BP4's read-performance, when tested, falls slightly below the
specification & our expectations: the write performace doesn't - it's
exactly as specified: SAO,TAO,DAO . . . all the way to DAO RAW+96 . . . it
16x, yes, it takes just over 5 minutes to write a full 650Mb CD; & on our
dual-CPU test-system running Windows 2000 we found it next to impossible
to get BURN-proof to kick in, unless running a couple of instances of a
CPU stress-test. We couldn't make a coaster.
good results with all media used; but would recommend visiting Sanyo's tested
16x SCSI-burners are
thin on the ground: Yamaha have the [unpleasantly noisy] 2100S - a faster
all-round reader, but inferior - & non-'burnproof' - writer,
especially of HSRW media: in the next
month or so they'll release a 20/10/40 burnproof-equivalent model
using the Oak LSI.
Plextor are reliably
rumoured to be very near to releasing a SCSI-version of their splendid
16/10/40 'burnproof' model: this is likely to be a near-identical writer
& phenomenally good DAE reader - roughly as good as their 40TSi; snags
are expense - & that in the US it'll be packaged with worthless Adaptec
software [lucky Europeans get WinOnCD3.8OEM].
SCSI-models more - er -
intimately related to the Mirai CDR-BP4-M include the
Waitec 'T-Rex'; the Nimichen/Brainwave CRD-BP4-N ['Generic'; kit comes
with Nero; 4.31 firmware]; & the Iodata CDRW-SB1610B [many BP4/1400
variants, including FireWire & USB] - there are
are, of course, many 16/10/40 BURN-proof IDE/ATAPI models very closely
related to the OEM Sanyo BP1400: a good clue to kinship is whether the firmware version
number - "5.31" [say] - is similar to a recent Sanyo firmware
It is possible the BP4
& related model's DAE performance may be improved by a major firmware
revision: we have reported the C2 pointer issue to Mirai,
who are pro-active in encouraging Sanyo to focus their product
At present, many users
- not just the demanding - will want & need a first-class SCSI
CD-reader like the Plextor 40TSi to complete Mirai's BP4 package &
balance & unleash its fine performance as a writer.
Given the fine value
of the Mirai kit, & the profound desirability of all-SCSI CD-device chains,
this is a practical - if noticeable - extra investment: such a combination
represents the current state-of-the-art in CD read/write performance &
will make a tempting alternative to the Plextor 16/10/40 SCSI-burner - at its
handsome price when & if released.
At the time of
writing, the Mirai CRD-BP4-N represents a pretty irresistible standalone alternative to
the Plextor PX-W1210S BURN-proof SCSI 12-speed; the buyer must balance the BP4's second-generation BURN-proof,
faster writing & much better value against the Plextor's DAE
read-quality . . . .
& a deserved good name for continued development & first-rate support.
We didn't test the BP4 with any
UDF application - InCD, DirectCD, InstantCD etc - if these dubiously
reliable applications are of use to you, cdrinfo has an early-firmware BP4/1400
doubtless will soon provide a BP4 review with many, many numbers &
"performance" with Adaptec software.
Feurio website has just now added accurate data on the BP4's DAE
qualities & write
capabilities - typically, this went up just after we had completed 130
hours of test-runs.
Burningissues' verdict? . . .
. . er . . . no pompous faffing about with stars or marks out of

evaluation sample & with full knowledge of alternative & upcoming
