I5 is more than enough.
Even 4gb ram is enough but not saving for going 4gb from 8gb.

If you are doing maintenance for him (re-installing windows periodically, etc), I would still get SSD. He will be happier for fast booting speed, loading speed of those basic applications. You will be happier for faster reinstallation time of windows, etc.

Look into the new hybrid drives. Traditional hard drives with 16~32gb SSD built in as caches. They are marketed as SSHD

The frequently accessed files (basically Windows and your usual programs) will be kept in the cache.

I have a Mac and bought a 120 GB hard drive, thinking I'd have plenty of space for my OS and apps. (I thought I only used about 80 GB of space). But I forgot that other users on the computer also use space on the boot drive and it turns out that I used about 115 GB!

I thought it would be worth it for the speed. But I don't really notice a difference. I still kept it on the SSD for a long time (over a year). Because of the severe lack of space, I can't even upgrade my OS X to 10.9 because I don't have space to install it. I finally ran Blackmagic's disk tester and found out that the SSD is no faster than a regular hard drive.

Whoops!

So I'm transitioning back to the hard drive, where I have a ton of free space. Luckily, I've been running daily clones of my boot drive, so all I need to do is tell the computer to boot of the hard drive instead. Changed back quickly and now I can upgrade to 10.9.

Still gotta figure out why my SSD is so slow.

Even the worst SSD's on the market are faster than any HDD... Except perhaps for 15K RPM HDD's, which are not used on mac, for sure.

Hey FOZZY!

Calling you out. So let me get this right again, Install HM2 on SSD. Postgres on SSD.

For Handhistories that I want to import which is taking up all my computer space now... ~10-20gb worth. I can transfer these hand histories to a HDD and will get the same performance from the SSD when loading HEM/HUDs etc?

And currently all hands are on my computer but i only have 10gb left of SSD. I dont want my SSD to die! How can I go about moving the original hand histories to my HDD and still keep my hudstats etc?

Thanks fozzy

You have 10 - 20 GB of text file hand histories to import? This is going to take a ton of space (way more than the 10 - 20 GB of original files) on the SSD in postgresql and the database parent folder.

We pull the stats from the postgresql database once the hands have been imported. Auto imported hands get archived but manual imported hands do not get archived. It doesn't matter where the hands are at when imported/archived in terms of performance for the database/hud. It may have a slight effect on import speed but once imported performance is dependent on the performance of the drive postgresql is installed on.

You can simply cut/paste the original hands to the HDD and configure HM2 to archive auto imported hands there as well but if you have 10gb of free space and move 20gb more off it then 30gb of free space will not be enough room to import those hands/files IMO. That is likely 10 - 20 million hands as a rough estimate.

In HM1 there are a lot of tables that deal with a specific hand played by a specific player. In HM2 we don't have these tables, instead, for player related hand data, we use a flat file approach. Each player has his own folder and each file represents a single day. Each line within the file is a tokenized version of a single hand with incredible amounts of detail. Your overall HM2 spaced used (DB + Files) is about 2/3 of HM1 and we store probably 2-3 times as much info plus it can be accessed many, many times faster and allows us to do some things that wouldn't be possible otherwise, many of which are yet to come. If you don't want the space in your Roaming folder due to C: file space or something like that, we do give you the option of storing this data anywhere

General rule is 1 million hands = 10 GB.

In reality it's: 1 million hands
HM1: 6.8 GB
HM2: 4.3 GB
PT4: 13.6 GB

So with a 10 million hand database you need as SSD of at least 60 GB (Windows) + 100 GB = 160 GB. We use 1 million = 10 GB (instead of 6.8) because when you want to perform a vacuum/analyse or backup/restore a database it will require a LOT of disk space to perform such a task.
You want to generally have more free space on the drive than your database size.

thanks fozzy.

I checked my HH files its actually taking up ~6.5gb of space. These hands are alraedy imported to HM can I delete them? or do I still need them?

And for future references I can import from my HDD and have HH files saved on there right? it would be same performance ? And you said ~10gb text handhistory files after imported to HM2 would be ~20-30gb space on my comp? so for 6.5gb of hh it would roughly take up 14-20GB of space on my comp even if the HH is saved on HDD?

am i understanding this correctly?


and how would HM2 perform if i installed postgres and HM2 say on a USB3 drive? would this work?

You can, but I would not. If you ever have a corrupt database and can't restore a database backup (or never made one) you need those original hands to be able to recreate your database. I would recommend you leave them on your HDD. Zip them if they are taking up more space than you would like. I keep mine in my google drive on my HDD so they are also backed up in the cloud.


Yes. Any reduction in import speed between importing them from a HDD and SSD is generally negligible and once they are imported/parsed into postgresql on the ssd they are no longer needed for generating reports or hud stats.


You misunderstood. 10 GB of text files would take a minimum of 43 GB (4.3 GB per 1 million hand estimate) but you need double that space so you have plenty of free space for vacuuming and backing up. You should estimate 10 GB per 1 million hands.

Depending on the file type, and if they are cash or tournament hands, original hand histories are typically about 1 million per GB so your 6.5 GB is likely 6 million hands so you should have at least 60 GB of free space before you start importing to be safe.

1 million hands in HM2 takes 4 - 5 GB of space and even more if you have NoteCaddy enabled (and even more if you use custom NC definitions/stats/badges from a add on coaching package). I would estimate 6.5 GB of text hand history files to take 25 - 30 GB of SSD space at a minimum and quite possibly more. And however much space it does take you will want at least that much extra free space afterwards so you can do things like vacuum and backup your database periodically.


I would not recommend this. I have not done any testing of this recently but from what I remember when I tested this with HM1 it was terrible performance compared to having it on an internal drive.

Agree, SSDs are really a "must have" for a poker PC
