Summary :

DRAMless SSD

Are DRAMless SSDs useful for anything? A lot of users are discussing this question on forums. Now, this post of MiniTool will analyze its pros and cons in detail. In addition, several best buy DRAMless SSDs and a tool to migrate OS will be introduced to you.

Quick Navigation :

What Is DRAMless SSD

When it comes to DRAMless SSDs, it is inevitable to mention DRAM cache. Many people take the DRAM cache as an important component when buying an SSD: It’s a small amount of very fast storage that works as a superior layer of cache on a NAND flash storage, and it can improve the sustained speed, response time, and endurance of an SSD.

However, there is a situation that the DRAM cache has little and even no impact on SSD performance. So, many manufactures like Crucial, ADATA, and Kingston released DRAMless SSDs that have little DRAM cache.

A lot of people are still confused if it is worth buying a DRAM-less SSD. The following part will analyze its pro and cons in detail. Let’s keep reading.

Is It Worth Buying DRAMless SSD

Compared with RAM based SSDs, DRAMless SSDs have their own pros and cons. Let’s start exploring.

Pros

There are 3 main advantages of a DRAMless SSD. The most obvious advantage is that most DRAM-less SSDs are cheaper than many RAM based SSDs. For example, 1TB Crucial BX500 DRAMless SSD only costs $89.99, while a 1TB Crucial M.2 DRAM SSD costs $104.88. If you choose an affordable SSD for mass game storage, then a DRAM less SSD in high capacity could be a good option.

Under the same price, a DRAM-less SSD has equally fast read speed compared with a RAM based SSD. So, you can consider choosing a DRAMless SSD as a boot drive. This is because booting computer is mostly random reads but with very little writes.

DRAMless SSDs do most of their work instantaneously, which means that there is less possibility of data loss if a power outage occurs. That’s why DRAM-less SSDs have better stability.

Cons

Many users reported that a DRAM-less SSD has a shorter lifespan than a DRAM SSD. In addition, an obvious disadvantage of DRAMless SSDs is that their write speed is slower. For example, a Crucial BX500 SSD has 540MB/s of sequential read speed, while the sequential write speed is 500MB/s.

However, many people reported that the read and write speed of a DRAMless SSD is almost equally fast in reality. Do you want to know their actual read and write speed? Let’s keep reading.

Benchmark the DRAMless SSD

A lot of users may want to test the read and write speed of new-buy SSD/HDD. How to benchmark hard drive/SSD? Here MiniTool Partition Wizard is highly recommended. It is a trusted multifunctional partition manager that can help you benchmark SSD, extend partition, convert FAT to NTFS, recover lost data, convert MBR to GPT, etc.

Here is a full guide on how to measure SSD performance with MiniTool Partition Wizard.

Step 1. Click on the following button to download and install the MiniTool program, and then run it to enter the main interface.

Step 2. Click on Disk Benchmark from the top toolbar, and then select the drive letter of your SSD from the drop-down menu and specify its parameters based on your needs. After that, click on the Start button.

Tip: Here you can set the transfer size, test mode, queue number, total length, and thread number. The larger span of the transfer size you set, the longer time this test will take.

Step 3. Wait for some time to complete this disk benchmark. From this test result, you will know some important information including transfer size, random/sequential read, and write speed.

Is DRAM less SSD worth buying? The answer depends on what’s the most important factor for you. If you want to purchase a cost-effective SSD, a DRAMless SSD might be a good option. If you seek an SSD with a higher write speed and longer lifespan, we recommend you choose an SSD with DRAM.

Best-buy DRAMless SSDs in 2021

There are many different brands of DRAMless SSDs on the market. Which one should you choose? If you are also confused about this question, you can refer to the following 4 best-buy DRAM-less SSDs.

#1. Crucial BX500

Crucial BX500 SSDs should be one of the most popular and reliable DRAM less SSDs. This series of SSDs focus on boosting overall system responsiveness for all computing needs. Its read speed can reach up to 540MB/s and write speed can be up to 500MB/s. Crucial provides a lot of capacity options for the BX500 SSDs so that most people can find a perfect storage capacity.

Another outstanding point of the Crucial BX500 SSD is its price as it is cheaper than most other DRAMless SSDs. So, it is an excellent value buy especially for someone who seeks a fast SATA SSD on the cheap. Well, a drawback is that this SSD comes in only 2.5-inch form factor without M.2 option.

Here are detailed parameters of Crucial BX500 SSDs:

  • Capacity: 120GB, 240GB, 480GB, 1TB, and 2TB
  • Interface: SATA
  • Sequential Read: 540MB/s
  • Sequential Write: 500MB/s
  • Form Factor:5 inch
  • NAND Flash Type: 3D TLC/QLC NAND
  • Warranty: limited 3 years
  • Cost: $89.99/1TB

#2. ADATA SU760

ADATA SU760 is another best-buy DRAM-less SSD on the market. This SSD delivers a higher speed on sequential read and write than Crucial BX500. Its read speed can reach up to 550MB/s and the write speed can speed up to 520MB/s. In addition, it was designed with SLC dynamic caching and DRAM buffer, which is a pretty good feature for improving the performance DRAM-less SSD.

ADATA SU760 SSD
