Question Samsung 850 EVO 250G - very slow read speeds

[rocktalkrock]

I have a Samsung 850 EVO 2.5" SATA III 250GB SSD which has very slow read speeds but always has normal write speeds. I have run numerous speed tests on 2 different laptops with Samsung Magician and i either get a slow write speed or the Samsung Magician program crashes, just the software crashes not the laptop. I do not understand why the write speed can be completely normal but read speeds are terrible. Is this SSD still worth keeping?

8 Years old roughly. I would say no generally. Early TLC drive I believe. Given the low capacity there are likely few chips (or a single chip) under the hood.

Why the read would be slow might have something to do with the controller going faulty.

Name brand replacements of 500GB or 1TB can be had for under $50. (870 Evo 500GB is $53)

Your showing a lot of crc errors is the disk connected with cables or does it plug into a socket?

It plugs into a socket.

It plugs into a socket.

Firmware update?

It might be time to copy off the disk before it decides to croak.

Samsung Magician says the firmware is up to date. I am using a 240G Kingston A400 at the moment but i was hoping to replace the Kingston SSD with my 850 EVO because it has 512 MB of DRAM cache and the A400 is DRAM-less. My brother gave me a newer laptop because i was having problems with my old core2duo laptop. I did not suspect the problems were caused by a faulty SSD, but that was likely the problem all along.
