SSD in Bangladesh
Finding the best SSD or solid-state drive for your specific system and needs is key if you want the best gaming PC or laptop, or even if you just want a snappy productivity machine. A slow storage drive often leads to a big bottleneck, forcing your processor (even if it’s one of the best CPUs for Gaming) to waste clock cycles, waiting for data to crunch. To speed up your write and read speed, you need a speedy SSD. To figure out which is the best SSD, we test dozens of drives each year and highlight the best drives here.
Now that we’re past the great deals we saw for SSDs during the holiday season, we’re looking forward to the pending announcements at Computex 2022. We’ll also see the first signs of PCIe 5.0 SSDs this year, so keep your eyes peeled for the latest news.
What Is an SSD?
SSDs got their name—solid state—because they use solid state devices under the hood. In an SSD, all data is stored in integrated circuits. This difference from HDDs has a lot of implications, especially in size and performance. Without the need for a spinning disk, SSDs can reduce to the shape and size of a stick of gum (what’s known as the M.2 form factor) or even as small as a postage stamp. Their capacity or how much data they can hold varies, making them flexible for smaller devices, such as slim laptops, convertibles, or 2 in 1s. And SSDs dramatically reduce access time since users don’t have to wait for platter rotation to start up.
SSDs are more expensive than HDDs per amount of storage (in gigabytes (GB) and terabytes (TB)), but the gap is closing as SSD prices decline at a faster pace that HDD prices year over year.
SSD vs HDD: Which do you need?
Are you running out of storage space? Has your hard disk slowed to a crawl? Or are you simply looking for optimal computer performance? It may be time for a hardware upgrade. But should you get a cheaper hard disk drive or a faster SSD? We’ll explain the differences between HDDs and SSDs in terms of speed, capacity, cost, and lifespan, then show you how to keep yours clean and fast with specialized optimization software.
SSDs are faster, more durable, more compact, quieter, and consume less energy. HDDs are more affordable and may offer easier data recovery in the event of damage.
As long as price isn’t the determining factor, SSDs come out on top — especially since modern SSDs are just about as reliable as HDDs.
Comparing SSDs and HDDs
- HDDs are a legacy storage technology that use spinning disks to read/write data.
- SSDs are faster and more power efficient than HDDs.
- HDDs are priced lower, but SSD prices are dropping.
Why are SSDs useful for laptops?
SSDs are often used in laptops because they’re non-mechanical. Solid state drives require less power, which translates into better battery life. While lower-priced laptops still come with traditional, cheaper hard drives, most mid-range to high-end machines come with an SSD.
While hard disks have moving parts, solid state drives are shock-resistant. If you drop your laptop while the read/write head of a hard drive is in motion — which it usually is — it could result in data failure. This doesn’t happen with SSDs.
But it isn’t always an either/or choice. “Hybrid” computers have both drive types — the operating system (OS), apps, and the most-used files are installed on an SSD, while other data sits on an HDD, which is typically larger and less expensive. Using your SSD to run your OS and apps is a great way to increase SSD performance.
On our Mac with an SSD, sequential reads are nearly 56 times faster and small 4K read operations are about 226 times faster. Windows takes just 10 seconds to boot, and there is no visible delay when launching Chrome — it’s just there. Upgrade to an SSD if you want to speed up your Mac or make your PC faster.
Types of SSD in Bangladesh?
There are two different types of SSDs: Serial Advanced Technology Attachment SSDs (SATA) and Peripheral Component Interconnect express SSDs or Non-Volatile Memory express SSDs (PCIe/NVMe/PCIe-NVMe).
SATA SSD in Bangladesh
When we speak of SSDs, we usually mean SATA based 2.5” Solid State Drives even though the NVMe drives are also technically solid state devices. To overcome the problem of moving mechanical parts, the storage in SSDs is not on a physical disk but rather on a semiconductor device.
SATA isn’t as fast as M.2 PCIe or a PCIe add-in card, but the majority of desktops and many laptops can take 2.5-inch SATA drives and many doing typical mainstream tasks users won’t notice the difference between a good recent SATA drive and a faster PCIe model anyway.
NAND based flash technology has been in use for thumb drives for quite some time before making its way into SSDs. In SSDs, the data is stored on NAND based on flash memory instead of physical metal platters.
As there is no magnetic read / write head, SSDs are significantly faster and could easily reach the speeds set by the SATA interface.
But the main problem with SSDs is their cost and low storage capacity. While you can get SATA HDD with capacities as high as 16TB, you will hardly find SSDs greater than 2TB (there are few 4TB SSDs but the cost is astronomical when compared to HDDs). Some common storage sizes of SSDs are 120GB, 256GB, 512GB, 1TB and 2TB.
NVME SSD in Bangladesh
M. 2 SSD is a small form factor solid-state drive (SSD) based on the industry-standard M. 2 Micro-contact Interface Standard (M. M2) that conforms to the Computer Industry Specification for Small Form Factor Storage Devices (CISF). However, the M. 2 SSD does not require any special driver in order to be used in Ultrabook laptops, or computer cases.
As mentioned earlier, NVMe Drives are still solid state drives, they use solid state semiconductors to store data. But the difference between SATA SSDs and NVMe drives is the interface technology.
SATA SSDs are limited to the same 6Gb/s transfer limit as the HDDs despite being significantly faster. This is a limitation of the SATA interface and not the SSDs itself.
To overcome this limitation of SATA and unleash the full potential of SSDs, a new interface is developed, which is based on PCIe interface (the fastest possible interface between a CPU and an external device apart from the RAM). This interface is called Non-Volatile Memory Host Controller Interface Specification or simply known as NVMe (NVM Express).
With such great transfer speeds comes a great price. The cost of NVMe drives is very high and is much higher than SATA SSDs. Despite its high cost, NVMe Drives are slowly becoming popular for fast read / write speeds in heavy work loads such as gaming, video editing and other intensive tasks. Now-a-days, even laptops and mini-PCs are coming with M.2 NVMe slots.
One of the popular form factors of NVMe drives is M.2 and particularly M.2 2280. An important point to note here is that SATA SSDs are also available in M.2 form factor but the pins and slots (B Key and M Key) are different for SATA M.2 and NVMe M.2 drives.
When to Choose SATA SSD or NVMe?
Go with SATA SSD:
- If you already have a SATA HDD and need a faster hard drive as boot-up drive
- Upgrade old desktop / laptop with SSD to increase performance
- If you are flexible on price
Go with NVMe SSD:
- If budget is not an issue
- Need high read / write speeds for a high-end performance PC or gaming PC
How to install an SSD in your PC or laptop?
Data storage devices are getting increasingly smaller, faster, and cheaper. They have largely replaced the optical discs that used to be the primary means of storing data on computers. With a solid-state drive (SSD), you can speed up your computer without having to sacrifice performance or having to replace parts of your hard disk.
SSDs have been around for several years, but have only been getting more popular in recent years. The reason is clear: they are much faster than traditional hard disks, which were once considered the only way to store data on computers.
There are two types of solid-state drives:
- They’re manufactured with flash memory instead of mechanical disks that must spin at very high speeds (usually 7200 RPM). This also means they can be much smaller and lighter; some SSDs are as thin as a penny!
- They’re designed as solid-state drives because they don’t contain any moving parts which wear out over time. This also means they do not need power supplies or batteries if you use them on battery power only (as is the case with many laptops).
What does this mean for you? Well, it’s great if you plan to use your computer for an hour or less per day and want to optimize speed for this purpose. It might not be such a good choice if you plan on using your computer all day long like I do and do not need extremely fast storage on every page visited — though I should point out that it is still possible to get an SSD for less than $100 without sacrificing too much performance for my purposes — but in general it does make sense for people who want immediate access to their files whenever they need them rather than having to run a separate slow storage device.
The first type (and likely most common) SSDs come in M-series, which offer sequential read speeds up to 3200 RPM (which is enough for most people) while offering sequential write speeds up to 4500 RPM. The second type (and likely most uncommon) are T-series, which offer sequential read speeds up to 3600 RPM while offering sequential write speeds up to 5200 RPM.
