lifetime number of writes. You can check the SSD lifecycle and health state by using the application provided by the SSD manufacturer (if the manufacturer doesn’t have one, try with third-party applications). For example, you can use Samsung Magician Software to check the health state of Samsung SSD. In the case below you can see that Samsung SSD 870 EVO Plus 500 GB M.2 is 10.5 TB written and Samsung SSD 860 EVO 1 TB SATA is 4.6 TB written. In addition, to that, you can also have a look at the transfer rates.

The origins of SSDs dates from the 1950s. The first flash-based SSD was developed in 1991 and it could hold 20 MB of data. Around 2007, the first PCIe-based SSD was announced. Today you can purchase an SSD with a capacity of more than 10 TB. In the coming part, we will walk you through the different SSD types and we will guide you on how to buy the SSD that fits your need.

What SSD types do exist on the market?

The SSD is connected to the device using an interface that supports the specific protocol and speed. These interfaces and/or disks are known as SATA and PCIe. This is a section about them.

If you are running an older computer or notebook or other device, you can connect an SSD disk to a SATA interface located on the motherboard. The SATA interfaces are also used for connecting SATA HDDs (Hard Disk Drives) and SATA CD/DVD Drives. There are three versions available: SATA I, SATA II, and SATA III. They support different speeds/transfer rates. The first generation supports 1.5 Gb/s transfer rates, the second generation supports 3 Gb/s and the latest one supports 6 Gb/s transfer. SATA disk has two SATA connectors. One is used for communication with motherboard and data transfer and another one is for power supply. For example, you could go with Samsung 870 EVO is a SATA SSD that supports up to 2 TB of disk space.

As SATA was limited to 6 Gb/s transfers, the disk manufacturer decided to create an SSD that can connect to and use PCIe speeds. PCIe interface provides minimal latency, high bandwidth, and high performance. The interface is optimized for NAND flash and next-generation SSDs and can deliver four times the performance of SATA 6 Gb/s. This sounds impressive, isn’t it? There are different form factors of PCIe disk such as M.2 NVMe, M.2 SATA, mSATA, and others. If you decide to buy a new computer and laptop, your machine will be probably powered by an M.2 NVMe disk.

If you would like to replace your existing HDD or SATA SSD with a new SSD M.2 disk, your motherboard must support the PCIe M.2 interface. If it doesn’t, you can purchase NVME SSD to PCIe 4.0 Adapter Card you install in the PCIe port. With this card, you can add an NVME SSD to your motherboard without M.2 slot. In most cases, it is plug and play PCIe adapter card.

What metrics are relevant for purchasing SSDs?

There are different factors you need to consider when purchasing SSD, including the capacity, read and write speed, performance, and vendor support. The purpose is also important. If you are looking for SSD for gaming, you will not buy the budget SATA SSD, but a more powerful one. There are different vendors that make SSDs including. According to the market share from Q2 2021: „Samsung currently has a 24.4 percent market share in SSDs. Western Digital is second with 18.8% and Kioxia is third with 12.6%. In terms of storage capacity, Samsung leads with 34.9%, followed by Western Digital (16.6%), Intel (10.3%), and Kioxia (9.1 percent ). Seagate only excelled in overall unit sales (0.3%) and storage capacity (0.1%). (0.7 percent).

What to do if SSD is faulty and you can’t access it?

This could happen to anyone. You or someone else might accidentally delete data from your SSD, or it could happen that your SSD is not operational anymore, and you can’t access your private or business data. The recovery procedure is very much complicated due to fact that you might experience hardware (controller chip failure, electronic component failure, etc) logical problems (accidental deletion of data, firmware corruption, software errors, etc). Our Team powered by data recovery professionals can support you in regards to recovering the lost data from health or failed solid-state drives. We are looking forward to addressing all of your data loss SSD-related queries. You can request a free diagnostic and evaluation LINK.
