Q: Should I choose the Intel 545s 512GB or an NVMe SSD for a laptop or desktop upgrade?

Choose the Intel 545s if your system only supports 2.5-inch SATA drives or if you want a simple drop-in replacement for a hard drive. Choose NVMe if your system has an M.2 PCIe slot and your goal is higher throughput for heavier file transfers, scratch-disk work, or more performance-focused builds. The Intel 545s is appropriate for compatibility-first upgrades, while NVMe is the better path when the platform can use it.

Q: Should I buy the Intel 545s 512GB or the Crucial MX500 500GB?

Choose the Intel 545s if you want a proven SATA SSD with DRAM-backed TLC storage, strong everyday responsiveness, and hardware AES 256-bit encryption in a standard 2.5-inch form factor. Choose the Crucial MX500 if price is similar and you want a very common alternative with broadly comparable real-world SATA performance. Across reviews and community recommendations, these two drives are usually treated as same-class SATA options, so the decision is often driven more by price, availability, and brand preference than by a large speed gap.

Q: Should I get the 512GB Intel 545s or a lower-capacity SATA SSD?

Choose the 512GB Intel 545s if the drive will hold Windows, applications, and several modern games or project files. A lower-capacity SATA SSD works for a basic boot upgrade, but 512GB is the more practical tier for users who want to avoid filling the drive quickly. In this class, moving up in capacity is usually a usability decision more than a speed decision, since SATA itself caps peak throughput well below NVMe levels.

Q: Is the Intel 545s 512GB worth choosing over an older Intel 540s?

Yes, the Intel 545s is the more sensible choice over the Intel 540s if both are available at similar pricing. Intel positioned the 545s as the successor, and reviews note that it moved to Intel's 64-layer 3D NAND while targeting the same mainstream SATA upgrade segment. That makes the 545s the better fit for buyers who want the newer generation rather than an older SATA model with a similar use case.

Question 1

Does this include a 2.5"-3.5" mounting adapter for mounting in a 3.5" drive bay?

Accepted Answer

Good question.  No, it does not include the 2.5" to 3.5" adapter.  If you can,  buy it at the same time.  Search "2.5 to 3.5 adapter "

Question 2

Does it include a SATA cable and/or 2.5"-3.5" mounting bracket?

Accepted Answer

I had to  supply my own SATA cable and mounting bracket.

Question 3

does it work with XP ?

Accepted Answer

Yes, it will work like any hard drive.  That said, XP does not support trimming which means the drive will slow over time.  It will still be way faster than a spinning platter drive, but it's not optimal to run on XP.  Also, you need to make sure you turn off any automatic defrag for this drive as it will simply reduce it's ultimate lifespan.  You really should run it on a modern OS, but I realize that some connected devices are old and only work with XP.  Again, it will work fine and be faster, just realize performance will lag over time.

Question 4

I bought the Intel 545s and I'm a lInux user.  Does anyone have any insight into using the Intel ssd firmware update tool?  I'm not successful getting it going with usb or cd.  Otherwise the SSD works great, fast as heck, or as fast as sata gets. (1st world problem)

Accepted Answer

Haven't tried it on Linux,  but used it on a Windows machine. I downloaded the ISO (OS independent) for the latest firmware update (002C) for the 545s, burned it to a boot CD, and used it successfully. However, there was one glitch:  although it was supposed to bypass the OS, after the update I could not connect to the Internet - turns out that for no apparent reason it completely messed up the Windows  Internet settings and thus prevented connecting. It had wiped them, entered a different IP address, and disabled DHCP in the TCP/IP protocol suite, requiring a complete reset.

Question 5

How in the world can a user rate this latest SSD offering from Intel with four (4) stars and state "It performs worse then (sic) my 2+ year old SAMSUNG 850 EVO which is a fantastic drive."? It seems time & time again Intel - Intel! - has been unable to design/manufacture a SSD that can realistically challenge the offerings of Samsung and other top-of-the-line consumer SSD manufacturers.

Accepted Answer

I have been using an Intel 730 as my C: drive in Windows for over a year.  No issues.  I'm more concerned about reliability than absolute speed.  My 545 is running my virtual machines (VMware), with no issues.  Again, my concern is reliability.  I've had no issues with Intel SSDs.  The speed of both of these SSDs is fully adequate for my use.  Note, my older (and smaller) Intel SSD had 5 years of use with no issues.  Again, reliability is my first priority.
