The computer and electronics super geek thread

Been looking at SSD's, and am currently thinking:

The 2.5in SATA market is already almost dead, with few real options. The 870 Evo was the last new model Samsung made and that was years ago. I don't want to buy another again. The Crucial MX is sold out everywhere.  WD is just rebranded Sandisk.  

So thinking----M2 nvme on a pcie adapter card.  Then I can hopefully move it to my next new mobo (and mount it directly) whenever my big upgrade happens.  

Price-wise, M2+adapter is the same or cheaper than a 2.5in.

I'd say that's definitely the way to go.  Not only could you mount it directly to a new mobo with more NVME slots, you could fill all the mobo's NVME slots and still stick the adapter into a free PCIe slot (which a future mobo will almost definitely have) and have even more NVME storage.

And I went ahead and ordered that combo---even though my board's 2nd pcie x16 slot is only PCIE 2.0 (vs the 1st slot being 3.0), and the adapter only uses x4 bandwidth---that should still be much faster than SATA.  And when it someday gets moved to a new board with multiple M2 slots, then it'll be faster still.  

One of my credit cards is doing 5% back this quarter with Amazon, and Amazon is offering 1 month free trial of Prime again, so free next-day shipping  plus 5% off.   So went with them instead of BestBuy or Newegg etc.  (yes, Newegg is a shell of its former self, but still better than Amazon much of the time IMHO for PC parts).  

Decided on another 990 Evo Plus, same as my (almost)new OS drive.  Everywhere still seems to say it's just about best thing ever.   

::edit:: Seriously, Best Buy dropped the price $10 within minutes of me ordering from Amazon?  :[

You don't have a SSD yet? Yes, 2.5in SSDs are dead and M.2 is the state of the art but it sounds like you need a new system.

On a side note I converted my old 250Gb Samsung SSD from 2014 into a USB drive with an adapter from Amazon. Works really well and is connected to my nVidia Shield to hold media files.

I do, I was just looking to see what was available as a replacement for the dead one, which was a 2.5" SATA.  My only M.2 slot is already being used by my OS drive.

I didn't want to buy a new mobo solely to be able to have 2 direct-mount M.2's simultaneously.  And 2.5" seems pretty dead, if you want a name brand.

2.5" drives aren't really dead. At least not the form factor, in the data center. It's just that we've hit the 6-Gbit/s bandwidth limit on SATA and with M.2 far outpacing that bandwidth (cuz it uses PCIE), there's no headroom left in the SATA protocol. Even SAS (SATA's datacenter cousin) can't keep up topping out at 22.5-Gbit/s. The 2.5" format are still used in NASs/SANs cuz as that format is easy to work with in large scale (the drive is a 2.5" drive but runs on the M.2 protocol/PCI-E bus, see Kioxia's CD-series datacenter drives). Once nice thing about old SATA 2.5" SSDs is that they don't suffer from heat issues like NVMe drives cuz the bandwidth limit is lower, generating less SSD controller heat vs NVMe.

But at the consumer level, taking into price+quality+availability----it looked surprisingly dead.  I kept wondering why I couldn't really find much, until I realized, it looks like almost everyone jumped ship already to pure M.2.  And I don't doubt the PS5 is part of the reason.  A zillion M2's were sold because of it (I bought one!).  And so competition/development of that segment of the consumer market was and still is high.  

My now-dead 2.5in SATA was in the coolest spot in the PC and all alone in a suspended cage.
