Using a UPS to save SSDs

<< < (2/4) > >>

Dave Yeo:
I'm using a 2GB Seagate backup slim for backups, it has been fine. The extra speed of a SSD for backup is useless with OS/2 as our USB drivers aren't the fastest, even with USB3.1. I did partition it to about 1/2 GB partitions and formatted with JFS. The big downside is if chkdsk has to run, takes a long time. Best to keep the drive disconnected except when backing up and only partition what you need.

Dave Yeo:
Yes, that was a typo, 2TB HD.

Check out NVME. It can be your only "disk" in your machine, as long as the machine is new enough to be capable of booting from it. NVME SSD  is a LOT faster than SATA SSD. The cost is comparable.

Well, 1 GB will keep the backup size under control. I don't think you can even get sticks less than 32 GB any more, and they are more expensive than 256 GB sticks. Kingston is one of the netter brands, but if it is from 2006, you are pushing your luck.

NAS boxes are useful, if you need one. If you don't know anything about them, you probably don't need one. Same goes for RAID. RAID is not really supported by OS/2, so it is a waste of money. USB enclosures will serve the same purpose, for a simple system configuration.

Almost anything is better than Type A USB connectors (especially when used with USB 3.x).

Deep discharge is a killer. You want to be shut down, by the time it gets to about 50%.

No Wireless capability?
If printer and router are both wireless capable it gives you more options on where to site the printer - and there is no need to go tripping over long USB leads  :-)



Hi Andrew,

Regarding printers, forget long USB cables and get one with a network connection if it needs to be a long way away from the computer.  I have two Brother laser printers, one an all in one unit DCP9020cdw sits nearly 5 metres from my main computer while the other an HL3170cdw is upstairs with my other computers.  Being on the network they can be accessed from anywhere in the house, even the table near the front door for when friends bring something to be printed.

I recommend a laser printer because over time they save money - (no ink to dry out unless they have solved that problem) and all you need is the ppd file and the PSPRINT driver.

My 2 cents worth which may or may not be of help.
