M.2 vs 2.5 SATA

[JohnCarlHenry]

Should I go for a 250gb Samsung 860 EVO SSD 2.5 sata or a 250gb Samsung 860 EVO SSD M.2?(it will be the sole storage of the PC)

Both of those are SATA drives AFAIK. The speed should be identical.

 

The fast SSDs use the NVMe standard.

[Crunken]

Go for an NVMe SSD instead if you want it to be faster. These two should be the same speed, m.2 is the form factor not the speed of the drive

[goto10]

for storage? if you can buy a bigger storage ssd it would be better, being both ssd sata, i would go for a bigger cheaper unit

look first M.2 cannot be compared to SATA.

you see the type of SSD are categorized int o two form factor. SSD and M.2. SSD which is the blocky type of hardware and M.2 which small Size

what you need to know, specificly about speed. its about M.2 Using Nvme or SATA or not.

two protocol which is SATA use cable and Nvme use pcle slot. ofc the nvme faster.

 

Speaking about ur question about SSD. if it for size, go M.2

for Performance go M.2 NVme.

As for my two cents.  SSDs that use the SATA interface will normally have a much bigger write endurance number.  m.2 SSDs suffer from the problem of being an m.2 form factor usually right next to the GPU or in the crossfire of a lot of heat dramatically reducing their lifespan in comparison to SATA based SSDs. A SSD using the SATA protocol is no faster over m.2 then it is over SATA.  And a lot of the time they end up being cheaper because you're paying for a less premium form factor.

but some of the mobo can cool down the M.2. but what you are saying its correct about the thermal problem.

Speed will be identical and often price will be the same too. The choice comes down to convenience factors.

 

• Depending on your case an M.2 may be preferable - if you don't have 2.5" mounts behind the motherboard it may provide better airflow. Many cases also have a limited number of HDD bays which you may want to save for larger (2TB+) mechanical drives.
• At the same time M.2 connectors are almost always more scarce than regular SATA connectors; 1-2 per motherboard compared to 4-6 SATA ports. If you later want an NVMe drive you may find yourself having to abandon the M.2 to free up the slot.
• There is also the issue of getting data off the drive if anything goes wrong. A 2.5" drive can be quickly plugged into virtually any machine (and if not then a $5 USB adapter will solve that) while M.2 drives may require more expensive adapters that can't be found at the store around the corner.
• On the flip side if you own one or more semi-modern laptops then being able to swap or perform hand-me-down upgrades with M.2 drives can be an advantage.

Personally my preference is for 2.5" drives when buying a SATA SDD, but that's because I have a lot of infrastructure for dealing with 3.5" and 2.5" drives and very little for M.2s.

Sometimes, but the larger form factor allows for a larger controller and will result in better sustained IOPS  (IOPS are what make your OS feel really snappy) as well as better sustained performance.  If entering the NVME world was a possibility then it would start to be worth it, but at this point you can get 256 GB very cheaply (at least in the US) as a 2.5'' SSD form factor.  As long as John doesn't mind having the larger form factor, it will probably provide a benefit in the end.

[phoenixflower]

They will have the same synthetic numbers.  Given the general location of the 2.5'' SSD is not on the motherboard where all the hot stuff is, it can generally have better sustained peformance, but it really depends on the motherboard configuration and if the m.2 SSD has a heatsink.

Neither , usually 860 evo , especially in those low capacities are overpriced to hell.. Tbh all "top end" sata are overpriced in the 240gb capacities (wd blue 3d,mx500,sandisk ultra 3d) unless you are in a country , that does not have good ssd availablity
