Exam 220-1101 topic 1 question 163 discussion

When CompTIA says HDD, they literally mean hard disk drive not SSD. I think you have to pick the only HDD option. The question says that the person wants the "fastest possible HDD", so that is what you pick, not what would actually make sense in real life so don't worry about SAS being for workstations etc.

It says that the technician assessed which connections were available, but we don't know what those are. Since it specifically says the user wants to REPLACE the current HDD with another HDD (and there are no HDD options as answers) I'm going with the SAS since we know there's an available HDD connection and an SAS is designed to fit in an HDD slot.

NVMe SSD is much faster. As it is not Mechanical.

The best choice for the user's laptop is a 1TB NVMe SSD. NVMe (Non-Volatile Memory Express) is a high- performance storage protocol designed specifically for solid-state drives (SSDs). It is significantly faster than SATA SSDs and SAS hard drives, making it ideal for users who need fast storage for their laptop. NVMe SSDs also have lower latency and higher bandwidth than traditional hard drives, making them well-suited for data-intensive tasks such as video editing, gaming, and running multiple applications simultaneously. Additionally, NVMe offers more reliable data reliability than traditional hard drives, and is less susceptible to performance degradation over time.

SAS HDDs (Serial Attached SCSI) are the fastest type of HDDs available. They are commonly used in enterprise settings for their higher performance, reliability, and speed compared to standard SATA HDDs. The other options (NVMe SSD, flash drive, and SATA SSD) are not HDDs, so they don't fit the requirement for a 1TB hard disk drive.

The best choice would be A. 1TB NVMe SSD. NVMe SSDs offer the fastest performance among the options provided. They use a high-speed PCIe interface, which significantly improves data transfer rates and reduces latency compared to traditional SATA SSDs or HDDs. Here's a breakdown of why the other options aren't as suitable: 1TB Flash Drive: While portable, flash drives typically offer lower performance and capacity compared to SSDs and HDDs. They are not suitable for replacing a laptop's internal storage. 1TB SATA SSD: Slower than NVMe SSDs, but still significantly faster than traditional HDDs. However, NVMe SSDs offer better performance. 1TB SAS: While SAS drives are known for their reliability and performance, they are typically used in server environments and are not commonly found in laptops. They are also more expensive than NVMe SSDs. Therefore, an NVMe SSD is the best choice for the user who wants the fastest possible 1TB drive for their laptop. GG

A is the answer The keyword here is "laptop". Think a small form factor. The tech asseses what connections are available, then has to make a recommendation. The other solutions are NOT what you would see in a laptop which needs a small form factor solution recommendation. NVMe SSD comes in M.2 small form factor which would fit in a laptop. A SATA HDD isn't small form factor, SAS is an interface usually used to connect HDDs. Flash drive is a garbage answer. Most likely "A".

A flash drive isn't even an option, Sata isn't as fast as NVME and SAS isn't as fast as NVME. So the answer is A

Just off research.

SAS wont fit in a laptop. The eliminates SAS from the running. Since theres no HDDs remaining, you probably want to at least go with the fastest option, the NVMe

it looks like its very convoluted to use SAS on a laptop based on my searches, so it most likely is not SAS. NVMe SSD is the fastest, and is pretty commonly used with laptops. it is confusing that they said HDD and not just "storage drive" or something ambiguous though.

A. 1TB NVMe SSD NVMe (Non-Volatile Memory Express) SSDs are known for their high-speed performance compared to traditional HDDs and SATA SSDs. They utilize the NVMe interface, which allows for faster data transfer rates. In terms of speed and responsiveness, NVMe SSDs outperform both HDDs and SATA SSDs. While the other options may provide additional storage, they are not as fast as an NVMe SSD:

I understand the question asks for an HDD but the question is also saying they want to replace the hard drive in the LAPTOP. How does any of them other than the NVMe fit inside the laptop. Can someone explain why you chose D when a SAS drive wont fit inside a laptop.

Short answer: yes, it is! NVMe SSDs installed in a compatible device provide significant speed improvements over SATA SSDs and can improve the overall performance of your PC. Upgrading your PC or laptop rather than replacing it can breathe new life into your machine at a fraction of the cost.

Is the correct answer.

The technician check availability connector we don’t know which one so we go with the fastest on NVMe

NVMe (Non-Volatile Memory Express) SSDs are currently the fastest type of storage drives available. They offer much higher data transfer speeds compared to traditional SATA SSDs, flash drives, and SAS (Serial Attached SCSI) HDDs. NVMe SSDs use the PCIe (Peripheral Component Interconnect Express) interface, which allows for significantly faster read and write speeds. If the user's laptop has an NVMe slot available, it is highly recommended to choose a 1TB NVMe SSD to improve overall system performance and reduce boot and load times significantly. However, it's essential to verify that the laptop's hardware supports NVMe drives and has an available NVMe slot before making the purchase.
