I am in need of some storage to replace a Samsung 840 EVO 250GB SSD that (according to the tech who looked at it) is supposedly dead or dying.
The store I go to has the following options available in my budget:
https://www.umart.com.au/WD-Green-240GB-3D-NAND-2-5--SSD_41234G.html
https://www.umart.com.au/Kingston-240GB-A400-SATA-3-2-5-7mm-Height_39819G.html
https://www.umart.com.au/Crucial-BX500-240GB-3D-NAND-SATA-2-5-inch-SSD_47004G.html
Which of these is the best choice? Or is there something else I should consider (at a higher price)?

Or if I decide to go lower on budget and get a smaller disk (since I dont necessarily need the full 240GB) which of these would be best?

Those are all DRAM-less SSDs, so quite sub-optimal for a system/OS drive. I can't recommend any of them.

For a budget SATA SSD, the WD Blue 3D (or its brother the SanDisk Ultra 3D) or the Crucial MX500 are good choices. Samsung 860 Evo if you can splurge a bit. I'd say 250 GB is the minimum for a desktop/laptop system, and performance can really drop at lower capacities.

What, exactly, appears to be wrong with the current SSD?
 
The A400's are 'fine' as a general purpose upgrade over an exisitng 5400rpm type drive. Get a Crucial MX500 instead though. Unless you are doing tons or data writing you wont really notice the difference. All much of a muchness.

People sweat this stuff too much these days.
 
A while back I had a hardware failure that blew out my motherboard and the Samsung SSD in question (the guy who diagnosed my system and told me I needed a new motherboard also told me that the SSD wasn't working even on his known-good test rig so I figure its probably genuinely dead, thankfully I didn't loose any data in the process). My main SSD (500GB NVME SSD) and all my other hardware survived. I replaced the motherboard and CPU at the time but didn't replace the Samsung SSD. But now I have hit a point where I actually want/need the space that the Samsung was providing.

Speed is not a major concern here (since I wont be running apps of this, just using it as a data dump), price (and getting something that's reliable and has a reasonable lifespan from a reputable manufacturer) is the bigger concern right now.
Unless its somehow slower than the WD My Passport USB drive the data I backed up from the old dead SSD currently lives on, it will be plenty good enough (I mostly want this disk so I don't need to keep pulling out my external backup drive from its safe storage location every time I need a file that was on the dead SSD)
 
I've bought dozens and dozens of Kingston SSDs from V300 to A400 and none of them have failed over the 8 years or so I've been rolling them out for folks. They just work and are pretty cheap.
 
I wouldn't go under 240 GB (256 GB-class). Aside from that, it doesn't really matter that much. It's very hard for me to tell the real world difference between an NVMe 970 Pro and a SATA MX500 even though they are wildly different on paper. For ordinary use, nothing all that write heavy, I don't think DRAM-less makes any noticeable difference either. Just get the cheapest.
 
for kingston get the 2 letter drives (like UV line for kingston sata ssds) not that i have ever had a kingston fail on but i have never got a dramless kingston one before (there are far more negatives long term especially if you fill them beyond 60%, they can turn into a HDD after 60% in some cases as the lack of Dram means the page table has to be Read/Write directly from nand instead of from the Dram) the price diferance of a dramless vs dram based ssd not worth the downsides of a Dramless SSD and in a lot of cases your talking less than $10 diferance

WD blue Currant line of Sata SSDs are fine (that may change if they move to dramless on WD blue SATAS as they have on the NVME WD blues) kingston UVx00 , crucial MXx00 (any of them are fine even used) and samsung 850 or higher evo SSDs
