Most people now buy laptops for their computing needs and have to make the decision between getting either a Solid State Drive (SSD) or Hard Disk Drive (HDD) as the storage component. So which of the two is the better choice, an SSD or HDD? There’s no straight-forward answer to this question; each buyer has different needs and you have to evaluate the decision based on your needs, your preferences, and of course budget. Even though the price of SSDs has been falling, the price per gigabyte advantage is still strongly with HDDs. Yet, if performance and fast bootup is your primary consideration and money is secondary, then SSD is the way to go.
There are certain parameters you see relevant while selecting your SSD and few of them may not have a significant role in your selection, let’s explore the must know points before buying SSD Drives
1. SSD Disk Capacity
When you are planning to buy SSD then you can choose capacity based on your usage and requirement.
2. SSD Performance
Basically SSD performance are related to the Sequential Read, and Sequential Write speed that typically goes up to 500MB/s in reading and bit lower in write.
3. SSD Data Random Transfer Rate
SSD Random Write Speed and Random Read Speed is another benchmark to measure the performance of SSD. Random Read/Write Testing performs with small blocks of at random locations on the drive. Random writing means you pay more penalty for the disk to seek free space and write. Naturally, this process will be slow compared to Sequential Data handling.
4. Multi-Level Cell (MLC) NAND flash memory
When you are buying SSDs, you’ll run into two kind of memory: multi-level cell (MLC) and single-level cell (SLC). The primary difference is that MLC memory can store more information on each cell. The advantage here is that it is cheaper to produce, and SLC is often cost-prohibitive for the average consumer.
5. SATA III Support
Most SSDs use the Serial ATA (SATA) interface, but not all use the latest version and this can limit the performance of your SSD. This is because “SATA I” can transfer data at 1.5 Gbps, “SATA II” at 3.0 Gbps, and “SATA III” at 6 Gbps. To ensure your SSD has enough bandwidth to transfer data as quickly as possible, you want it to be compatible with “SATA III”. You’ll also want to make sure your computer is SATA III compatible as well. If not, “SATA III” capable drives will still work as all versions of SATA are backwards-compatible.
6. ECC memory
Error-correcting code (ECC) memory does what the name implies: it provides your SSD with the ability to detect and correct common types of data corruption so you don’t end up with unusable data on your drive. An SSD with ECC memory is more reliable.
7.SSD Brand, Warranty & Support
While selecting your SSD, it ‘s always advice to buy latest technology known brand for longer life and better performance.
