Windows 7: SSD, Which one?

When I built my current machine just a year ago, 8GB RAM cost me $228, now it is $137.
In 3 years we'll have Windows Twilight Zone 256 bit, spinning drives passe', SSD's the norm, IE14, Intel and AMD merge and we'll have 12 core CPU's at 6+Ghz.

Maybe. Doc can let us know, he's been to the future.

Yes, but in a year when we have all the new fancy stuff...we are going to only be 1 year away from things we cannot even imagine.

Well, in a moment of weakness, I just plunged for an Intel 320 series, 80 gigabyte SSD. $160 at New Egg, discounted 25 or 30 from previous price.

This is a third gen drive, replacing the X25M series. Only 1 review on New Egg and I could not find any reviews of this particular size in this particular series.

All I intend to put on it is Windows. I hope to never buy another boot drive.

I just checked Intel's site---there are no firmware updates, so I guess all is going well with the drive so far.

I can't find any benchmarks either. Maybe I'll make some and post them in a week or so. I gather performance varies a bit with these things, depending on size.

Didn't order any mounting hardware--I'll probably go the velcro/duct tape/cable ties route.

Cool ignatzatsonic, please keep us updated when you get it installed.glad you pointed out that is a newer drive than the X25 series, didn't know that.

Never? Huh, I bought my SSD about 18 months ago and I intend to replace it without question when I build a new computer. Things are always going to improve.

My Intel SSD is secured with Velcro.

I assume you will use the SSD for the OS. The OS requires a fast access time and the Read/Write speeds are of minor importance. This said, it does not really matter whether you get a cheaper Gen2 or a more expensive Gen3 SSD because they typically both have 0.1ms access time.

I opted for 60 and 90GB OCZ Vertex2 for three Windows7 systems and two 80GB Intel Gen1 for two Vista systems. They all work very well (one since 2 years). I would not go overboard at this time because tomorrow they will have somthing better. The 90GB Vertex2 cost $145 at Newegg - that would be the most I would spend.

Yeah--I had sworn I wasn't going to buy until I could get at least 64 gb for under $100, either Intel or Crucial. I was leaning toward Intel due to a possible reliability advantage.

So much for my iron will. Apparently, I'm just another fool with a credit card, trying to prop up the GDP. That's my picture in Webster's next to "impulse buyer".

PParks: Not sure I meant that literally, but the truth is if I can't live with the overall boot and response time of this thing, I should probably hang up my computing shoes. I'm sure I'll have plenty of other PC related things to spend money on and I do grow weary of drive shopping. My data is growing only about 70 gigs per year, so if I can get boot drives off my list, I may be able to go 3 or 4 years without even a new storage drive.

Is there any particular software good for benching SSDs that will show both sequential and random read/writes like I occasionally see in articles??? I'd like to post them on this forum as it seems all the reviewers thus far are testing only the ultra-high capacity drives of this newer generation.


Here are the alleged specs, from Intel documents. I don't think these specs are significantly different from earlier generations, but the capacity has gone up.

Sustained sequential reads

40GB up to 200 MB/s
80GB up to 270 MB/s
120GB up to 270 MB/s
160GB up to 270 MB/s
300GB up to 270 MB/s
600GB up to 270 MB/s

Sustained sequential writes

40GB up to 45 MB/s
80GB up to 90 MB/s
120GB up to 130 MB/s
160GB up to 165 MB/s
300Gb up to 205 MB/s
600GB up to 220 MB/s

Read latency 75 microseconds

Write latency 90 microseconds

Random 4KB Reads

40GB up to 30,000 IOPS
80GB up to 38,000 IOPS
120GB up to 38,000 IOPS
160GB up to 39,000 IOPS
300GB up to 39,500 IOPS
600GB up to 39,500 IOPS

Random 4KB Writes

40GB up to 3,700 IOPS
80GB up to 10,000 IOPS
120GB up to 14,000 IOPS
160GB up to 21,000 IOPS
300Gb up to 23,000 IOPS
600GB up to 23,000 IOPS

I may be wrong, but I think sequential or random does not make a big difference for an SSD. Much more important is the blocksize. For that kind of measurement, I like Atto. Example:

Thanks for that WHS. I will check it out.

I've read that sequential means little, but that random performance is meaningful, particularly of 4k to 8k blocks.

I cannot relate to that. But I will check whether I find something. If you have a link, I may get a headstart.
