After blowing nearly $300 on my 100GB SSD card for my MacBook Pro. I thought I'd try out the 'lower' end of the spectrum. A 32GB ADATA S596 Turbo.
128MB Cache Buffer.
Read: "260 MB/s"
Write: "60 MB/s".... which is actually a label over 210 MB/s.

I've spent all evening counting bytes and by hand and getting the latest gparted so that everything was aligned.

Performance is Meh.

Then I compared it to the 1.5TB Seagate I just pulled from my ZFS array. 5400 RPM. 32MB Cache. Nothing special at all.

SSD Card:

Code:

root@htpc:~# hdparm -tT /dev/sda
/dev/sda:
Timing cached reads:   858 MB in  2.00 seconds = 429.01 MB/sec
Timing buffered disk reads:  534 MB in  3.00 seconds = 177.78 MB/sec
root@htpc:~# dd if=/dev/zero of=/dev/sda5 bs=10M count=100
100+0 records in
100+0 records out
1048576000 bytes (1.0 GB) copied, 17.4983 s, 59.9 MB/s

Regular old 1.5TB Drive:

Code:

root@htpc:~# hdparm -tT /dev/sdb
/dev/sdb:
Timing cached reads:   850 MB in  2.00 seconds = 424.63 MB/sec
Timing buffered disk reads:  320 MB in  3.02 seconds = 106.10 MB/sec
root@htpc:~# dd if=/dev/zero of=/dev/sdb bs=10M count=100
100+0 records in
100+0 records out
1048576000 bytes (1.0 GB) copied, 9.91265 s, 106 MB/s

I was hoping for some Read or Write difference by a power of 2 to justify the cost. Something.

Not to mention it 'hangs' at random times. It linux actually killed it and remounted it read only once. Every random boot it insists or performing an fsck... if it gets that far.

No wonder NewEgg has the "Limited Replacement Only Return Policy."

If you're going SSD, spend the money on an Intel. If you can't afford an Intel but want speed. Go for a RAM disk. My next endevor is going to try and sell this on Craigslist and get a 4GB stick of RAM. There's a script on UbuntuForums of how to take your entire boot drive and turn it into a squashfs and load it into RAM at boot then setting up cron to sync it back to disk regularly and rebuilding the squashfs image.

Thanks for the warning. Too bad you had to make the experience :o
I just bought a Vertex 2 60GB for my Shuttle XS35GT. I know its overkill but i wanted to be safe.

BTW: Its not all about r/w speed but seek time.

Mild hijack... Im looking at vertex 2 and XS35... you tried Aeon yet? Can it handle with with a nice SSD?

OCZ too, don't forget about OCZ.

I think I'm running an OCZ in my MacBook.

When OS X can boot faster than Ubuntu Minimal then you have some problems.
